The Dungeon Anarchist's Cookbook

Carl, Donut, Katia, and Mongo enter the fourth floor, the Iron Tangle, aboard car 20 of a Red Line subway train. They have ten days before collapse, and Carl now carries a 100,000-gold crawler bounty. Donut's Character Actor skill forces another class choice, and Mordecai recommends Football Hooligan. She gains ten Constitution and the Mascot skill, which gives the party temporary Dexterity and Constitution bonuses when Mongo damages enemies. Mordecai also identifies a useful quirk of Character Actor: if Donut trains a temporary class skill or spell enough to gain a level, she appears able to retain the earned portion after changing classes on the next floor.

Katia's Pathfinder skill shows the twenty-car train and its unusual cars while the party scouts forward. At Sirin Station 81, hundreds of level-six Dreks swarm aboard. The group retreats into car 15, a Janitor's Lair, where they kill two level-seventeen Jikininki. Carl places an alarm module and a wall-mounted spike module to warn and slow anything approaching from the front.

At Mora Station 82, additional monsters board, including large Psycho Stickers, and a Drek bites Carl's foot after he realizes his usual pedicure-kit protection has expired. When the forward alarm is triggered, Carl exploits an unusual property of Protective Shell: the barrier remains fixed in place while the train continues moving. The moving cars carry the mobs into the stationary barrier, smashing and sweeping them through the train. Carl, Donut, Katia, and Mongo then run back toward car 20, closing doors behind them. The chapter ends with the party still aboard the train and several minutes away from transfer station 83.

The party disembarks safely at transfer station 83, where Carl's Escape Plan skill reveals more of the Red Line map. Trains run upward through stations 11 to 435, saferooms appear at transfer stations, and stairwells appear at stations 12, 24, 36, 48, and 72 on each colored line. Upstairs they meet Limp Richard, a Mole Man shopkeeper, and Wendita, the Bopca Protector running the Nirula's saferoom. Mordecai transfers in as a level-50 Grulke Infantry and reports that only 389,441 crawlers remain. He notes that the third floor normally leaves far more survivors and lasts twice as long, so the AI may compensate with better rewards after Borant's veto.

Donut uses her Negotiation skill against Wendita's 50,000-gold price for a personal space, while Carl opens loot from the previous floor. A court-overruled achievement produces a Platinum compensation box whose coupons include a free level-three personal space, environmental upgrades, crafting tables, and table upgrades. Carl also receives the Enchanted Necklace of the Haute Bourgeoisie, which carries the Skyfowl settlement gem, adds Dexterity and Talon Strike, and pays periodic taxes. He learns the Bang Bro spell. Donut receives the Tiara of Mana Genita and reads the mailed Hole spell, while Katia receives a bracer that can become a Shatter-enchanted shield and can be incorporated into her doppelganger form.

Carl spends his twenty-four stat points on Strength, Constitution, and Intelligence. Mordecai then has Carl, Donut, and Katia redeem their three level-three personal-space coupons and conjoin the spaces, producing a shared level-five space while all three remain joined. They add major upgrades including an ultra-stabilized bed, an automatic shower, an Enhanced Crafting Studio, and a Training Room. The bed reduces full rest to two hours and grants a Good Rest bonus; the shower improves stats and lowers Detectability.

After the coupons and 15,000 gold are paid, a new doorway opens to the Conjoined Personal Space of Team The Royal Court of Princess Donut. The chapter ends as Donut discovers that the space can be renamed and leads Mongo inside to inspect their new home.

The new communal space takes shape as Donut places the shared rooms, Carl applies the Enhanced Crafting Studio, Katia's Training Room appears, and Mordecai gains access to his own manager quarters because the conjoined base has reached level five. Mordecai explains how personal spaces and shared upgrades work, including the risk that Katia would take her space and its attached upgrades with her if she left the party. Exhausted, Carl sleeps in Donut's room with Donut and Mongo. The Ultra-Stabilized Bed gives him a full rest in about two hours and unlocks a thirty-hour Good Rest bonus that increases base stats, experience gain, and skill training.

During breakfast and the recap show, Mordecai starts imposing a daily schedule of buffs, training, crafting, and exploration. Information from other crawlers shows that identical station numbers can exist on different combinations of lines, reinforcing the need to map the Iron Tangle collectively. The recap identifies the current top ten, including Carl at sixth and Donut at seventh.

The daily announcement adds a critical fourth-floor rule: stairwells will not open until six hours before floor collapse, so no crawler can descend early. It also confirms that killing a top-ten crawler awards the listed bounty, while a listed crawler who survives the floor receives ten percent of their own bounty. The system acknowledges the unusually high third-floor mortality but tells the surviving crawlers it will not reduce the danger.

Carl then discovers a delayed message in a folder for deceased crawlers. Brandon died on the third floor while holding off Shade Gremlins so Imani, Elle, and others could escape. His last message asks Carl to find Chris, apologize on Brandon's behalf, tell Chris that Brandon said he was right, and most importantly tell him that Brandon loved him. The loss hits Carl hard. Ignoring Mordecai's planned training order, Carl enters the Training Room, selects Bare Knuckles, and attacks the practice dummies.

After training, Carl begins setting up the Enhanced Crafting Studio with his alchemy, sapper, and engineering tables. He experiments with the Goo-inator 3000 on a massive iron breastplate and earns his first crafting achievement, which gives him a Bronze Crafter's Box containing ordinary tools and a bucket of pink glitter. Mordecai stays behind to study changes to the crafting system while Carl reports route information from Bautista, whose group is at station 199 on the Azure and Brown lines.

After showering and restoring Carl's foot buffs, the party visits Limp Richard. Donut negotiates down the price of a padded mallet, while Carl examines but does not buy a 75,000-gold Battery Fabricator. Carl also trades five Louis L'Amour books for five of Limp Richard's science-fiction books, recognizing that books are unusually valuable entertainment to isolated shopkeepers.

The group next studies the Nightmare Express map rather than boarding immediately. The express follows a five-stop figure-eight route linking multiple transfer stations and a non-transfer stop at station 436, showing that the same station numbers can occur at different places in the Tangle. On the Yellow Line, the party discovers that monsters aboard a stopped train cannot attack crawlers standing on the safe platform. Through Katia, Hekla reports that her group has been exploiting the same effect and that monsters appear to leave trains every five stations and move through connected cave systems. Carl treats platform sniping as a possible time trap rather than a useful long-term strategy.

After about an hour of low-yield platform kills, Carl, Donut, Katia, and Mongo board a Yellow Line train near its sealed engine car. The engine door requires a Yellow Line Engineer's Key. When Cave Mudge Bonkers enter from the next car, the party uses a practiced close-quarters formation: Mongo and Katia hold the sides, Carl controls the center, and Donut attacks from Carl's shoulder. Katia uses her reshaping ability and shield integration defensively, and Carl tests Talon Strike. They kill the first wave, but four more Bonkers charge in as the chapter ends.

Carl tests the train defenses he built from reshaped armor, using a heavy Gangway Chock and improvised exterior-door braces to isolate a car. At Phantom Kangaroo Station 84, Pollyslogs try to board and are caught by the closing doors, confirming that the barricades can buy time but are not yet well fitted. The party then explores car 5, an employee break room, and meets Vernon, the Yellow Line conductor.

Vernon explains that the colored-line train runs from station 11 to station 435, after which his memory becomes fuzzy and he finds himself back at the yard at station 10. He retains injuries, hunger, and objects he has taken from the train, while original objects reset to their starting places. He demonstrates the effect with duplicate drawings of his supposed wife and repeatedly restored gold coins. New janitor ghouls join each run, and the engineer may change. Vernon also says a monster that once stayed aboard past station 435 was reduced to a repeatedly killed skeleton, and that the only circumstance he has heard of that caused an engineer to leave the sealed engine car was a derailment. The full trip from station 11 to 435 takes about three days.

