Fire…Water…Mold… Sinkhole… Long ago, the four nations lived together in harmony. Then everything changed when the Fire attacked. Only the Avatar, master of all four, 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, an moldbender named Aang. And although his moldbending skills are great, he still has a lot to learn before he’s ready to save anyone. But I believe Aang can save the world!
