Hey guys! So this is my first avatar fanfiction that isn't a short story, it is slightly AU, but I hope you enjoy it anyways! It is hard core Kataang, not a first, but there will be! I promise! The first few chapters are just the mere foundation of this story. It starts off when Aang runs away, but there is a change in plans. It begins when Aang was 12 and the Fire Nation attacks for the first time. All characters are there though like Katara, Sokka and so on. Please Review if you want more!

It started off as a sunny day, but not all nice days end that way. The avatar, Aang, just found out that the monks want to separate him and Gyatso and he will be moving to another temple. He never really liked the older monks. Even though they favored him more, they were harder on him. He always wondered why, but once they told Aang he was the avatar. Monk Gyatso was the only one who kept reminding him to have fun and just relax sometimes. The other monks just wanted him to be the avatar and attend to his duties and not think of Aang as a normal kid. They already ruined his friendship with the other airbenders since they found about Aang being the avatar and now they are going to take away the only person he ever loved as a parent. How dare they! Aang thought.

He was beyond mad, but was also frightened. They had the power to do it; he couldn't handle all this responsibility at his young age though. He finds out he is the avatar, he has to stop a war before happening, and now he has to move to another air temple. His whole life is changing and he didn't like it one bit. He liked it the way it was, he was the simple airbender monk who had friends and had no responsibilities to the world. It scared him; it would scare anyone at that age.

He looked at his room, knowing that this maybe the last time he sees it for a while. He places his letter for his friend Monk Gyatso. Tears are running down his face and he takes his glider and flies out of his room to find Appa, his flying bison.

He finds him at a corner of the temple where he was sleeping. No one was around him. Appa heard Aang coming and he slowly raised his head and tilted it a bit, for concern. Appa gently licked the airbender, making him laugh a bit. Aang loved his fluffy friend.

"Hey there boy," Aang said rubbing his hand on the bison's arrow. "We are leaving this place, at least for a while so I can sort things out."

Appa did what his friend said to do. He took off into the rainy skies. Aang thought it was just rain, nothing more, but boy was he wrong. Aang wished he never left the air temple. The clear day turned into a callous storm. It was awful and like nothing he has ever seen.

"Ahhhhh!" Aang screamed as he plunged to the deep waters of the ocean with Appa. He couldn't breathe for a minute or so. He was starting to go unconscious. Suddenly he was in a state that he couldn't explain. It was strange feeling which he has never experienced. The next thing he knew though was he was out of the ocean and he was weak. He felt completely drained and had absolutely no energy left.

"Ugh," the avatar groaned. He looked up to see the storm that almost caused his death was calmer and not much rain, it was more of a mere drizzle and the sun was shining out of the gray clouds.

"I guess that's a sign saying we should go back, don't you think boy?" Aang asked Appa and he replied with a roar agreeing. They now headed to the direction of home.

So there is chapter 1. Short yes, but that is how the first few chapters are. I will make them longer as I go. Please review and tell me how I did! I really want to know you guy's thoughts. Review as you always should.
