Starry cavern

This top-down scene depicts a subterranean ruin, a winding, dark grey cavern path cutting through crumbling ancient stone structures and leading into deep black voids. Prominent among the debris-strewn flagstone rooms is a central chamber emanating a powerful, vibrant emerald-green glow from an arcane circular pool on its floor, illuminating scattered tools and a large circular metal mechanism. Elsewhere, debris-choked chambers contain broken wooden crates, skeletons, and a tattered crimson tapestry, all under a dim, oppressive light interspersed with faint blue bioluminescent sparkles along the raw rock walls, creating an atmosphere of forgotten magic and decay.
