Purgatory

Purgatory is not a gentle place, it is a writhing dump of all that has died in many worlds. Endless deserts of pale sand are stalked by parasitic fish. Storm-cloaked mountain tops hide ungodly things above and below. The Garden waits for you at the end of time.

Purgatory is the universe where the game takes place and where Nowak and the various characters evolve. Composed of X different places, according to Bosch, it is impossible to move around in it because of its particular geometry.
