The Sinkhole Crypt

Climbing through some tiny caves, a young devout of the god of magic stumbled into a strange dungeon of metal, twisted and bent by the weight of rock upon it, and the untold ages it has sat down there. Exploring the strange depths the devout finally managed to make some sort of sense of one of the bizarre altars within… With a last prayer to their deity, they activated the machinery and promptly died in the massive blast of heat that followed.

But the heat burned not just within the structure, but even more intensely outside of it, producing a sinkhole in the solid rock above it. It took months for the rock to cool to a temperature where people could explore it, and it was immediately claimed by the church of the young explorer who created it. They explored the metal dungeons again, but there was no way to bring them back to life once more – the blast of heat that produced the sinkhole was the last gasp of these strange metal walls.

After their research was complete, the church built a crypt in the side of the sinkhole to commemorate the young devout (linking to the metal structures beneath), sealed it, and departed. Since then someone or something has shattered the door and reopened both structures. Exploring the lower structure is distinctly difficult, as the doors have no means of grasping them to swing them open, and the doors not marked with an arrow either slide sideways into the wall or up into the metal above. With their mechanisms dead, this requires the use of a knock spell in most cases.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 7,200 x 13,200 pixels (24 x 44 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 the image to 1,680 x 3,080 pixels or 3,360 x 6,160 pixels, respectively.
