Davriel Cane, the Man of the Manor, Lord Greywater (he goes by many names) is the lord who rules over Verlasen and a few nearby villages. He is a diabolist, a man who studies and summons demons. He makes contracts with them, offering his soul should they complete the contract. He's very good at making sure they never will. He is also a planeswalker, able to jump from world to world. He only recently arrived on Innistrad because he is on the run. His magic allows him to steal magic skills from others temporarily, though he has also stolen a creature he calls the Entity that lives in his mind. It makes him virtually immortal.

Though he once ruled a world he has decided that it was not worth the price in blood and death. Instead he plays at being a lazy fop of a man, concerned primarily in having easy access to his tea and taking ample naps. Despite his easygoing and lazy attitude, he's extremely clever, quickly deducing the cause of deaths as well as applying magic skills in surprising ways.

Being a planeswalker, Davriel is the most likely character here to return in future stories. Should he do so, you will be asked to reprise the role.
