Book 1: Fearless
Chapter 7: Lose Yourself
Kayo was fuming.
"I have never been so humiliated in my life," he screamed. "How could the mere Avatar have gotten away like that?"
Azula just stood there. They were on an island somewhere in Lake Laogai. She did not like her new master, but she didn't want to get him mad at her, so she didn't say anything. He was so powerful. She hadn't liked him since the moment he interfered with her attempt to capture the Avatar. But she also knew that she couldn't beat him in a one on one fight. She would have to stick with him until he taught her enough so that she could defeat him.
When her thoughts returned to the present, Kayo was still raving about how he was supposed to be the most powerful being on the planet. It was true. Azula had never seen so much power come out of one person like when Kayo had shot the hillside with light. She was still trying to figure out if the light was a type of forgotten firebending technique or if it was a new kind of bending that could be taught to anyone. In either case, she intended to learn this new ability and destroy Kayo with it. Then she would get back to chasing the Avatar. Her only concern was that Zuko had disappeared. With him out on his own, she would have to worry about Zuko capturing the Avatar first, and if he broke Iroh out of Ba Sing Se, it might become difficult to capture the Avatar first.
Kayo was looking at her. She immediately left her private thoughts behind.
"So," he said, "shall we begin your training."
She bowed slightly and answered grudgingly, "Yes, Master."
"Very well then. First you must learn what the ability I am going to teach you is, and where it comes from. It is called lightbending. More precise then lightning, and far more powerful. Lightbending is not firebending, as you might have supposed. Light often emanates from fire, that that is not it's only source. Have you noticed how the Avatar glows in when he enters the Avatar state.
"Of course," she said, rolling her eyes.
"That is the kind of light that lightbending uses. Spiritual light. To master it you must give up something I suppose you probably think you can't give up."
"I can give anything I own up. No possessions are more valuable than power," she said.
He laughed at her. She didn't like it at all. No one had ever laughed at her and gotten away with it before. Her anger began to boil, but she suppressed it, remembering Kayo's power.
"That's not what I meant," he said when he finally stopped laughing. "You must give up something you didn't know you could give away. You probably think it is a permanent part of who you are."
She looked at him with a confused look on her face.
"You see, you must give up something that has been a part of you your entire life."
She still didn't get it and he began to laugh at her again. Once again the rage began to boil, but she suppressed it.
He stopped laughing and looked at her with a serious look on his face.
"You must give up your ability to firebend," he said.
I'm just going to leave it at that for right now. Hope this answers some questions about what Kayo is. As for who he is, the answer will come in time. Thanks for reading and please leave replies letting me know what you think.
