Earth, Water, Fire, Air.
My mother used to tell me the legends about the old days, a time of peace when the Avatar kept the balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But everything changed when the Fire Nation attacked. Only the Avatar could master all four elements and enter the spirit world safely. But when the world needed him most, he vanished.
A hundred years passed and the new Avatar, Aang, was found in an iceberg. He and his friends heroically ended the Hundred Year War, transforming the Fire Nation colonies into the United Republic of Nations, a society where benders and non-benders from all over the world could live and thrive together in peace and harmony. They named the capital of this great land Republic City.
But fifty years later, the Fire Nation has threatened to reform, with the help of Fire Lord Zuko's grandson, Orion, who seems to have genetically inherited his great-grandfather's craze and bloodthirstiness. Only the Avatar, master of all four elements, can stop the Second Hundred Year War.
My name is Lily. I am the Avatar. And I am here to save the world.
