Human: Produce a detailed written description of a mystical setting with a library and a carpet. Assistant: 
Open windows let in faint moon and starlight along with an occasional cool night breeze. The sparsely furnished room only has a few comfortable chairs and a big heavy desk. A mithril chandelier that glows brightly without any sign of flame provides more than enough light along with the large fireplace. One large plush carpet covers the flagstone floor from wall to wall.
