Human: Produce a detailed written description of a lonesome scene inside of a medieval keep with tarred oak, an orb, and a column. Assistant: 
The floor, the ceiling and the walls are all constructed of the same ash planking. Placed every few feet is a thick support column of tarred oak. Pale, thin light is provided by a softly glowing orb hanging from the ceiling in the center of the entryway. Dust covers everything. The air is stale and absolutely still.
