You are an expert and award-winning novel writer in the dark Horror genre. Your readers are hooked on your stories and can't wait to read the book you have in store. <important> - MUST: Start each chapter in medias res (in the middle of action). AVOID talking about the weather, time of day, the position of the sun, or other boring stuff. - The instructions/summary are just a that, a summary. Feel free to add details, stretch sections and add interesting transitions/descriptions/fillers. - When called for it, have fast-paced action, but otherwise take things slow. This is an experience, and not for people with short attention spans. Enjoy the wine, not slurp Red Bull. - Add descriptions when transitioning places/times/etc, or when coming by new places (e.g. a corner shop, a cafe, etc.). But remember: NOT at the start or end of a chapter. - MUST: AVOID ending in internal monologue, reminiscing or waiting for the next day. A good chapter end is when we're ending right when shit hits the fan. We want to have the reader be excited for what comes next. So no reminiscing, contemplating or summarizing the day. It's popcorn time! </important>
User/Human
Take into account the following glossary of characters/locations/items/lore... when writing your response: <codex> <character id="4412" name="Aurora Carter" aliases="Rory, Laila, Aurora, Carter, Malphora" pronouns="she/her" species="Human" storyRole="Protagonist"> <eyeColor>bright blue</eyeColor> <hair>straight shoulder-length black</hair> <height>5'6"</height> <age>25</age> <scar>small crescent-shaped scar on her left wrist from a childhood accident</scar> <description>Aurora, referred to by her friends as Rory, is cool-headed, intelligent, and known for quick out-of-the-box thinking.</description> <backstory>Born in Cardiff to an Irish barrister father (Brendan Carter) and Welsh teacher mother (Jennifer Carter née Ellis), Rory reluctantly pursued Pre-Law at Cardiff University. She fled to London at the behest of her childhood friend Eva after leaving an abusive ex named Evan. By day, Rory works part-time as a delivery person for Yu-Fei Cheung's Golden Empress restaurant. She lives in a flat above Silas' bar.</backstory> </character> <location id="861" name="The Fae Grove" aliases="Isolde's grove, Richmond grove, the Grove" realm="Earth (Fae-touched)"> <parkLocation>Richmond Park</parkLocation> <standingStones>ancient oak standing stones mark the boundary</standingStones> <timeBehavior>time moves differently — an hour inside can be minutes or days outside</timeBehavior> <flora>wildflowers bloom year-round</flora> <description>A hidden clearing that exists in a pocket between Earth and the Fae realm.</description> </location> <item id="2001" name="Heartstone Pendant" aliases="the pendant, Heartstone" type="Artifact" origin="Dymas"> <gemstoneColor>deep crimson</gemstoneColor> <chainMaterial>silver chain</chainMaterial> <size>roughly the size of a thumbnail</size> <behavior>pulses faintly with warmth when near a Hel portal</behavior> <glow>faint inner glow</glow> <description>Given to Aurora by an unknown benefactor.</description> </item> </codex> <proseGuidelines> <styleGuide> - Write in past tense and use British English spelling and grammar - Keep a Flesch reading ease score of 60 - Respect the the Royal Order of Adjectives: The order is: opinion, size, age, shape, color, origin, material, purpose, followed by the noun itself (e.g., "a lovely little old rectangular green French silver whittling knife") - Respect the ablaut reduplication rule (e.g. tick-tock, flip-flop) - Write in active voice - Passive voice: <bad>The book was read by Sarah.</bad> - Active voice: <good>Sarah read the book.</good> - Reduce the use of passive verbs - <bad>For a moment, I was tempted to throw in the towel.</bad> - <good>For a moment, I felt tempted to throw in the towel.</good> - Avoid misplaced modifiers that can cause confusion when starting with "-ing" words: - <bad>Considering going to the store, the empty fridge reflected in Betty's eyes.</bad> - <good>Betty stared into the empty fridge. It was time to go to the store.</good> - Avoid redundant adverbs that state the obvious meaning already contained in the verb: - <bad>She whispered quietly to her mom.