All Things Solo

I found this small dungeon crawl map / tiles set (PDF + images) in Drivethrurpg and it is currently free.
Images are high res so they need to be downscaled to be used in FGU.
It comes with a PDF book that explains what is what. But of course, it's not a FGU module.
You can use it as a Solo Dungeon Crawler with the rules from the PDF, or use the tiles in FGU Map Tool to create your own dungeon.

What's Included

Each FlexCrawl Theme Pack features:

• 12 FlexCrawl Tiles, each with dozens of dynamic content options, usable in infinite combination.
• 72 high-resolution Tile image files, usable to print out for personal use, reference during a game session, or import into a Virtual Tabletop (VTT) for personal use.
• Customized dynamic adventure content specific to this Theme.
• System-neutral rules specific to adventures using the Tiles in this Theme Pack.
