On a battlefield a demon spirit enters the body of a dying mercenary. He is reborn and defeats twenty rulers in bloody combat. He goes on to found the reign of the Demonlord Raith. At the height of his power, his doom is foretold by a shaman: "When the night turns violent and the moon bleeds, gripped by the skeletal fingers of death...a child will rise to face the demon in combat...and the lord of demons will fall by the hand of...the WeaponLord."
