Dungeon
The World Dungeon is an eighteen-level subterranean maze created beneath the Earth's surface from the planet's own repurposed matter following the transformation.
The Dungeon, formally the 18-Level World Dungeon, is a vast subterranean structure built beneath the planet's surface out of the matter mined from the world above. The Borant Corporation, which holds regency over the solar system, chose it as option 3 for letting surviving humans reclaim their lost matter. Borant keeps every right to broadcast, exploit and control the dungeon, so long as it follows Syndicate regulations on resource reclamation, and a neutral Syndicate observer AI supervises its creation.
The first-level entrances stay open for a single hour. Anyone who goes in cannot leave until all 18 levels are complete or certain other requirements are met, and completing level 18 hands regency of the planet to the successor. Anyone who stays outside has to survive on the surface alone.
