Open Throat — An AI-Built Vampire Dark-Romance Roleplay (Three Centuries of Restraint)
Final Product: Open Throat
Cover
The 16:9 key-art cover: Lucian Ashford — a refined aristocratic vampire with black wavy hair, grey-green eyes and pale skin — seated at the centre of a closed, candle-lit antiquarian bookshop after hours, half-lit in warm amber light, one hand at the open collar of a black Victorian shirt, the pulse at his throat bare under the light. Silk bindings and an antique leather book lie on the mahogany desk, and in the tall gilt mirror behind him a shadow moves that is not him. Painted for this story with GPT Image 2 at 16:9 in the world's own idol semi-3D painterly style, image-to-image from the story's in-game scene art so the likeness holds.
Gameplay
Actual gameplay, the opening beat: the bookshop is closed and the lamps are low, and Lucian is kneeling with his wrists bound behind him in silk — bound by you, at his own quiet request — his throat tilted under your thumb. His painted scene art holds the left panel (the 3:4 in-game scene the story itself plays) while the live narration runs on the right, his first line sits under a named dialogue block ("I have not been afraid in three hundred years. Put your hand on my throat and I will show you what that feels like. You decide — that is the whole point. You decide."), and two AI-written moves wait below the free-text action box.
Gameplay
Actual gameplay with the suggested moves set aside: you answer in your own words instead of tapping a prompt. The narration has reached the thing in the mirror and Marguerite's voice at the door — "He offered you his throat? How sweet. My love made the same offer once. Ask him what happened to her." — and the live agent is waiting on whatever you choose to do about it, keeping three centuries of restraint in Lucian's voice.
Gameplay
Actual gameplay, the session menu: Save, Load, Restart and Adventure Settings open over the live scene, so a run can be kept, rewound or reconfigured without leaving the story. Every choice you have made about the mark, Marguerite and the thing circling the shop is preserved with it.
Open Throat is a playable vampire dark-romance roleplay — three hundred years of restraint written and directed live by AI, running in your browser with nothing to install.
Lucian Ashford, 312 years old and the last of the Ashford line, keeps an antiquarian bookshop in Diagon Alley and has never once fed from a living throat. Tonight the shop is closed, the lamps are low, and he has bound his own wrists in silk and tilted his head back so that the pulse at his neck is exactly under your thumb — and handed you the one decision he has never given anyone. You are the first exception in every category. His old enemies have noticed the distraction, the shop's wards have begun to fray, and something in the dark has started circling you both exactly when his perfect restraint is coming apart.
Answer in your own words, or tap one of the suggested moves, and a live AI agent writes the next beat, keeps Lucian in the low, careful register of a man who has said no to himself for three centuries, and moves the romance toward either a mark that binds him to a mortal or a refusal that leaves him unclaimed and unprotected. Underneath it run three investigable threads — Why does Lucian want you to mark him?, Who is Marguerite, really? and What is circling you both? — each with its own clues, actions, discoveries, reveals and consequences.

Game Features
- Live LLM Narrative Direction — nothing here is a fixed script. A deepseek-v4-flash agent reads your action, keeps three centuries of restraint and quiet hunger in Lucian's voice, and writes the next beat, the subtext and the suggested moves as you play. The same agent built the premise, the default opening (the bound wrists, the open throat, Lucian's first line, Marguerite at the door, two quick-start options), the relationship graph, four locations and three investigable threads — his old enemies have noticed, the wards are fraying, and the hunter is using you as bait — from a single one-line prompt.
- Three Centuries of Restraint, One Open Throat — Lucian answers in the register of a man who has said no to himself for three hundred years: low, slow, faintly hoarse, and always more dangerous than he lets himself sound. Marguerite arrives silk-soft and uninvited with an old debt and a warning, and the thing in the mirror stays in the dark as the third presence in every choice. Each stays in character across sessions, and each tracks a different claim on you — hunger, credit, and bait.
- Answer In Your Own Words — Or Tap A Move — type any action into the free-text box ("Put your hand on his throat and make him finish what he started", "Ask Marguerite what happened to the one who made the same offer"), or pick one of the AI's suggested moves. Every reply nudges the mark, the maker's sleep and the hunter closing in.
- Three Investigable Threads — <em>Why does Lucian want you to mark him?</em> follows a claimed-vampire ritual in the shop's old texts, a faint scar in the same place on Marguerite, and a torn journal page reading "protection". <em>Who is Marguerite, really?</em> follows a two-hundred-year debt, the maker asleep in the vault below, and a grief she has been paying for with Lucian's freedom. <em>What is circling you both?</em> follows scratches on the wards, a shadow that does not match its owner, and the reason Lucian checks your windows at night. Each thread carries clues, actions, discoveries and a reveal that reshapes the ending you can reach.
- Four Locations, One Bookshop — the story moves between The Bookshop After Hours, The Basement Vault, The Mirror Hall and Marguerite's Townhouse, and four story directions set where the game of bait and claim can turn: mark him and be hunted together, refuse and leave him unclaimed, wake the maker to buy his freedom, or confront the hunter and end it in open war.
- Painted Sprites, Painted Scenes, Zero Install — Lucian's portraits were cut out with <span class="ml-model-badge">birefnet-general</span> into true transparent PNGs, so he stands cleanly over the lamplit bookshop, the vault, the mirror hall and the townhouse.

