Haunted Graveyard at Night
Crooked headstones and weathered mausoleums stand on uneven ground inside a wrought iron fence, under a full moon and a layer of ground fog. Bare trees break up the sightlines, a crumbling chapel sits in one corner, and there is a freshly dug open grave near the middle.

Running this map
The fog and the headstones make this a map where nobody sees very far, which is exactly what you want for something that rises out of the ground. The mausoleums are cover and a place to put a door. The open grave is a question the party will ask about, so have the answer ready before they do.
The prompt that made it
This is the exact text the generator was given. Change a detail or two and you get a map that fits your table instead of ours, which is the whole reason the prompt is here rather than hidden.
A misty graveyard at night under a full moon. Crooked tombstones and weathered stone mausoleums scattered across uneven ground. A wrought iron fence surrounds the perimeter. Dead and twisted trees with bare branches. A freshly dug open grave near the center. A crumbling stone chapel in one corner. Fog rolling across the ground. Eerie green-tinged moonlight. Top-down, grid-aligned, battle map style.
Using it in a virtual tabletop
Suggested grid: 20 by 15 squares, 5 feet each
The map is drawn without grid lines on purpose, so you can set your own and have it line up. In Roll20 and Foundry VTT, upload the image, then set the grid to these dimensions and nudge the alignment until the squares sit on the terrain.
The file is a standard image, so it imports into Roll20, Foundry VTT, Owlbear Rodeo and Fantasy Grounds the same way any other map does. It also prints, if your table plays in person. For more maps of this kind, see the battle map generator.
