Generate for me a description of a foreboding scene inside a castle with gypsum and a carved floor.

This large, round chamber is dimly lit by four sets of torches that have been spaced in cardinal locations around the room. Oddly, while the flames of the torches do flicker, they do not burn down. Whether this is due to some strange and unknown temporal magic or the power of something far greater than mortal ken is hard to ascertain. Gypsum and minerals glitter from within their prisons in the smooth stone, and the floor is carved with a complex circular knotwork pattern.