Carl and Donut later inspect car 10 and discover the Yellow Line Reward Room. The porter, Pierre, lets each crawler choose one suitcase number from 1 to 200 for that line. Carl's case contains ordinary luggage plus useful potions, including an Invisibility Potion. Donut's case triggers Carl's Find Traps skill only after he begins opening it. Literal Fire Ants pour out, ignite the employee car, and set off bottles of moonshine.

Carl, Donut, Katia, and Mongo flee onto the platform at Banshee Station 116 just before the train departs. Vernon is engulfed by the fire ants and does not escape. The burning train pulls away with the ants overwhelming the monsters aboard, and the chapter ends with Donut calling it the worst prize ever.

Already stranded at Banshee Station 116 after the fire-ant disaster, Carl, Donut, Katia, and Mongo retreat into the cave system behind the platform. The station is populated by Red Cornets, skinless rabbit-like monsters whose sonic attack inflicts the Queasy debuff. During the initial approach, Zev privately tells Carl and Donut that viewers find Katia boring and urges them either to make her more interesting or remove her from the team. Carl rejects treating Katia as entertainment, while Donut immediately tries to coach Katia on appearance and branding.

The party deliberately fights small groups of Cornets until Carl, Donut, and Katia develop resistance to the sonic nausea. They notice that the Cornets carry used vials containing traces of an unknown golden substance. Near a sealed concrete room, Carl's Escape Plan skill reveals a blue control sigil that only he can see. Mordecai identifies it as a showrunner-controlled gating sigil, but neither he nor Carl knows what it gates here. Inside are two sleeping Dwarven Industrial Light-Duty Automatons and a materials cart. Katia reports that Hekla and Eva found a similar room elsewhere, but the relationship between the robots, sigils, and Cornets remains unresolved.

After clearing the Cornets, Carl observes many discarded vials and infers that the creatures may be traveling to every fifth stop to obtain the substance and somehow return, but this remains his hypothesis. The party destroys the two inactive automatons for crafting material, yielding roughly fifteen tons of collected scrap and damaged dwarven batteries.

Bautista then tells Carl that Imani is alive and wants to speak with him about Brandon and Chris. He also shares a navigation rule he has learned: transfer stations ending in 1 contain a Desperado Club, while those ending in 9 contain Club Vanquisher. Carl chooses station 131 as their next destination so he can try to meet Imani, gather more route information, and open the coming fan boxes. The chapter ends with the plan to board a train for 131, before the party actually departs Banshee Station.

Carl, Donut, Katia, and Mongo reach transfer station 131 after collecting the Yellow Line station list. During the trip Mongo reaches level 15, his full physical size, and gains Earthquake, a leap-attack ability with a chance to knock enemies down. At the station, the party returns to their personal space before the recap and Desperado Club visit. Mordecai has spent Donut's table-upgrade coupons to raise the alchemy table to level three and begins turning their accumulated ingredients into more useful supplies.

Mordecai produces two doses of his Special Brew, which continuously heals and regenerates the drinker for thirty seconds but causes a long potion-sickness period and only works twice per crawler. Donut drinks two Superb Constitution Buff Potions for a permanent net gain of four Constitution. Mordecai also makes Fragmenting Potion Balls that can be filled with potions and thrown at enemies. Carl's improved Determine Value skill confirms that the stuffed Kimaris figure is his only Unique item, while Carl's Doomsday Scenario is merely listed as Pretty Damn Rare.

Donut's Platinum fan box contains an Enchanted Mongoliensis Saddle. While Donut rides it, her offensive spell damage increases and Mongo gains Constitution and melee bonuses. Carl's Platinum fan box instead summons the Prize Carousel, hosted by Chaco, a former crawler champion now serving as an NPC host. Mordecai immediately attacks Chaco inside the protected personal space and is removed for a seven-day rules violation. Chaco gives only a limited explanation: he says the old incident was hundreds of cycles ago, that he acted on Mordecai's manager's orders, and that refusing would have led to Mordecai's death and the loss of Odette. The chapter does not resolve the history further.

Carl must choose among nine obscured prizes. Personal items from his old life, including his father's motorcycle and Carl's old tool chest, are used to pressure the choice. He selects an apparently ordinary book marked with an anarchy symbol. The item is identified as the unique Dungeon Anarchist's Cookbook. When Carl opens it, Escape Plan reveals hidden text beginning with a message that the book has found him for a purpose and that together they will burn the dungeon system down.

Carl privately reads the hidden text of The Dungeon Anarchist's Cookbook. The book says the 24th edition descends from a copy first awarded to Porthus the Rogue in the fifteenth season and passes from crawler to crawler when specific conditions are met. Its real contents are invisible to viewers and showrunners but visible to the current System AI. Carl receives a second scratchpad page for material that will become part of the 25th edition. The central restriction is absolute: if Carl tells anyone about the hidden contents, or the season's operators realize what the book really is, the hidden information will erase and he will permanently lose access. He therefore reads alone and must disguise any use of its knowledge as his own discovery.

Without Mordecai, Carl decides the team must rely more heavily on shared information from other crawlers. The system also announces that sponsorship bidding will soon end and that a sponsor tab will appear. Katia cannot enter the Desperado Club because she lacks a pass, so Carl and Donut go without her and pay for bounty-related security. Clarabelle confirms only that Mordecai has spoken bitterly about Chaco before; she does not explain their past.

Inside, Carl and Donut meet Elle, now a Frost Maiden, and later Imani, now an Obsidian Butterfly and Fire Spiritualist. Elle says twenty members of their broader group remain, while Imani is the only surviving member of the younger group. Imani explains that Chris changed after choosing an igneous rock race, became increasingly focused on hunting, argued with Brandon, and left with several others. Chris is still alive, has stopped answering their messages, and had been trying to find Carl. Imani gives Carl this context because Brandon's final message did not explain the split.

As Carl begins showing Imani and Elle Mordecai's rail map, a commotion erupts on the dance floor. Donut's Cockroach skill has activated and her health is deep in the red. A human crawler lies dying from a slashed throat, and when he dies a skull appears beside Donut's name, marking a crawler kill. The chapter ends at that moment without establishing in this unit who initiated the confrontation or why.

The club attack becomes clear immediately after Ji-Hoon's death. An unnamed woman had cast a spell that stunned Donut's hired guards, and Ji-Hoon then stabbed Donut in the back with an enchanted dagger that deals double damage on a backstab. Donut's Cockroach skill prevented the otherwise fatal blow, and she killed Ji-Hoon while defending herself. The woman prepares another attack, but Elle kills her with an icicle. Donut is shaken by having killed a real crawler, and Carl reassures her that she survived an attempted murder rather than initiating the violence.

Astrid, the level-125 Bloodlust Sprite who serves as assistant manager of the Desperado Club, apologizes for the failure of the paid security. She offers Carl and Donut a refund and complimentary security on later visits. Carl asks her not to punish Bomo and The Sledge too harshly and requests the same two guards for future visits, which Astrid allows. Donut later loots Ji-Hoon's armor and enchanted daggers for possible use by Katia.

Carl, Donut, Imani, and Elle compare rail information. Elle points out that all known transfer-station numbers are prime numbers. Imani argues that they still need evidence from the every-fifth-station caverns and from the end of a colored line. Carl assigns Imani and Elle to investigate a fifth-station area while he plans to force an engineer out of a sealed engine car, using Vernon's statement that derailment can do so.

At the Desperado Club casino, Igor explains that the lower Larracos area is connected to the faction armies that will fight on the ninth floor. Carl uses his 100,000-gold comp chip on the Wheel of Fortune after learning the high bet removes most negative outcomes. He wins a Scroll of Upgrade. The scroll upgrades his Enchanted Toe Ring of the Splatter Skunk from +3 to +10 Strength and raises its Powerful Strike bonus to +5. Carl refuses another wager and ends the chapter planning an hour of training, more crafting, and a deliberate train crash.

