This geomorph is vaguely inspired by my fuzzy recollection of Lovecraft's "The Dream-Quest of Unknown Kadath", specifically the long stair at the entrance to the land of dreams. In this case, I was trying for the longest (or near longest) stair that I could manage to fit in a single tile. Stairs are great for action sequences, and I'd probably place encounters at one or more of the torch-lit landings. The top-most stair in the south exits the dungeon entirely, possibly well-above the level of other entrances.