Character Sprites
Sprite
The 3:4 scene portrait the game itself plays beside the narration — Lucian in the candle-lit bookshop, black wavy hair, grey-green eyes, a black coat slipping off one shoulder, one hand at his collar and a silver signet ring on his finger. Cut out with BiRefNet into a true transparent PNG — no white box, no matte fringe — so he lifts cleanly off the scene and can be re-staged over any backdrop.
Sprite
The character atom's official cover in the world's archive: Lucian Ashford as a refined vampire bookseller — dark hair swept back, wire-rimmed spectacles, an antique gilt-tooled book held to his chest, a black brooch at his throat and a silver pocket watch on a chain. In this world's own semi-3D painterly house style, background-removed with BiRefNet into a true transparent PNG for clean compositing.

The character reference the story was built from, the anchor for Lucian's likeness — the same refined face and dark hair, spectacles, a monogrammed silver watch chain and a black high-collared coat in warm candlelight, a globe and candelabra dissolving behind him.

Production Process Breakdown
Stage 1: World Buildingdeepseek-v4-flash
The world "Handsome Men in the Galaxy" fixed the house art direction — refined semi-realistic painterly, value-defined contours, organized shadow planes, warm translucent midtones, small controlled speculars, idol semi-3D painterly — and the shared hub of otome romance each work draws from: a court where love is currency and six men each believe she belongs to them. This story grew as one of its gothic routes: a vampire bookseller, three hundred years of restraint, and a hunter using you as bait.

Stage 2: Roleplay & Story Draftingdeepseek-v4-flash
From a one-line premise the agent drafted the playable spine: the default opening (the closed bookshop, the silk binds, the open throat, Lucian's first line, Marguerite at the door, two quick-start options), a relationship graph of intoxicating trust, unravelling restraint, an old debt and a warning, four locations — The Bookshop After Hours, The Basement Vault, The Mirror Hall and Marguerite's Townhouse — plus hooks, four story directions and three investigable threads with clues, actions, discoveries, reveals and consequences.

Scene Backgrounds
BG
The work's own in-game scene art — the 3:4 panel the game actually plays on the left of the screen while the story runs on the right. Lucian in the candle-lit bookshop, lamp low and collar open, the same portrait that doubles as the share card, producing the hushed, intimate atmosphere the live narration is read against.
BG
The Bookshop After Hours: tall dark shelves of antique leather books, a mahogany reading desk under a warm lamp with an open book, a quill and a brass hand bell, silver candlesticks with burning candles, a tall gilt mirror set into the back wall, and rain-streaked mullioned windows onto a dark London street. Where the silk binds are kept and the wards grow thin. Generated with GPT Image 2 at 16:9 in the world's painterly style.
BG
The Basement Vault: a stone chamber beneath the shop, a long carved wooden case like a sarcophagus, iron rings and chains on the wall, a barred grate high on the stone, thick church candles and stacked ledgers on damp flagstones. Where the maker sleeps and Marguerite's debt is stored. Generated with GPT Image 2 at 16:9 in the world's painterly style.
BG
The Mirror Hall: a long shadowed corridor lined with tall gilded antique mirrors, candle sconces along the walls, a faint mismatched shadow moving in the glass, a marble floor reflecting cold blue-grey and warm candle glow, and an arched doorway at the far end. Where the shadows first appeared — and where the hunter watches. Generated with GPT Image 2 at 16:9 in the world's painterly style.
BG
Marguerite's Townhouse: a gothic aristocratic drawing room at night — deep red velvet drapes, a carved marble mantel with a guttering fire, a large framed portrait of a dark-haired woman above it, a velvet chaise, a silver tea service and tarnished gilt on dark wood. Where the old vampire keeps her vigil and her grief. Generated with GPT Image 2 at 16:9 in the world's painterly style.
