The Bellwright's Welcome

You find a circular chamber washed in cold blue witchlight. At its center stands a waist-high stone pedestal holding three tarnished bronze chimes, each carved with a different symbol: an eye, a moth, and a crescent moon. A black-corded handbell hangs beside them. The sealed stone door beyond has an eye-shaped keyhole, and faint blue lines run from the chimes toward it. Dust trembles whenever the handbell moves, as though the room is listening.
