Peter Stubbe’s magic belt

I find the question about Peter Stubbe’s magic belt very interesting. Magic is not really associated with werewolves which is what makes the whole scenario so strange. Yes, when you talk about witches and demons and even some other werecreatures magic is sometimes discussed, however I cant really think of any other case where magic is linked with werewolves. Werewolves do not traditionally have the ability to perform magic, nor are they magical creatures. And we know that today’s werewolf does not need a “magic” belt to transform. Which brings us to the possible conclusion that perhaps this belt was given to Peter from a witch or some other magic-oriented person. I would say it was not Peter himself that was cursed with this magic, but that the witch perhaps cursed the belt itself. If this is the case, I would say that werewolves were already in existence at this point, hidden in the shadows away from the human eye, and this magic belt transformed Peter into one for some inexplicable reason. Perhaps to give werewolves a bad name?
