One thing is constantly tearing at my mind at the moment. The question 'What enemy do werewolves have?'
Vampire comes to mind immediately (yes, I read Twilight too ;) ) but that is a bit cliché. Is there nothing else? Some kind of demon or something?
I’m not so well versed in demon lore ;) so I don’t know which one would make a good werewolf opponent..
Of course, one can always invent an enemy/demon…
So, any suggestions anyone?