Back at the communal base, Carl and Donut initially mistake Katia for Hekla. Katia explains that her Walk in Their Shoes ability can change the displayed name only after she reproduces a target's appearance with at least 90 percent accuracy; her current Hekla imitation is only 65 percent. She has spent her upgrade coupons on a level-three Makeup Table, which lets her superimpose faces she has seen and save three designs. She then returns to her own form. Carl gives her Ji-Hoon's armor, adding both useful stats and more material for her doppelganger body.

Carl trains Bare Knuckles to level nine, while Donut raises Dodge to level seven. During crafting, Carl secretly consults the Cookbook in the restroom and experiments with bomb deconstruction. Donut practices riding Mongo's saddle, discovering that a temporary magical strap anchors her but does not prevent Mongo from bucking her off.

The party moves to an Ochre Line platform to prepare Carl's plan for forcing an engineer out of the sealed engine car. Carl verifies the third rail is live with wired hob-lobber fuses and one of Donut's clockwork Mongo duplicates. He also paints an X on the departing train so allied crawlers will know it is the last train expected before the disruption.

Using an idea from the Cookbook but altering the design so his work appears independent, Carl builds two contact-triggered Jelly Bomb landmines and places them on the track. His goal is to derail the next train without killing the engineer. Nearby is a Club Vanquisher entrance, confirming another station type. Elle also reports that her group explored one of the every-fifth-station areas, fought three neighborhood bosses, and found a borough boss identified as a Krakaren. The chapter ends with the two mines armed and the next train approaching; the derailment has not happened yet.

Carl's two Jelly Bombs derail the next Ochre Line train at station 149. The engine car remains intact, and the crash forces its engineer, Gore-Gore, a level-40 ManTauR, to climb out. Gore-Gore initially mistakes Carl, Donut, and Katia for stranded passengers. Before another train crashes into the wreckage, he confirms that the line's employee return process and engineer return process are different.

At station 435, conductors and porters leave the train and pass through a Kravyad-controlled employee route whose portal causes their memory loss. Gore-Gore instead keeps driving the engine car alone through an abyss gate just beyond station 435. The gate teleports the intact engine car to the depot without erasing his memory, after which he sleeps and waits roughly nine or ten hours for the next set of passenger cars. Gore-Gore says passengers in the ordinary cars can be killed by the deep-cleaning reset, while someone inside the engine car would survive the abyss gate. However, engineers are forbidden to admit anyone into the engine car and do not voluntarily leave an intact one.

The party realizes an engineer's color-coded key could let them enter another engine car on the same line if they can get ahead of the crash-induced traffic jam. Donut proposes using one of the fast named trains to jump ahead. Before they can act, Gore-Gore emerges from Club Vanquisher enraged, apparently having learned that they caused the derailment. The dungeon identifies him as a neighborhood boss and an adherent of Grull.

Gore-Gore resists Donut's Magic Missiles and badly injures Mongo, Katia, and Carl. Each successful punch with Carl's gauntlet increases a displayed cumulative chance of summoning Grull, eventually reaching 10.5 percent and triggering a ten-second countdown. Carl uses Protective Shell to break Gore-Gore's grip, then activates Talon Strike and drop-kicks him onto the electrified third rail before the god can appear. Gore-Gore dies from the current, while Carl is also shocked and pulled to safety by Donut. The chapter ends with Carl receiving notice that the Valtay Corporation has become his first sponsor, without yet explaining the sponsor's implications.

After Gore-Gore's death, Donut reaches level 28 and learns that Princess D'nadia of the Prism Kingdom is her sponsor. Carl tells Donut privately that his sponsor, the Valtay Corporation, is hostile to Borant and had helped trigger the accelerated season, making him wary of becoming a pawn in their conflict. Gore-Gore's corpse yields an Ochre Line Engineer's Key, Rev-Up Magic Hair Restoration, and an unusually broad neighborhood map that reveals the entire Ochre Line, all current trains, and the sharply increasing distances between later stations. Because the derailment has stopped traffic, monsters farther up the line begin walking the tracks toward their every-fifth-station destinations.

Katia reveals that Gore-Gore actually severed part of her flesh along with her integrated armor. Healing restored her health but not the missing tissue; she can reshape replacement fingers from the rest of her body, yet the loss leaves her feeling as though she is gradually losing herself. Katia has also been sponsored, by Princess Formidable of the Skull Empire. Using the expanding route map, she identifies a fast path through the Dismemberment Limited and then the Nightmare Express that could reach the far end of the system in hours rather than days.

Imani and Elle supply the missing evidence from an every-fifth-station cavern. Each monster line receives a race-specific Rev-Up Vitamin Shot from a Pooka neighborhood boss, then enters a one-way portal back to its home station. The drug is addictive and the monsters physically change if they miss a dose. A Krakaren borough boss appears to manufacture the different drugs. This confirms the broad drug-loop mechanism Carl had only hypothesized earlier and explains why widespread train stoppages can create cascading problems.

Carl, Donut, Katia, and Mongo board the Dismemberment Limited, a small maglev train operated by Levi the Seventh, a Troll Flesher and Hobgoblin Skellie Symbiote. Boarding triggers a quest to keep Levi from being devoured by the Fleshers in the rear cars; failure would turn every crawler aboard into a Flesher. Carl and Katia brace a heavy metal plate across the connecting door while hundreds of Fleshers and the war mage Dismember attack from the other side.

Dismember begins charging a larger spell and taunts the group through the barrier. Carl orders an unpracticed maneuver, Surprise Three. Donut opens a Hole through the metal plate, Carl grabs Dismember by the hair and pulls his head through, and Donut closes the Hole. The chapter ends as Dismember's severed head drops to the floor.

At Mauve Line station 281, Carl, Donut, and Katia leave the Dismemberment Limited after holding off Dismember's bereft Fleshers. Zev schedules Carl and Donut for a Planet Beautiful segment about Earth beauty pageants and pet shows. The party decides to wait for Protective Shell to recharge before attempting the Nightmare Express.

Carl buys an Armorer's Table and spends his upgrade coupons to raise the Sapper's Table to level three. The Armorer's Table lets him convert shaped scrap into system-recognized equippable armor, which is important because Katia can incorporate only properly equipped items into her doppelganger mass. In private, Carl also studies Cookbook notes explaining that an equipped backpack can affect how contained material behaves. He disguises that source by presenting the backpack idea as something he noticed in the armorer menu.

Carl builds Katia a reinforced backpack and loads it with more than a ton of dense metal pieces. Once Katia equips the backpack, its contents become part of her available transformation mass. She initially collapses under the unfamiliar weight, then reshapes into increasingly large armored forms. She can unequip the backpack to shed the extra mass and vary how much metal she deploys, though equipping it still takes time and the added weight reduces Dexterity. The experiment gives the party a practical way to turn Katia into a much heavier tank while keeping the Cookbook secret.

The recap shows war mages on multiple named trains, Quan Ch destroying a train with a powerful flying jacket, and Lucia Mar already near stairwells. The system reiterates that stairwells remain closed until six hours before collapse and reports that broken trains are causing premature route chaos. Carl then receives a Bronze Benefactor Box from the Valtay Corporation containing Neural Enhancer #544. After installing it, he gains Identify and Analyze Subspace Portals. He can now inspect compatible portals, determine properties such as whether they are two-way and gated, and request a visual image of the destination. The chapter ends when Carl tests the upgrade on the personal-space doorway and sees the coffee shop on the other side.

At station 283, the party waits for the Nightmare Express while Donut trains Hole to level three. During a short Desperado Club visit, Donut raises Dodge through its guild and Carl adds more than twenty crawlers to his chat network, encouraging them to exchange route information. The new network quickly produces useful but noisy intelligence about the distinction between one-way colored subway lines and looping named trains.

When the Nightmare Express arrives, Carl discovers that passengers may enter only through the rear caboose. Reaching the front would require crawling across the roofs of dozens of cars, including open livestock cars full of giant monsters, while the train moves through a tight tunnel. He refuses that route and devises a different plan for the train's next pass.

