Jalia is an Airbender. She was actually best friends with Aang 100 years ago. But a week after he found out about him being the Avatar, he left. He left a note under her door and then he was never seen again. The monks knew he was okay, but she had to see him in order to believe them. So she set off on her sky bison to search for him. She searched for him for many months and she happened to be flying in a storm over the ocean when she finally saw him flying his sky bison in the storm. She barely caught up to him, and he was barely able to look at her before they were almost hit by lightning and fell into the water. There, Aang had gone into the Avatar state and somehow, so had she. They both formed a huge iceberg around the four of them and were safe for the next 100 years. While they were frozen in time, the world around them changed. The war had started and all their people were destroyed. Then they meet Sokka and Katara. They don't know what is in store for their futures.
