One Hundred Years Later~
"I did everything he told me to do...!" Sokka whispered. Katara shook her head smirking.
"Like you could do better?" he snapped angrily, glaring at her. Katara rolled her eyes, and they continued walking through the snow, looking for some food. It was difficult with a war going on, because food was scarce.
"Sokka, what is that?" Katara said anxiously, pointing at a large iceberg. Suddenly, she took Sokka's boomerang and ran towards the thing. She hit it, and then she and her brother were suddenly blasted back by such force that they were a good twenty feet away. A blue light shot into the air, and then disappeared.
Katara ran towards the broken iceberg, and looked inside. A big pile of fur, a young boy, and a small girl were laying in the ice. The fur appeared to be breathing. Katara slid into the bowl-like structure and shook the boy slightly. His eyes opened and he suddenly grinned, and then it disappeared.
"Annchi!" He jumped up and ran over to the small girl, and her eyes fluttered open, but only slightly. If you weren't up close, you wouldn't be able to tell that she was even breathing.
"Aang?" She looked over at the other two, and her eyes closed again.
"She was just fine days ago!" Aang exclaimed violently. He picked her up from the ground and leaped onto the huge pile of fur. It groaned loudly and raised it's head, looking around in exhaustion.
"Take her back to our village, she can get well there," said Katara. She looked at Aang hopefully and he nodded.
"Climb onto Appa and lead the way," said Aang. "Yip, yip."
Appa rose from the ground, and began in the direction of the Southern Water Tribe, where he hoped his sister would get well. If she left him, he wouldn't be able to bear it. She was a part of him that he could not lose.
