Cal Warden is a supervillain and vampire operating in Columbus, Ohio. Rather than hunt people for blood, he instead runs a meth lab. Selling the meth on the streets, he can buy as much blood from underpaid medical workers as he needs.
Cal is a vampire in the vein of Twilight, in that he sparkles in the sun. He has an army of brainwashed fangirls who will do anything he asks of them.
