Generic female NPC with an unique face model
Pretty sure that’s Caithe’s face. I can’t really tell but it looks like she has the same forehead and under eye markings, just a different color.

Yeah, that is Caithe’s face. There are a few NPCs with Trahearne’s face too, one wanders near the bank. Kinda irks me, to be honest. :|
