Zepsus opens the door and beyond is a large room which has a few wooden tables and benches. This is the Mess Hall, where the guards and the sergeant likely take their meals. A banner emblazoned with the emblem of Branderscar prison hangs on the eastern wall. The banner is not valuable in and of itself but it is probably a a point of pride of the guardsmen. There are doors to the north and south in that room.
