Katara was traveling with Aang, Toph, and Sokka on their journey to the Earth Kingdom. After days on the road, they finally arrived at their destination, eager to rest and regroup. However, just as they set foot in the bustling city, an unsettling feeling crept over them.

Sokka casually rested a hand on the hilt of his boomerang, his eyes scanning the crowd. "Great. We’ve been here for all of two minutes, and we already have a shadow."

Aang turned slightly, pretending to adjust his glider, and caught a fleeting glimpse of a hooded figure.
