IsoDungeon Forge

Computer-drawn isometric dungeons, three levels deep and joined by stairs, bridges, ladders and shafts. Pick a type, roll a seed for a new map and name, rename it if you like, and copy out the SVG. Pause the cursor over the Copy SVG button for instruction.

Saving a mapCopy SVG puts the whole drawing on your clipboard. Paste it into a text file saved as .svg, or into Inkscape or Illustrator. The fonts travel inside the file.

Reading the map

Each level is a cut slice of earth with its front walls removed. Numbered circles match the legend. Lettered diamonds mark where each way down begins and where it arrives on the level below.

Ways between levels

Each seed builds new connecting architecture: stairs with or without banisters, S-bends with landings, arched stone bridges, rickety rope bridges, ladders, ladder shafts and spiral stairs. Each one ends at an open arch, an oak door or a portcullis.

How it is inked

Every edge is redrawn with a slow bow, a wrist wobble, finger tremor and overshoot at the corners. Shaded faces get a grey wash and hatching; earth gets strata, stones and clustered hatch marks.

Names

Every new map gets a name built from the dungeon type: an adjective, a word for the place (crypt, barrow, delvings, fane and others), and a saint, a dwarf-hold, an elder god or a place-name. Type over it to use your own, or press New name.
