Football. Tennis. Basketball. Tetherball.

Long ago, the four nations lived together in harmony. Then everything changed when the Basketball Nation attacked.

Only the True Athlete, master of all four sports, could stop them. But when the world needed him most, he vanished.

A hundred years passed and my brother and I discovered the new True Athlete, a Tetherball player named Aang, and although his Tetherball 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.
