Free Maps

The main emphasis of my work is the production and dissemination of free maps from the Dyson’s Dodecahedron blog. At this time I release an average of two maps a week from the blog, free for personal use and reproduction including the use and modification of these maps for non-commercial use (such as non-commercially released adventures and campaign settings and so on). A huge variety of maps have been produced and released on the blog over the last nine years including dungeons, caverns, cities, towns, temples, inns & taverns, regional maps, and hundreds of dungeon geomorphs.

In addition, thanks to the patrons of my Patreon Campaign, a number of maps are released each month under a royalty-free and free-use commercial license allowing anyone to use, abuse, fold, spindle and manipulate these maps as they please for commercial projects.

I am not currently taking general commissions, although publishers are still free to contact me to see what I can squeeze into my schedule (especially for old-school styled projects).




A number of books and electronic zines have been released under my self-run publishing imprint, ZERO/barrier Productions. The best known of these are Dyson’s Delves volumes I & II and the Dyson’s Dodecahedron Zine (of which there are currently 8 issues available).
