Location from Dungeon Crawler Carl by Matt Dinniman
An eighteen-floor inverted megastructure carved beneath Earth's collapsed surface — a lethal game show broadcast to quintillions of alien viewers across the Syndicate.
The World Dungeon is a planetary-scale death trap created when the Borant Corporation collapsed Earth's surface and funneled nearly thirteen million humans into an eighteen-level gauntlet. Each floor operates under unique rules and themes — from tutorial corridors and goblin-infested cities to open hunting grounds and faction war battlefields. The dungeon runs on the Primal Engine, an ancient planetary power source, and is administered by a snarky Macro AI with a foot fetish and a grudge against its corporate overlords. Floors shrink as crawlers descend, culling survivors from millions to dozens. Safe rooms provide brief respite; stairwells connect levels but may hold crawlers in stasis. The entire spectacle is broadcast live to the galaxy as Dungeon Crawler World: Earth, with alien sponsors betting on favorites, hunters entering as tourists, and factions waging wars over territory. Behind the entertainment lies a darker purpose: mining rare primal elements that fuel galactic civilization.
A titanic subterranean complex shaped like an inverted triangle, each floor smaller than the last. The upper levels are hewn from rough stone lit by torches and bioluminescent lichen; lower floors open into artificial skies, jungle canopies, train networks, and volcanic cityscapes. The deepest level holds Scolopendra's lair. The whole structure is threaded with stairwells marked by massive double doors engraved with the Kua-Tin symbol.
