Water. Earth. Fire. Air. Long ago the four Nations lived together in harmony. Then, everything changed when the Nation attacked. Only the Avatar, master of all four elements could stop them but when the world needed him most....he vanished. A hundred years passed and my brother and I discovered the new Avatar, and 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.
