The Moonlit Archives — An AI-Built Diagon Alley Roleplay (Vampire · Auror · Broker)

Final Product: The Moonlit Archives

The Moonlit Archives is a playable AI roleplay — a live, slow-burn gothic romance in a candle-lit bookshop in Diagon Alley, running in your browser with nothing to install.

The shop has been closed for a decade, and you have owned it for eight days, and tonight all three of its most dangerous former customers have found their way back in. Lucian Ashford, a 312-year-old vampire antiquarian, tells you your magic tastes like your great-aunt's and that he has been waiting for you. Alaric Thorne, an Auror spending magic he cannot afford, stumbles in with a bleeding shoulder and asks you not to ask questions. Cassian Vane, the black-market broker who always shows up when you are in trouble, leaves a note under a book: They are coming for the grimoire tonight. Trust no one — including me.

From that first line the story is yours. Answer in your own words, or tap one of the suggested moves, and a live AI agent writes the next beat, keeps all three men in character, and quietly tracks how far each of them trusts you. Three investigable threads run underneath — the grimoire that enforces the Accord of 1872, the truth behind Alaric's failing magic, and what Cassian has really been sent to do — each with its own clues, discoveries and consequences.

Game Features

  • Live LLM Narrative Direction — nothing here is a fixed script. A deepseek-flash agent reads your action, keeps Lucian, Alaric and Cassian in voice and writes the next beat, the subtext and the suggested moves as you play. The same agent planned the premise, the prologue, the relationship graph and the three investigable threads from a single world prompt.
  • A Cast That Stays In Character — three men, three registers. Lucian answers with courteous, oblique menace and speaks in centuries; Alaric is blunt, exhausted and ruinously dutiful, spending his own life force on shield charms; Cassian is charming, evasive and always three steps ahead. No assistant tone, no drift.
  • Answer In Your Own Words — Or Tap A Move — type any action into the free-text box, or pick one of the suggested moves: ask Lucian what his reason is before you let him near the restricted section, force Alaric to sit while you take the ward-castings off him, or follow Cassian out into the alley. Every choice lands differently, and each man remembers what you chose.
  • Three Investigable Threads — The Grimoire and the Accord of 1872 (why three powerful men want a dusty bookshop that has been shut for a decade), Alaric's Failing Magic (why an Auror is casting shields he cannot afford) and Cassian's Real Mission (why a broker always knows when you are in danger). Each thread carries its own clues, actions, discoveries and consequences that decide which ending you can reach.
  • Save, Load, Restart — And Adventure Settings — a session menu keeps the whole night exactly where you left it: save the run, load an earlier turn, restart the story, or open Adventure Settings to tune how the AI narrates. Promises, secrets and grudges persist, so the story resumes the moment you return.
  • Painted Scenes, Transparent Sprites, Zero Install — five painted bookshop backdrops and three cinematic CGs were generated in the world's own art direction, and eight character sprites were cut out with birefnet-general into true transparent PNGs, so each man stands cleanly over any candle-lit scene. The whole story is a mobile-first page — free to start, nothing to download.

Character Sprites

Production Process Breakdown

Stage 1: World Buildingdeepseek-flash
The world "Handsome Men in the Galaxy" set the house art direction — refined semi-realistic painterly, value-defined contours, organised shadow planes, warm translucent midtones, small controlled speculars, idol semi-3D painterly. For this story the AI narrowed it into a Cheliz-style otome digital painting: watercolour-ink softness, painterly loose edges, soft cinematic lighting, subtle paper grain and a muted antique palette of charcoal, parchment gold, candlelight amber and deep burgundy.
Stage 2: Roleplay & Story Draftingdeepseek-flash
From a one-line premise the agent wrote the playable spine: the opening night in the closed bookshop, the relationship graph between you and the three men, three investigable threads (the grimoire and the Accord of 1872, Alaric's burnout, Cassian's real mission) with their clues and consequences, four locations (The Moonlit Archives, the Restricted Section, the Leaky Cauldron back room, the Ministry Auror Division), and the default opening line — "Your magic tastes like your great-aunt's. I've been waiting for you."
Stage 3: Scene & CG Artgpt-image-2
Six scene assets were painted with GPT Image 2 in 16:9 — the bookshop interior at late afternoon, the private study above it at midnight, the same shop at first dawn, the rooftop at dusk and the hidden vault behind the shop — plus three 3:2 cinematic CGs at the counter, in the study and at the curtained window before sunrise.
Stage 4: Character Art & Expression Passesgpt-image-2
Lucian Ashford was generated first as a full-body sprite against a pure white matte, then four expression passes (warm, playful, tense, quiet) were generated against that same reference so every pass keeps the same man, pose, outfit and composition. Alaric Thorne and Cassian Vane were rendered as full-body character illustrations in their own scenes — the ruined Ministry corridor and the shadowed wizarding alley.
Stage 5: Transparent Cut-Outbirefnet-general
Every white-background sprite and character illustration was background-removed with BiRefNet into a true transparent PNG — no matte edges, no white box — so Lucian, Alaric and Cassian composite cleanly over any painted bookshop scene.
Stage 6: Visual QA & One-Click Publishneta-studio
The build was checked in-browser — scene framing, sprite scale, text contrast in dark and light, and the live turn flow — then published in one click to a shareable play link, with the world's backdrops, sprites and prompts left reusable by any fork.

