Work continues on my S.M.A.R.T. Fantasy setting and I am interested in adding the ideas of others to the mix. What I'm looking for is interesting ideas for fantasy races that I can drop into the setting to add some thrill and excitement. I don't want to take ideas from commercial fiction (because of copyright problems) and I don't want to take ideas that have been worked to death (Dwarves, Elves, Merefolk, traditional Fae, Ents, Centaurs, Demons, Angels, Goblins, Trolls, etc.) I'm looking for interesting non-human beings that neither would fully dominate a world setting nor be too close to human to culture/appearance that they become 'actors in latex' llike you'd find on many common SF settings.
So, anyone got some ideas that they'd be willing to expose to the masses and players that are really weird, interesting, playable as PCs etc.?
