ATLA AU

The four nations are restless. The Shadow Dragons, an elite and terrifying group of soldiers are on their way to world domination. Their master, The Dragon King, is a man bent on creating a world where the strong thrive and the weak perish. The world needs the Avatar, but the location of the newest Avatar is unknown.

Eighteen-year-old Pan believed that her life in the small fishing village where she lived with her grandparents was safe. When the Shadow Dragons suddenly show up at her village, her world is turned upside down. Pan's only way of escaping is with Trunks, a powerful Firebender that had arrived in the village earlier that day.

Although Trunks' mood changes from day to day, he protects Pan as they make their way to the Northern Water Tribe before The Winter Solstice happens. During their journey, something stirs between them, and Pan can't help but keep thinking she had met Trunks before. As the two of them grow closer to the North Pole, their encounters with the Shadow Dragons increase as The Solstice grows near. On that night, Pan discovers a secret about herself and the Avatar's presence is revealed to the world.
