Once each year the sea draws back from the Drowned Coast to bare a black temple on the seabed for a single hour. You have come for the pearl said to grant one wish. Read the carvings, the murals and the drowned priest's counsel to learn how the wish — and the tide's terrible price — really work; explore the hall, the bone-field and the vault of drowned gold; and then choose your wish before the sea returns. Watch the tide, gather the lore, and wish well: there are ten ways for this hour to end, and the sea is patient with none of them.
