At the Northern Water Tribe the siege continued. Four fireballs streaked. The fireballs struck various locations. At the Spirit Oasis where Appa was presiding by the pond. The two koi fish, the Moon and Ocean Spirits, swam in their usual circular pattern.

"I can't believe I lost him." Katara said sorrowfully.

Sokka stood beside Katara, who was kneeling on the ground.

"You did everything you could, and now we need to do everything we can to get him back." Sokka said. Katara looked up at her brother, tears in her eyes. "Zuko can't have gotten far. We'll find him. Aang's gonna be fine."

"Okay." Katara got up. Momo remained motionless on the ground. Katara mounted the bison. "It's all right. You stay here, Momo, in case Aang comes back."

"Yip, yip." Sokka said.

Appa took off, heading upward to a location above the oasis, a vast frozen tundra where a blizzard was raging. The icy terrain of the tundra stretched out below them as the bison progressed. A path was visible in the snow where someone had clearly been trudging along.

Zuko was plodding through the snow, his face partially covered to protect him from the cold, Aang slung across his back. Aang was unconscious, his tattooed arrows glowing.

Khione landed in a flash of scale and began to advance behind them.

Aang was sitting in a meditating position on a small wooden platform in an unknown location in the Spirit World. His surroundings were not that of the icy tundra, but a mystical swamp dotted with trees. A large white bird of some sort flew past. Aang stood and began wandering about. A figure in the distance was sitting beneath a simple wooden entranceway. The figure was uttering the sound "Ohm". Aang turned his head in the direction of the sound and began making his way toward the figure. The figure was a monkey-like creature; Aang approached him.

"Hello? I'm sorry to disturb you. I just really need to find the Moon and the Ocean Spirits." Aang said.

"Go. Away." The Baboon Spirit opened one eye. "You're still here?"

"Yes, I need -" Aang said.

The baboon spirit shut his eyes tightly. He spoke louder, trying to distract himself. "Ohm!" A firefly flew past; pointed at the insect. "Perhaps that thing will help you. Chase it." Aang ran after it. The mystical monkey kept his eyes shut for a second more before opening one to confirm Aang's departure. He shook his head and breathed a sigh of relief. "Finally."

Aang chased the insect throughout the swamp and up a tree. He leapt up and managed to grasp hold of it and was delighted in doing so. He landed on a tree branch which instantly shriveled up and disappeared entirely, causing him to fall. Aang was alarmed and fell into the water. Aang was shown lying on his back in the water, the firefly having escaped his grip. It flew away as he tried to reach it again.

"Come back!" Aang said.

He stood up. He was looking down at the water, when Roku suddenly appeared before Aang in a reflection in the water.

"Hello, Aang." Roku said.

Aang Looked at him; surprised. "Roku!"

Zuko continued his trek through the icy tundra. He stepped on ice that began cracking beneath his feet; his eyes widened in surprise at thisThe ice begins to splinter and cave in. He was on high alert as he began running. He raced through the snow. The ice caving in threw him off-balance. He was about to fall in along with Aang when two strong hands caught him.

Khione held the two of them and helped Zuko up. He pointed to a cave off in the distance.

"Shelter." Zuko explained.

Zuko dragged Aang into the cave and tied him up. Khione sat down and lit a campfire with Firebending.
