Once the world was divided into four different nations, each were named after the four key elements. The Air Nation, the Earth Nation, the Water Nation, and the Fire Nation. The Air Nation was known for being calm and independent as were its people, the Earth Nation known for being a main source of life and controlling over its surroundings, as was the Earth. People of the Water Nation were known to be kind and compassionate, but just as water can be kind, it can turn cold and betray you if you betrayed the kind Water Tribe dwellers. The Water Nation consists of two tribes, the North and the South. Each on opposite poles of the Earth. As for the Fire Nation, they were known for anger, hate, destruction, honor, and power. The fire of which they were named after.
All was harmonious until the Fire Nation attacked the other nations, sending all the nations into a shattering war upon each other. The Fire Lord, Lord Ozai, has led this global war for the past century. Even sending his own son into the battle for domination. Prince Zuko was exiled from his own beloved Fire Nation until the war had succeeded in the Fire Nations' global domination of the other elements. To win back his honor and his home, Prince Zuko would not stop at anything to fulfill his fathers' wishes.
