"Castlevania" mainly takes place in the castle of Count Dracula, who resurrects every hundred years to take over the world. With the exception of some games, the players assume the role of the Belmonts, a clan of vampire hunters who have defeated Dracula for centuries with the Vampire Killer. The Vampire Killer is a legendary whip that is passed down to their successors and can only be used by them. In "Castlevania: Bloodlines", the whip has been inherited by John Morris, the son of Quincey Morris, who is a distant descendant of the Belmonts. Other recurring characters throughout the series include the dhampir Alucard, who sides with Trevor Belmont against his father Dracula in "Dracula's Curse". Trevor is also joined by Sypha Belnades, a vampire hunter who fights using magic and marries Trevor by the end of the game. Descendants of the Belnades clan, such as Carrie Fernandez and Yoko Belnades, would also make appearances as playable characters in later titles.
