The Sentence Beneath Blackrush
The Sentence Beneath Blackrush
“A drowned prison keeps its last sentence.”
— Hook · kill
“Three ferrymen have vanished near Blackrush Fen, and a black chain has been found wrapped around the last boat returned. Sergeant Harl Venn offers coin for the deaths to stop, but warns that the old prison bell has begun ringing beneath the water.”
— Hook · kill
The party reaches the edge of Blackrush Fen near dusk. A half-sunken ferry lies against the reeds. Its oars are chained to the deck, the chain is wet with black mud, and a green glow moves beneath the water. From somewhere below the fen comes a single toll of an iron bell.
Sergeant Harl Venn
Sergeant Harl Venn approaches the party at the settlement gate with a sealed purse and a map marked with three vanished ferry crossings. He asks for discretion because the local magistrate refuses to close the marsh road.
Rumours
d4 · table- 01The prison bell rings three times before someone drowns.
- 02The Jailer cannot cross running water, but the fen itself is full of drowned channels.
- 03A ferryman who returned alive refused to speak and later vanished from a locked room.
- 04The magistrate’s grandfather built Blackrush Keep after a war, though no surviving record names the prisoners.
More ferrymen will die, the marsh road will close, and the Mirebound Jailer will begin dragging living prisoners into Blackrush Keep. If the truth remains buried, the haunting may spread to other abandoned prisons built under the same authority.
Background Lore
The old flood-prison of Blackrush Keep lies half-sunk in the fen. It once held debtors, deserters, and oathbreakers beneath the authority of a royal jailer. When the keep was abandoned, the prisoners drowned in their cells. The Jailer remained, bound to its post by an unfulfilled sentence and a chain driven through its own corpse.
A drowned prison beneath Blackrush Fen has become the hunting ground of the Mirebound Jailer, an undead keeper armed with a hooked black chain. The Jailer has killed several ferrymen and now threatens the marsh road. The party must find the prison, kill the Jailer, and survive the drowned cells.
