I kinda don't like the idea of faeries. Yes, I understand they are a part of folklore, just as long if not longer with the witches, werewolves, and vampires, but I never saw them in their proper light.

I have seen faeries shown more as positive little things when really they are annoying clever misfits. So, I see the concept of adding them a bit childish. I find that adding things that don't fit the concept can be seen as overwhelming, when it doesn't have to be. If we are going to add faeries, then I would hope they would be shown in the proper light they deserve.

I'm just humbly stating my opinion.
