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 Heartstone Pendant burned against
Rory's chest. Not metaphorically.
The crimson gem was hot
enough to scorch through her jumper, and the silver chain felt like a brand against her collarbone.
She pressed a palm against
it, trying to gauge if second-degree burns were in her immediate future. "It's reacting."
Nyx's voice drifted from somewhere
behind her left shoulder. Or maybe her right.
The Shade had a disconcerting
habit of existing in multiple places at once. "Brilliant observation."
The standing stones of Richmond
Park
loomed
ahead, ancient oaks twisted into impossible shapes.
Rory had walked past them
a dozen times on delivery routes. They'd always been trees. Just trees.
Now they pulsed with faint
silver light. "Time moves differently inside," Isolde said.
She'd appeared beside them without
footsteps
, because of course she had.
The Half-Fae's silver hair caught
the moonlight like spun glass. "An hour within might be moments without. Or days." "Comforting."
Rory touched the Fae-Forged Blade
at her hip.
The moonsilver dagger had seemed
like overkill when Isolde first pressed it into her hands three weeks ago.
Now she wished she'd brought
a proper sword. Or a flamethrower.
The pendant pulsed again, synchronizing
with her heartbeat. "The Grove accepts you," Isolde said. "Walk between the third and fifth stones. Don't touch them." "What happens if I touch them?" "Best not to find out."
Rory exchanged a glance with
Nyx, who had coalesced into something approximating human form.
Their violet eyes glowed faintly
in the darkness, and their features shifted like smoke whenever she
tried to
focus on them. "I'll go first."
Nyx stepped between the stones
before Rory could argue. The air rippled. For a moment, Nyx's form stretched thin as parchment, elongated across impossible dimensions.
Then they were through, standing
in a space that shouldn't exist behind a circle of trees in Richmond bloody Park. "Your turn," Isolde said.
Rory took a breath and
walked forward.
The Veil felt like pushing
through cobwebs made of electricity. Her skin prickled. Her teeth ached. The pendant flared hot enough that she gasped, stumbling through into cool grass that felt wrong under her trainers. Too soft. Too alive. "Bloody hell." The Fae Grove spread before her in defiance of physics and geography. Wildflowers bloomed in colours that didn't exist in nature, petals shifting between shades her brain couldn't
quite process
. The sky above was twilight, locked in that
perfect
moment between day and night, scattered with stars that formed constellations she'd never seen. The air tasted of honeysuckle and something sharper, like the ozone smell before a thunderstorm. "Beautiful, isn't it?" Isolde materialized beside her, leaving no footprints in the impossible grass. "And dangerous." "You could've led with the dangerous part." "Where's the fun in that?" Nyx drifted ahead, their form less substantial here.
They looked more like living
shadow than humanoid, stretching and contracting as they moved between patches of darkness cast by trees that grew in spirals. Rory followed, one hand on the dagger's hilt. The Heartstone had cooled to merely uncomfortable now that she was inside, but it still
pulsed
with
warmth
. Leading her somewhere. The path through the Grove wasn't marked, but she
could feel
it. A subtle pull in her chest, separate from the pendant's
warmth
. Like following a compass made of instinct rather than metal. "Don't eat anything," Isolde called from behind. "Don't accept gifts. Don't make promises." "Standard Fae rules, got it." "And don't—" A branch snapped to Rory's left.
