Avatar Roku was emerging from behind a small wall of fire, and was speaking to Aang in a dream.

"Aang, it's time you learn of my history with Fire Lord Sozin." Roku said. "You need to understand how the war began, if you want to know how to end it. Meet me on my home island on the day of the summer solstice."

Aang was asleep, and rolled over on his side.

Aang Talked in his sleep. "Okay, Roku."

Meanwhile, Kuri was watching Zuko in the flames of their campfire, and noticed as he stirred and woke up.

Zuko was asleep as well, as sounds of footsteps woke him up, and he rushed to the hall to investigate. He opened the door, and saw a cloaked individual walk down the hall and disappear. Zuko began to go after the individual, but noticed a scroll lying on the floor. A surprised Zuko picked up the scroll and read it.

Zuko Read the scroll. "You need to know the story of your great-grandfather's demise. It will reveal your own destiny." . He closed the scroll, and stared down the hallway.

Zuko looked into a basin of water. "Kuri...should I?"

Kuri nodded in the pool of water. Zuko looked at the scroll again.

"Alright."

Zuko was still standing outside his bedroom.

It was the next day in a blue, cloud filled sky. A very large cloud moved quickly forward. Inside of the cloud, Aang, standing on Appa's back, bent the elements around the bison to create a cloud, to camouflage. Kuri, Katara and Sokka looked over Appa's saddle for a better look.

"There it is. That's Roku's home." Aang said.

Appa landed. Team Avatar descended from Appa.

Kuri was Confused. "But, there's nothing here."

Toph jumped from Appa's saddle, as her feet touched the ground.

"Yes, there is. An entire village, hundreds of houses ..." A strong breeze moved a layer of ash along the ground, brushing past their feet. "all completely buried in ash."

Kuri gazed into the fire again, seeing Zuko in a hall of paintings.

Zuko was in a hall, full of paintings of previous Fire Lords. Zuko stood before one of the portraits, as Azula passed by Zuko.

"It's never too early for a sitting with the court painter, Zuko. Make sure he gets your good side." Azula said.

"Wait, I need to ask you something." Zuko said. Azula stopped walking. "What do you remember about our great-grandfather's history?"

Azula sighed. "Oh, Zuko, it's so strange how your mind works." Azula began to tell Zuko about Sozin's history. "Fire Lord Sozin began the war, of course. He spent his early years secretly preparing for it. He was as patient as he was clever. He famously waited for the comet, later renamed Sozin's Comet, and used its power to launch his full-scale invasion of the world. In the end, he died a very old and successful man."

"But how did he die?" Zuko asked.

Azula Turned toward Zuko. "Didn't you pay any attention in school, Zuko? He died peacefully, in his sleep." Azula walked away. "He was ancient."

Zuko stared, frustrated.

On Roku's island, Team Avatar was sitting on the tip of a hardened wave of lava. Aang was facing the ocean, and was meditating. His arrows glowed, and he was sitting on a mountain top, surrounded by clouds, in the Spirit World. Fang, who was carrying Roku, flew near him, as he stood up, and Roku smiled at Aang.

Zuko was in his room, lying on his back on his bed. He rolled over on his side and stared at the scroll. He picked it up and read it to himself again.

"I have to know. Just like Kuri told me." Zuko said. "What does it mean?"

Annoyed, he tossed the scroll aside, as it landed on a lantern. The light from the lantern shone through the parchment, and it revealed a secret message on the scroll. Zuko gasped and grabbed the scroll from atop the lantern, and read the secret message aloud.

"The Fire Sages keep the secret history in the Dragonbone Catacombs." Zuko read.

Zuko finished reading the secret message. Zuko quickly turned to leave.

Later Zuko was in a dark temple. A Fire Sage walked through a courtyard, and stopped over a large medallion fashioned in the shape of a flower in the middle of the courtyard. He crouched low, and delivered a blast of fire into the center of the medallion. It began to open a hidden passage, under the courtyard of the temple. The Sage went into the passage through the steps. Zuko hid and waited behind a pillar. When no one was around, Zuko went to the secret passage, and bent a blast of fire into the medallion. The passage opened, and a spiral staircase was revealed along with a very large secret chamber. Zuko travelled through the chamber and down a hall lined with bones of dragons, all lined up along the walls of the hall. He came to an ornate door with a metal sculpture of Fire Lord Sozin on it. The chest of the sculpture has a Fire Nation emblem. Zuko placed his left hand over the emblem, and bent a fire blast. The fire filled the door, and came out from the statue's eyes, nose and mouth. Zuko entered the room, pulled his cloak from his head, and raised his lantern to look around the dark chamber, and saw that the room was filled with artifacts and various vessels. A large statue of a dragon sat in the middle of the room. Under the dragon's head, Zuko found Fire Lord Sozin's history.

"The final testimony of Fire Lord Sozin."
