This is the eighth map in the Index Card Dungeon II set. This map attaches to the east side of Map 5 (The Tower Dungeons). No direct surface accesses exist to this map, just the cave on the west side to Map 5, and the ruined sewers and basements that lead to Map 9.
This area is comprised of several low-ceilinged twisting caves with uneven floors. The caves in turn link to much older ruins to the east – there used to be a city here that was razed and buried, and all that remains here are the ancient sewers which we’ll explore in the next map.
The dark pool in the middle of the map is fed by a small stream to the north and then flows into the old sewers. The pool itself is home to a number of blind cave fish, and the giant cave locusts that feed upon them.
The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 9,000 x 5,400 pixels (30 x 18 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 2,100 x 1,260 or 4,200 x 2,520, respectively.
