Human: Make a concise location description of a spooky setting inside a castle with soot, ceiling, flooring, and walls. Assistant: 
The ceiling rapidly ascends into a point overhead, while the walls bow inward, distorting any sense of stability. The walls are covered with blackened soot, a contrast to the otherwise pristine condition of the castle. Ethereal light flickers errantly across the flooring, ceiling, and darkened walls.
