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 parted like
ribs.
Rory stepped through first, Nyx
a
whisper
of shadow at her shoulder. Behind them, the sounds of Richmond Park cut off mid-note.
A crow's caw turned to
silence
.
Wind died between one breath
and the next. The Grove breathed instead. Not air. Something thicker. Sweeter.
Rory's lungs filled with it
and her chest tightened, just for a moment, before her body remembered how to process whatever this place offered instead of oxygen.
Wildflowers bloomed at her feet
in colours she had no names for. Violet-gold. Blue-green shot through with silver.
They pulsed faintly, in rhythm
with her heartbeat. "Bloody hell."
Nyx flowed forward, their form
solidifying enough to run incorporeal fingers through the grass. The blades didn't bend.
Instead, they shimmered where Nyx
touched them, like water disturbed by a stone. "Language suggests discomfort."
Isolde's voice came from everywhere
and nowhere. "Yet your
pulse
indicates fascination."
The Seer stepped from behind
an oak that hadn't been there a moment ago. Or perhaps it had.
The tree's bark shifted between
grey and silver depending on how Rory looked at it. Reality felt negotiable here. "How long have we been inside?"
Rory checked her watch
. The second hand twitched backwards, forward, backwards again, like it couldn't decide. "How long would you like to have been inside?" "That's not how time works." "Isn't it?"
Isolde's silver hair caught light
that came from no visible sun. Above them, the sky shifted through shades of twilight, never quite settling on dawn or dusk. "You've brought questions. The Grove likes questions."
The Heartstone pendant warmed against
Rory's chest.
Not the urgent heat it produced near Hel portals, but something gentler
. Almost welcoming.
She touched it through her
shirt. "Is it responding to this place?" "Everything responds to this place."
Isolde moved deeper into the
Grove, her feet making no sound on the moss-covered ground. True to the stories, she left no footprints. "The question is whether you're listening to what it says." Nyx had drifted ahead, drawn to a cluster of mushrooms growing in a
perfect
spiral. They glowed with soft phosphorescence. Blue, then green, then back to blue. "Don't touch those." The Shade jerked back. "Poisonous?" "Recursive. Touch one and you'll experience the same moment over and over until you learn what the moment wants to teach you. Most people take decades." Isolde stepped over the spiral without looking. "A demon-hunter from Bristol is still trapped in his third loop. Been forty years." "He's here?" Rory
scanned
the clearing. "Time moves differently, remember? For him, it's only been an afternoon. He's learning about patience." Isolde's lavender eyes fixed on Rory. "You came seeking answers about the blade." It wasn't a question. Rory still answered. "You gave me a weapon I don't know how to use." "Did I?" "You handed it to me last month. Said it would serve me well. That's giving." "I placed it in your hand. You chose to close your fingers around it." Isolde stopped beside a pool of water that reflected stars despite the twilight sky. "The blade knows its purpose. Whether you align with that purpose is your concern, not mine." Rory's jaw tightened.
She'd forgotten how much she
hated Fae double-speak. Every conversation with Isolde
felt like trying to grab smoke
. Nyx materialized beside the pool, their violet eyes fixed on the reflection. The water showed London's skyline, but wrong. Buildings twisted at impossible angles. The Thames ran uphill. Big Ben's clock face displayed thirteen hours. "Is that real?" "Define real." Isolde knelt by the pool's edge. "The water shows possibilities. Futures that might be. Pasts that never were but could have been. London as it exists in the spaces between choices." The Heartstone
pulsed
again. Rory pulled it free from her shirt, letting it dangle on its silver chain. The deep crimson gem caught the strange light and threw it back in
fractured
patterns. "The pendant was made in Dymas." Not a question. A statement. "Prince Belphegor's realm." "Was it?" "You know it was. Stop playing games." "Games have rules. I'm teaching you to see without them." Isolde reached up and plucked something from the air. A thread of light, thin as spider
silk
.
She wound it around her
finger. "Gluttony isn't just hunger for food. It's hunger for knowledge. Experience. Power. Someone in Dymas crafted that pendant as a key." "To what?" "To what indeed." The thread dissolved. "You carry a Fae blade and a demon artifact. An interesting collection for someone who claims no allegiance to either realm." The Grove darkened. Not gradually. All at once, like a switch had flipped. The wildflowers' glow intensified, throwing long shadows that moved independently of their sources. Nyx's form scattered, then reformed, agitated. "What's happening?" "The Grove is showing you." Isolde's voice remained calm. "Look." Between two trees that definitely hadn't
been positioned
there before, the air tore. Not dramatically. Not with sound or fury.
It simply opened, like a
wound in reality. Through it, Rory glimpsed amber sky and sprawling vineyards. The scent of roasted meat and honey wine flooded the clearing. Dymas. The pendant grew hot enough to hurt. Rory grabbed it, the chain biting into her palm. "It's a compass," Nyx whispered. "A lodestone." "Clever Shade." Isolde stood. "The pendant doesn't warm near Hel portals. It warms when it wants to guide you home. To Dymas. It's been calling you since the moment it touched your skin." The rift
pulsed
once, twice. Rory watched shapes move through the amber haze. Human-shaped. Or close enough. One turned towards the tear in space and for a moment, she swore it saw her. Recognised her. Then the rift sealed. The Grove brightened back to its twilight
standard
. Rory's hands shook.
She shoved the pendant back
under her shirt. "Someone in Dymas wants me there." "Someone in Dymas made sure you'd find your way." Isolde began walking again, deeper into the Grove. "Whether that's an invitation or a summons is semantics." "There's a massive difference between an invitation and a summons." "Not to demons."
They walked in silence for
what might have been minutes or hours. Rory's phone was as useless as her
watch
. No signal. No time.
Just the eternal twilight and
the
pulse
of growing things that shouldn't exist. The trees grew denser. Older.
Their roots wove together above
the ground in patterns that looked almost intentional. Rory caught glimpses of things moving between the trunks. Quick flashes of movement. Nothing she could focus on. "Is anything actually dangerous here?" "Everything is dangerous here." Isolde stopped at the base of an enormous oak.
Its trunk was easily ten
metres across. Symbols had
been carved
into the bark, then grown over, then carved again. Layers of markings centuries deep. "Danger and safety are human constructs. The Grove simply is." "That's not helpful." "Truth rarely is." Isolde pressed her palm against a particular symbol. The oak shuddered. Its roots uncoiled like fingers, revealing a hollow beneath. Inside, something glinted.
