(A/N My original story got deleted for no apparent reason, so I am doing it over. Again. Please review! I lost those too! Flashback

5-year-old Prince Zuko and his sister, 4-year-old Princess Rayna were running down the halls of the royal palace screaming and laughing until they ran into a servant carrying a large armful of cloths, bowling the servant over. The children just laughed and ran away as fast as possible. Soon they're father, Fire Lord Ozai, stopped and punished them.

"But father, we were just playing," squeaked a tiny Prince Zuko.

"Please don't hurt us," cried a teary eyed Princess Rayna.

"Go to the servant's quarters, I want you to clean and act like a servant for three hours," boomed Ozai.

"Yes, father," said the siblings in unison and trudged off to the servant's quarters.

End Flashback

Prince Zuko remembered Rayna, like her brother, having long, jet-black hair. Her's, unlike her brother, had streaks a blood red, while tied up in a ponytail.

Prince Zuko leaned over the railing of his ship and sighed.

That same year, another girl had been born. By the time Prince Zuko was eight and Princess Rayna seven, the baby, Katrina, was three. Prince Zuko did not see much of Katrina, for he was constantly training.

After he was banished, he got to say good-bye before he left. Katrina, being only ten, did not understand why her thirteen-year-old sister was sobbing uncontrollably. She did not understand why her big brother had a scar and why he was leaving.

Prince Zuko sighed again. He would do anything to see his sisters again.

Appa was flying over an island when the gang decided to land. They had left Momo and Appa in the forest while they walked to the nearest town. (It was an Earth Kingdom town)

Suddenly Katara stopped and gasped. In front of her lay an unconscious girl with long black hair streaked with gold. She wore a long black cloak that covered the cloths she wore underneath, so they could not tell which nation she was from. She bleeding profusely and there were scorch marks all around her. She looked to be about Aang's age.

"So then the chicken started eating ME," Sokka rambled on.

"Sokka, would you please stop rambling on about a stupid dream you had and look in front of you!" snapped Katara. Sokka gasped and knelt down to check her pulse.

"She's still alive. Katara, get some bandages. Aang, get water," commanded Sokka.

"It's going to be all right," he told the unconscious girl. He took off her cloak to see red cloths. Partly to blood and partly because she was from the Fire Nation. She had cuts and burns all over her but the worst one was a dagger hilt sticking out of her left shoulder, right above her…heart.

Sokka quickly pulled out the dagger even though it only made the cut bleed more profusely. He picked her up bridal style and carried her back to camp, despite the fact she was Fire Nation.

When he got back to camp, Katara said, "Okay guys, go around Appa. I have to bandage her up, which requires partially stripping her." Both boys turned a beet red and walked around Appa.

A few hours later, Katara had finished and the gang was setting up camp when they heard someone stirring. They looked at each other then ran up Appa's tail where the girl lay. "Rayna!" she cried her golden eyes shooting open.

"Rayna? Do you mean Princess Rayna?" asked Katara gently.

"Who are you? Where am I?" asked the stranger.

"I'm Katara, that's Sokka, and that's Aang, the Avatar," stated Katara.

"The Avatar?" asked the girl.

"Yes," said Aang hesitantly. "Now, who are you?"

"My name is Kathryn, "she said. "Please, where is my brother? I have been looking for him for seven weeks."

"What is his name?" asked Sokka.

"Zach," answered Kathryn.

"We haven't seen him, but maybe if you travel with us, we will see him," said Katara.

"Ok," said Kathryn, brightening.

Prince Zuko stiffened. He had just heard someone call out, "Rayna!" his sister's name. The voice sounded like Katrina's. He was probably just hearing things. Again. But non-the-less, he was curious.

There's the first chapter. I hope you guys like it. Please Review!
