The Orrery of the Silent Heavens

The chamber is a massive obsidian dome where the floor is polished black marble reflecting a starless sky. In the center stands a towering brass machine of concentric rings and delicate crystalline spheres that hum with a low, bone-rattling vibration. The air is heavy with the scent of ozone and the dry dust of ancient parchment, while a single pool of blue light from the ceiling illuminates a central slot and three iron hand-wheels. Every few seconds, the gears click with a heavy, metallic thud that echoes through the silence of the room.
