The Drowned Litany of Mercy and Chains

The chamber lies beneath a flooded plaza in the sunken city, a circular sanctum of coral-scarred marble where pale sea-light filters through cracks overhead and drifts over a black basin rimmed in brass. Five shell-stelae stand around the water like broken choir stalls, their glyphs glowing faintly whenever the tide shifts. Above the basin hangs a bronze halo clasped to a cold iron chain, and within the depths two shapes, one radiant and one horned, sleep in uneasy suspension. Every few breaths the chamber exhales a low hymn, and the seal answers with a shiver that sends silver bubbles and ash-like motes upward, warning that something below is beginning to stir.
