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>

Aurora crouched behind a moss-drenched
stone slab, heart hammering beneath the
weight
of her soul.
The pendant at her throat
pulsed
with warm urgency.
She signalled forward with a
crisp nod.
Nyx slid from shadow to
shadow, a faint violet glow pulsing at the corners of their form. They whispered, “The boundary thins here.”
Isolde paused beside a gnarled
oak standing stone, silver hair drifting like mist around her shoulders.
She traced a slender finger
across a rune carved into bark. “Drink deep,” she intoned. “Or starve thirsty.”
Aurora rose and brushed her
palms along rough bark. Copper stung her nostrils. Blood.
The scent threaded through the
grove’s wildflower sweetness.
She tasted unease in the
air.
They passed between two ancient
oaks—shadows stretching like hungry arms—into a clearing lit by drifting motes of pale blue light.
The ground dipped into a
shallow basin that felt hollow underfoot. Rounded stones, each
etched
with runes too worn to read, ringed the hollow like
sentinels
. Nyx hovered at the rim, insubstantial as mist. “A cradle of the Veil,” they whispered. “Tendrils here leech through.”
Their voice trembled, carried on
a breeze that did not belong. Isolde stepped into the basin.
Wildflowers bent towards her with
silent curiosity. She closed her eyes.
A hush fell over the
clearing until even the motes held their breath.
Then she spoke, voice low
as distant thunder. “Where three realms converge, the door yawns open. Gaze with eyes unclouded.”
Aurora’s fingers tightened around the
Fae-Forged Blade at her hip.
Moonsilver shimmered in the
motes’ glow, cold against her palm.
She willed her mind clear
of doubt. One glance, and she would follow Isolde to whatever lay beyond. A tremor
pulsed
through the earth. The runes on the stones glowed pale lavender. Vines curled alive, weaving a lattice above the basin. A shallow gust rattled overhead; motes spun into eddies. “Move,” Aurora whispered.
They descended into the basin
together. The air turned still, heavy with the taste of ozone and distant salt. Aurora shivered,
not from cold, but from a thrill of dread
.
She caught Nyx’s eye; those
violet embers
flickered
.
They stepped to stand beside
her. Isolde reached out, pressing her palm to the ground. Runes under her fingertips sparked like starlight. The vines shuddered, then withdrew. A gap yawned at the centre of the basin, revealing a stone arch carved with knotwork that
pulsed
with shifting colours. Aurora swallowed. The heartstone’s glow intensified, its
warmth
crawling up her throat.
She crouched again, eyes darting
over the arch’s carvings. Twisted faces looked back at her—fae and fiend woven together. Nyx drifted forward, voice a rustle. “The latch lies in the shadow’s heart. We must feed it.” Isolde spoke without hesitation. “Offer fear, or joy, or pain. One must pay the toll.” Aurora glanced at them both.
She did not believe in
coin or sacrifice. Yet the pendant
throbbed
against her collarbone,
as if urging her on
.
She slid the Heartstone from
its chain and placed it on a pedestal carved from the same pale stone as the arch. Light flared. The arch roared with living colour. A widening seam of shimmering distortion tore open the barrier between worlds. Behind it lay a vast hall of
crystal
pillars stretching beyond sight, their facets reflecting impossible skies—liquid opal and molten gold. A hush fell once more.
Even the motes trembled at
the arch’s threshold. Isolde offered a fragile smile. “Welcome.” Aurora slid her blade free.
It whispered as it left
its sheath. She stepped through the arch, mind
racing
. On the other side, the floor
felt like cool glass under her boots
. Aurora knelt and tapped it. A low hum answered.
