An old man with arrows tattooed on him was sitting, meditating. He was at the age of 212 years. Today was the day of Sozin's Comet. A monstrous comet that amplifies firebending a hundred fold. Today was the first day, of the war on the Avatar. The old man stood up and created an air spout. He swirled around preparing to be attacked by all sides. Great balls of fire bombarded the temple he inhabited. Great ships with Earthbenders, Waterbenders, Airbenders, and Firebenders prepared to invade. The Earthbenders shook the base of the temple with their mighty power. The Waterbenders ran up the path and attacked the old man. The man pulled water from a nearby fountain and used it as a whip to fight off the Waterbenders. Airbenders flew in on their gliders attacking the man. Firebenders that were launching fireballs at him started to scale the temple wall. The temple was recently built to help future Avatars learn from the place. A library full of elite bending techniques on all of the four elements but the first battle of the war of the Avatar ravaged the temple. The man fought valiantly, using his powers to avoid and evade. An air nomad philosophy to never kill a living creature is one that the man followed very seriously.
As a fireball came up and wiped him of the face of the earth, a little water tribe baby was born, in the North Pole. This girl was the Avatar. As the water tribe elders new that she was, the Avatar, they also knew that if she was to stop the war, she needed to be saved. They took the girl and hid her from the city. They told the people that the Avatar was executed as accordingly, and will be born into the Earth kingdom. As the word of the Earth kingdom Avatar spread, the real Avatar, grew up. Though Aang, the Avatar, was dead.
I didn't explain the story of Avatar because I am too lazy to ( ^ - ^ ) # I have a waffle.