Carl and Donut run into the tunnel ahead of the approaching Nightmare Express. Donut prepares Puddle Jumper while Carl activates Protective Shell at the last moment. They teleport several hundred feet down the track, leaving the stationary shell behind so the moving train carries its red-tagged occupants through the barrier. The attack kills the engineers and monsters and badly damages the rear cars, but it also leaves the unmanned steam train accelerating out of control. Donut reaches the platform; Carl does not. The cowcatcher strikes him, and his enhanced Constitution, healing, and invulnerable foot barely keep him alive as he is thrown onto the front of the locomotive.

Carl climbs into the engine cab and discovers the boiler is rapidly becoming a train-sized bomb. Fire Brandy, the Nightmare Express firewoman, emerges from the boiler and teaches him how to vent pressure, brake, and operate the locomotive. She also explains the track-switch control that can route the train to Station Repair. Carl finds Sheol Bricks used as boiler fuel and a Steam Engineer's Key that works on all 400 steam-type trains in the Tangle.

Taking control of the Nightmare Express raises Carl to level 32, and the Protective Shell attack is credited with killing three neighborhood bosses at once, earning a Platinum Big Daddy Box. The ruined livestock cars remain attached behind him. Carl asks Donut to search the track for a neighborhood map so he can orient himself and plans to inspect station 436 before looping back for the others. The chapter ends with Donut warning him never to put her through that kind of scare again.

Carl drives the captured Nightmare Express through a switching cavern containing Auxiliary Tracks, Station Repair, and Recycle routes, then stops at Abyss Station 436. After nearly an hour climbing a central stairway, he reaches the Abyss, an enormous burning pit ringed with industrial subspace portals. Passenger cars from colored lines emerge driverless from the portals and fall into the wreckage below, where Jikininki swarm them. The absence of engine cars confirms that the ordinary cars are discarded while the engines alone are returned to the depot; the passenger trains are being rebuilt rather than literally looping intact through time.

Carl analyzes one of the Ultima Corp DungeonWerx portals with his Valtay neural enhancer. It is a one-way portal gated by conveyance type and compatible keys. A visual analysis shows a huge fenced trainyard containing engine cars and large numbers of zombie-like creatures, with dwarves outside the fence and a smaller portal visible in the yard. The system marks three of Carl's items as compatible with the gate: the Ochre Line Engineer's Key, the Steam Engineer's Key, and the souvenir conductor hat issued when the floor began. Carl therefore infers that the overlooked hat can satisfy the portal's key requirement, although he has not yet tested a crawler transit through the gate.

Carl broadcasts what the group currently knows, carefully separating established information from uncertain routes. He describes four possible ways back toward the early stairwell stations: ride a colored line to its end while holding the hat and risk arriving exposed in the zombie-filled trainyard; use an engineer's key to arrive inside an engine car; try the Kravyad-controlled employee portal at station 435 despite its memory and time effects; or control a named train through station 436 and use the switching system. He also relays a rumor about a hidden backward-running train, but does not treat it as confirmed.

When Carl returns to station 283, Donut has reached level 30 and 100 Charisma. Princess D'nadia's benefactor box gives her the unique Prism Industries Capacitating and Focusing Goggles, which protect and enhance her vision and can focus ocular-origin energy spells, allowing new multi-target and stored-energy uses of Magic Missile. Donut also explains her new Love Vampire ability: she can designate one enemy at or below her level to take damage intended for her until that target dies, with a cooldown of roughly two hours.

Meanwhile, Elle and Imani report that widespread train destruction has stranded their group and forced them toward the drug-return portal and a long hike. Carl's own boss rewards include a +3 Dexterity upgrade to his Trollskin Shirt and five applications of Seize the Day Toothpaste, which provide thirty hours of triple damage against ordinary bosses or quadruple damage against Province, Country, or Floor Bosses when applied in a saferoom. As reports of disabled lines multiply, a passage by tenth-edition Cookbook holder York reinforces Carl's sense that isolated crawlers still form a kind of collective. The chapter ends with Carl convinced that more must be done for people trapped on the tracks, but with no solution yet.

After resting, Carl receives an update from Elle and Imani: when withdrawal begins, the dormant automatons in the repeated robot rooms awaken and a previously sealed passage opens into a long descending tunnel, apparently toward another rail line. Donut also discovers that her temporary Intelligence buffs raise her effective spell points enough to read the Minion Army tome she has carried since the first floor. At level one, the spell requires five minutes of immobile casting, has a five-hour cooldown, and gives intelligent enemies in a thirty-meter area only a two-percent chance to switch sides, so Carl warns her not to use it casually.

The team then finds the transfer station overrun by Babababoons suffering stage-two withdrawal. Their Strength is doubled, they have lost reason and speech, and they attack anything not suffering the same condition. This confirms that transit stations cease to be safe from ordinary floor mobs once withdrawal advances. Carl, Donut, Katia, and Mongo clear the station. Katia experiments with shifting her internal metal to absorb attacks and begins developing moving defensive spikes, while Carl tests his new Banger Sphere ammunition and Donut finds mounted combat on Mongo still impractical.

Reports from Carl's crawler network show the same stage-two withdrawal outbreaks spreading across the rail system. The party boards the Nightmare Express and returns to the switching cavern. Carl stops before the Station Repair gate and analyzes it directly. Unlike the Abyss portals, this gate is a pass-through, two-way portal, still gated by conveyance type and compatible keys. He sees a steam train emerge from it and switch automatically onto another route, demonstrating that the track network on the far side actively controls outbound routing. The Auxiliary Tracks can bypass the portal but would leave the Nightmare on whatever route the previous train used; Recycle clearly leads to the Abyss.

A visual analysis of the Station Repair portal again shows the zombie-filled trainyard. Fire Brandy speaks with Donut and Katia while Carl returns to the cab. Donut identifies herself as Mongo's mother, and Katia says she had been about to adopt before Earth was destroyed. Carl tells Fire Brandy they are taking the train through Station Repair and asks whether they will be allowed to drive it back out. She does not know. The chapter ends with Carl preparing to enter the two-way portal, not yet knowing whether the trainyard will permit their return.

The Nightmare Express passes through Station Repair intact and enters Station and Repair Hub E, one of what Carl infers must be multiple enormous trainyards serving the floor. Thousands of apparently zombie-like creatures crowd the fenced yard, but closer inspection identifies them as Festering Ghouls created when victims die during stage-one withdrawal. They are not undead and cannot be countered with anti-undead effects. Their description says they are driven to consume organic material and gather with more of their kind for an unspecified purpose.

The train is automatically routed into service bay 32, where Widget, a Grease Gremlin technician, arrives from a control tower. Widget says the yard is being abandoned because the ghoul population is nearing critical mass. More importantly, he tells Carl there is a much simpler intended route to the stairwells: the named Escape Velocity train connects with the early stairwell stations, including a route from station 89. He also explains that the withdrawal-disposal system is malfunctioning. Ghouls are supposed to enter rolling cages, ride a service conveyor back to a yard, and then be transferred onto Terminus-direct trains for disposal in the Abyss, but the combined system has broken down.

After the yard's outer wall collapses, Widget changes the plan and offers to use the turntable to place the Nightmare on the employee line, which has service entrances at the low-numbered stations. Before he can finish, a ghoul Donut had apparently killed reanimates, tears off Widget's head, and kills him. Donut therefore climbs the chain to the control tower herself. After several mistakes she aligns the turntable, opens the yard gate, and lets Carl separate the engine from its ruined cars and drive toward the employee line.

Outside the yard, the party rescues Madison, a human NPC who works in Iron Tangle human resources. Her confident memories of Yard A and an executive apartment quickly prove inconsistent with her actual knowledge, reinforcing Carl's growing understanding that many NPC backstories were implanted without corresponding places or histories. Using a Cookbook essay about deliberately challenging NPC assumptions, Carl presses her for operational information.

Madison reveals that she manages benefits for the Kravyad and for six Station Mimics. She identifies Terminus as the Station Mimic system and says the mimics become ravenous when too few passengers are sent into them. This means station 433, where workers tell passengers to disembark, is itself a trap. The chapter ends with Carl immediately warning Bautista not to leave his train at Terminus Station.

