Fire Nation Brothers

People say Sozin was the first villain in Avatar. What if he was banished? When Gyatso dies, brothers Zuko and Aang's lives are completely uprooted. Aang is suddenly more than just the one kid Zuko knows who can bend two elements. They work together to try and save the air nomads, but Ozai is a formidable enemy. It will take more than two scared brothers to defeat him. Avatar AU.
