William Twining has it all - a sharp intelligence, dashing good looks, and a noble station in life. There's only one problem: he's broke. William's logical worldview is about to take a hit when he comes across a mystical seal which he unintentionally uses to summon a demon. Dantalion, a Grand Duke of Hell, informs the young nobleman of his destiny - that he is the new Elector whose sole responsibility is to appoint the next ruler of Hell in place of Lucifer. Such news might drive a lesser man mad, but not William Twining.
