A group of five college friends reunite for Halloween weekend at Harrowgate House, an isolated Victorian manor perched on the cliffs of a small coastal town. What begins as a nostalgic celebration—costumes, cocktails, and horror movie marathons—spirals into a waking nightmare when they discover a hidden room behind a basement bookshelf. Inside: a ritual circle, bone fragments, and a diary belonging to Eleanor Harrowgate, the house's original owner, who was accused of witchcraft in 1892.
As a violent storm cuts off all power and communication, the friends realize they are locked inside. One by one, they begin experiencing vivid hallucinations tied to their deepest guilts and fears. The house itself seems to shift and change. Tempers fray, paranoia takes root, and old wounds resurface. The diary reveals that Eleanor didn't practice witchcraft to harm—she was trying to contain something. Something that has been waiting beneath Harrowgate House for over a century.
The group must determine which threats are real and which are in their minds before the entity fully awakens. As secrets turn lethal and the boundary between friend and enemy blurs, they face an impossible choice: find a way to seal the entity back in the darkness, or sacrifice one of their own to satisfy its hunger.
Style
Slow-burn psychological horror with escalating supernatural dread. The tone is atmospheric and claustrophobic, blending haunted house traditions with the paranoia thriller structure of a locked-room mystery. Horror elements favor suggestion, implication, and creeping unease over gore, though violence punctuates key moments. Character relationships and buried guilt drive the emotional core. The prose should be sensory-rich—emphasizing sound, cold, smell, and the oppressive weight of the house. Unreliable perception is key: the reader should share the characters' uncertainty about what is real.
Setting
Halloween weekend at Harrowgate House, a sprawling, deteriorating Victorian manor on the rain-battered cliffs of Blackwood Cove, Maine. The town is twenty miles down a single winding road, with no cell signal and a landline that crackles with static. The house is a labyrinth of narrow hallways, peeling wallpaper, and drafty rooms filled with sheet-covered antiques. The basement smells of damp earth and something older—copper and ash. Outside, the Atlantic churns gray and violent, and the wind moans through the house's bones like a living thing. Jack-o'-lanterns on the porch grin their last grins as candlelight flickers. The storm intensifies throughout the night, isolating the group completely.
Characters
Maren Cole
28. A archivist grad student who organized the reunion. Maren has always been the group's anchor—calm, practical, the one who holds things together. She rented Harrowgate House for its historical interest, fascinated by its dark past. She carries guilt over drifting from the group after her mother's death two years ago, feeling she abandoned them when they needed her. As the haunting intensifies, Maren becomes obsessed with Eleanor's diary, believing she can understand and outsmart whatever is in the house. Her analytical mind is both her greatest weapon and her blind spot—she struggles to accept that some things cannot be rationalized.
Theo Reyes
28. A high school teacher and Maren's ex-boyfriend. Warm, funny, and self-deprecating, Theo is the emotional glue of the group. He still harbors feelings for Maren but has channeled his energy into being a good friend rather than pressing the issue. Theo has a phobia of darkness rooted in a childhood incident he never fully discusses. As the house preys on fears, he becomes increasingly rattled by shadows and sounds, fighting to maintain composure for the others' sake. His hidden guilt: he knows a secret about the night Maren's mother died that he has never told her.
Jules Fontaine
27. A freelance photographer with an edgy, restless energy. Jules is sharp-tongued and confrontational, often masking vulnerability with sarcasm. She has a complicated history with the group—she briefly dated Theo after he and Maren split, which created lingering tension. Jules is the first to experience the hallucinations and the first to suspect that someone in the group might be working against the others. Her camera becomes a recurring motif: she keeps photographing the house, and some of the images capture things that shouldn't be there. Her guilt centers on a drunk driving incident she covered up with the group's reluctant help.
Dex Whitlock
29. A software developer and the group's skeptic. Dex is rational to a fault—atheist, empiricist, and dismissive of anything supernatural. He treats the weekend as a fun scare, rolling his eyes at the house's history. As events escalate, his skepticism curdles into denial, then into frantic attempts to find logical explanations that no longer hold. His breakdown is the most dramatic because his worldview is the most rigid. Dex carries guilt over a business deal that defrauded a friend outside the group—a secret that eats at him more than he admits. He brought a handgun "for protection," which becomes a source of escalating danger.
