If you have Dawnguard, the royal vampire armor actually looks really similar to what he wears. And I think he kinda looks more like a dark elf than a redguard.
You figure Redguard since they and the Gerudo are both from the desert. But yeah, I see why you might use a Dark Elf. Hmm. that's a tough one. --- Carry we who die in battle over land and sea across the rainbow bridge, to Valhalla! Odin's waiting for me!