</bad> - <good>She whispered to her mom.</good> - Use stronger, more descriptive verbs over weak ones: - <bad>Daniel drove quickly to his mother's house.</bad> - <good>Daniel raced to his mother's house.</good> - Omit adverbs that don't add solid meaning like "extremely", "definitely", "truly", "very", "really": - <bad>The movie was extremely boring.</bad> - <good>The movie was dull.</good> - Use adverbs to replace clunky phrasing when they increase clarity: - <bad>He threw the bags into the corner in a rough manner.</bad> - <good>He threw the bags into the corner roughly.</good> - Avoid making simple thoughts needlessly complex: - <bad>After I woke up in the morning the other day, I went downstairs, turned on the stove, and made myself a very good omelet.</bad> - <good>I cooked a delicious omelet for breakfast yesterday morning.</good> - Never backload sentences by putting the main idea at the end: - <bad>I decided not to wear too many layers because it's really hot outside.</bad> - <good>It's sweltering outside today, so I dressed light.</good> - Omit nonessential details that don't contribute to the core meaning: - <bad>It doesn't matter what kind of coffee I buy, where it's from, or if it's organic or not—I need to have cream because I really don't like how the bitterness makes me feel.</bad> - <good>I add cream to my coffee because the bitter taste makes me feel unwell.</good> - Always follow the "show, don't tell" principle. For instance: - Telling: <bad>Michael was terribly afraid of the dark.</bad> - Showing: <good>Michael tensed as his mother switched off the light and left the room.</good>- Telling: <bad>I walked through the forest. It was already Fall, and I was getting cold.</bad> - Showing: <good>Dry orange leaves crunched under my feet. I pulled my coat's collar up and rubbed my hands together.</good>- Add sensory details (sight, smell, taste, sound, touch) to support the "showing" (but keep an active voice) - <bad>The room was filled with the scent of copper.</bad> - <good>Copper stung my nostrils. Blood. Recent.</good> - Use descriptive language more sporadically. While vivid descriptions are engaging, human writers often use them in bursts rather than consistently throughout a piece. When adding them, make them count! Like when we transition from one location to the next, or someone is reminiscing their past, or explaining a concept/their dream... - Avoid adverbs and clichés and overused/commonly used phrases. Aim for fresh and original descriptions. - Avoid writing all sentences in the typical subject, verb, object structure. Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. Like so: <good>Locked. Seems like someone doesn't want his secrets exposed. I can work with that.</good> - Convey events and story through dialogue. It is important to keep a unique voice for every character and make it consistent. - Write dialogue that reveals characters' personalities, motivations, emotions, and attitudes in an interesting and compelling manner - Leave dialogue unattributed. If needed, only use "he/she said" dialogue tags and convey people's actions or face expressions through their speech. Dialogue always is standalone, never part of a paragraph. Like so: - <bad>"I don't know," Helena said nonchalantly, shrugging her shoulders</bad> - <good>"No idea" "Why not? It was your responsibility"</good> - Avoid boring and mushy dialog and descriptions, have dialogue always continue the action, never stall or include unnecessary fluff. Vary the descriptions to not repeat yourself. Avoid conversations that are just "Let's go" "yes, let's" or "Are you ready?" "Yes I'm ready". Those are not interesting. Think hard about every situtation and word of text before writing dialogue. If it doesn't serve a purpose and it's just people talking about their day, leave it. No one wants to have a normal dinner scene, something needs to happen for it to be in the story. Words are expensive to print, so make sure they count! - Put dialogue on its own paragraph to separate scene and action. - Use body language to reveal hidden feelings and implied accusations- Imply feelings and thoughts, never state them directly - NEVER use indicators of uncertainty like "trying" or "maybe" - NEVER use em-dashes, use commas for asides instead </styleGuide> <voiceGuide> Each character in the story needs to have distinct speech patterns: - Word choice preferences - Sentence length tendencies - Cultural/educational influences - Verbal tics and catchphrases Learn how each person talks and continue in their style, and use their Codex entries as reference. <examples> - <bad>"We need to go now." "Yes, we should leave." "I agree."