The Prison

An ancient underground fortress carved into a remote island mountain, holding beings older than the courts themselves in darkness and silence.

Also known as: The Mountain Prison, The Black Keep, The Silent Mountain, The Island of the Damned

What They Know

The Prison was built in the age before the courts, by powers whose names are now forgotten, to hold things that could not be killed.
The iron door at the summit is sealed by a spell that requires the blood of a High Lord to open — and even then, only from the outside.
The cells are not locked by keys but by wards woven into the stone itself; each cell is a separate pocket of silence, so that no prisoner can speak to another.
The oldest prisoners are not fae at all — they are remnants of older worlds, beings of shadow and hunger that the Cauldron itself could not unmake.
The Bone Carver is one of the Prison's most famous inmates, though he is not truly imprisoned — he chose his cell and can leave whenever he wishes, but has not done so for millennia.
The Weaver, who spins the threads of fate in her cottage, is said to be a former prisoner who escaped — or was released — and the Prison remembers her departure with a kind of hunger.