Cassidy "Cass" Lowell
28. A nurse and the most empathetic member of the group. Cass is the listener, the caretaker, the one who notices when someone is struggling before they say a word. She has a history of anxiety and takes medication that she ran out of before the trip. Without it, her symptoms resurface: racing thoughts, hypervigilance, and a creeping sense of doom she can't shake. Cass is the first to sense that something in the house is aware of them. Her connection to the supernatural is intuitive rather than intellectual. Her guilt: she was on shift when a patient died under questionable circumstances, and she blames herself.
Eleanor Harrowgate
Deceased. The original owner of Harrowgate House, who lived there from 1865 until her death in 1892. Through her diary, Eleanor emerges as a complex figure—not a malevolent witch, but a woman with genuine occult knowledge who discovered something ancient and hungry beneath the cliffside. She spent decades maintaining wards and rituals to keep it contained, enduring the town's suspicion and eventual accusation of witchcraft. Her diary is fragmented, coded in places, and reveals a mind that was brilliant but fraying under the weight of her lonely guardianship. She is not a villain, but her desperation led to choices that have consequences in the present.
Locations
Harrowgate House
A three-story Victorian manor built in 1865 on the cliffs of Blackwood Cove, Maine. The house is a Gothic architectural fever dream: asymmetrical gables, a turret that leans slightly seaward, and a wraparound porch where paint peels in long strips. Inside, the layout is disorienting—hallways that seem too long, rooms that don't appear on the rental listing, and a basement that extends further than the house's footprint should allow. The décor is preserved but decayed: velvet drapes gone gray with dust, a grandfather clock that ticks without hands, and a fireplace in every room. The house has a presence—a weight, a watchfulness—that grows as the night progresses.
The Hidden Room
A windowless chamber behind a false panel in the basement, accessible through a gap behind a bookshelf. The walls are carved with symbols that Maren can partially translate. A ritual circle is burned into the stone floor, blackened and cracked. Bone fragments—animal, hopefully—are scattered in the corners. Eleanor's diary sits on a stone lectern, remarkably preserved. The room is cold regardless of the season, and the air tastes metallic. The symbols on the walls seem to shift when viewed in peripheral vision.
Blackwood Cove
A small, declining coastal town twenty miles from Harrowgate House. Once a fishing community, it now survives on sparse tourism drawn by the house's notoriety. The town has one store, a bar, and a church. The locals are wary of outsiders and openly hostile to questions about Eleanor Harrowgate. The road to the house is a single-lane track through dense pine forest, prone to washouts in storms. Once the storm hits, the road is impassable.
Objects
Eleanor's Diary
A leather-bound journal, roughly 300 pages, written between 1881 and 1892. Eleanor's handwriting is elegant but deteriorates over time. Entries describe her discovery of the entity, her research into containment rituals, and her growing isolation as the townspeople turn against her. Several pages are torn out. The final entries are frantic and fragmented, referencing a "door that will not stay closed" and a "price that must be paid." Maren uses it as a guide, but its incompleteness makes it unreliable.
The Bone Circle
The ritual circle burned into the floor of the hidden room. It is approximately six feet in diameter, ringed with symbols that correspond to no known tradition Maren can identify. The bone fragments within are arranged in a pattern that suggests deliberate placement. When the group first enters the room, the circle is intact. By the second night, hairline cracks have appeared in the stone, and the circle's edge has widened by millimeters. The entity cannot fully manifest while the circle holds—but the circle is breaking.
Jules's Camera
A vintage 35mm film camera Jules brought for atmospheric shooting. It becomes an unsettling narrative device: photographs developed in the house's darkroom (a converted bathroom) show figures, shapes, and shadows not visible to the naked eye. Some photos depict events that haven't happened yet. The camera's reliability is ambiguous—are the images genuine supernatural evidence, or products of Jules's unraveling mind? The final roll of film may hold the answer to what the entity truly wants.
