The Spiral Sink – Map Set 1

The remains of a low stone structure perches on the edge of a deep shaft. Spiral stairs descend as the shaft gradually becomes narrower. The “Spiral Sink” has been modified multiple times by groups since it was built, and now it has fallen into decay from disuse.

The first level of stairs circles the open pit, with a wide step and an accompanying alcove every 45 degrees around the route. Once we enter the second loop, the alcoves continue, except that the alcoves to the North, South, and East are each an entrance into the structures built behind the walls of the circular shaft. As is the trope, a section of the stairs has fallen away here, making it so most will have to travel through these side passages in order to continue their descent unless they have brought rappelling gear or any number of flying or levitation magics.

At the end of the internal structures on this level there is an open chamber that descends down to level 6, with ledges on each level between.

Level 3 brings us a change in the basic geometry of the structure – a ramp leads across from the stairs to the flat top of a 30 foot wide column that stretches down through the middle of the spiral – on lower levels, the spiral tightens and is effectively “pinned” between the pillar and the walls of the shaft. In the centre of the column is a ladder that extends down to the base of the spiral on level 6.

This level is dedicated to a series of four large tombs. The last of these tombs is (oddly) completely empty, while the others each contain stone sarcophagi. A secret chamber can be reached through a secret panel in the bottom of one sarcophagus, or a secret door in the wall of the next tomb down the spiral.

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.
