Okay, I currently have the Realms of Fae broken up into five categories:
Summer/Seelie Court
Winter/Unseelie Court
Wild Hunt/Court of the Erlking
North Pole/Court of Grandfather Frost*
Wyldfae
*Please note, the existence of a Winter-aligned 'kindly' fae has been hinted at in the game, as well as by Jim, by evidence of its existence, lead by a Sidhe Brownie is still more conjecture at present.

+Please note, ogres serve both Summer and Winter, depending on which court they choose to serve. It is also quite possible that a number of the other Fae start out as Wyldfae, and then choose which court to belong to. Therefore though the only Centaur from the novels, Korrick, was a part of the Court of Aurora, the Summer Lady, there might also be Centaurs in service to the Winter Court.
?Please note, svartalf (from Norse mythos) are mentioned in the novels, but they might not be Fae, instead being something entirely different.
I need to re-read parts of Summer Knight and Turn Coat, as they can likely provide a few more examples of fae.
