Every month we go through our back catalogue 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. This release goes back to 2014.

We don’t know why the ancients built so may underground structures (perhaps to remain out of the sight of the elves who ruled the lands) – and something about how they built them enabled them to survive for ages beyond what you would expect for stone structures in unstable land.

Regardless, over the ages since the end of their civilization, their ruins have been discovered by countless miners, diggers, spelunkers, and treasure hunters.

This particular set of ruins is partially collapsed and now links to a cave that is home to far too many bats for entry to be a sanitary or safe choice. But behind all that guano there’s a fairly intact set of ancient ruins, along with the odd artifacts that usually come with such. Occasionally a small artifact makes its way to the front of the cave with all the comings and goings of the bats, and maybe it will be enough to get the attention of some adventurers with the right equipment or magic to get past all that crap and the gasses it produces to find the ruins beyond.

The 1200 dpi version of the map is posted at a scale of 300 pixels per square and is 8,700 pixels (29 squares) wide. To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for 10′ squares) – so resizing it to either 2,030 pixels wide or 4,060 pixels wide, respectively.

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 600 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”).

Please note that the promotional version of this map (the one with the brown paper background) is not included in this commercial use license.
