The Halls of the Violet Sorcerer extend deep into Montauppes Mountain – with the main entrance along Stonerich Pass right before Gravel Bend (and the secret entrance being much further along Stonerich Pass). The paired entry doors have long been reduced to one sealed stone portal, the other buried under rubble and the weight of the mountain above it. Inside, the chambers are arranged in small clusters with extensive halls between them.

I’ve left the exact length of the passages up to the end user wherever the passages are “broken” with a letter (A, B, or C). Each of these letters can be a different distance of the DM’s choice – A determines how far the east and west sides are from each other, B determines the depth to the Great Hall and associated structures (including the secret entrance), and C determines how much further beyond the Great Hall one must travel to reach the furthest chambers of the Halls, and the Violet Sorcerer’s domain.

This map begs to be a classic D&D “puzzle / funhouse dungeon” with the various chambers each having their own minor mysteries to ponder, weird effects (what’s in the mist? what are the chambers beyond the cistern for? what’s with the repeating octagonal rooms?), or bizarre denizens that survive here via magic instead of feeding themselves.

Finally we have the domain of the Violet Sorcerer. This final chamber (in the middle of the top of the map) defies gravity and common sense, except where it doesn’t. The magics of the Violet Sorcerer have trapped them beyond the reach of common physics, and the gravity-defying stairs and the massive open pit that extends to unknown depths are here to remind those who visit that physics has taken at least a temporary vacation.

Because the final room is so specifically weird, I’ve also included versions of the dungeon (below) that doesn’t have the weird physics in play and remains a typical final dungeon room instead.

Yeah… I realized on posting this that the gridless maps have a tiny bit of grid that I forgot. But perfection is the enemy of done.

There is also some geometric trickery that should be addressed regarding slope angles and depths in the secret passage on the right side of the map. I’ve addressed these concerns in their own post.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 12,900 x 16,500 pixels in size (43 x 55 squares). To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for the recommended 10′ squares) – so resizing it to either 3,010 x 3,850 or 6,020 x 7,700 pixels, respectively.
