Its story
What it looks like
At low water, a ring of black river stones rises around a drowned altar.
Pale blue script moves beneath the current like fish. At night, the water reflects a procession of hooded figures who are not present on the bank.
Why it is here
To preserve the cult's chosen inhabitants from death by hiding them in an ageless, deathlike sleep until the river's patron calls them to wake.
Who made it
The drowned priests of the Choir Beneath, who bargained with a river power to preserve their chosen people from a prophesied war.
Lore
The Choir Beneath believed a prophecy foretold the extinction of their river people.
Its priests wrote the names of every inhabitant into a ledger, then drowned themselves around the altar to seal their bargain. The river obeys the ledger literally, treating descendants and adopted members differently according to the cult's original naming rite. Some villages have survived for generations by keeping their names out of the water's memory.
