assistant
The river wall's inner walkway ends at a door into the southwest tower, propped open by an overturned barrel. The sides of the tower, smoothly joined blocks of granite, rise straight up from the water, offering no way for intruders to slip into town without passing through the scrutiny of the guards. Overhead a stone bridge arcs between the roofs of the two towers, connecting them and reinforcing the structures.
