For millennia uncounted humanity has struggled against nightmarish creatures hidden in the shadows of Creation. Though these Godless monstrosities are whispered to be legion, none share a more intertwined destiny with mankind than the Non-Human. Origins lost to antiquity, an instinctual desire drives humanity to eradicate them to the last, for influence between the two species breeds a parasitic self-destructive existence. Thus a war of genocide has waged in secret, in which the ranks of Non-Human suffer rapid extinction in the wake of human supremacy. Yet mankind’s final victory is not inevitable, for a guarded prophecy claims a messiah born unto the Non-Human shall deliver them into salvation: a fate which could only mean humanity’s damnation.
