Merfolk in Eberron?

[GwydapLlew]

I'm aware of the sahaguin presence in Eberron, but what about merfolk? I'm curious, as I may be starting a solo campaign with a player who is interested in playing the race.

(I'm quite capable of developing my own merfolk society, but I always like to see what 'official' information is out there.)

I've been reading through the books lately and I don't recall anything on the Merpeople.
