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 under
Rory's palm, a low vibration
that
crawled up her arm and settled behind her teeth. "That's new,"
she muttered, snatching her hand
back. "You touched it."
Nyx's voice slid out of
the shadow pooled at the base of the nearest oak.
They flowed upward, taking solid
shape, all sharp shoulders and glowing violet eyes. "I would not have touched it." "You could've mentioned
that
before." "I am mentioning it now." Between two of the ancient trunks, the air
shimmered
like heat over tarmac, though no
warmth
came off it.
Just a faint distortion, a
wrongness, as if the world behind the stones had
been painted
by someone working from a half-remembered dream. Rory squinted. Beyond the shimmer she saw colour
that
had no business existing. Grass too blue. Flowers too bright. She stepped through. The cold hit first.
Not the damp London chill she'd left behind in Richmond Park, but something cleaner, sharper, like biting into a winter apple
.
The sound of the city
vanished. No traffic, no aeroplanes overhead, no distant dog barking. Silence so complete it pressed against her ears.
Then the silence broke, and
she understood it had never been
silence
at all. Bells. Thousands of them, tiny and
crystalline
, ringing from every direction. She turned, hunting the source, and found it in the flowers.
Each bloom carried a bead
of dew at its centre, and when the petals
trembled
, the dew chimed. "Oh," she breathed. "Wonder is dangerous here."
Nyx materialised beside her, their
form less stable now, edges fraying like smoke caught in a draught. "It dulls the parts of you
that
keep you alive." "You're cheerful today." "I am cautious. There is a difference."
The grove stretched ahead, far
larger than the modest clearing it had seemed from outside.
The oaks here grew impossibly
tall, their crowns lost in a sky the colour of old bruises, purple shading to gold at the edges. Light fell in slanting columns, though Rory could find no sun.
It simply existed, the way
light existed in a memory.
She walked deeper, boots sinking
into moss
that
gave like a mattress.
Isolde had warned her about
this place. *
Time moves crooked in the deep grove
*, the Seer had said, peeling a pear
that
never
seemed to
grow smaller. *An hour might cost you a heartbeat. Or a year.*
Rory pressed two fingers to
the pendant at her throat.
The Heartstone lay cool and
quiet. No portal
near
, then. Small mercy. "There." Nyx pointed. A path wound between the trees, paved with flat white stones
that
glowed faintly underfoot. Each stone bore a carving, worn nearly smooth. Rory crouched over one. A face stared back, half-human, half-something with too many eyes. "Don't read them aloud," Nyx said. "They're not words." "They were, once. Names. The Courts paved their roads with the names of the forgotten."
Their voice dropped
. "Walk on them and you carry a little of
that
forgetting with you. Best move
quickly
." She stood, skin prickling. "You've been here before." "I have been *
near
* here. The grove between is not a place one visits twice the same way."
They drifted ahead, scouting, their
shadow-form thinning to a ribbon
that
slipped between trunks and snapped back. "It rearranges. Like a book
that
shuffles its own pages." The path opened into a hollow ringed with stones taller than any cathedral spire. At its centre stood a pool,
perfectly
round, its surface flat and black as polished obsidian. No reflection. The columns of light bent around it, refusing to touch the water. Rory stopped at the edge.
Her own face should have
stared up at her.
Instead she saw nothing, just
depth, a
darkness that seemed to breathe
. "Don't lean over it," Nyx said. "I'm not." "You are."
She caught herself, toes curling
away from the rim. She hadn't noticed leaning. The pool wanted her closer.
She felt the pull, gentle
as a hand at the small of her back. A sound rolled across the hollow. Not the bells now. A long, low note, like a horn blown in a cave, and the moss beneath her feet
trembled
in answer. "What was
that
?" Nyx had gone still, which for a being of shadow meant they had simply stopped existing in any particular shape.
Their voice came from everywhere
and nowhere. "Something
that
lives in the deep grove. Something
that
does not like visitors who linger
near
the seeing-pool." "We're not lingering. We're leaving."
She turned, and her heart
dropped. The path
was gone
. Where the white stones had wound between the oaks, only unbroken moss remained, and the trees themselves had shifted, crowding closer, their bark slick and dark. "Nyx." "I see it." "The path was right there." "The grove rearranges. I did warn you." A pause. The horn-note sounded again, nearer. "We should not have stopped to admire the flowers." Rory drew the Fae blade from inside her jacket. Moonsilver caught the strange light and threw it back, the leaf-shaped edge glowing soft and cold. The
weight
of it steadied her. Isolde had given it freely, and Isolde gave nothing without reason. "Will this cut whatever's coming?" "It cuts most things." Nyx coalesced beside her, solid again, violet eyes fixed on the wall of trees. "Whether it cuts *
that
* fast enough is another matter." The flowers had stopped ringing. Every dew-bead hung silent, and in
that
silence
Rory heard breathing
that
was not her own and not Nyx's. Slow. Vast. Wet. Something moved between the oaks. Not a shape so much as an absence, a place where the strange light bent and drowned, exactly like the pool.
It came forward, and the
moss died beneath it, blackening in a spreading ring. "Behind me." Nyx's hand closed on her shoulder, cold as the blade in her fist. "When I move, you run. Towards the stones. The tall ones." "You said the path
was gone
." "The path is gone."
Their edges sharpened, hardening into
something almost knightly, almost armoured. "We make a new one." The thing in the trees opened an eye. It was the pool.
It had always been the
pool, and the pool had always been watching, and Rory understood with a cold
lurch
that
they had walked into the centre of the
very
thing they should have fled. The horn-note became a scream. Nyx shoved her hard, and Rory ran.
