Until The Water Tribe Attacked

(I'll think of a better title later)
Where instead of the fire nation attacking, the water tribe attacked. Katara learned how to use bloodbending at a young age and has even developed the ability to do without using the full moon. Sokka is a very powerful warrior along side his father. This happen in Aang's timeline and he didn't get stuck in the iceberg. He helps Azula and Zuko.

- Also it's kind of a modern au, because it's easier for me to write in that style, but I don't know of you'll notice too much anyways

(Inspired by some fanart I saw on Instagram about what if the water tribe was the enemy and Azula and Zuko were on Aang's side. Also Aang and Katara's relationship is a little inspired by Catradora if y'all ever seen She-ra)
