Human: Compose a short description of a spooky scene inside a medieval hallway with a door, black rug, and snowflakes. Assistant: 
The natural stone ceiling overhead slopes down into a narrow corridor. Nestled into the wall is an iron-bound door surrounded by slender veins of black and white minerals running up the surface of the stone. A cylindrical skylight is carved vertically into the stone, offering limited amounts of lighting. Stretching from wall to wall is a plush black rug peppered with embroidered snowflakes.