Scene Backgrounds

Asset Prompts

Bookshop Interior — Late Afternoon Background Promptneta-studio
"Interior of a 300-year-old antiquarian bookshop in a wizarding alley at late afternoon — towering dark wooden shelves to the ceiling crammed with ancient leather-bound books, dust motes drifting in a shaft of golden window light, a worn Persian rug, a heavy oak counter, a brass bell over the door, faint smell of old paper and candle smoke, cozy and vast and a little haunted. Cheliz-style otome digital painting, watercolor-ink softness, painterly loose edges, subtle paper grain, soft cinematic lighting, muted antique palette of charcoal, aged parchment gold, candlelight amber and deep burgundy, value-defined, restrained elegance. 16:9 widescreen background illustration for a visual novel, no text, no watermark, no people, no UI, dialogue area in lower third kept calm and uncluttered."
Private Study at Midnight Background Promptneta-studio
"A private study above the bookshop at midnight — gaslight lamps, walls lined with first editions, a coal fire dying low, two velvet armchairs facing each other across a small table, a grandfather clock, tall curtained windows with a sliver of moonlight, intimate, hushed, charged with the feeling of a conversation that should not happen this late."
Bookshop at First Dawn Background Promptneta-studio
"The bookshop at first dawn — pale rose and gold morning light through the front windows, the same towering shelves now soft and ordinary, a kettle steaming on a small stove behind the counter, a single chair pulled close to the cold fireplace with a book left open on the seat, quiet, tender, the world beginning again."
Rooftop at Dusk Background Promptneta-studio
"The rooftop above the bookshop at dusk — weathered slate tiles, chimneys and gables of a crooked magical alley stretching below, the first stars appearing in a violet-to-amber sky, a small wrought-iron table with two teacups, warm lamplight spilling from a skylight behind, melancholic and beautiful, the moment before night fully falls."
Hidden Vault Background Promptneta-studio
"The hidden vault behind the bookshop — a round stone chamber lit by a single candelabra, shelves of sealed iron-bound grimoires behind a locked wrought-iron gate, a central reading lectern with one open book, dust suspended in candlelight, ancient and slightly dangerous, the air thick with old magic."
Lucian Ashford Character-Sprite Promptneta-studio
"Full-body character sprite of Lucian Ashford, a 312-year-old vampire antiquarian bookseller — tall and lean, standing centered, head to toe fully visible, feet on the ground line. Pale porcelain skin, dark hair silvered at the temples swept back loosely, calm grey eyes with ancient weariness, high cheekbones, a small old paper-cut scar on one finger. Dressed in an antique black Victorian tailcoat over a charcoal waistcoat, loose white shirt, undone dark cravat, dark trousers, polished old boots. Neutral composed expression, hands relaxed at his sides, posture of a man who has learned to stand very still. Pure white matte background (#ffffff), no shadow on floor, no scene, no props, no text. Cheliz-style otome digital painting, watercolor-ink softness, porcelain skin with subtle warm undertone, painterly loose edges, refined detail, soft cinematic lighting, subtle grain."
Expression-Pass Prompts (Warm · Playful · Tense · Quiet)neta-studio
Each pass keeps the reference sheet and changes only the face: "WARM expression: a soft, rare, genuine smile reaching his eyes, gentle warmth, the composure loosening." · "PLAYFUL expression: dry-witted amusement, one eyebrow slightly raised, the ghost of a teasing smile, eyes bright." · "TENSE expression: jaw tight, guarded, eyes darkened with held-back wanting, the stillness of a man restraining himself." · "QUIET expression: soft, vulnerable, looking down-then-up, ancient loneliness showing at the edges, gentle and open." Every prompt ends: "Full-body character sprite, head to toe fully visible, feet on the ground line, standing centered, pure white matte background (#ffffff), no shadow, no props, no text."
