I'll probably change my mind about things once it's far enough along to be really confusing, but I'm starting out with some conventions. The space between level floors is about 15 feet. Floor-to-ceiling distance on any given level, then, is typically in the 8-12 foot range, though see below for exceptions. Most of the dungeon is completely enclosed underground, so it's pitch dark unless delvers bring light with them unless otherwise noted. Some cartographic conventions are represented here:
- The dark hatching represents the solid interior of the cave. It's rock.
- No background indicates a space with no floor at that level, or possibly no floor and no ceiling; see explanatory text for the level for details. This may be a space like a long vertical mine shaft or the upper or middle parts of very large underground chambers.
- Lightly stippled areas are sandy unfinished floors, which predominate both inside and outside the dungeon. There is rock underneath a hand's breadth of sand and pebbles.
- Gridded areas are paved with stone or ceramic title.
- High floor areas are spots where the uneven surface of the cave floor rises 2-4 feet above the "floor" surface, high enough to be an obstacle or, carefully used as cover.
