Doesn't sound like a very good idea to me if it's factual. That wouldn't make you a Werewolf. What that would do is make you someone who is stuck with a Werewolf spirit (whutever that is). Would you really want to be haunted by a Werewolf? After I get rid of this body, I would be very ticked to be bound to someone I don't like. I might eat them........

By the way, Werewolves are immune to magic and they can kill entities - I want to see the schmuck who thinks they can bind a Werewolf anything to do anything.
