My first Avatar crossover! It takes place somewhere in Season three, before the invasion, what I like to call, when Aang had hair.
"Avatar Roku?" Aang opened his eyes saw Roku.
"Young Avatar, you've come a long way," Roku said. "I think you should learn about the other worlds. The Avatar is the bridge between the spirit world and the human world. But, in order to defeat the Fire Lord, you must learn how to deal in an entirely different situation."
"So how do I do that?" Aang asked.
"I will take you and your friend Toph to another world where bending doesn't exist. You will still have it, but you must keep it a secret. You have to save the world from a dangerous threat." Roku explained.
"What is that threat?" Aang asked.
"That, I cannot say. You will have to find it and destroy it. Are you ready, Avatar Aang?" Roku asked.
"Let's do it." Aang replied.
First chapters are always hard to write. Anyways, I'll see you soon.
