Not the easiest thing to take a quick picture of, but I quickly painted up some Copplestone Castings terrain I had tucked away – here they are posed on my small 30×30 board. They’ll do a good job of acting as either spawn points or points of interest (maybe to find the entrance to the cave system).
They look a bit shiny here, it’s just the light though. I have actually left the black stones glossy though (no highlights, flat black, shiny). Gives them a nice Cthullu touch.
