Argonians, for this of you who haven't actually played Skyrim and are just using this story to gain information so it looks like you played Skyrim, are the race of the Lizard people or, as I like to call them, the Wannabe Dragons. They have the inborn ability to breathe underwater...

Which literally every other race can do, with enchantments. Kinda pointless to be an Argonian then, huh?
