The Dungeon Map

Sam's group finished a campaign that had been running since 2018. Same five people, every other Sunday, through two house moves and a pandemic. They wanted the final room tattooed as a proper old school graph paper dungeon map: the grid, the wall hatching, the little stair glyph, all of it. They brought in the actual DM's map, drawn in pencil on a battered sheet of quarter inch graph paper with a coffee ring in the corner. They wanted the coffee ring. Obviously we kept the coffee ring.

Grid patterns are a bit of a trap. A regular grid is the fastest way to make a tattoo look wrong, because our eyes are extremely good at spotting a broken repeating pattern, and forearms are curved cylinders that distort regular patterns automatically. Draw a perfect square grid, wrap it around a forearm, and the outer columns visibly stretch. The second issue is line density: hatched dungeon walls put a lot of parallel lines very close together, and closely spaced parallel fine lines are the classic recipe for a piece that turns into a solid grey block after a decade.

So I redrew the whole map on a cylinder in 3D first, which let me pre-distort the grid. The columns get subtly narrower toward the edges of the arm, so once it's wrapped it reads as square. That took me longer than the actual tattoo did, and I would happily do it again. For the wall hatching I dropped the line count by about a third from the original and opened up the gaps, so it'll still read as hatching in fifteen years instead of filling in. The grid lines themselves are deliberately lighter than the walls, one pass at low voltage, so there's a clear hierarchy and the whole thing doesn't flatten into one tone. The coffee ring is a soft grey wash in the corner. And yes, the door on the north wall that the party never opened is still there, because apparently that's an ongoing argument.
