Kossith. Sort of. The Kossith are more like our... genetic ancestors. The Qunari have done some really weird things with our genetics through selective breeding and some other things, I think, so we're not really Kossith anymore. We probably don't look like them, at least.
I say I'm Qunari. Nobody but "actual Qunari" calls us much else, but if you say that in front of a real Qunari they'll get all flustered and get angry at you for reasons they won't explain, because you're too dumb to understand what they're talking about. The ones out of Par Vollen are pricks obsessed with semantics.
