This game has no prologue, so it's unclear what it's about. It starts at "grass" (yep, lower-case titles), in a land surrounded by blackened trees, a crater rim, red smokey sky and a watchtower in the distance. It sounds like something out of Lord of the Rings, but one of the objects is described as a "postapocalyptic dreamcatcher" and the title indicates it's 2113, so we deduce that it's set in a post-apocalyptic future.
Anyway, everyone has their candles, lanterns and pumpkins out, so it's obviously Halloween. Time for some trick-or-treating!
