The Fey part is cool, gives me some ideas, and there are some nice (nasty) ones available in PF. He would probably get more immediate use from having beastmen (figuring they would probably be Monstrous Humanoids) as a favoured enemy, but perhaps more long term use from Fey. At least, based on the ideas I've had so far...
Oh dear...what have I done?! I'll leave it as Fey. Happy with the background reading - its amusing a fairly hefty half-orc being taken down by what passes for PF Fairies.

Semi-related question. What's the likely value in buying a horse with the 1000gp starting gold? They aren't particularly cheap, and to be honest don't get a lot of use in a standard 3.5/PF game.
