Magic Forums

I was looking online just for fun about information on werewolves and I happened to come across many seemingly possible historical cases of sightings in north America within the last century. The one that particularly caught my attention was known as the bray road beast. I also have a good friend that has, until recently, studied "black magic" and a certain summoning spell had gone wrong. according to him, my sister, and her fiancee, they were in the woods when they say a very big,tall, muscular creature ,that looked like a werewolf, moving through the trees. They also messed around with the necronomicon(don't know if that's relevant, haven't researched much about it). As much as I'd love to believe in such a thing my scientific mind has a tendency to want and need facts before making up it's mind. Therefore I'm asking whoever has the knowledge of such a thing if it is possible that a werewolf might exist. I'm looking for an answer that has both an open mind and a healthy amount of skepticism.
