If the Argonian ever decide to fight against the Thalmor, they're screwed.According to one of the books in the game, when the daedra invaded Black Marsh the Hist called all the Argonians back and their numbers were so great, the daedra had to close the gates to stop from being flooded and out-numbered.Immortal demons are afraid of the Argonians, I don't think the Thalmor would stand much of a chance against them.
I think its because the Daedra invaded Black Marsh. The Argonians were fighting on their terrain, which they are used too. Black Marsh is a very hostile enviroment for any other race, which gives the Argonians a great advantage.
I think if the Argonians just had to fight in another province, or just head up with another race, they would get spanked. Im not very clear on alot of the lore though, so I could be wrong
