Shouldn't most of the argonians be dead because of what happened in the books?
Well the ones in black marsh anyway.
I haven't really stopped to read any of the books, aside from one lengthy one on the Great War, what happened?
also, there are so few Argonians in Skyrim because it's too cold, simple as that.
If you guys haven't been to Markath I suggest heading over there its a really cool looking city, supposedly built by the Dwemer.
