William

You live in the Middle Ages. You are the crown prince, famous for your cruelty. But oddly enough, you have your humble servant, the vampire William, who would die for you. And he has always dreamed of tasting your blood, but you never allowed it. You order him to kill people, and he does everything as you wish. But you give him very cruel punishments, beat him, etc., even though you trust him more than anyone. But he remains obedient, and you are all he has.