Bautista replies that Carl's warning came too late. Roughly four hundred crawlers had gathered on his train, and Terminus Station swallowed the first group that climbed upstairs. The station is a city boss whose tongue and spawned mouth-creatures are attacking the survivors while they wait for another train. Carl tells Bautista that station 435's employee portal may be their remaining route and immediately questions Madison about the Kravyad.

Madison explains that the Kravyad are blue, six-armed, naga-like human-resources workers rather than designated combatants. They hypnotize conductors and porters at the end of a shift, hold them in a stupor for eight to twelve hours, and send them through the employee portal near the next shift. The portal is lifebound to the local Kravyad, so killing the Kravyad closes it. Madison also admits that troublesome employees are deliberately marked with gold armbands so the Kravyad know they may eat them. Carl passes the operational information to Bautista without claiming he can solve the situation for him.

Elle and Imani independently confirm the withdrawal-disposal machinery. Once ghouls enter the repeated robot rooms, the automatons lock them in rolling carts and push the carts down a long service conveyor toward the trainyards. They also report occasional Wrath Ghouls, which may be a later withdrawal outcome, but that relationship is not yet established. At stairwell station 24, Carl and Katia find five closed stairwells and ten connected train platforms, one labeled Escape Velocity III, confirming Widget's route information. Festering Ghouls are already moving through the station, but why they are unaffected by the third rail remains uncertain.

While alone with Carl, Katia reveals a third-eye experiment and then shows him a PVP Coupon she secretly recovered after seeing Donut hide it under the tracks. The coupon rewards Donut for killing Carl. Katia says Donut received one coupon for each party member but discarded only Carl's where Katia could observe, leaving Katia afraid Donut may still possess hers. Imani confirms that the first member of a party to earn a player-killer skull receives a Savage box containing coupons for every party member. She also says Donut discussed both coupons with her and that she advised Donut to get rid of them. The source does not establish what Donut ultimately did with Katia's coupon. Carl decides to ask Donut privately rather than let the uncertainty widen the split.

Stations 36 and 48 match station 24, while other low-numbered stops reveal that the employee-side network does not mirror the ordinary upper routes. Station 60, supposedly a large employee residential district, is only a decrepit, empty interchange. Madison's claimed home, the workers' families, and the promised settlement appear never to have existed outside implanted memories. Madison refuses to leave and waits there for her ex-husband Rod. Carl abandons her. The chapter ends when Donut finally identifies why Madison felt familiar: she reminds Donut of Bea's mother, whom Donut remembers as cruel to her cats.

With four days and twenty hours remaining, Carl turns the Nightmare Express around and parks near station 41 so the party can rest, train, visit the Desperado Club, and delay their Planet Beautiful appearance. Imani reports that the Meadow Lark survivors rode the ghoul conveyor to breached Trainyard D and fought their way into the administrative building. Bautista reports a different crisis at station 435: his group neutralized the Kravyad's hypnosis, but the NPC is threatening suicide, which would close the lifebound employee portal. Many of the stranded crawlers no longer possess their souvenir hats.

At the Desperado Club, Carl expands his chat network and unexpectedly finds Frank Q. alone, drunk, level 17, missing a hand, and separated from Maggie since the end of the second floor. Frank says Maggie is still alive but no longer speaks to him. He gives Carl the Enchanted Night Wyrm's Ring of Divine Suffering as a form of revenge. The ring grants +5 percent to all stats and the Marked for Death skill. On the fourth floor, a user can mark one full-health crawler after a thirty-second formation period, with a five-hour cooldown. When the marked crawler dies, the ring permanently increases the wearer's stat matching the victim's highest stat; the reward grows after every three marked kills. The cost is severe: while a mark is active, the wearer cannot heal until the target dies.

Frank then explains why the ring destroyed his family. He received it upon entering the dungeon and later forced Yvette to wear it so she could gain stats without directly fighting. Before Frank and Maggie attacked Carl and Donut, Yvette marked Carl. When Carl's dynamite badly injured her, the active mark meant she could not heal while Carl remained alive. Maggie therefore strangled Yvette, ending her otherwise unrelenting pain. Frank recognizes that Yvette never shared her parents' violence, while Carl concludes that their choices created the tragedy.

Frank also says Maggie retained the legendary potion from the Maestro encounter that can maximize Find Crawler, although he does not know whether she has consumed it. Carl accepts and equips the ring for its stat bonus but resolves not to use Marked for Death. Donut returns from the club and they leave. Carl tells Frank that Yvette did not deserve to die; Frank watches him put the ring on and says, "Vengeance is mine."

Carl and Donut are teleported to a deluxe production trailer located underwater. Because the trailer remains below sea level inside Borant's main planetary system zone, Carl retains access to his dungeon interface and inventory. The trailer AI, Mexx-6000, explains that Borant is using a cheap dual-layer planetary-zone architecture without the usual administrative bubble, meaning Carl still falls under the dungeon AI's rules while in the trailer.

During the Planet Beautiful recording, Carl refuses to narrate a script that presents misogynistic internet stereotypes as factual explanations of human beauty pageants. The gray producer Bin admits the program's sudden popularity has brought corporate pressure, that the production used a discounted AI consultant whose Earth scan was incomplete because Borant began the season early, and that he is losing control of the show he created. Carl agrees to narrate a different segment about video games. Donut, meanwhile, enthusiastically goes off script during her pet-show segment.

After recording, The Sledge tells Donut that Frank has been killed inside the Desperado Club by Chris, Brandon's brother, who then walked out and was banned from the club. Carl does not yet know why Chris killed Frank and sends Imani and Elle a message asking whether Chris has contacted them. The motive remains unresolved at this chapter boundary.

Before leaving the private trailer, Carl asks Donut directly about the PVP coupons. Donut says she buried Carl's coupon under the train track and threw Katia's coupon into the trash at the Hotdog on a Stick saferoom. This resolves the uncertainty from Katia's observation: Donut discarded both coupons rather than retaining Katia's. Carl also takes several self-powered cooling shelves and a makeup table from the trailer, privately thinking of Cookbook recipes that require cold preparation while concealing that source from Donut.

Bautista then reports that his group accidentally killed the Kravyad while trying to paralyze her, closing the employee portal. More than 150 stranded crawlers lack souvenir hats, all nearby trains have stopped, and the group plans to walk roughly fifty kilometers toward the Abyss. Carl suggests sending hat-holders through first and looking for a route from the Abyss catwalk to station 436 and a controllable named train, but this remains an emergency plan rather than a proven rescue.

As Carl and Donut prepare to return, Carl analyzes the one-way portal back to their personal space. A fresh visual image shows that the room, empty moments earlier, now contains at least thirty women of many races. Hekla is among them, with Katia showing her something near the training room. The chapter ends on Carl's surprise before the reason for the gathering is established.

Hekla and roughly thirty members of Brynhild's Daughters are waiting inside the Royal Palace when Carl and Donut return. Katia explains that, because her personal space is conjoined with theirs, she can whitelist visitors. Hekla says her team reached the low-numbered network through a Kravyad portal and discovered that station 60 contains a selector connecting the twelve Homeward Bound platforms, making it possible to move between the employee tracks associated with different trainyards.

Carl meets Eva Sigrid in person, a level-27 Half-Nagini, Half-Orc Nimblefoot Enforcer and Katia's pre-dungeon friend. Eva carries thirteen player-kill skulls, while Hekla carries none, increasing Carl's suspicion that Eva may handle violence for the group. Hekla asks the Royal Court to help rescue at least a thousand crawlers trapped at station 101 on the Vermillion line, including Li Jun and people in Carl's chat network. Multiple lines serving the station have failed, mobs are converging, and the trapped crawlers cannot simply hike the long distance to a stairwell while fighting continuously.