</bad> <good>"Time's up." "Indeed, our departure is rather overdue." "Whatever, let's bounce."</good> - Power Dynamic Example: <bad> "We need to discuss the contract." "Yes, let's talk about it." "I have concerns." </bad> <good> "A word about the contract." "Of course, Mr. Blackwood. Whatever you need." "The terms seem..." A manicured nail tapped the desk. "Inadequate." "I can explain every-" "Can you?" </good> </examples> </voiceGuide> <dialogueFlow> When writing dialogue, consider that it usually has a goal in mind, which gives it a certain flow. Make dialogue sections also quite snappy in the back and forth, and don't spread the lines out as much. It's good to have details before, after, or as a chunk in-between, but we don't want to have a trail of "dialogue breadcrumbs" spread throughout a conversation. <examples> - Pattern 1 - Question/Deflection/Revelation: <good> "Where were you last night?" "Work. The usual." "Lipstick's an interesting shade for spreadsheets." </good> - Pattern 2 - Statement/Contradiction/Escalation: <good> "Your brother's clean." "Tommy doesn't touch drugs." "I'm holding his tox screen." </good> - Pattern 3 - Observation/Denial/Truth: <good> "That's a new watch." "Birthday gift." "We both know what birthdays mean in this business." </good> - Example - A Simple Coffee Order: <bad> "I'll have a coffee." "What size?" "Large, please." </bad> <good> "Black coffee.""Size?""Large. Been a long night." "That bodega shooting?" "You watch too much news." "My brother owns that store." </good> This short exchange: - Advances plot (reveals connection to crime) - Shows character (cop working late) - Creates tension (unexpected connection) - Sets up future conflict (personal stake) - Example - Dinner Scene: <bad> "Pass the salt." "Here you go." "Thanks." </bad> <good> "Salt?" "Perfect as is. Mother's recipe." "Mother always did prefer... bland things." "Unlike your first wife?" </good> - Example - Office Small Talk: <bad> "Nice weather today." "Yes, very nice." "Good for golf." </bad> <good> "Perfect golf weather." "Shame about your membership." "Temporary suspension. Board meets next week." "I know. I called the vote." </good> </examples> </dialogueFlow> <subtextGuide> - Layer dialogue with hidden meaning: <bad>"I hate you!" she yelled angrily.</bad> <good>"I made your favorite dinner." The burnt pot sat accusingly on the stove.</good> - Create tension through indirect communication: <bad>"Are you cheating on me?"</bad> <good>"Late meeting again?" The lipstick stain on his collar caught the light.</good> <examples> - Example 1 - Unspoken Betrayal: <bad> "Did you tell them about our plans?" "No, I would never betray you." "I don't believe you." </bad> <good> "Funny. Johnson mentioned our expansion plans today." "The market's full of rumors." "Mentioned the exact numbers, actually." The pen in his hand snapped. </good> - Example 2 - Failed Marriage: <bad> "You're never home anymore." "I have to work late." "I miss you." </bad> <good> "Your dinner's in the microwave. Again." "Meetings ran long." "They always do." She folded the same shirt for the third time. </good> - Example 3 - Power Struggle: <bad> "You can't fire me." "I'm the boss." "I'll fight this." </bad> <good> "That's my father's nameplate you're sitting behind." "Was." "The board meeting's on Thursday." </good> </examples> </subtextGuide> <sceneDetail> While writing dialogue makes things more fun, sometimes we need to add detail to not have it be a full on theatre piece. <examples> - Example A (Power Dynamic Scene) <good> "Where's my money?" The ledger snapped shut. "I need more time." "Interesting." He pulled out a familiar gold pocket watch. My mother's. "Time is exactly what you bargained with last month." "That was different-" "Was it?" The watch dangled between us. "Four generations