What kinds of maps and game systems does Dyson's Dodecahedron cover?

Dyson's Dodecahedron (dysonlogos.blog) is a fantasy RPG map and dungeon-design blog whose content centers on hand-drawn maps for old-school and OSR-style play. The maps span dungeons, regional/overland maps, and full adventure locations, and the blog explicitly tags its work for systems including Dungeons & Dragons, Labyrinth Lord, and Old School Essentials (OSE). It also publishes maps originally drawn for official D&D products, such as Ghosts of Saltmarsh, alongside original text and releases.

Map types you'll find

The blog's posts are organized around several recurring map categories, visible in its own tagging:

• Dungeons — the classic underground complex, the format the site is best known for.
• Regional maps — overland and area maps, tagged "Regional" and "Regional Map."
• Adventure locations — self-contained sites built around a single map, such as the Isle of the Abbey release.
• Official D&D maps — maps the author drew for published Wizards of the Coast products, later re-released with original accompanying text.

A single post can carry multiple of these tags at once. The Isle of the Abbey entry, for example, is tagged both "Regional" and "Regional Map" while also being an adventure location.

Game systems and compatibility

The blog's own tags name the systems its content is aimed at:

Because the maps are system-agnostic drawings rather than stat blocks, the tags signal the style of play they suit — old-school, exploration-driven fantasy — more than a strict rules dependency. A dungeon map works with any of the listed systems; the tags tell you which audience the author is writing for.

Official maps and how they're released

Some content comes from professional work. The Isle of the Abbey map was drawn for Ghosts of Saltmarsh and is copyright Wizards of the Coast, but the text packaged with the blog release is original and unrelated to the published adventure's version.

These official-map releases follow a specific distribution pattern worth knowing before you go looking:

• A low-resolution sample of the map is available to everyone.
• High-resolution versions are limited to Patreon supporters at the Level 1 Adventurer tier and above, plus all Legacy Patrons, and to people who purchase the release through the Patreon storefront.
• These maps are not included in the Patreon-exclusive end-of-month PDF; they ship as their own separate PDF alongside it.
• They're released under the blog's Restricted Release License, intended for personal gaming use — distributing them outside your own sessions violates that agreement.

So if you see a map you want at full resolution, expect a paywall or storefront purchase rather than a free download. The free version is a preview, not the full asset.

What this means for you

If you run old-school fantasy games — D&D in its various editions, Labyrinth Lord, OSE, or anything in the OSR space — the blog's maps are built for exactly that style of exploration and dungeon-crawling play. If you specifically want the high-resolution files or the official-product maps, plan on a Patreon tier or a storefront purchase, and check the license terms before sharing anything with your group beyond the table.
