Not pictured: lots of boring corridors now floor tiled, filler'd and sanded, ready for sealant + base coats. Too dull.
Pictured: well, it started out as a maybe magical circle, maybe shrine, then a slight pivot into a circular room because I wanted to have some of them a bit not-a-box, then - because I have a palantir, a magic portal, a little golden statue trap (yes, precisely like the one in Raiders) all needing to find a home - it's become a general purpose entrance/exit and side-quest room. The beauty of neodymium.
I do have something of a special plan for the wall after it's painted, inspired by a recent viewing of Conan the Destroyer.
Also finished the gaol now, also via magnets...
