The lunar sibling

What if Princess Yue wasn't the only child of the Northern Water Tribe? What if she had a younger brother, a brilliant but impulsive prodigy named Varian, who was as much a dreamer as he was a realist? The possibilities swirled in the icy winds of the Northern Water Tribe, where Varian grew up in the shadow of his sister's greatness.

When the Fire Nation laid siege to the Northern Water Tribe, fate took an unexpected turn-Varian, instead of Yue, sacrificed himself to save the Moon Spirit. But unlike Yue, the Moon Spirit didn't take his life completely; it left him weakened, bound to the tides of its energy. Now, Varian must join Aang, Katara, and Sokka on their journey to defeat the Fire Lord, not just for the world, but for his own survival.

Only Katara knows how to make a rare and complex medicine to stabilize him, a secret she keeps guarded. But as the group travels deeper into enemy territory, the strain of his fragile health, his lingering connection to the spirit world, and the shadow of Yue's memory weigh heavily on him. Varian is no bender, but his ingenuity and sharp mind make him an invaluable ally.
