You are an expert and award-winning novel writer in the dark Fantasy 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>

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 fantasy genre. A small group enters an ancient, otherworldly place for the first time. The environment is alien and wondrous. Describe their exploration — what they see, hear, and feel as they move deeper. Include moments of discovery, unease, and wonder. Let the world-building emerge through the characters' experience rather than exposition. Use the codex entries above as your world reference for characters, setting, and lore. Only include the prose of the scene without any markdown or commentary. </instructions>

The standing stones hummed. Not a sound Rory could hear, exactly. More a vibration that crawled up through the soles of her trainers and settled in her molars, a dentist's drill pitched below human hearing. She pressed her palm against the nearest oak, its bark carved into spirals so old they'd nearly smoothed away, and the hum intensified. Warm. Insistent. Like a heartbeat that wasn't hers. "Don't linger at the threshold," Isolde said from somewhere ahead. "The stones remember the last person who hesitated. He grew roots." Rory pulled her hand back. The grove opened before them like a wound in the world. One moment they stood in Richmond Park, late November, the skeletal reach of bare oaks against a slate sky, and the next they stepped through air that tasted of honey and copper and something older than either. The change hit all at once: temperature, light, sound. London's distant traffic vanished. In its place, a silence so complete Rory heard her own blood moving. Then the silence filled. Birdsong, but wrong. The notes bent in directions that made her inner ear protest, melodies that looped back on themselves and harmonised with echoes that hadn't happened yet. She blinked, and the world resolved into colour. Green. Not the tired grey-green of an English winter, but green so saturated it looked painted, every shade she'd ever seen and a dozen she hadn't. Wildflowers blanketed the forest floor in defiance of the season, their petals shifting hue as she watched, pinks bleeding into golds bleeding into a colour she had no word for, something between violet and the feeling of nostalgia. "Breathe through your mouth," Nyx whispered beside her, their voice its usual wind-carried murmur. "The pollen here can make you forget your own name." "Speaking from experience?" "I don't have a name worth forgetting." They drifted forward, Nyx's shadow-form rippling at the edges where it met the grove's impossible light. The amber glow came from everywhere and nowhere, sourceless, warm as late afternoon sun but without a sun to cast it. Where Nyx moved, the light seemed to bend around them, uncertain, as though it couldn't decide whether they were solid enough to cast a shadow or were themselves a shadow cast by something unseen. Isolde walked ahead, her silver hair catching that sourceless light and fracturing it into tiny rainbows that danced across the moss. She left no footprints. Rory looked down at her own feet and saw she left deep impressions in the moss, each one filling immediately with tiny white flowers that hadn't been there a second before. "Is that normal?" "The grove welcomes you." Isolde glanced back, her pale lavender eyes reflecting light that moved independently of the rest. "Or it marks you for later consumption. I never could tell the difference." "Brilliant." "The Fae word for 'welcome' and 'appetiser' shares the same root." "She's not joking," Nyx said. "I never joke. Half-bloods lack the gene." They pressed deeper. The trees grew taller and stranger the further they walked, their trunks twisted into shapes that suggested intention, doorways and windows and arches that led to more forest, identical and yet subtly wrong, as though each arch opened onto a slightly different version of the same place. Rory's hand drifted to the Heartstone pendant beneath her jumper. It lay cool against her skin. No pulse, no warmth. Whatever this place was, it wasn't Hel. Small comfort, that. A stream cut across their path, its water running in two directions at once, splitting around a stone and flowing both upstream and downstream simultaneously. Rory crouched beside it. Her reflection stared back, but the face was wrong, older, her black hair threaded with grey, her bright blue eyes carrying decades she hadn't lived. "Don't drink it." Isolde's voice carried the particular weight of someone who'd watched others make that mistake. "And stop looking. That's not your future. It's a version of you the grove finds interesting." Rory stood. Her reflection lingered a moment longer than she did, then dissolved. They crossed the stream on stepping stones that rose from the water as they approached and sank behind them once they'd passed. Each stone was warm underfoot, almost body temperature, and Rory tried not to think about what that implied. The trees thinned. A clearing opened. Rory stopped walking. The space before them shouldn't have existed inside Richmond Park, or inside anything. A cathedral of living wood rose around the clearing, the trees having grown or been grown into buttresses and vaults and soaring columns that disappeared into a canopy so far above it might as well have been sky. Bioluminescent fungi, fat and pale as moons, clung to the upper reaches and cast a blue-white glow that mixed with the amber to create something neither warm nor cool. Between the columns, strung