If anyone has seen lost girl they will know what I mean by Fae. If not then my idea is based on that show there are two Fae factions, Light and dark a.k.a Good and evil...in their sense.
Then there are humans which all Fae except a few feed off of. 

My idea isn't totally fleshed out yet as I need to see if anyone is intersted in an RP based off of lost girl.
Also there is quite a long list of Fae, so there will be plenty of species of Fae to chose from.

P.s if someone has seen the whole series of lost girl, then no spoilers I'm only at the begining of season 2.
