Mortals do not and will not understand but most Celestials or Primogenitors who learn you have one of the [Keys] will come at you with everything they got and will not stop until they die or get the book from you."

No death, no rest, and not even the right to fall into insanity. Endless and unrestrained agony. For all eternity."
