The Craesto Authority is the totalitarian governmental body that governs the megastructure, and has been for as long as anyone can remember.
Levels that has transformed into huge imitations of humanity's mytical home of origin. Roamed by monster machines and beasts, they are seen as a safe haven from the oppresive Authority, and a source of exploration for Lost Scavengers.
Secluded. Safe. Protected. Filled with secrets and unknown dangers. That is Craesto Welk: an near ancient orblike megastructure that silently spins through space. A relic from a mythical past.
