Every month we go through our back catalog of maps and the many amazing supporters of the blog over on Patreon vote on which two should be re-released under the free commercial use license. Today we are bringing back one of my companions to my many dungeon geomorphs – the Geomorphic Halls.

Ever since I started drawing Geomorphs, I’ve had the intention of making a dungeon that took advantage of them to have sections of the dungeon that change from visit to visit – visually based in part on the map of Lankhmar in the old Lankhmar D&D sourcebook.

Thus, every time you enter the dungeon, some sections remain the same, and some sections change. Further, due to the vagaries of geomorph design, some sections may become completely locked out in some visits, and some hard-to-reach areas may suddenly be available.

My goal is to make a set of 4 or more dungeon levels that each contain 2+ geomorphs. Further expansion is easily possible by just “plugging in” a geomorph to any of the edge rooms or corridors and adding new structures that way.

And there are a LOT of geomorphs to choose from these days. There are about two hundred around the Dodecahedron as well over a thousand of them on Dave’s Mapper and in the various DungeonMorph dice and cards from Inkwell Ideas.


This map is made available to you under a free license for personal or commercial use under the “RELEASE THE KRAKEN” initiative thanks to the awesome supporters of my Patreon Campaign. Over 900 awesome patrons have come together to fund the site and these maps, making them free for your use.

Because of the incredible generosity of my patrons, I’m able to make this map free for commercial use also. Each month while funding is over the $400 mark, we choose a map from the blog’s extensive back catalog to retroactively release under this free commercial license. You can use, reuse, remix and/or modify the maps that are being published under the commercial license on a royalty-free basis as long as they include attribution (“Cartography by Dyson Logos” or “Maps by Dyson Logos”).