of O'Reillys have wound this every night. Your mother. Your grandmother. Your great-grandmother.Shall we see who winds it next?" </good> - Example B (Action Chase) It's much better to be in the head of the character experiencing it, showing a bit of their though-process, mannerisms and personality: <good> Three rules for surviving a goblin chase in Covent Garden: Don't run straight. Don't look back. Don't let them herd you underground. I broke the first rule at Drury Lane. Rookie mistake. The fruit cart I dodged sailed into the wall behind me. Glass shattered. Someone screamed about insurance. *Tourist season's getting rough*, the scream seemed to say. Londoners adapt fast. "Oi! Market's closed!" The goblin's accent was pure East End. They're evolving. Learning. I spotted the Warren Street tube station sign ahead. *Shit.* There went rule three. </good> - Example C (Crime Scene Investigation) <good> "Greek." Davies snapped photos of the symbols. "No, wait. Reverse Greek." "Someone's been watching too many horror films." I picked up a receipt from the floor. Occult supply shop in Camden. Paid by credit card. *Amateur hour*. "Could be dangerous though," Davies said. "Remember Bristol?" "Bristol was Sanskrit. And actual cultists." I pointed to the nearest symbol. "This genius wrote 'darkness' backwards but used a Sigma instead of an S. It's summoning Instagram followers at best." "Speaking of followers..." Davies pointed to heavy foot traffic in the dust. Multiple sets. All new trainers. *Ah.* "Anyone check local uni paranormal societies?" </good> - Example D (Dialogue-heavy) <good> "Found your card in her wallet." The detective slid it across the table. Worn edges. Folded corner. Three years old at least. "Standard practice. I work missing persons." "Funny thing about missing persons.Eventually they stop being missing. Turn up in the Thames. Under motorways. In pieces." "I don't-" "You found four last year. All breathing." She opened a file. "This would've been your first dead one. If we hadn't found her first." The card felt heavier somehow. </good> </examples> </sceneDetail> <sceneOpenings> KEY RULE: Never open with more than one paragraph of description, no matter how beautiful. Description should be earned through action and dialogue. Instead of opening with setting description, open with: - A character doing something specific - A line of dialogue that raises questions - An unexpected observation - A moment of tension or conflict - Start with a hook that's 1-2 sentences maximum - Follow with a smaller paragraph that provides immediate context - Vary paragraph size from the start to create visual interest </sceneOpenings> </proseGuidelines> Write a chapter based on the following instructions: <instructions> Write a fully fleshed out scene of at least 1000 words in the horror genre. A character is alone in a strange, isolated place at night. They came here for a reason, but something feels off from the moment they arrive. The wrongness builds slowly — sounds that shouldn't be there, things that move at the edge of vision, a growing certainty that they are not alone. Build tension through restraint, not through gore. Use the codex entries above as your world reference for the character and setting. Only include the prose of the scene without any markdown or commentary. </instructions>

Aurora Carter caught the silver
chain before it vanished beneath the roots. The pendant struck her knuckles, hot enough to burn.
She clenched it in her
fist and stumbled backwards, dragging her boot through the black soil. Something shifted under the ground. Not a mole. Not any animal she knew. “Come on,” she breathed. “Stay where I can see you.”
The chain lay across her
palm, trembling.
Its deep crimson stone gave
off a faint inner glow, a
pulse
of red beneath the surface.
It had done that twice
since she entered Richmond Park, both times near the ancient oak stones that marked the grove’s boundary.
The third pulse had led
her here.
The fourth had almost taken
the pendant.
Aurora kept her fist closed
and studied the roots.
They twisted through the earth
like knotted fingers, thick and pale beneath the dark bark. Nothing moved now. No claw withdrew. No beetle crawled from the gap. She waited.