The Daughters have already captured an unused Vermillion Terminus-direct train and attached a second engine at the rear so the train can return in reverse. The line remains powered and largely free of wreckage, but a huge ghoul horde blocks the route. Hekla needs a stronger front-end solution than the subway's small debris guard. The proposed solution is Katia herself, reshaped into an armored cowcatcher and scoop.

Carl initially assumes Hekla is treating Katia as disposable, but Katia privately tells him the idea is hers. She altered the backpack to carry more metal and rubber and wants to use the role she has been training for. She also explains why the Daughters' return matters so much to her: Hekla brought the whole team back to collect her. Carl tells Katia she is not disposable, apologizes for not making her feel fully welcome, and offers her the option of staying with him and Donut. Katia chooses the rescue plan but remains in Carl's party until it is finished.

The group rides the Nightmare toward station 60. Katia reveals that Eva was an economics professor she knew in Reykjavik and that Hekla knew Eva before Katia did because Hekla was Eva's psychiatrist. At station 60, Carl and Donut stop beside Tizquick, a grieving conductor whose implanted memories of a daughter have collapsed with the false employee settlement. Carl tells him that his pain will matter someday. The chapter ends with Hekla pressing the group to hurry because the main ghoul horde is approaching station 101 and crawlers there are beginning to see stage-three withdrawal mobs.

Carl, Katia, Hekla, Eva, Donut, and a healer named Silfa prepare the captured Vermillion train. Katia spreads her transformation mass across the front as an insulated scoop reinforced with rubber against the electrified rail and covered with long spikes. Her body also anchors through the broken cab windows, and she plans to inventory dead bodies as they accumulate. Eva drives while Donut and Hekla are supposed to kill anything that survives impalement.

The first large concentration appears around station 72. As the train plows through it, Katia is repeatedly shocked and temporarily knocked unconscious. The creatures generated at station 72 are Blister Ghouls, true undead created by a soul-crystal-powered Ghoul Generator. The generator creates one Blister Ghoul for every non-undead mob that dies on the floor, linking the floor's mass withdrawal deaths to a continuously growing undead population. Silfa initially follows an instruction to withhold healing until Katia reaches low health, forcing Carl to demand immediate and repeated healing instead.

Farther up the line, heavier mobs damage Katia's spikes and the rescue party receives new information from Imani and Elle. Festering Ghouls are gathering at station 48 and merging through worm-like organisms into a single Province Boss large enough to fill the station. Wrath Ghouls are accumulating at station 36. Carl summarizes the emerging stairwell threats as Jikininki and their generator at 12, an as-yet unknown threat at 24, Wrath Ghouls at 36, the Festering-Ghoul Province Boss at 48, and the Blister Ghoul generator at 72.

Near station 101, the train enters the main horde. Gore and still-moving body parts flood the cab while Katia's health falls much faster than the collisions alone explain. Silfa flees into the engineer apartment instead of continuing to heal. Donut's focusing goggles reveal the hidden cause: Hekla has fired invisible bolts into Katia, once earlier and then again during the main assault.

Carl orders Katia to shed her added mass and finds two phased crossbow bolts embedded in her. The Dirty Little Phased Bolts hide both themselves and their entry wounds. Each inflicts Temporary Amnesia and Suffering Bleed; one drains a victim toward ten percent health and a second toward one percent. If the victim dies afterward, the item is designed to make another cause appear responsible and to avoid crawler-kill credit and skulls. Carl removes both bolts and Donut heals Katia, but Katia remains unconscious. The source establishes Hekla's deliberate use of the bolts but does not yet establish her motive.

The train stops at station 101 as trapped crawlers surge toward it and another large mob force closes in. Carl tells Donut not to turn the discovery into an immediate fight. Donut ignores him. The chapter ends when she shouts that Hekla tried to kill Katia and fires a full-strength Magic Missile directly into Hekla's face.

Donut's Magic Missile from the previous moment sends Hekla into the train wall as Eva attacks Carl and Donut. Hekla stops the fight and orders Silfa and the two mages out of the cab. Katia remains unconscious from the invisible crossbow bolts, then wakes confused and unable to remember why she was hurt. Donut accuses Hekla of betraying Katia after making her feel valued, while Hekla insists they should pause the conflict and focus on escaping.

Eva finally states that Katia was being used to provoke Carl's temper and claims they were not really going to kill her. She then mocks Katia's past losses and calls her useless. Katia, enraged, activates Rush and aims for Eva. The unpredictable skill carries her slightly off course, and she instead smashes Hekla against the train wall, killing the dungeon's number-two crawler. The System announces that Katia has claimed Hekla's 500,000-gold bounty. Carl then notices that Katia, who had been level 24 before serving as the train's cowcatcher, is now level 37.

Hekla's death immediately triggers another fight. Donut casts Second Chance on Hekla's corpse and then Clockwork Triplicate, creating three Hekla minions that push back Brynhild's Daughters. One minion throws Eva through the train window, though Katia can still see that Eva is alive in chat. Carl, Donut, and Katia seal themselves in the engine cab as stage-three monsters reach the platform. After the final Hekla minion falls, Katia secures Hekla's Vermillion key. Carl reverses the heavily loaded train away from the station while the surviving daughters pound on the locked engine door.

Carl and Donut each gain two levels, reaching 34 and 32, while Katia struggles with having killed Hekla. Donut then detects Silfa hiding in the mantaur apartment. Carl argues that Hekla likely intended Katia to die and Carl to attack Silfa, allowing Hekla's side to kill Carl and leave Donut and Mordecai available to join Brynhild's Daughters. Silfa does not confirm the full theory, but she says Eva ordered her to stop healing Katia and that Hekla told Silfa's daughters to kill Carl first if anything went wrong. She also explains that Hekla's death made Eva party leader and caused Brynhild's Daughters to begin breaking apart.

After Silfa leaves, Katia reveals that she successfully looted Hekla's unique repeating crossbow. The weapon can only be wielded by a female and gains damage and firing speed for each woman in the wielder's party, up to thirty. Li Jun later joins Carl in the engine cab. Carl plans to stop at station 75, detach the engine car, and have Li Jun drive the rest of the train back to station 36, where the crawlers can reinforce Imani's defense against the ghoul threat. Carl, Donut, and Katia will continue toward the end of the line to rescue their trapped friends.

Carl, Donut, and Katia agree to keep trying to rescue the crawlers trapped at the abyss, where roughly 500 to 600 people are already stranded without conductor hats or colored-line keys. At station 75, Carl detaches the Vermillion engine and sends Li Jun and the larger group toward station 36. Other crawlers then cooperate with Carl's rescue effort, contributing more than 700 conductor hats and fifteen colored-line keys that can activate the abyss escape portals.

The trio explores station 75 and finds a repair complex littered with the bodies of ghouls, gnolls, and hobgoblins. The armory and repair facilities appear to have been looted, while the Downward Dog bar provides access to their personal space but is not itself a protected saferoom. After cleaning up, Katia opens the rewards from Hekla's death and her recent combat. She gains access to Club Vanquisher, learns the level-three Find Crawler skill, receives the 500,000-gold bounty, and obtains the Enchanted Wrestling Belt of the Great Gorgo. The belt adds Strength and Constitution and gives her Avalanche, which doubles the effective mass of her body when she strikes something while moving.

The recap show edits Hekla's death to look deliberate rather than accidental and reveals more of Katia and Eva's third-floor separation. The updated leaderboard places Carl third, Donut fourth, and Katia eighth. Zev then appears in person. She says Odette has formally added Katia to the interview contract and warns that Loita, Hekla's former outreach representative and a member of the ruling Bloom party, is trying to take over their account. Zev also alludes to worsening political trouble at home and tells them that their chats will become public to paying viewers the next day.

The bartender at the Downward Dog is Growler Gary, a level-25 gnoll who survived the destruction of station 75 because an invisible boundary prevented him from leaving the bar. He says ghouls overran the station, a woman later tore out his throat and stole his alcohol, and he simply regenerated. Carl remembers a Cookbook note explaining that some indispensable NPCs repeatedly resurrect because they possess important information or access. When Carl asks how to reach the end of the line safely, Gary describes the station's interdiction carts: battery-powered repair vehicles that can select a rail line and, in the rapid-response version, use a front-mounted portal to clear the track.

