100 years ago, four nations lived together in harmony and peace. Then, everything changed when the Fire Nation attacked. Only the avatar, master of all four elements, could stop them. But when the world needed him most, he vanished. A new Avatar has been discovered, an 12-year old air-bender named Aang.
One of the four major nations, the Air Nomads were wanderers by definition, but had four air temples, one at each corner of the globe, hidden away atop mountain ranges and under cliffs, in the northern Earth Kingdom and on three remote islands.
During the Hundred Years War the Air Nation was allied with the Earth and Water Nations to fight Fire Lord Sozin and his Fire Nation. Fire Lord Ozai, hungry for power and the prosperity he believed the Fire Nation could bring, launched an attack to wipe out the Air Nomads and take over the Earth Kingdom. Avatar Roku, once a trusted friend of the Fire Lord, disappeared, leaving the world without a bridge between to the Spirits.
The Air Nomads were a peaceful race who were wiped out by the Fire Nation. They lived in large temples and traveled the world on flying bison. They were the most spiritual of all the cultures and lived in harmony with nature. They also were fun-loving and had a strong sense of humor.
The Air Nomads were the victims of genocide at the hands of the Fire Nation. Ironically, the sole known survivor of the massacre was the very person the Fire Nation sought to kill in its quest for supremacy: the twelve-year-old airbender and Avatar, Aang, who had run away from the Southern Air Temple shortly before the Hundred Year War began and became trapped in suspended animation in a globe of ice along with his lifetime friend, Appa. One hundred years later, he was awakened and released by Katara and Sokka, who helped him succeed in his quest to restore balance and peace to the warring nations.
