All in all, I don't really mind adding in other supernatural creatures. I'm not sure about making vampires and werewolves other forms of fae though.<br/><br/>Thinking about it, I'd prefer to keep them as distinct entities. The vampires, perhaps, have watched the fae 'experiment' with coming out, and started working towards it themselves, hence the rise in urban fantasy as a genre / more vampire movies, the focus shifting from vampires as voracious predators to something dark and sexy. Maybe they were even partly responsible for the creation of Goth culture, getting some of the unseelie fae to help inspire the first waves of goth music and art.