with spider silk thick as fishing line, hung dozens of objects Rory couldn't immediately identify. They caught the light and scattered it. She stepped closer to the nearest. A glass sphere the size of her fist, suspended at eye level, and inside it, a tiny storm raged. Lightning the width of a hair struck a landscape of miniature hills. Rain fell upward. "Memories," Isolde said. "Or moments. The grove collects them the way a river collects silt. Over centuries, they accumulate." "Whose memories?" "Anyone who passes through. The stones at the boundary are the sieve. They let you in but keep a piece of you." Rory's hand went to her wrist, to the crescent scar there, a childhood accident she barely remembered. "What piece?" "Nothing you'll miss. A Tuesday you've already forgotten. The smell of a meal you can't recall eating. The face of someone you passed on the street and never thought of again." "And if we stay too long?" Isolde's silence answered that. Nyx had moved to the far edge of the clearing, where the column-trees grew so close together their trunks fused. They pressed one incorporeal hand against the bark and their entire form flickered, shadow stuttering like a candle in a draft. "There's something behind this." Their whisper carried across the clearing with unnatural clarity. "A space. Large." "The heart of the grove." Isolde crossed the clearing in that eerie, footprint-less glide. "I haven't opened it in forty years." "Why not?" "Because the last time I opened it, something inside opened its eyes." Rory reached Nyx's position and felt it, that wrongness that lived in the gap between instinct and reason. The air here tasted different. Thicker. The amber light didn't penetrate the gaps between the fused trunks, and in that darkness, something shimmered. Faint. The barest distortion, like heat haze, but cold. The Heartstone pulsed. Rory's hand flew to her chest. Beneath the jumper, the pendant had gone from cool to warm in the space of a breath, and now it throbbed against her sternum with a rhythm that matched nothing in her body. She pulled it free. The deep crimson gemstone cast a bloody light across her fingers, its inner glow flaring in time with something she couldn't see. "It shouldn't do that here." Isolde's voice had lost its riddling cadence. Flat. Direct. Afraid. "This is Fae ground. That stone answers to Hel." "I'm aware." "Then you're aware that for it to pulse here, something from Hel must be present." The shimmer in the darkness between the trunks intensified. The faint distortion resolved, just for a moment, into a shape Rory recognised from every nightmare she'd had since the pendant arrived. A tear. Jagged at the edges, like a wound in wet cloth, and through it, a glimpse of something that was not this grove, not London, not anywhere that belonged in any world she understood. Warm amber light bled through the tear. Not the grove's amber. Deeper. Richer. The colour of overripe fruit, of honey left too long in the sun, of excess. "The Veil," Nyx breathed. Their form had gone rigid, edges sharp as cut glass. "It's thin here. Paper thin." "No." Isolde stepped back from the fused trunks. "It's torn." Rory stared into the rift. Through that ragged opening, she glimpsed rolling hills carpeted in vineyards that stretched to a horizon that curved the wrong way, as though the land itself bent upward at the edges. Orchards heavy with fruit she'd never seen, colours that made her eyes water, and between them, long tables set for feasts that could seat hundreds. The smell hit her next, roasted meat and caramelised sugar and spices that made her mouth water and her stomach clench with a hunger that felt implanted, alien, not her own. Dymas. She'd never seen it, but she knew. The pendant knew. It burned against her chest like a coal. "Close it," Rory said. "I didn't open it." "Then who, exactly, sent us an invitation?" Something moved on the other side. A shape, distant, crossing between the vineyard rows with a gait that was wrong in ways she couldn't articulate, too many joints bending in too many directions. It paused. Turned. Rory couldn't see its face, not clearly, not through the distortion and the distance and the warm amber haze of a realm that ran on hunger. But she felt it see her. A weight settled behind her eyes, a pressure like fingers pressing against the inside of her skull, and with it came a voice that wasn't sound, a sensation of words forming in the meat of her brain. *Come eat.* The Heartstone flared so bright it shone through her fingers. The rift widened by an inch. Two. Rory drew the Fae blade from her belt. The moonsilver dagger pulsed with its own cold light, and where its glow met the pendant's crimson, the air between them crackled and spat sparks that smelled of burning sage. She held the blade toward the rift and the widening stopped. The tear shuddered at its edges. The shape on the other side took a step closer. "Isolde. Tell me you have a way to seal this." "A song. Old. It will cost me a year of sight." "Nyx?" "I can hold the edges. Keep it from spreading." Their form was already stretching, shadow-limbs elongating toward the rift's ragged borders. "But not for long. Minutes. Less." The shape took another step. Closer now, close enough that Rory could make out arms, too many arms, and a mouth that split the wrong way, vertical, lined with teeth that looked like cutlery. The crescent scar on her wrist itched. "Sing," Rory said. Isolde opened her mouth, and something on the other side of the rift began to run.