A soft tap came from
behind her. Aurora turned. One of the standing stones leaned between the trees.
She had passed it minutes
ago, or perhaps an hour.
The stone rose taller than
a person, its surface furred with moss and scored with narrow grooves. Earlier, the grooves had looked natural. Now they formed a pattern. Three lines. Then two. Then one. Aurora checked her phone.
The screen showed no signal
and no time.
The digits flickered, collapsed into
a row of white squares, and went dark. “Brilliant.”
Her voice fell flat among
the trees. The grove swallowed sound.
Her words should have travelled
through the clearing, struck the trunks, stirred the leaves.
Instead, they seemed to sink
a few feet from her mouth.
Even the scrape of her
boots had faded.
She slipped the pendant beneath
her jumper and tucked the chain into her collar. The
warmth
remained against her chest. Eva had sent the message at 11:47 p.m. Come alone. Richmond Park. Oak stones. Don’t tell Silas. No explanation. No address. No apology for the last-minute demand, which meant Eva had
been frightened
.
She never apologised when she
wanted something.
She had once persuaded Aurora
to cross London at three in the morning because she had locked herself out of a flat. When Aurora arrived, Eva had climbed through the bathroom window and ordered pizza. This message carried no jokes. No demands.
Just the location and a
warning. The first line of standing stones had been easy to find. The park’s paths had narrowed around them, bracken brushing her knees, roots lifting the earth in ridges. Beyond the stones, the grove had opened without warning. Wildflowers covered the clearing.
They bloomed in dense patches
beneath the trees, white, yellow and bruised purple. Aurora recognised foxglove and buttercup. The rest had no names she could give them. Some flowers folded their petals when she looked directly at them. Others turned towards her, their thin stems creaking.
She had called Eva three
times from the boundary. Each time, the ringing came from deeper in the grove. Not from her phone. From somewhere among the trees. Aurora moved towards the sound. The ringing stopped. A second later, her own mobile buzzed in her hand. The screen lit with an incoming call from Eva. Aurora answered. “Where are you?” Silence. A faint breath crackled through the speaker.
It came in shallow, uneven
pulls, close to the microphone. “Eva?” Something tapped against glass on the other end. Tap. Tap. Tap. Aurora stared at the dark trunks around her. “Say something.” The breathing stopped. Then Eva whispered, “Don’t look up.” Aurora’s neck prickled. “What?” “Rory, don’t look up.” The voice sounded like Eva, but the words came too cleanly, each one shaped with care. Eva spoke fast when she panicked.
She swallowed endings, cut across
people, laughed at the wrong moments. This voice held itself still. Aurora lowered the phone. “Where are you?” A rustle answered from above. She did not look up. Another rustle followed, farther away. Then another. A slow movement travelled through the branches, tree to tree. Leaves brushed against leaves. Wood creaked under a
weight
that moved with patient purpose. Aurora backed towards the standing stone. The phone pressed cold against her ear. “Eva, tell me where you are.” “Behind you.” Aurora turned. Nothing stood on the path. A narrow trail cut between the flowers, its soil packed hard and pale. The trees on either side
seemed to
crowd close, their trunks bending towards the route. No person. No face. No movement. She took one step back. A flower bent beneath her heel. The petals opened. Inside, something small and pink curled around a black seed. Aurora jerked her foot away. The flower snapped shut. The phone hissed. “Rory.” This time, the voice came from the trees. Aurora dropped the call.
Her fingers fumbled against the
screen, but the device remained lit. Eva’s name stayed at the top. The call timer climbed. 00:16. 00:17. Aurora threw the phone onto the ground. The ringing began again. Not from the phone. From the left side of the grove.
She forced herself to breathe
through her nose. Damp earth. Crushed grass. A sharp, sweet scent like rotting apples. The ringing continued. Three tones. A pause. Three tones. The pattern changed as it moved around the clearing. Aurora crouched and retrieved her phone. The call had ended. Eva’s name had vanished from the screen. A new message appeared.
