Who's Next For the Overlord's Harem? (Patreon)

The thought came to me that I'm not certain which race to get into next for Overlord's Harem. I've already got the goblins, kobolds, dwarves, minotaurs and orcs covered, and plan to keep expanding it while checking in on the others a little. It'll probably reach capacity at some point and get into dealing with them in particular, but the real question is, who gets added next?
