Avatar and The Dark Avatar

Book 1: Water

Water. Earth. Fire. Air. My grandmother used to tell me stories about the old days: a time of peace when the Avatar and the Dark Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation and Air Nomads. But that all changed when the Fire Nation attacked with the Dark Avatar on their side. Only the Avatar mastered all four elements; only he could stop the ruthless firebenders and The Dark Avatar. But when the world needed him most, he vanished and not long after so did the Dark Avatar.

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 Air Nomads and that the cycle is broken and somehow when the Dark Avatar returns they will take over, but I haven't lost hope. I still believe that, somehow, the Avatar will return to guide the Dark Avatar in the right path and that they both will save the world.
