You are an expert and award-winning novel writer in the dark Literary Fiction 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> <character id="4413" name="Silas Blackwood" aliases="Silas, Si, the Spymaster" pronouns="he/him" species="Human" storyRole="Mentor"> <eyeColor>hazel</eyeColor> <hair>grey-streaked auburn</hair> <height>6'1"</height> <age>58</age> <beard>neatly trimmed, matching his grey-streaked auburn hair</beard> <limp>slight limp in his left leg from an old knee injury</limp> <signetRing>silver signet ring, always worn on his right hand</signetRing> <description>Silas is a retired intelligence operative turned bar owner. He carries himself with quiet authority.</description> <backstory>Former MI6 field agent who retired after a botched operation in Prague left him with a permanent knee injury. He opened "The Raven's Nest" bar in Soho as a front for his network of contacts.</backstory> </character> <location id="854" name="The Raven's Nest" aliases="the Nest, Raven, Silas' bar" realm="Earth"> <signColor>distinctive green neon sign above the entrance</signColor> <secretRoom>hidden back room accessible through a bookshelf, used for clandestine meetings</secretRoom> <description>A dimly lit bar in Soho, London. The walls are covered with old maps and black-and-white photographs.</description> </location> </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 literary fiction genre. Two old friends who haven't seen each other in years run into each other unexpectedly at a bar. One of them has changed significantly. Through their conversation and the tension between who they were and who they've become, reveal the weight of time and unspoken regret. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary. </instructions>

Rory caught the glass before
it struck the floor.
The man who had knocked
it from her hand kept walking, his shoulder already lost in the press at the bar. Gin ran over her fingers. She set the glass upright, then looked up at the woman watching her from the other side of the counter. For a second, Rory saw the girl who used to climb the wall behind her parents’ house in Cardiff, skirts snagging on the broken brick. Then the girl blinked away. “Eva.” “Rory.”
Eva’s voice had kept its
Welsh
lilt
, but something in it had gone flat.
She wore a dark suit
with no crease in the sleeve and a narrow gold watch that caught the green light from the sign outside.
Her hair, once a wild
brown cloud she’d hacked at with kitchen scissors, lay smooth against her jaw. She looked older, of course. They both did. Yet Rory found herself searching for the old Eva in the set of her mouth. “You’re hard to find,” Eva said. “You’ve had six years to practise.” “That’s fair.” It was not an apology.
Rory wiped her wet fingers
on a paper napkin and watched Eva’s eyes take in the small crescent scar on her wrist. “You still have it.” “It’s a scar, not a landmark.” “Your mum took us to A&E. You told the nurse I’d pushed you.” “You had pushed me.” “I was trying to stop you falling.” “You were trying to get the best seat on the wall.” A
flicker
crossed Eva’s face, the beginning of a smile, then she smoothed it away. The bar thudded around them. Glasses clicked.
Somewhere near the back, a
man laughed too loudly at a joke no one else had heard.
The Raven’s Nest had a
way of swallowing people into its shadows. Old maps and black-and-white photographs crowded the walls; the faces in them looked stern enough to disapprove of everyone present. Behind the bar, Silas Blackwood polished a glass with a cloth that had seen better decades.
His hazel eyes paused on
Eva, then moved to Rory. “Friend of yours?” he asked. “Once,” Rory said. Eva glanced at her. “Still am, if you’ll have me.” Rory put the napkin down. “You don’t get to decide that for both of us.” “No. I don’t.”
Silas set a fresh glass
beside Rory’s hand, though she hadn’t ordered one.
His silver signet ring caught
against the rim. “On the house,” he said. “For the spill.” “The spill wasn’t mine.” “Then charge it to the man who walked into you.” “He’s gone.” “Men like that often are.”
He limped away before Rory
could ask what he meant. Eva watched him go. “Your landlord runs a bar with a spy network?” she asked. “He runs a bar.” “Rory.” “Eva.” A quiet sort of challenge passed between them. Eva had always been good at waiting. When they were children, she could sit beside a locked shed for an hour, convinced the cat inside would come out if she stayed still enough. Rory used to get bored and throw stones at the door. “What are you doing here?” Rory asked. “I came to see you.” “You could have called.” “I did.” Rory frowned. “When?” “Two years ago. You changed your number.” “I changed it after Evan found the old one.” Eva’s gaze dropped to the gold watch. Her thumb stroked its clasp. “I didn’t know.” “You didn’t ask.” “I know.” The admission landed between them without ceremony. Rory
hated that it
still had
weight
. Eva ordered a whisky.
She didn’t look at the
menu, and Rory wondered how many things she’d learnt to do without looking. A narrow line showed at the base of her throat where a necklace might once have rested. “You look different,” Rory said. “So do you.” “Is that what people say when they’ve run out of things to say?” “Usually.” Rory’s mouth twitched despite her. Eva noticed. For a moment they were back in Cardiff, stealing chips from a paper cone and arguing over whether a dead bird on the pavement had been a pigeon or a gull.
