Agreus is the brother of the deceased Pan, coming to Dracula's Castle to seek revenge against his killer, the vampire lord Dracula. First Agreus lures Dracula into the Castle's gardens with a fragment of the Mirror of Fate knowing that he would seek the fragment for his son Trevor Belmont. As Dracula attempts to claim the fragment, Agreus steals it from him and informs the vampire that he intends to avenge Pan's death. Dracula tries to reason with Agreus that his brother chose to sacrifice himself for a cause that he believed in, but Agreus retorts that Pan only died to serve his quest for power. Declaring that Dracula would pay for what he had done, Agreus retreats into the maze, goading the vampire to follow him.
