World Dungeon · Systems and rules
World Dungeon
The World Dungeon is the deadly competition forced on Earth’s survivors after the Collapse. Crawlers descend through a series of floors, fighting monsters and completing challenges while an interstellar audience watches. The rules change as they go, and the people running the show have their own interests in who survives.[1]
Choose Book 1 or later above to read this section.
Structure
The dungeon is announced as an eighteen-floor competition. Reaching the bottom is the promised route to winning, although no crawler is guaranteed to make it that far.[1]
Choose Book 1 or later above to read this section.
Immediate objective
Crawlers must reach the next floor before the one they are on collapses. Each floor has its own deadline and conditions for opening the stairs.[1]

Who explains the rules
System announcements provide the official rules, while guides such as Mordecai help crawlers understand them. The organizers can change those rules, and this season often unfolds differently from Mordecai’s expectations.[1]

History
Book 1
Dungeon Crawler Carl
Entering the dungeon
After Earth’s buildings collapse, an announcement gives survivors a short time to enter the dungeon. Carl goes inside because he sees little chance of surviving outside. The organizers promise control of Earth to anyone who completes all eighteen floors. Mordecai later explains that crawlers can also negotiate exit deals from the tenth floor onward, with better offers available the deeper they go.
Crawlers have five days to get through the first floor. A countdown tracks the time remaining while tutorial guilds introduce them to their new abilities and equipment. A crawler’s level measures experience and development; it is separate from the floor number.[2]
Deadlines and descent are season rules
Under the early descent rules, crawlers who reach the next floor ahead of time are held in stasis until the previous floor collapses. Those who descend during the final six hours can move around immediately. Later floors have their own arrangements. Even the time available can change: the second floor is shortened to six days after guides had expected ten.
Mordecai explains that the early floors do not cover the whole planet. Carl notices districts that seem to match places on Earth, but has only seen a small part of the dungeon. The guarded stairwell arena also teaches him that reaching a staircase can involve another dangerous encounter.
Zev explains that every third floor is part of a connected setting that exists before the crawlers arrive. Its inhabitants have lives and ongoing conflicts of their own. As Carl travels deeper, those people and their histories become an increasingly important part of the crawl.[3]

Book 2
Carl’s Doomsday Scenario
Beyond the training floors
The third floor begins in a hall beneath an artificial sky, with eight days until collapse. Mordecai describes the first two floors as training. He also warns Carl about outside participants he may meet later: hunters on the sixth floor, gods from the fourth onward, and wealthy tourists on the eighteenth.
The Over City quest reveals hidden stairs to the fourth floor when Carl completes it. Progress can depend on solving a quest rather than killing a boss. Carl also learns that paying visitors can have special protection: someone removed from danger may survive outside the dungeon even when the encounter appears fatal.[4]

Book 3
The Dungeon Anarchist’s Cookbook
A floor can make waiting compulsory
The fourth floor, the Iron Tangle, forces crawlers to navigate a complicated train network. Its stairs only open during the final six hours, so finding them early is not enough. Carl’s group must survive until then and keep a route to an exit as the rail system breaks down.
Far fewer crawlers reach the Iron Tangle than Mordecai would normally expect. His experience helps the group prepare, but the unusually high death toll is another sign that this season is departing from familiar patterns.[5]

Book 4
The Gate of the Feral Gods
A shared route out of the bubbles
The fifth floor divides crawlers among isolated bubbles. Each bubble contains four quadrants, each with a castle. Occupying a castle’s throne room or killing its boss liberates that quadrant, allowing crawlers who started there to cross its boundaries. All four castles must be conquered before the bubble’s stairs can be used.
Opening the stairs does not make them easy to reach. Wreckage can block an exit, and changes in one quadrant can endanger crawlers in another. Carl’s group eventually discovers that a detached stairwell platform can be stored in inventory and moved, giving them a way to bring an exit to people who need it.[6]

Book 5
The Butcher’s Masquerade
The hunt and the bypassed race
After an initial grace period, hunters from outside the dungeon are allowed to pursue crawlers on the sixth floor. The organizers continue changing conditions, restricting the hunters’ communications and altering the environment. Crawlers cannot rely on the floor remaining as it was when they arrived.
The system announces a plan to swap the seventh and eighth floors, but the crawlers ultimately arrive at the Great Race on Floor Seven. Prepotente recognizes the maze’s fairy-tale design and uses gifts from his sponsor to destroy it. Portals then pull the crawlers into the eighth floor, bypassing the intended race.[7]

Book 6
The Eye of the Bedlam Bride
Different starting regions, shared consequences
Escaping the eighth floor requires surviving a spell that pulls living creatures, objects and buildings upward. Crawlers gather beneath cleared vestibules at their assigned regional stairs, which are protected from the pull. As the spell tears away the rooms above them, the sheltered crawlers can descend.
Before Faction Wars, Carl uses the Posse’s final emergency action to break a deadlocked vote. The resulting audience polls remove faction-sponsor safety protections, establish a protected NPC home faction, speed up pet leveling and expand the battlefield. These changes are in force when the ninth floor begins.[8]

Book 7
This Inevitable Ruin
A war with its own clock
Faction Wars begins with a sixty-hour ceasefire, which can end early if every team declares itself ready. The floor lasts thirty days, or ninety hours after a winner is declared if that comes sooner. As teams are eliminated, the war moves into new phases, including a throne phase for the final four teams.
Withdrawing, capitulating and being defeated carry different consequences during the war. The stairwell chambers open once the conflict ends, or when only thirty hours remain before collapse. Until then, finding a chamber does not allow a crawler to leave.[9]

Book 8
A Parade of Horribles
The eighteenth-floor door opens
The AI declares the eleventh-floor arena won even though both bosses are still alive. It opens the door on the eighteenth floor and stops the collapse timers below Eleven until someone wins the Ascendency. The eleventh floor’s timer keeps running, so the crawlers still have to get out.
Carl decides to prevent anyone from winning the Ascendency until the people trapped in the dungeon can escape. The Victory Interlude confirms that the crawlers have reached the twelfth floor, but the wider rescue is still ahead of them. They have survived the arena, not completed the original eighteen-floor competition.[10]
