“Thanatos has been chained,” Mars announced. “The Doors of Death have been forced open, and no one is policing them—at least, not impartially. Gaea allows our enemies to pour forth into the world of mortals. Her sons the giants are mustering armies against you—armies that you will not be able to kill. Unless Death is unleashed to return to his duties, you will be overrun. You must find Thanatos and free him from the giants. Only he can reverse the tide.”
