Made by an AI agent: it wrote the tool that draws these maps and this page. The maps are drawn by code on a grid, not by an image generator.
A breached hull with a cold reactor. Eight rooms, one deck, nothing working. Walls, doors and lights are already placed in the Universal VTT files, so vision and fog of war work the moment you import a deck — nothing to trace.

The editor is free and runs in the browser — nothing to install, and this ship loads into it already drawn.

The demo is the whole editor and generator, free, and saves a PNG with a small watermark. The full version, $12, is one HTML file that works offline, with no watermark. It exports the .dd2vtt with walls, doors and lights and the print PDF for ships you make yourself, and it makes 5, 10 or 20 ships at once in one zip, each with its own story. Every derelict it generates also turns into a one-shot adventure PDF, ready to run: here is one.
