For the final lair, the volcanic Womb of Ashes, I wanted to have some sigils engraved in the floor where the final ritual is being performed by all the covens united as a Grand Coven of 13: the Drowned Sisters' Grotto (sea hags), the Withering Glade (forest hags), the Miremothers' Den (swamp hags), the Frostmaidens' Cradle (alpine hags), and the Arch-hag at the Womb of Ashes. (Plus, it gives me an excuse to once again use the Marine Dungeons brass inlay that I love so much.)

I had previously discovered that some of the varicolor symbols used in CA15 Heraldic Symbols (2008) can be set to the magenta color to work as an inlay. I was delighted to discover that some (not all, but some) of the vector symbols from the overland map sets could also be exploded and turned magenta to do the same.

So...here are my sigils for each coven. The Forest Hags' was the easiest -- it comes exactly as is from the Marine Dungeons annual. Originally I was going to use the symbol of the tree without the runed circle, but then I realized that the runed circle could tie them all together and strengthen a visual similarity. The shell for the Sea Hags' symbol also comes from Marine Dungeons. The snake for the Swamp Hags' sigil comes from CA15. The water waves, swamp grasses, mountains, and volcano all come from CC3 Vector BW overland style that comes with CC3. The fire symbols were ones I made for one of the Trial of the Elements map in the Atlas. I couldn't find snowflake images that I liked, so I designed those ones myself specifically for this.

I thought I was going to have to draw a lot of stuff myself, which is totally not my forte. Really delighted to find that some of the vector images could work for this.

Started to work on the underground interiors, including experimenting with creating places for the captives, who are encased in ice.

For those prisons, I experimented with putting the frozen water fill on a sheet with a variety of sheet effects, including beveling and a transparency effect. Unfortunately, the lighter frozen water fill has a bit of a transparency acne problem.

But that problem seems to disappear with the darker water, which also has a stronger contrast with the floor, so I'll just go with that.

Here's the above-ground areas of the Frostmaidens' Cradle, lair of the alpine hags. The underground areas will make use of the Ice Caverns annual.

I also drew in shadows beneath the elevated huts so that I could create battlemaps with the houses hidden, for combat underneath the houses. (They're supposed to be about 10 feet off the ground.) I was going to use tree stumps as the poles supporting the houses, but the Marine Dungeons columns were right there and I do love them -- and there are versions that conveniently already have the ripple effect added for the huts that overhang the water..

First pass of the outdoor areas of the Forest Hags' lair, the Withering Glade. The premise is that elves once used it as a shrine, but the hags drove them out, poisoning the Great Tree in the center of the glade.

I've been experimenting with using the Forest Trails cliff symbols back to back to make ridges. One other thing I tried, inspired by something I saw Ricko do: instead of using the grass and dirt fills with the grass and dirt patches symbols to make the edges more raggedy, I only used the dirt and grass patches. There are also two sets of all of the tree sheets (including tree parts for stumps and tree shadows), so that some could be beneath cliffs and others above. I thought I would need multiple sheets for the cliffs to show ascending elevation, but I didn't. Had to keep reminding myself that it's all an optical illusion. Amazing how things you can trick the eye, especially when, like the cliffs in Forest Trails, you draw in the shadows instead of relying on sheet effects.

Zooming in, here's one of the three caves used by the coven of hags as bedrooms.

Here's a zoom in on the henge (which operates as a teleportation circle). The gray tree at the cliff base in an Animated Tree. It was a dryad's tree, but the dryad was turned into one of the hags, corrupting her tree. You might notice some vines growing out of the cliff wall near the tree. They are animated, grasping at the hags' captives and serving as organic shackles. This is the only one above ground but there are more within the caves.

Oh, and in the southeast corner, a trio of harpies have set up a nest.
