The Glasswick Reliquary

A single-room chapel of fused white sand-glass, blown rather than built, its walls rippling like frozen water and chiming faintly when the wind hits certain panes. It sits atop a black basalt outcrop overlooking a tidal flat, reachable only at low tide via a causeway of sun-bleached whalebone posts. No moss, no cracks, no weathering — the glass repels grime as though newly formed each dawn. A bronze bell hangs outside under a fin-shaped awning, its rope woven from kelp fiber that never rots.

Inside, the light refracts into shifting rainbows across a floor of packed white sand raked into concentric spirals. A single altar of pale coral holds seven fist-sized orbs of captured sea-light, each pulsing on its own slow rhythm like a heartbeat. The air smells of brine and warm glass, and sound behaves strangely here — voices carry crystal-clear, but footsteps vanish entirely. Small tide pools recessed into the floor hold trapped starfish that never seem to die.

• The seven orbs are not decorative — each one contains the trapped soul-light of a drowned sea-priestess, and removing one causes the tide to rise unnaturally within the hour until it is returned
• Beneath the sand floor is a sealed hatch leading to an air-filled grotto where the shrine's true founder, a still-living but ageless sea-hag turned penitent, has slept in glass-encased stasis for three centuries
• The bell's kelp rope, if burned, releases a fine mist that lets anyone nearby breathe underwater for one hour — Ilsera does not know this, but the cormorant reacts violently whenever someone approaches the bell with a torch
