" He comes from the grave, his body a home of worms and filth. No life in his eyes, no warmth of his skin, no beating of his breast. His soul, as empty and dark as the night sky. He laughs at the blade, spits at the arrow, for they will not harm his flesh. For eternity, he will walk the earth, smelling the sweet blood of the living, feasting upon the bones of the damned. Beware, for he is the living dead. —OBSCURE HINDU TEXT, CIRCA 1000 B.C.E. "
