Water earth fire air. Long ago the four nations lived together in harmony. then, everything changed when the fire nation attacked. Only the avatar, master of all 4 elements could stop them. But when the world needed him he most, he vanished. 100 years passed and my brother and I discovered the new avatar, an airbender named aang, and although his airbending skills are great, he has a lot to learn before he’s ready to save anyone. but I believe, Aang can save the world.
