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 the Dwarven Folly that is Ruldroc Castle.

An exercise in pointless stonecraft, this castle sits abandoned and oft overrun by foul creatures. A dwarven folly – a structure built purely for the sake of building a structure – the castle cuts into and juts over a small canyon in the foothills of Tismar Summit.

When the dwarves left after building the folly, they locked the doors and forgot about it. To this day the front doors remain locked and require Voldrugg’s Key (or magic) to be opened – the current residents got in instead by climbing down on to the bridges over the small river canyon and eventually discovering the mechanisms that open the door on the upper level of the castle.

No one would care about the current residents of the folly if they hadn’t recently gathered a few competing tribes and raided a caravanserai where they looted and burned… and kidnapped the fourth son of Grand Duke Dietmar Stengel. The Grand Duke would really like his son back before they eat him.

The 1200 dpi versions of the map were drawn at a scale of 240 pixels per square and are 9,840 pixels (41 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 2,870 pixels wide or 5,740 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 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”).

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