Every month we go through our back catalog of maps and the many patrons over on Patreons vote on which two should be re-released under the free commercial use license.

A warren of small chambers, passages, and natural caves, the Dark Caverns of Turr were once a set of dwarven mines of the famously unstable Darkshoe clan. But then one day the Darkshoe dwarves picked up and left, locking most of the doors behind them. In the years since, creatures have crawled up from the darker caves below and others have moved in from the surface, and the caverns now contain a veritable Gygaxian collection of creatures that try to live together.

There are three entrances into the warrens.

• The “front door” over to the far right of the map that leads into the original Darkshoe clan hall.
• The “back door” over to the left that leads into the deeper caves.
• The “stone stairs” very near the back door that lead down into the “glittering gallery” that come down from a secret cleft in the back of a small cave overhead.

This map is actually one I drew back in 2010 when running either my Labyrinth Lord or B/X D&D campaign that year. This photo doesn’t do it justice, but it is drawn in VERY light pencil on thin typewriter paper (without any backing grid), and was nearly impossible to scan and keep the details looking at all good. But now I’ve figured out how to get these old maps scanned and people liked the end result enough that it was requested for this month’s “release the Kraken”.

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 400 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”).
