The Star-Catcher Orrery

The domed ceiling is painted with a deep indigo night sky, swirling with glittery dust that catches the flickering light of three brass orbs suspended by jointed arms. A heavy pedestal stands in the center of the room, featuring three interlocking rotating rings inscribed with celestial glyphs. Each ring governs one of the spheres above. The scent of ozone and cold metal hangs in the air, while a soft, mechanical hum vibrates through the stone floor whenever the rings are touched.
