Square Rooms

From the Introduction:

Beyond the doors of the dungeon lie its countless rooms, although with some passageways the transition from corridor to room and the other way around is not quite so clear. And although some of the rooms are sights to behold many more are rather plain, square or rectangular affairs with little to tell them apart from one another. Just like with the corridors the walls are built from neatly fitted stones and the floor is made of equally well crafted stone tiles.
