I am currently in the world building stage, and have been for quite some time but that's another issue, and so far I know that my protagonist is a werewolf. I've always loved werewolves and personally felt that they have not had as much exploration as vampires, since they are often tacked on to vampire stories and werewolf folklore and mythology is rarely explored. But I'm not sure how to explain the origin of werewolves. There are no other shapeshifting creatures in the story. Yet, I feel like something is missing. I was thinking of adding witches, since there were witch-werewolf hunts in the 17th century so they are connected in some way. But I don't really want my story to venture too far outside the society of werewolves. So I feel like something is missing from the overal story world, but I don't want the addition of witches to seem tacked on, especially since I will not delve too much into the society of witches and I would only make the antagonist a witch anyways. I also can't find any mythology concerning werewolves and another supernatural creature. To be honest, I just feel like werewolves being the only supernatural beings will make the world seem empty somehow, like there should be something else too. Any advice concerning this problem? And for the record I really do not want to add vampires.
