I have only run into the two cultists who attack you and start the quest. Both of them were Dunmer. Anybody have cultists of a different race? Or are they all Dunmer?

Edit: The title should say Cultists, not Clutists. Derp

I don't know to be honest.

i could have sworn one of them that i killed was a nord..

Is a clute something like a cross between a lute and a cow bell?

Yeah, something like that.
