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 pressed her back against
the ancient oak standing stone, the rough bark biting into her jacket.
The grove’s air felt wrong—thicker
than mist, sweet with something sour beneath. She clutched the Heartstone Pendant, its tiny deep crimson gemstone pulsing against her palm, as if it sought escape. Time had warped already.
An hour inside could mean
minutes or days out there.
She tried to focus on
the rhythm of her breathing. A twig snapped.
Nothing moved ahead but the
wildflowers, petals quivering though no breeze stirred. She swallowed.
The silver chain cut into
her fingers as she raised the pendant, the faint inner glow brushing her wrist scar.
Memories of simpler deliveries to
the Golden Empress drifted away, replaced by the Grove’s slow
pulse
. She ought to be here. Eva’s instructions had been clear: meet at the standing stones at midnight. But this felt more like a trap than a rendezvous. She stepped around the stone, dropping into the clearing. Tall oaks formed a ring, their gnarled roots knotting beneath moss.
Petals carpeted the ground in
impossible blooms: violet, gold, frost-white, all opening under the boughs.
She crouched beside a cluster
of pale flowers and slid her fingertips across the soil. Damp, cool, and smelling of old iron.
A scent she recognised too
well.
A low moan drifted from
the tree line. She froze, heart hammering. Not wind. Soft, human.
She crept forward, each footstep
sinking into leaf mold. The moan shaped into words, twisted by
echo
. “Help me…” Her throat went dry. Eva’s voice? But Eva never begged. She
flicked
the pendant.
It pulsed again, hesitating, then
throbbed
like a
pulse
. Talk about bad timing. Aurora closed her hand around the chain and advanced toward the sound. The moan cut off like a snapped thread. Silence pressed in.
She stopped beneath a standing
stone carved with weathered runes. Pale lichen filled the grooves. The runes
seemed to
shift in her peripheral vision, curling into letters she almost recognised. A tremor ran
down her spine
.
Her phone buzzed in her
pocket—no signal, just a warning light flashing.
She sighed and tossed it
aside. Another sound: breath. Close.
She spun, eyes darting between
trunks. Twilight shadows stretched into crouching forms. She dared a step back. The pendant’s
warmth
built,
searing
through leather and bone.
She tore off the chain
and pressed the stone to her lips. “I’m here,” she whispered. Silence answered. A thrum rose beneath her feet, as if the roots themselves
pulsed
. The moon, half-hidden behind a cloud,
flickered
light across the clearing.
She caught movement: a slender
figure slipping between two oaks, half-cloaked in dark.
She lunged forward, hand trembling
around the pendant. “Eva?”
Her voice cracked
. No reply. The figure vanished into a tangle of brambles. Aurora wrenched at thorny branches, ripping them free, but found only broken twigs and damp earth. She cursed, chest tight. This grove played tricks. A rustle behind her. She whipped around. The standing stone
loomed
closer than before. Only metres away. No path led to it. She blinked. Heart pounded. She felt the pendant tug, a magnet pulling her deeper into the ring of oaks. She followed its insistence, weaving through trunks slick with moss. The glow grew stronger, casting a crimson haze across the ferns. A trick of the light? She shook her head and pressed forward. The air grew warmer, almost fragrant, like roses wilting in heat. She counted steps—ten, fifteen, twenty—then came to a fallen cenotaph of stone, half-buried in roots. Moss peeled back as if something wanted to breathe beneath. Aurora crouched and swept moss aside.
Not soil but smooth stone
. An engraving curved across its surface in a script older than any language she recognised. She
traced
the letters, fingertips trembling. The pendant
pulsed
hard, like a heartbeat you could see. She lifted it and brought it close to the engraving. The gemstone flared. Light spilled across the letters, illuminating the curve of each symbol. An image
flickered
in her mind: a door, an abyss beyond, faces pressed against glass, mouths open. She jerked back, gasping. Wind shredded through the grove, though the air had held still. Petals tore from blossoms and whipped around her ankles. A distant laugh, filtering through branches, soft and hollow. Unfamiliar. It wound through the trees, sparking panic. She staggered to her feet, upside-down laughter
echoing
in her skull. The pendant fell from her grip. It rolled across the stone, glowing brighter, then dimmed. She lunged for it, glove snagging on a root. She yanked free, heart
racing
, and snatched the chain. Pain flared where the roots had scraped her hand. She
clenched her fist
around the pendant and ran. Branches whipped at her face. She burst through the ring of oaks and into a stretch of open ground. The moonlight revealed another standing stone, taller than the rest, its peak lost in shadow. It
pulsed
with a dull orange light like embers. On one side, a shallow pool of water mirrored the glow. She skidded to a halt at the pool’s edge. The surface lay still. She bent down and peered in. Face pale, eyes wide. Her reflection
shimmered
, then blurred. Something swam beneath: shapes slithering beneath the surface, scales catching the dull light. She yanked back. The water rippled, sending rings of distortion across the reflection. She pressed a hand to her throat. Dry. A cold tendril of dread curled around her spine. The pendant
vibrated
, a low hum that
pulsed
through her bones. She peered down at it. The glow matched that of the obelisk and the water. Beads of sweat ran down her temple. She
scanned
the treeline. No path back. Every tree looked the same: gnarled, ancient, hungry. The grove had shifted again. Hours ago she had stepped through a fallen oak brace into this pocket.
