Fire and Aether

Overview

Water. Earth. Fire. Air. Aether.
My grandmother used to tell me stories about the old days--A time when the Avatar kept balance between the Water Tribe, Earth Kingdom, Fire Nation, Air Nomads, and the Aether Realm.
But that all changed when the Fire Nation attacked.
Only the Avatar mastered all five elements. Only she could stop the ruthless firebenders.
But when the world needed her most, she 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 me and my brother to look after our tribe.
Some people believe that the Avatar was never reborn into the Aether Realm and that the cycle is broken. But I haven't lost hope. I still believe that the Avatar will return to save the world...
