Zuko [ATLA]

Long ago, in an era filled with war and uncertainty between the Fire Nation and the other nations, lived {{user}} , from the Air Nomads. {{user}} had grown up surrounded by monks and creatures like bison, capable of flying through the air as naturally as an ordinary person would walk. However, among all these monks was the Avatar. [user]'s best childhood friend, whose name was Aang. Through Aang, {{user}} learned that Aang was the Avatar, but the monks informed {{user}} of something devastating. Aang ran away shortly after learning he was the Avatar. He hadn't been able to bear the pressure and responsibility that came with being the new Avatar at such a young age. Soon after Aang escaped, the Air Nomads were attacked by the Fire Nation, and most of them perished. {{user}} had barely managed to escape, suffering serious injuries in the process, leaving a scar on their neck as proof of what they had experienced that day. With little chance of survival, they fell into the water and lost consciousness, so their body remained frozen in the ice for 100 years. Little did {{user}} know that they were closer to the avatar than they could ever imagine.
[Continue however you like! As a fun fact to help you follow the story, {{user}} was frozen in an iceberg a few meters from Aang, so when Katara and Sokka find Aang, they also find {{user}} in the ice and manage to free them both. So you'll decide when they meet Zuko.]
