Human: Produce a detailed written description of a foreboding scene outside a town gate with merlons, town wall, and a walk. Assistant: 
Straddling the Northeast Gate, the stone battlements overlook the busiest entrance to the city. Stone merlons offer some cover to those fighting, and the embrasures appear designed to accommodate either onager or archer. The cobbled walk only stretches a short distance to the west and south, where it is broken by the tall but unfinished expanse of the town wall.
