The Abbey of Four Weather Locks

A circular chamber of pale stone and green-black bronze smells of cold ash and old rain. In the center waits a pedestal crowned with three turning rings, while the walls show a stained mural of moon phases above four floor sockets that faintly breathe mist, ember-sparks, drizzle, or wind when touched. Each wrong adjustment answers with a low chime and a brief pulse of light from the door, while the right one makes the whole room hum like a tuning fork and causes the iron seams to glow silver.
