We're gonna make a minor alteration to the storyline regarding the Airbenders with regards to ensuring historical accuracy by making the Airbenders a religious order that Aang was the born the religious head of, and that that it was Earth Bender death squads that exterminated them who in turn forced a young Aang to flee into that ball of ice.

But actually that ball of Ice is actually the fire nation, and he's there to petition them to reveal to the world the terrible war crimes of the Earth Kingdom.