Alaric Thorne & Cassian Vane Character Promptsneta-studio
"Alaric Thorne, a 31-year-old Auror with exhausted determined expression, dark hair, wearing Ministry Auror robes with protective charms glowing faintly, holding his wand, full body portrait showing signs of magical burnout, dramatic moody lighting." · "Cassian Vane, a half-blood expelled Slytherin with sharp cunning features, dark messy hair, wearing black market broker attire mixing wizarding and muggle street fashion, dangerous charming smile, full body portrait in shadowy Knockturn Alley atmosphere." Both were then background-removed with BiRefNet into transparent sprites.
Visual-Novel CG Prompts (Grimoire · Wrist · First Kiss)neta-studio
"Over-the-counter close moment in the candlelit antiquarian bookshop: a young woman's hand and a pale vampire bookseller's hand closing together over a black leather grimoire, fingers just brushing, his grey eyes lifting to her face with dawning, careful hunger and wonder, dust motes in golden light, towering dark shelves behind." · "Hushed midnight moment in a gaslit study above a bookshop: the pale vampire bookseller lifts a young woman's wrist to his lips with both hands, eyes closed, not biting — breathing her in, tasting her magic, three centuries of restraint on the verge of breaking; she watches him, unafraid; low firelight, velvet armchairs, a stopped grandfather clock." · "At a tall curtained window above the bookshop at the blue hour before sunrise: the young woman and the pale vampire in a first kiss, his hand gentle at her cheek, her fingers in his hair, the sky behind them breaking into rose and gold over crooked chimneys, tender and restrained, centuries of loneliness ending." Each ends: "Cheliz-style otome digital painting, watercolor-ink softness, painterly loose edges, soft cinematic lighting, subtle grain, muted antique palette of charcoal, parchment gold and deep burgundy. 3:2 cinematic full-bleed visual-novel CG, no text, no watermark, no UI."
Transparent Cut-Out Stepbirefnet-general
Every white-background sprite and expression pass is run through BiRefNet background removal, producing a true transparent PNG — no matte edges, no white box, ready to composite over any painted backdrop. Eight character sprites were cut out this way for The Moonlit Archives, from 450×1632 expression sheets to the 1254×1254 in-game portrait.
16:9 Cover Key-Art Promptgpt-image-2
"16:9 video game cover key art for the AI roleplay 'The Moonlit Archives'. Scene: the candle-lit interior of a 300-year-old antiquarian bookshop in a wizarding alley at midnight, towering dark wooden shelves crammed with ancient leather-bound grimoires, dust in the lamplight, moonlight through a tall arched window. In the foreground right, Lucian Ashford, a 312-year-old vampire antiquarian — tall and lean, pale porcelain skin, dark hair silvered at the temples swept back, calm grey eyes, antique black tailcoat over a charcoal waistcoat and loose white shirt with an undone cravat — holds an antique leather book and lifts his eyes toward the viewer. Behind him, half in shadow: Alaric Thorne, a 31-year-old Auror in a dark Ministry greatcoat, exhausted and determined, a faint protective charm glowing at the tip of his wand; and Cassian Vane, a charming black-market broker in a black leather coat, leaning against a shelf with a dangerous half-smile. Three men, one archive, romantic tension and quiet menace. Mood: moonlit, intimate, slow-burn, dangerous. Style: refined semi-realistic painterly, value-defined contours, organised shadow planes, warm translucent midtones, small controlled speculars, idol semi-3D painterly, soft cinematic lighting, subtle grain. Composition: cinematic key-art poster, figures on the right third, generous open space on the left for a title, 16:9 landscape. No text, no watermark, no UI."
