With Earth on the verge of destruction, ships were loaded with refugees and artifacts and sent into space. They crashed on a foreign planet. The ships' AIs attempted to recreate Earth but encountered software errors, and those errors manifested as monsters that have roamed the landscape ever since. One thousand years later, the player wakes and must fight these monsters while working with the planet's native Guardians — who have every reason to resent what humanity's arrival did to their home but are willing to cooperate in exchange for alcohol.
