Aang.

Aang was flying on his bison Appa trying to find the rest of his friends. He had gotten separated from them when Azula and her friends showed up. To make matters worse, it seems like they had hired June to track them down. He had managed to drive June and her Shirshu away, but it was only a matter of time until June tracked them down again.

"Hey, Aang, have you seen anything yet," came Toph's voice. "I'm keeping my eye out for them, but I'm not having much luck."

Aang laughed. "Classic Toph, I know you're blind. Honestly, I'm surprised you're still making that joke now that t you turned 18."

"I know you're over a hundred years old, Aang, but don't start sounding like an old man," Toph said. "Any way have you found them yet?"

"I think I saw them going into that building over there," Aang said.

"What building and over where?" Toph asked sarcastically.

"We'll just head over there," Aang said as she brought Appa down. When they entered the building, Aang saw that the walls were full of books indicating that this was some kind of library.

"What kind of place is this, Aang?" Toph asked, a little worried.

"With all the books, it seems to be a library of some kind," Aang said.

"Not that. This place is strange," Toph said, worried.

"How so?"

"It's just that I really can sense things in here," Toph said, worried.

"Does that mean you're really blind?" Aang asked, worried.

"I can sense things that are in the room, but I can't sense anything beyond the walls," Toph said.

"I take it that you can't find our friends in here," Aang asked.

"I told you I can't sense anything. I'm not sure anyone else is even here," Toph said.

"Well, just stay close to me," Aang said.

They walked through the library; a book fell on Aang.

"Ha, haha. Aang, your luck is terrible today," Toph said.

"Yeah, I know," Aang said as he picked up the book. The title was "Li, Last of his People. But not his Kind." The book really intrigued Aang since he was in a similar situation. He wondered if this book could help him some way.

"Toph, do you mind if I flip through this book for a minute?" he asked.

"Just be quick about it," Toph said.