She spun, dagger drawn before
conscious thought caught up with reflex. The blade gleamed with inner light, illuminating a grove of trees whose bark
looked like mother-of-pearl
. Something moved between them. Too quick to see properly. Too many limbs. "What was that?" "Residents." Isolde's voice held warning rather than fear. "The Grove exists between realms. Things gather here. Most are harmless if unprovoked." "And the ones that aren't harmless?" "Run
very
,
very
fast." Perfect. They moved deeper. The flowers grew denser here, creating carpets of shifting colour that hurt to look at directly. Rory caught glimpses of creatures in her peripheral vision, things that vanished when she turned her head. A fox with too many tails. A bird whose wings left trails of silver fire. Something small and chittering that might have been a squirrel if squirrels had
crystalline
fur and compound eyes. The trees changed as they walked. The spiraling oaks gave way to willows whose branches hung with what
looked like glass ornaments
. Except the ornaments moved, swaying without wind, and Rory could swear she saw images inside them. Moments frozen in
crystal
. A woman's smile. A child's first steps. Someone's last breath. "Memories," Nyx whispered. Their voice sounded clearer here, less like wind through graves. "The Fae collect them. Trade them." "That's deeply unsettling." "Most Fae things are." The pendant pulled stronger now, dragging her toward a clearing ahead. Light spilled between the trees,
not sunlight or moonlight but something else entirely
. Something that made her bones ache with recognition she couldn't name. Rory pushed through the last curtain of willow branches and stopped dead. The clearing was circular, ringed by stones that actually
were standing
stones, not twisted trees.
They glowed with runes that
shifted and changed as she watched, cycling through alphabets she didn't recognize. In the centre of the circle sat a well. Not a wishing well or a water well. This was older. The stones around its rim were worn smooth by countless hands, and the darkness inside it
seemed to
have depth beyond what the
structure
's size should allow. Like looking into space between stars. "The Sight-Well," Isolde said.
She'd gone still in a
way that made Rory's instincts scream danger. "I didn't think it would show itself to you. Not this
quickly
." "What does it do?" "Shows truth. Past, present, future. Depends on what you ask. Depends on what it thinks you need to see." Rory approached the well
slowly
. The pendant had gone from warm to burning again, insistent against her sternum.
Her reflection wavered in the
darkness below, but it wasn't quite right. The face looking back had her features, but the eyes were different. Harder. Haunted by things she hadn't lived yet. Or maybe things she had lived and forgotten. "Don't look too long," Nyx said. They'd gone solid beside her, violet eyes fixed on the well's
depths
. "Some truths are meant to stay buried." But Rory was already leaning forward, drawn by the pendant's pull and something else. A need she couldn't articulate.
To understand what she'd stumbled
into. Why a delivery driver from Cardiff
was standing
in a Fae Grove with a magical dagger and a pendant that burned like prophecy. The water below, if it was water,
began to
glow. Images formed in the darkness. A door covered in frost. A throne made of bones. Her own face, older, scarred, standing before something vast and terrible that her mind refused to process. And then, cutting through everything else, a single symbol burning bright crimson. The same symbol
etched
into the Heartstone against her chest. Rory jerked back, heart hammering. The well's surface went still, returning to impenetrable darkness. "What did you see?" Isolde's pale lavender eyes held
something between concern and calculation
. "I don't—" The Grove shuddered. It was subtle at first. A ripple in the air, like heat haze over summer tarmac.
Then the flowers began to
close, petals curling inward. The
crystalline
creatures scattered.
Even the memory-ornaments swung violently
on their willow branches. "Someone's opened another entrance," Isolde said. Her voice had gone flat. Dangerous. "Someone who shouldn't be able to." "Can they get to us?" "The Grove has many paths. Many clearings. But if they know where to look..."
She turned to Rory, and
for the first time, the Seer looked genuinely worried. "How much do you trust that pendant?" "I don't even know who gave it to me." "Then we have a problem." The shuddering intensified. One of the standing stones cracked, rune-light bleeding from the fissure like luminescent blood. The well's darkness rippled, and Rory could swear she heard something massive moving in its impossible
depths
. "Time to leave," Nyx said.
They'd gone incorporeal again, form
shifting between solid shadow and empty air. "Now." "Which way?" Rory's hand found the dagger's hilt again. The moonsilver blade hummed under her fingers, responding to whatever
was happening
around them. Isolde pointed toward a gap between trees that Rory was certain hadn't been there moments ago. "There. Quickly." They ran. Behind them, something
began to
emerge from the well.
