But, when the world needed him most, he vanished. A hundred years passed and Dapplestream and her brother, Fishclaw, discovered the new Avatar, an AirClan warrior named Airclaw. And although his airbending skills are great, he has a lot to learn before he's ready to save anyone. But Dapplestream believes, Airclaw can save the world.
