I'd say the Argonians are fairly close to original (or as original as you can get in such a developed genre). Having said that, I can't remember what they're from, but in a popular book/movie/game (I forget which) there was a race descended from dragons that were a little like Argonians.

Or maybe the devs thought of Black Marsh first and then designed a race that would fit it.
