William
William was a young upper class gentleman. He lived with his mother. His time was filled with parties and writing poetry. Deeply in, unrequited, love with a girl named Cesily. Laughed at by his peers he had no close friends. One night he writes one of his "Bloody awful" poems and confesses his love to Cesily. She turns down his advances, telling him he is beneath him. He runs, broken hearted, only to bump into an evil vampire, Drusilla. He takes her for a pickpocket, she tells him what she wants is not his money. Offering him a different lifestyle, he lets her bite him.