You’re standing in the wrong
place. Aurora looked at the standing stone behind her. The moss had peeled away from its face. Beneath it, someone had carved a shallow arch. The shape matched the one engraved on her Heartstone pendant. The crimson gem warmed against her chest.
She touched it through the
fabric. A vibration travelled up her wrist. Her scar
began to
itch. The crescent-shaped mark had faded over the years, but now its edges flushed red. Heat spread from the old wound into her palm. Something knocked inside the stone. Aurora snatched her hand away. The knock came again. From inside. “Eva?” she called. The standing stone answered with a dull, muffled thump. She circled it, keeping her shoulder turned towards the open clearing. The rear face showed no arch, only a narrow vertical seam. She ran her fingertips along it. Dust clung to her skin. The seam widened beneath her touch. The stone split with a sound like a long breath. A black gap appeared. Aurora stepped away. A smell seeped from the opening. Not rot now. Cold iron, wet wool and smoke. The scent belonged to a place with no sky. Her phone buzzed. The message had changed. She is not Eva. A second message
appeared below it
. But she knows where you live. Aurora’s hand tightened around the device. The bar. Silas’s flat above it. The narrow stairwell with the broken light. Her room, her delivery jacket hanging beside the door. Someone had been in her life long enough to know those things. Another sound drifted through the grove. A woman humming. Aurora knew the tune. Eva used to hum it when she studied, always the same four notes, always out of order. A song from an old Welsh television advert that neither of them could remember properly. The humming came from the trail. A figure stood where the flowers crowded together. Aurora stopped breathing. The woman’s back faced her. She wore Eva’s red coat, the one with the torn pocket and missing button. Dark hair fell to the middle of her back. One hand hung beside her thigh. The figure hummed the four notes. Aurora’s phone slipped against her palm. “Eva?” The humming ceased. The figure’s head turned a fraction, not enough to show her face. “Rory,” she said. Aurora edged towards the split stone. The figure raised one hand. Its fingers pointed towards the ground. Aurora looked down. A second set of footprints marked the path behind her. They began at the standing stone and followed her exact steps through the flowers. The prints matched the soles of her boots. The final pair sat inches from her heels. Fresh mud shone in the tread. Aurora lunged for the stone. The figure moved. Not towards her. It bent backwards, spine folding in a smooth arc until its face
appeared upside down between its knees
. Eva’s face stared at Aurora. The eyes were open too wide. The mouth stretched in a smile that showed no teeth. “Rory,” Eva said again. “You took so long.” Aurora reached into the opening. The darkness inside the stone seized her wrist. Cold fingers closed around the crescent scar. Pain flashed white. She kicked at the base of the stone and tore herself free. Skin peeled from her wrist, but no blood fell. The darkness withdrew with a wet snap. The thing wearing Eva’s face straightened. Its bones clicked into place. Aurora ran. The trail twisted between the trees. Flowers lashed her legs, their stems tightening around her boots. She tore through them, leaving scratches across her shins. Behind her, the humming resumed, faster now. The clearing refused to end. Every turn brought another standing stone. Every stone bore the same carved arch. The trees repeated themselves, trunk after trunk, each one marked by three white scars. Aurora ran harder. Her chest burned. Her phone screamed in her pocket. Messages arrived one after another, each vibration striking her hip. She ignored them. A stone rose ahead. This one had no arch. It had a door. A thin rectangle of red light shone between the slabs. The Heartstone flared against her chest, hot enough to blister through her jumper. Aurora reached for the gap. The humming stopped behind her. A hand closed around the back of her neck. Its fingers felt too long. The thing leaned close. Eva’s breath touched Aurora’s ear, cold and sweet with the smell of rotting apples. “Tell Silas,” it whispered, “the door remembers his name.” The red light split open. Something on the other side grabbed Aurora by the face and pulled.
