The Spiral Sink – Map Set 2

We descend further into the “Spiral Sink” – a dungeon built around spiral stairs down a central shaft. The Sink has been modified multiple times by groups since it was built, and now it has fallen into decay from disuse. This is the second (and last) map in the set, detailing levels 4 through 7.

Level 4 is where the spiral tightens – the walls encroach in on the central column and beyond this point the stairs are set with the outside of the shaft on one side and the central column on the other. This level has three different rooms with shafts to lower levels. The left side has a small shaft that descends to a room on level 5, as well as the large shaft that spans from level 2 to level 6. On this level the large shaft has three alcoves – one for the doorway, and three hard to access ones with odd contents in them. The right side has a narrow shaft with a ladder that leads down to level 5 and then level 6.

On level 5, the large shaft chamber has a small chamber attached to it that has been used as a private study and research area by some… thing? who would levitate up and down the shaft. For mid-level play, this is a great place for a solitary mind flayer or similar creature to base its operations. Around the main shaft on this level, the alcoves contain sarcophagi again, a final level of ancient tombs (which appears to have been the original intent of the whole structure).

Level 6 is the bottom of the spiral shaft. The contents of this level are in disarray – broken furniture, lots of cobwebs, and debris that has fallen down from above. The base of the large shaft chamber is littered with debris, and is also the accessway to the stairs down to the lowest level.

Level 7 is accessed via stairs on level 6, or by climbing to the bottom of the central ladder. This level appears to have been mostly emptied of furnishings and other items of interest except for a stone table with six circular stone “stools” around it.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 10,800 x 10,800 pixels (36 x 36 squares). To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for the recommended 10′ squares) – so resizing it to either 2,520 x 2,520 or 5,040 x 5,040, respectively.
