"Salt. Salt. Salt. and more Salt Long ago, the four nations lived together in harmony. Then, everything changed when the Salt Nation attacked. Only the Avatar, master of all four Salts, 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 Salt Bender named Johnson. And although his Salt Bending skills are great, he has a lot to learn before he's ready to save anyone. But I believe he can save the world."
