Mordred, an iron fisted warlock, and his armies lay siege to Camelot, seeking to establish the dominance of magic-wielding mages over humankind. Uther Pendragon, king of the Britons, infiltrates Mordred's lair and beheads him, destroying his forces and saving Camelot. Later that evening, Uther's treacherous brother Vortigern, who covets the throne, orchestrates a coup and sacrifices his wife Elsa to sea witches in order to summon a demon knight, who kills Uther's wife and slays him in combat. The only survivor is Uther's son, who drifts away in a boat and eventually winds up in Londinium, where he is found and raised by prostitutes, who name him Arthur.
