The room lights up, enough to see by. The lantern light flickers. The room is totally circular; it has a diameter of about twenty feet. There are two doors -- the one you came in from, and an identical one directly across from you. The firepit is in the exact center of the room -- there's tinder and firewood beside it, on the opposite side of the cauldron.

The firepit itself is a solid ring of smooth, white stone -- the same material as the floor. The cauldron over the fire is deep and round bottomed, made of cast iron, and it's full of some dark liquid... sea water? Blood? Tar? It's hard to tell. The walls and ceiling are a shiny silver blue nacre, like the inside of a shell. They are lined with narrow wooden shelves all the way around, covered with a miscellany of objects.
