Aang and Katara's new life

Water, earth, fire and air. Long ago the four nations lived peacefully, all of that changed when the firenation atacked. Only the avatar, master of all four elements could stop them but when we needed him the most, he vanished. Me and my brother discovered a new avatar, an airbender named aang and even though his airbending skills where really good, he has a lot to learn before he's ready to save the world. He went through a lof of tragedies before he could defeat fire lord ozai...After the war was finally over, Zuko became the new firelord and Zuko, Mai, Aang, Katara, Sokka and Suki all start a new life after the war was over.
