The Censer of Surrender

You enter a circular chamber of white marble that should feel clean, yet the air tastes faintly of metal and old smoke. Above you hangs a tarnished silver censer, suspended ten feet overhead by a black chain that disappears into the domed ceiling. Pale incense leaks from its sealed seams in slow, deliberate pulses. Three floor plates surround a bronze control pillar, while a wall inscription depicts kneeling figures covering their mouths, releasing a cord, and opening their eyes. Every few breaths, the chain gives a soft metallic shudder, as if the room is waiting for someone to begin.