Then Eva’s drink arrived, and
the moment closed. “You cut your hair,” Rory said. “I did.” “You used to say you’d never cut it short.” “I used to say a lot of things.” “Like what?” “Like I’d never leave you alone with him.” Rory’s fingers stopped against the glass. There. The thing they had both brought into the bar and set
carefully
between them. The thing neither had wanted to touch first. Eva turned the glass by its stem. “I should have come back.” “You should have stayed.” “I know.” “No, you don’t.” Rory kept her voice low. “You sent me a train fare and a list of rooms to rent. You told me London was full of people who wouldn’t know him. Then you stopped answering.” “I thought you’d be safer if I stayed out of it.” “Did he tell you that?” “No.” “Did you tell yourself?” Eva’s hand tightened around the glass. “Yes.” For a while, they listened to the bar. A bottle clinked into a crate. Someone scraped a chair over the floorboards. “I was scared,” Eva said. “So was I.” “I know.” “You keep saying that.” “Because I don’t have anything clever enough to make it better.” “You used to have plenty of clever.” “I spent it all on getting through the day.” That answer surprised Rory.
It sounded less like the
woman in the suit than the girl who used to cut class to sit on the river wall, throwing bits of slate into the water. Rory studied her face. The skin beneath Eva’s eyes had a grey cast. A faint bruise coloured one knuckle, yellow at the edge. “What happened to your hand?” “Door.” “You’ve always been bad at opening them.” “I’ve always been bad at leaving them shut.” Eva placed a small brown envelope on the bar between them. Rory didn’t touch it. “What’s that?” “Something I found.” “You came all this way to give me an envelope?” “I came to tell you what’s inside it.” “Then tell me.” “Evan’s in London.” The room
seemed to
tilt by a degree. Rory’s thumb pressed hard into the side of her glass. “How long?” “I saw him yesterday.” “Where?” “Outside the chambers where I work.” “You work in law now?” “Compliance. It’s duller than it sounds.” “Most things are.” “He was waiting by the entrance. He asked for you.” Rory laughed once. It came out dry. “He knows where I live?” “I don’t know.” “That’s not an answer.” “It’s the only honest one.” Rory pushed the envelope back towards Eva. “You should have called the police.” “I did.” “And?” “They took a statement.” “Good.” “They also asked why I’d waited six years to tell them he threatened you.” Rory looked at her. “He threatened you?” “Not in a way they could use.” “You could have told me.” “I’m telling you now.” “After all this time.” “Yes.” The bluntness of it left no place for Rory to put her anger. She looked at the envelope. A handwritten address showed through the paper, her old Cardiff address, the one she’d shared with her parents. Beneath it, someone had written her name in block capitals. Not Rory. Aurora Carter. “Where did you get this?” “From his car. He left it unlocked.” “You took it?” “I did.” “Why?” “Because it had your name on it.” “That’s not a reason. It’s an excuse.” Eva’s chin lifted. “Fine. I took it because I wanted to know what he was planning.” “And did you?” “No.” “Then you stole a letter and brought it to me.” “I brought it because he said your name.” Rory’s scar prickled beneath the wet cuff of her sleeve.
She lifted the envelope and
found it heavier than paper should be. Something hard shifted inside. Silas had stopped polishing.
He stood at the far
end of the bar, speaking to a customer without taking his eyes from the entrance. Rory noticed the change in him. His shoulders had gone still. “Open it,” Eva said. “You first.” “It’s addressed to you.” “So was the last apology he sent.” Eva looked at the envelope as though it had begun to breathe. “You got a letter from him?” “No. He left it under my door. I didn’t read it.” “Where is it?” “Bin.” “Of course.” Rory tore the envelope along its top edge. A brass key dropped into her palm. A photograph followed, face down. Eva made a small sound. Rory turned it over. The picture showed the entrance to the Raven’s Nest, taken from across the street. The green neon sign burned above the door. Rory stood beneath it in her delivery jacket, one hand on the handle of her bicycle. The image had
been taken
close enough to catch her face. On the back, in the same block capitals, someone had written: You came all this way. Rory’s hand closed around the key. Silas put down the glass he’d been holding. “Both of you,” he said. “Back room. Now.” Eva reached for the photograph. Rory pulled it away. “You knew about him,” Rory said. “I knew he was looking.” “When?” “Not until tonight.” The front door opened. A gust of voices and street noise rushed in, then vanished as a man stepped across the threshold. Evan’s eyes found Rory at once. His smile had not changed. That was the worst of it. “Laila,” he said. Silas moved first, limping fast around the end of the bar. Eva seized Rory’s sleeve. The brass key bit into Rory’s palm as Evan reached inside his coat.