The armory and repair shop are confirmed to have been looted, but the yard still contains auxiliary carts and ten unused rapid-response carts. Carl learns that the rapid-response cart can travel at up to five times passenger-train speed and can send anything it encounters either to a trainyard or into the abyss. The cart, however, will only start when two gnoll authorization sensors are activated at the same time. Carl and Bautista identify three separated groups of crawlers at the abyss and devise a paired-cart rescue plan for each route: the first cart will send debris and monsters into the abyss, and a second cart fifteen minutes later will send the waiting crawlers to a trainyard.

Katia tries to imitate a gnoll closely enough to satisfy the sensors, but even at 98 percent accuracy the authorization fails. Carl and Donut therefore use Growler Gary's regenerating body. Mongo kills him, and they discover that both activation plates require left hands. The rescue plan ultimately requires fourteen left hands, including a spare pair. After several cycles of killing and regeneration, Carl stops and explains the plan to Gary. Once Gary understands that the repeated deaths are being used to rescue people and strike back at those responsible for his friends' deaths, he agrees to endure the remaining repetitions and asks only for alcohol when it is over.

Carl, Donut, and Katia finish preparing six rapid-response carts for the three groups stranded at the abyss. Because the carts are nearly silent, Carl attaches alarm traps so the waiting crawlers can hear them approach. A test cart tuned to the abyss successfully transfers onto the Sinopia line while blasting "Physical," confirming that the plan can work. The group sends paired carts down the Sinopia, Grullo, and Mindaro lines, with the first cart clearing debris and monsters into the abyss and the second following fifteen minutes later to send stranded crawlers to a trainyard.

A wave of stage-three DT monsters reaches station 75, forcing the group to hide while the carts depart. Carl then rigs the remaining Vermillion engine with explosives and sends it toward the blocked approach to station 36. During the setup, Elle reports that Eva is missing even though Katia's chat confirms she is alive. A separate distant explosion kills a group that had been trying to disable a station 72 blister-ghoul generator, and Carl suspects they detonated the soul crystal. Soon afterward, Carl's own train bomb explodes among the ghouls and stage-three monsters, raising him to level 35 and his Explosives Handling skill to 11.

The trio uses another rapid-response cart, with its portal tuned to the abyss, as a movable barrier while they practice against the ghouls. They then isolate a stage-three Razor Fox to test Katia's new combat form. Katia turns herself into a shielded sentinel gun around Hekla's repeating crossbow while Carl, Donut, and Mongo attack. The creature eventually bursts, but the party receives no experience because they have not actually killed it. Its body has hatched thousands of level-one Krakaren Crotch Dumplings. Carl crushes most of the tiny creatures and burns the remaining hatchlings with moonshine. A final message from crawler Donita Grace, immediately marked as coming from a deceased crawler, warns that millions of the creatures are gathering at station 24.

The trainyard cart sent down the Mindaro line never reaches Bautista's group. Carl realizes that the second cart probably caught the first, causing its trainyard portal to transport the abyss-clearing cart away before either could be identified by its alarm song. The Sinopia and Grullo rescues did work, moving about 800 stranded crawlers toward defended stairwell stations. Carl, Donut, Katia, and Mongo therefore ride another rapid-response cart down the Mindaro line themselves, keeping its front portal tuned to the abyss while they search for the problem.

Near station 432, they encounter five crawlers on the track and switch the portal to trainyard E in time to transport them safely. At station 433, a railroad-crossing barrier appears across the track. Carl recognizes too late that it is part of the Station Mimic city boss. The cart's portal catches the appendage and transports the entire enormous mimic to trainyard E. When the group reaches Bautista and roughly 600 stranded crawlers near the abyss, Carl sees through the cart portal that the mimic now occupies much of yard E. Information relayed through Elle's manager says a giant mimic can only be made vulnerable by separating more than half of its mass at once, making a direct fight impractical.

Carl switches to a safer plan. He distributes conductor hats so Bautista's group can use the abyss portal itself, which leads them to yard H instead of the mimic-infested yard E. Carl also leaves thirty hats behind for possible stragglers. With the Mindaro group moved, just over 1,400 crawlers who had been stranded at the ends of the lines have now been transported to places where they at least have a chance to reach the stairwells. Afterward, Bautista returns his hat to Donut, and the other rescued crawlers follow his example, bowing and returning their hats in thanks. Katia had suggested the gesture.

As Bautista's group leaves the abyss area, he explains the stuffed monster figures he recovered from Miss Quill's apartment. Removing a figure's tag performs a true summoning of the represented creature, with rarer figures lasting longer and some summons potentially turning hostile. Bautista gives Carl a common Grulke Infantry figure and explains that Jaxbrin Amusements, the company that makes the figures, is now his sponsor. Carl warns him not to become dependent on a finite supply of summons and urges him to keep training his own swashbuckler skills.

Carl, Donut, Katia, and Mongo travel toward station 59 between two interdiction carts whose portals are tuned to the abyss. They pass thousands of growing Krakaren juveniles at station 24 and reach the station 59 saferoom. Katia opens her fan box and receives a Shade Gnoll riot shield and telescoping baton. The shield adds Constitution and Rooted in Place and upgrades Rush to Crowd Blast, allowing Katia to use the attack once every five minutes and damage a cone of enemies. Katia gives Carl her Auto Buckler of the Peach Pit because she cannot equip it with the new shield. Her silver benefactor box from Princess Formidable contains one Bolt of Ophiotaurus, which can suspend a deity's invulnerability for fifteen seconds if it strikes the deity directly in the eye.

The recap reveals a previously hidden stairwell at station 433 after the mimic was removed, but it also edits Carl's repeated killing of Growler Gary to omit the rescue purpose. The final floor announcement locks fifth-floor party placement to parties formed before the message, activates paid viewer access to crawler private chats, and changes inventory rules so loose liquids can no longer be stored. Mordecai then returns from his seven-day time-out with no subjective passage of time. Immediately afterward, the new inventory rule ejects the enormous quantity of blood Katia had stored while serving as the train cowcatcher, spraying it through the personal space while leaving Katia herself untouched. Carl privately notes the unusual behavior as a possible exploit.

The party buys a 25,000-gold cleaner bot to deal with the blood covering their personal space. Mordecai admits that attacking Chaco was a mistake and promises not to repeat it, then notices Carl wearing the Ring of Divine Suffering. He warns that sixth-floor hunters actively seek such rings, that the ring can make a powerful killer progressively stronger, and that forced magic activation could trigger Marked for Death against Carl's intentions. After Mordecai strikes Carl once during the argument, Carl removes the ring and agrees to discuss selling it before the sixth floor.

Mordecai studies Katia's expanded Iron Tangle map and recognizes that the named train loops reproduce the Syndicate logo when viewed from above. He explains that the abyss represents the galactic center and the lines correspond to old worm paths. He also identifies the floor's Krakaren and Pooka storyline as Borant political propaganda: the real Krakaren, more accurately translated as the Apothecary, is a collective organism, while the goatlike Plenty created the modern tunneling system that enables near-universal real-time communications. Borant's depiction turns a conspiracy theory about the Plenty and Krakaren into the floor's drug-addiction metaphor.

After the party sleeps, Mordecai installs the recovered Repair Bench and adds a second alchemy table, a metalworking table, and a Bolt-Thrower's Workshop. Katia continues working on the map and concludes that the visible network is only half of the structure. If each line has another track on its opposite side, the paired layout explains both the three-dimensional Syndicate symbol and why only six enormous station mimics exist. Mordecai recalls an earlier fourth floor in which a completed Syndicate-logo puzzle rotated and flipped everyone into a hidden chamber.

