Ancient Desert Ruins

Publisher's blurb: Sandswept ruins crumble under the arid winds, even tucked away as they are within a natural cavern. Stone rubble litters the floors of what might have been an underground crypt, long ago. Pillars hold up stone ceilings with broken patches, while hidden corridors lead to different rooms. A circular chamber lies at its heart, and while square rooms with smaller, circular chambers break off from one another. The place smells like dust and old books.
