Last night, I created a new sub-level for my version of Castle Greyhawk, using the DungeonMorph dice from Inkwell Ideas.  I was a backer of their original Kickstarter in 2011, and remain quite fond of their geos dice, and of dungeon geomorphs in general!
Here’s the original geomorphs dice used for inspiration:

You’ll note that I largely ignored the caverns in the eastern half of the dice image, save for general sizing and some shape inspiration.
If you’re curious, full-sized versions of the images are at:
Enjoy, and stay safe amidst the covid-chaos!
