Dreams.

I had a dream that Revan specifically created fairies for Arandor in the expansion. And Arandor created a fairy girl.

That's how fairies used to be in the expansion. And there were lamias. And some other semi-furries, locked in reservations. But nobody played as them, and they weren't even found among the NPCs. I'm not entirely sure why they're not in Schism. Did they go extinct or migrate?
