"Water.
Earth.
Fire.
Air.
Long ago, the four nations lived together in harmony. Everything changed when the Fire Nation attacked.
Only the Avatar mastered all four element and only the Avatar's Advisor, a bender from legends, could master two. Only they could stop the ruthless firebenders. But when the world needed them most, they vanished. A hundred years have passed and the Fire Nation is nearing victory in the War.
Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving my brother and me to look after our tribe.
Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken. Even more believe that the Advisor was never born at all, nothing more than the tales of an Avatar passed.
But I haven't lost hope. I still believe that somehow, the Avatar and his Advisor will return to save the world."
In which the Avatar, his friend, and the world are reunited.
