Human: Produce a detailed written description of a warm scene inside a mansion with gaethzen hemispheres, limestone, floor, and walls. Assistant: 
The room, a monochromatic tribute to the shade of grey, smells of rich leather, fine linen, and dry paper. Roughened limestone tiles cover the floor and continue halfway up the walls where they connect with the slightly lighter painted walls. The ceiling boasts four gaethzen hemispheres, one in each corner, that provide a warm, even light.
