This is lovely. Which annual are these from? I did a Google search and it suggested Volume 6 (2012), but that might have been something else he did.

Rats! Every sewer has rats (unless gelatinous cubes sweep through them). Those of us with Creepy Crypts can use the rats from that, but you may want to consider adding those symbols for customers who don’t also have that one.

We've been thinking of colors for sewers that are used for their traditional use. But if we start to think of the reasons why a necromancer might need a sewer-type system beneath their lair, or a demon lord, or an archfey, or even dwarves creating subterranean aqueduct, then all sorts of colors make sense: bright water, glowing green goo, rivers of blood, lava...the possibilities are endless.

I posted my comment above prematurely! I was the person on FB who asked if Gelatinous Cubes would be included, so now I'm really sold on this. I'd love to be able to include skeletons, bones, or other metal rubbish in the cubes, but I suspect that could be done by putting the debris on another layer with a semi-transparency effect.

Sue, I love how this shows layers or levels of the sewers descending. I'm really excited for this one. I usually buy the annuals long after the year is over once I decide if I have stuff I want, but I'm already convinced on this one. I will be signing up for the 2024 annual today.
