"Maybe Torrens was discovered? I'll go ahead and see what's happening." Narza calls out to Athinar as she slips through the sturdy wooden palisade walls and floats off toward the rising smoke in the midst of the town. Flying high into the sky, she is able to make out columns of smoke rising from a central building in the town, and smaller fires in the vicinity, with small figures streaming out of the center building. If these were the guards that her groups was supposed to assassinate, it wouldn't do to have them spreading out across the city. 

The shortest path between two points was a line. Unobstructed by any obstacles, Narza went from street to street and alley to alley, forming thick walls of us to block off the guards. While she seemingly placed the walls at random around the guardhouse, she left the street leading to Athinar's gate clear, with all offshoots sealed off. She hoped that with a street clear, the guards would just flock down that street instead of trying to break down walls.
