From this single image, a vast mythos emerged. The Backrooms is said to consist of an infinite number of procedurally generated levels, each with its own layout, rules, hazards, and entities. While Level 0 is relatively benign (albeit psychologically disorienting), later levels introduce increasingly dangerous challenges. Some levels resemble Backrooms industrial wastelands, flooded corridors, dark forests, or decaying malls, while others defy physical laws altogether. The further one descends, the more reality seems to break apart.
