This history follows the adventures of two of these beings as they travel from the skies of an ancient planet to the realm of the gods, and then onwards to the freezing landscape of a new world, before finally encountering the subterranean regions of the Gaki. These creatures are a strange race indeed, inexorably driven by an insatiable hunger towards madness, to an insanity that holds within itself the key to the next stage of their path towards ultimate knowledge.
