// THE PREMISE
What this world is
Grimhollow is a blighted march at the edge of a dying kingdom, where the old roads run through haunted forests and drowned moors, and the things that live in the dark are not superstition. Two centuries ago a desperate king's forbidden ritual tore the world open, and now the drowned dead walk the fens, wraiths haunt the plague-emptied villages, and a Cult of the Drowned King feeds something ancient stirring beneath the Weald.
The lords who once kept hunters on retainer are dead or fled, and the Church's monster-hunters, the militant Order of the Ashen Lantern, are too few and too zealous, purging old folk-traditions as often as real horrors. So the frightened folk of Grimhollow pin contracts to the boards of roadside inns and pay hard coin to anyone with the skill and the stomach to make the roads safe. You are one of those hunters, and you start with a worn blade, a few tricks, an empty purse, and a name nobody knows.
This is a world of contracts, and each one is a mystery before it is a fight. A miller's daughter taken by something in the millpond. A manor whose new lord is not what he seems. You track the thing, learn what it is and what it fears, gather the silver or fire or old rite that will kill it, and decide what the truth is worth once you find it, because the monster is not always the one with claws. Coin is the payment, but reputation is the real currency, and the march remembers every contract you take, every lord you cross, and every monster you spare or slay.
// PLAY PROFILE
What this world plays like
Your first ten turns are one contract and the lessons it teaches. You read the board at the crossroads, you talk to the terrified refugees, you learn what silver costs and what the Ashen Lantern thinks of freelancers. The march is already learning your name.
By turn fifty you have a reputation, a few contacts among the alchemists and cunning-folk, and standing with the Ashen Lantern, House Vane, and the fen-heretics that is real and often at odds. The lord who hired you on turn twelve tried to cheat you, and you remember, and so does he. Some of the monsters you let live remember too.
By turn one hundred you are the hunter folk send for when nothing else has worked, courted by lords and feared in the dark, and the choices you made, the coin over the right thing, the beast spared or slain, have shaped the march as much as any sword. The Cult beneath the Weald has noticed you. It has been patient.
Grimhollow does not reset between sessions. Close the tab. The dark keeps its own ledger.
// FACTIONS IN MOTION
Principal factions
The militant church of the Sanctified Flame, dedicated to purifying Grimhollow with fire and faith. Its Lanternates hunt monsters, heretics, and practitioners of forbidden lore, enforcing a brutal doctrine that blames mortal weakness for the Withering. They act as a parallel authority to the Petty Lords, often wielding more influence over the common folk through fear and hope.
The ruling family of Gravewater Crossing, one of the few remaining noble lines clinging to power. Lord Emeric Vane struggles to maintain his authority through tolls on the King's Road and the swords of his house guard. They represent the decaying feudal order, their stone keep a symbol of a security that no longer truly exists.
A ruthless smuggling syndicate that controls the black market along the Salt-Stained Shore. They defy the authority of both Lords and the Church, trafficking in scarce goods like steel, salt, and alchemical reagents. Their operations thrive in the shadows, using hidden coves and bribed watchmen to move their illicit cargo.
A loose confederation of isolated Marcher-Folk and Fen-Born communities deep within the Weald of Sighs. Condemned as heretics by the Ashen Lantern, they practice the old ways of appeasement, leaving offerings to the land and its ancient inhabitants to ward off the worst of the blight. Their survival depends on secrecy and a deep, instinctual understanding of their blighted homeland.
A clandestine society of alchemists and natural philosophers obsessed with distilling the essence of the world's corruption. They believe a definitive cure or power can be found within the blighted flora and monstrous fauna seeping from the Wet Below. Their pursuit of knowledge is amoral, viewing the horrors of Grimhollow as mere reagents for their forbidden experiments.

// SITES OF RECORD
Places that matter
A stretch of rolling plains and grasslands, dotted with small, walled farming villages and crumbling watchtowers. This is the heartland of Grimhollow, where most people live and where the roads, though dangerous, are at least still visible.
A vast, ancient forest of gnarled, moss-choked trees, its interior riddled with stagnant swamps and foggy fens. The air is thick and still, and the canopy so dense that it is perpetually twilight beneath. The Weald is known for its silence, broken only by the buzzing of corpse-flies and the groans of the drowned dead.
A bleak stretch of coastline characterized by towering, eroded cliffs, black-sand beaches, and treacherous tides. The air is heavy with salt and the screams of gulls. Wreckage from unlucky ships litters the shore, picked clean by locals and things that crawl out of the sea on foggy nights.
A transitional zone where the familiar forests of the north give way to a hotter, more aggressive form of jungle. The trees are larger, the shadows deeper, and the sounds of unseen creatures are constant. This is the edge of the known world, a place where old ruins are being swallowed by vegetation and ancient evils stir.
A stretch of coastline where the land is slowly surrendering to the sea and the encroaching jungle. Waterlogged ruins of old towns stand half-submerged in brackish marshes, their stone buildings covered in vines and barnacles. A perpetual, sickly-smelling mist hangs over the area.
// LIVE TURN
A real turn from this world
The innkeeper will not meet your eyes as she slides the coin across the table. "It took the Harrow boy three nights back. Second child this month." She finally looks up. "The Lantern says pray. The lord says it's wolves. You've got a hunter's look, so I'll say what they won't: it comes from the millpond, and it wears a face we knew."
Outside, the fog has come up early off the fen.
Reputation in the Tallowlands: a first contract, on a knife's edge. Grimhollow remembers the hunters who came back, and the ones who did not.
// SYSTEM RATIONALE
Why Grimhollow holds up over a long campaign
Most AI roleplay tools are built around a single session. They start to fall apart at hour ten and are barely playable at hour fifty. Grimhollow doesn't, because the world isn't living in a chat history - it's living in a database.
Mechanical truth in a real database. Coins, inventory, NPCs, factions, locations, properties - all in real database rows. The narrator describes around the database; the database is what's true. By turn 500, your business ledger still balances and your apprentices still have the names you gave them.
Long memory that doesn't fade. The hundredth turn still knows what happened in chapter two. Old threads stay intact instead of blurring into vague backstory.
The right detail, when it matters. A promise you made 800 turns ago resurfaces at exactly the moment it counts. The world kept the receipt.
