When first approached, Seridur claims to lead a small vampire-hunting group, and to be in search of a specific vampire, Roland Jenseric. He is involved in the quest "Order of the Virtuous Blood," in which he tells the Hero Roland's location and requests that he be killed. However, Seridur is in fact a vampire himself. At some point, he came into contact with Relfina, Roland's wife, whom he used. She supposedly had been cheating (possibly being controlled by Seridur) for some time. One night, Seridur met Relfina and attempted to bite her, but Roland, who was following them, revealed himself.
