Water, Earth, Fire, and Air. The four elements of the world. There was four nations. Each one named after their element but one nation wanted to be in power over all. The fire Nation was stronger and had more weapons but there is one person who could fight against them. The Avatar But was there another? They tried to keep it a secret but there was a scroll that came out of nowhere. It said a child that will be born of both fire and water will be you helper or your doom. Many people looked for a young fire nation boy. I fortunately he was no where to be found. disclaimer I don't own the characters or the pics unless I said I did or if you know they aren't actually apart of the anime.
