AT

After Avatar Roku’s death, the world waited for the next Avatar to bring balance. Instead, the Avatar vanished. Unknown to everyone, Avatar Aang had become trapped within an iceberg, but the world believed he had died. As the years passed, there was no sign of a new Avatar. Ten years became fifty, then one hundred. Without the Avatar, the Fire Nation grew stronger, the Hundred Year War spread across the world, and hope slowly disappeared.
