Normally mines are far more extensive than these, but the majority of these mines were converted into more typical dwarven structures, leaving only the unobtainium mines on the northwest face of a large underground cave.
These mines are meant to be linked to another dwarven stronghold, perhaps part of the fallen dwarven fortress of Kuln (as hinted at in the Challenge of the Frog Idol).
These dwarven mines were drawn in two drafts (pencil then inked) on standard graph paper using a standard mechanical pencil and then micron pens. They were then scanned and image enhanced in photoshop.
The dwarven mines are free for your non-commercial use (as indicated on the copyright page) thanks to Gaelan D’costa, Udo Femi, Chris Blauwkamp, Shane Knysh and the other patrons of the Dodecahedron who support the site and these creations financially through my Patreon Campaign.