Carl connects that precedent to the current floor. The station 24 Krakaren juveniles are multiplying but staying concentrated, the province bosses occupy other stairwell stations, and the recap showed a space containing an unusual stairwell between apparent layers. He begins to suspect that the paired tracks or stations will flip or otherwise expose a hidden chamber as part of the floor's final trap. The chapter ends at the moment Carl tells the others that he thinks he has figured it out, before the mechanism is confirmed.

Carl warns crawlers throughout the Iron Tangle to abandon the stairwell stations before the suspected final trap activates. While Donut, Katia, and Elle test attacks against the growing Krakaren Juvenile Clonelings near station 24, Carl brings the Def Leppard rapid-response cart to a station 36. The cart is too large for the interior corridors, but Zhang uses the final charge of a shrinking wand to reduce it for five minutes while retaining its weight. Carl and the other crawlers move it into the central chamber, build a five-legged crane, suspend the cart vertically over the circular center, and activate its front portal facing downward toward the abyss.

When the floor timer reaches one day, the Iron Tangle announces a self-destruct sequence. Emergency escape tunnels open, the designated stairwell portals will activate in eighteen hours for a six-hour window, and gravity may shift inside the escape tunnels. Circular sections of the stairwell stations drop away and expose the hidden paired spaces. Human-sized Krakaren monsters begin falling into the chambers from below. At Carl's station 36, however, the suspended cart catches thousands of them and sends them directly to the abyss. The defenders fortify the surrounding chokepoints as additional Krakaren juveniles and ghouls arrive through the normal passages.

During the defense Carl meets Tserendolgor, a level-27 Dog Soldier and Crisper operating a flamethrower, while chat messages from Ronaldo Qu and Gwendolyn Duet confirm how badly other stairwell stations are being overrun. Carl also learns that awakened dwarves and gremlins killed Madison and that Fire Brandy now understands more of the artificial nature of her situation. Elsewhere, Bautista's group is pushed away from both station 72 and station 60 by Krakaren monsters, ghouls, and mantaurs.

As the waves intensify, Katia uses Crowd Blast to smash through a breached chokepoint, allowing Carl and Donut to destroy clustered enemies with boom jugs and Puddle Jump back to safety. Two nearby soul-crystal generators then explode. Mordecai agrees with Carl's suspicion that simultaneous local deaths are overloading the smaller soul crystals like fuses. The chapter ends with Carl declaring that he has a new idea and noting that it is relevant that Mordecai just mentioned the Nightmare.

Elle confirms that the station 12 soul crystal has burned out and that its newly opened hole leads through the gravity-shifting "noodle" to an upside-down paired chamber. Carl decides to retrieve his remaining rapid-response cart, and Li Jun, Zhang, and Li Na volunteer to help. Before leaving, Li Na proposes removing the province boss in the station 36 directly across the noodle. The defenders raise the suspended Def Leppard cart just enough for Donut to provoke the boss with Magic Missile, then lower the abyss portal back into place. The boss strikes the portal and is transported away.

When the portal is briefly switched off, Carl discovers Prepotente and Miriam Dom in the opposite station. Prepotente says he had the province boss asleep and was slowly lowering its blood pressure toward cardiac arrest; he believes killing it would have detonated multiple nearby soul crystals. After a hostile exchange, Miriam calms and disciplines Prepotente, and their group leaves to find another boss. Carl's team then fights through the corridors to the remaining cart. On the way toward trainyard E, its portal removes a huge Krakaren neighborhood boss at station 24.

At trainyard E, the giant station mimic and its minions make a direct crossing too dangerous, and two mantaurs guard the employee-line entrance that Carl needs to reach with the cart and the Nightmare. Carl changes plans and asks Mordecai for exact deity-summoning mechanics. Mordecai says an involuntarily summoned deity remains for the vessel's level plus the god's level; a level-40 mantaur carrying level-250 Grull would therefore hold him for 290 seconds. A summoned deity expands to fill its chamber, can be summoned again immediately after disappearing, and can be pulled from one vessel into another summoning. Carl records the information in the Dungeon Anarchist's Cookbook.

The party lures the two mantaurs into the tunnel. Katia and Li Na immobilize one, while Li Jun, Donut, Mongo, and Carl batter the second until its Grull-summoning countdown begins. They try to send that mantaur through the rapid-response cart's portal before Grull manifests. At the last second, however, the mantaur grips Carl's numb foot. The portal pulls both the mantaur and Carl through, ending the chapter with Carl unexpectedly transported along with the vessel.

The mantaur drags Carl through the rapid-response portal into trainyard E just before its Grull summoning completes. A Death Challenge immediately activates, trapping Carl inside the city-boss arena with the level-90 Mimic Rex and the incoming level-250 war god. The broadcast also reveals that Prince Maestro survived the events of the previous floor and is Grull's sponsor for his Dungeon Crawler World debut. Grull manifests through the mantaur vessel with Maestro's features while the Mimic attacks both Carl and the god.

Carl uses a thirty-second invisibility potion to evade the Mimic's tongue and minions, but the trainyard's boss barrier prevents him from escaping. Grull kills the Mimic Rex with a single axe strike and then hunts Carl through the wreckage. Carl drinks Mordecai's Special Brew, gaining thirty seconds of extreme healing that allows him to survive repeated shockwaves, being crushed beneath Grull's hoof, and other otherwise fatal impacts. Grull, speaking through Maestro, mocks Earth and tells Carl that Katia's Bolt of Ophiotaurus would not yet let them hurt him.

Elle enters the arena long enough to distract Grull with icicles. Katia then transforms into an accurate copy of Carl and taunts the god from across the trainyard, drawing Grull away from the real Carl. Li Na, Li Jun, Donut, and Mongo enter through the moving portal cart. They have brought the second mantaur with them after Li Na removed most of its body while repeatedly healing it, making the still-living vessel easier to transport.

Carl punches the second mantaur until its Grull-summoning countdown begins. As Grull turns back toward them, the group throws the mantaur into the portal with one second remaining. The new summoning pulls Grull out of trainyard E and into the abyss, ending the Death Challenge after the Mimic's death. The Nightmare arrives immediately afterward, and Carl collapses from exhaustion after the successful transfer.

With the Mimic Rex dead, Carl retrieves the Map of the Stars from its remains, adding boss locations and descriptions across a large section of his map. He and the others reposition the rapid-response cart on the employee track so its portal can send the Nightmare into the abyss. Reports indicate that the Mimic's death and Grull's arrival in the pit have already caused additional ghoul-generator failures, but Carl still wants one large simultaneous kill event to overload more of the remaining soul crystals.

Fire Brandy and Tizquick refuse to leave the Nightmare. Brandy says she has remembered previous dungeon incarnations in which she repeatedly gave birth to children who were then taken from her, and she refuses to let the dungeon use her that way again. Tizquick, now aware that his daughter was fabricated, also chooses to remain and promises to make the train explode before it reaches the bottom of the abyss. Carl accepts their decision, adds explosive satchels, and promises Brandy that the crawlers and awakened NPCs should not be enemies.

The Nightmare drives through the portal and detonates in the abyss. The resulting kills generate a flood of experience for Carl, who receives at least partial credit, reaches level 41, and gains a fan box. Bautista reports that a generator near his group has exploded, allowing them to move toward the stairwells. Carl reflects on Fire Brandy and Tizquick's choices and on the fact that Donut, Katia, Elle, Li Jun, Li Na, and the others repeatedly risked themselves to save him. He recognizes how dependent his survival has become on other people.

Back at station 36, the stairwell is already open and the larger group has waited for Carl's party before descending. Agatha unexpectedly appears, still a level-8 human without a class, and pushes her shopping cart down the stairwell despite Imani's confusion. Loita then messages that Odette is waiting and that she will join them in the green room to discuss their new arrangement; Donut immediately asks where Zev is.

The chapter closes with a new entry from Carl in the Dungeon Anarchist's Cookbook. He writes that the dungeon's NPCs and mobs are victims too, but concludes that merely surviving and talking about destroying the system is insufficient. Addressing the twenty-four prior Cookbook authors, Carl promises that he will find a way to attack the people running the dungeon as well: "They will not break me. But I will break them."
