Aang knew what he was doing, was wrong. He pushed those thoughts out of his head. He concentrated on the storm, then before he knew water was all around him. The avatar state pulled him in swallowing him. He started to form the water, but something snapped him out of the Avatar state and Aang drowned As he died, his life began to flash before his eyes. The images didn't stop at his drowning but continued on, he saw friends, a family, and so much more. He began to struggle, his last breath left his body.
Aang awakes in the spirit world, he turns and sees Avatar Ruko.
"Aang." Ruko says his face full of worry. "Welcome to the spirit world. "
Aang asks, "What's wrong?"
"Aang, you weren't supposed to die" He pauses, "The cycle has been reversed."
"What?" Aang stares confused. "Ruko that's not possible."
"Aang everything has changed."
100 years later
Zuko stands at the bow of the ship. Staring ahead, once again he had been plagued by dreams. Dreams of a young bald child fighting his father. He barely slept.
"Prince Zuko, where do you plan on going now?" Iroh asks.
"The southern water tribe" He says turning away. He did not know why the water tribe was important, but he knew that was where he needed to be.
