Opening your eyes slowly, the familiar ceiling comes into view. A canopy with delicate carvings. Soft bedding. Sheets that feel good against the skin.
Everything in this mansion is of the highest quality.
The meals are luxurious, the clothes are well-tailored, and the servants will prepare anything you wish for.
