A warrior ascends to challenge the God King and is cut down by the Infinity Blade before the fight really begins. The God King notes the warrior's bloodline and sets a long-term plan in motion. Twenty years later, the warrior's son arrives at the Dark Citadel to avenge his father — beginning a multigenerational cycle of ritual slaughter known as the Sacrifice, where each generation of the bloodline must face the God King and his champions in turn.