Now she could not find
her way out. A voice, low as mist, drifted from the obelisk. “You came.” Aurora’s breath caught. She pressed the pendant to her chest and
steeled
herself. “Who’s there?” Silence, then a slow scrape of stone on stone. The obelisk’s glow
pulsed
faster. The ground beneath her
trembled
. She stumbled back, pressing her palm against the cold edge of the pool. The water sloshed, rippling toward her. “No,” she whispered. She raised the pendant high, its glow battling the obelisk’s. The strands of light
flickered
like dying stars. She felt a sway in the earth. Something large moved behind the obelisk, shifting bark and moss like a cloak. A shape peeled into the clearing: tall, slender, with limbs that bent at impossible angles. Skin mottled pale green. Eyes—or holes?—hollow black mirrors. It drifted forward, tilting its head. The glow of the obelisk painted its face in flickering orange. No mouth moved, yet its voice filled the air, low and distant. “Give me the stone.” Aurora’s fingers tightened. “Never.” The figure paused, then reached a crooked hand toward her. Its long fingers curved like brambles. She backed away, the pendant pressed against her heart. The obelisk’s thrum matched her
pulse
. Her vision narrowed until only the creature and the stone remained. Plants
quivered
at the grove’s edge. Petals lifted, swirling in a silent maelstrom. The ground split with a soft creak. Roots buckled. She felt the air choke around her. The creature advanced. Its footfalls made no sound. Aurora steadied herself, gaze locked on the pulsing gemstone. She took a breath and held it. The next moment the creature lunged. She drew back, heart hammering, and the grove erupted. A wave of sound cracked through the clearing as roots snaked up from the earth. Leaves exploded from branches. The obelisk’s glow
shattered
into fiery shards of light. The creature shrieked—no human scream, more like the tearing of bark—and lunged again. Aurora spun, stumbling toward the ring of standing stones. Roots writhed around her ankles. She kicked, yanking free, and
raced
toward the nearest marker. Her palm brushed the cold surface, the runes flaring as the pendant’s glow flared in response. She slammed her hand against the stone, bracing herself. The grove convulsed, twisting the ground beneath her. The creature’s shadow passed over the runes. She pressed harder. The runes glowed, letters sharpening into form. A crack split the air. A
pulse
of light shot from the pentagon of stones, converging on the obelisk. The creature recoiled, shrieking as the beam seared across its chest. Roots buckled under its
weight
. It skidded backward into the darkness. Aurora felt the runes under her palm hum with power. She drew the pendant from her pocket and laid it in the carved hollow at the base of the stone. The gemstone sank into place, clicking against cold rock. The glow spread through the runes like lightning. The creature roared, a sound that shook leaves loose. It skittered forward, silhouette jagged against the blast of light. Aurora braced herself for the final wave. But the light collapsed inward, swirling into the pendant. The obelisk’s glow snapped out. Silence flooded the grove. Aurora staggered back, panting. The pendant lay dark in the stone’s hollow. The creature had vanished. Pebbles cracked beneath her boots. From the treeline came a slow scrape. She
flicked
the pendant’s chain in her hand. It
pulsed
once, faintly, then ceased. A breath escaped her. She dared to look up. At the edge of the clearing stood a figure, tall and cloaked in shadow, face hidden. It stepped forward, boots silent on the moss. “Thank you,”
it said, voice soft as dusk
. Aurora swallowed. The pendant’s glow
began to
swell again, deep crimson light spilling across her fingers. She raised her hand, gripping the chain, as the figure lifted a slender arm to its hooded head. “Now, it begins.”
