What if the Avatar was found a few years later than in the original timeline? Sokka has become a brooding, vengeful warrior at the South Pole, waging a one man crusade against the Fire Nation. One day, he picks a target that will change his life, and give him the opportunity to change the whole world. Sokkla, Kataang, maybe other ships later.
