Have built these recently, the idea being that we place these short wall sections round the edge of Quest rooms. Having made loads of little rock sections for the caverns set I thought that maybe the basic Quest rooms would benefit from a similar treatment.
So I made these 5 sections to see how they would look. Thought that they might give a more enclosed feeling without full walls. Also I can have some higher versions from which I can hang aras from to give the dungeon a more realistic feel.