She rose and peered up
at the nearest pillar. Within its translucent
depths
, silvery shapes drifted—fragments of memory or dream. A face, half-
gleaming
with tears, pressed against the inner surface, mouthing an unheard plea. She flinched back. “What is this place?” Nyx’s voice drifted from beside her. “A vault of longing. Each pillar holds a fragment of someone’s soul.” Isolde
traced
the pillars’ contours with a pale fingertip. “Once, these halls stored the hopes of mortals, gifts to the Fae Courts. Now, they guard a rift that bleeds Hel’s hunger.” Aurora swallowed. “So it’s a trap.” Nyx hovered before a column lit with flickering ruby veins. “The prince of Dymas would devour these souls and feast on despair.” Aurora felt the pendant against her empty palm. The Fae blade in her grip felt heavier, its cold edge pressing reassurance into her fingers. She kept her voice steady. “Then we seal it.” Isolde nodded, eyes distant. “Edge the veil back upon its hinges. But beware: sacrifice any light, and the threshold will swallow it.”
They moved deeper, footsteps echoing
across the glassy floor. Aurora’s reflection rippled beneath her boots. She caught glimpses of herself: dark hair fanned around a pale face, eyes bright with determination. She gripped the blade’s hilt and
steeled
herself. A sudden crack split the air. A pillar
shattered
behind Nyx, spraying fractal shards that scattered like birds startled in flight. Nyx recoiled. “A breach.” Darkness seeped from the splintered column, oozing across the floor towards Aurora’s boots. It smelled of rot and desperation. She stamped her foot. The darkness recoiled
slightly
, but spread again, siphoning motes of light from the air. Isolde chanted, voice rising and falling in ancient cadences. Her words rippled through the hall, pressing against the distortion. Light
flickered
back in from the
shattered
pillar, but the darkness fought to fill the gap. Aurora closed her eyes. She recalled the moment she first felt the pendant’s
warmth
, the trust it offered. She raised the Heartstone high. A
pulse
of deep crimson light swept the hall. It met the darkness mid-stride and held it back, forcing it to writhe and shrink. Nyx seized on that pause. They unfurled like smoke coalescing into form, voice sharper. “Crowd the rift with hope! We must bind it!” Aurora planted the pendant beside the Fae blade on the floor. Light and shadow curled in a furious
dance
between them, sparks of violet and red crackling in the void. Isolde’s chant grew urgent. A tremor ran through the hall. The
crystal
pillars
pulsed
in time. One by one, they flared with inner fire, each containing a fragment of a mortal memory: a child’s laughter, a lover’s promise, a final farewell. Those sounds and feelings, pure and bright, streamed into the breach like rivulets of dawn. The darkness balked. It writhed, then recoiled in a final convulsion. With a thunderous roar, the rift’s edges snapped closed. The distortion collapsed into the archway, folding back upon itself until only the knotwork remained, glowing faintly with residual magic. Silence crashed in the
aftermath
, so complete it pressed against their eardrums. Nyx sagged against a pillar. Their silhouette
shimmered
. “It held.” Isolde lowered her hand, chest rising and falling with relief. “For now.” Aurora retrieved the blade and pendant. She let Isolde slip the gem back around her throat. The blade returned to its sheath with a soft click. They panted in unison, staring down the silent arch. The motes drifted around them again, gentle as moths. Aurora found her voice at last. “What else waits beyond?” Nyx’s eyes glowed faintly. “The prince’s true prize.” Isolde turned to them both, expression
unreadable
. “He hungers for more than souls. He craves memory itself.” A deep rumble rolled through the pillars. One of them
shattered
, shards clattering across the glass floor. Aurora leapt aside. “Not again.” A fissure snaked along the floor towards them, black smoke spilling from its
maw
. The archway’s glow faded, plunging the hall into half-light. Nyx whispered, “We must run—before it consumes the vault.” Isolde’s silver hair swirled as she beckoned. “This way.” They sprinted towards the arch, the polished floor slick beneath their boots. The smoke lunged, tendrils snatching at Aurora’s coat. She slashed with the Fae blade. Moonsilver bit into darkness; it hissed and retreated. Behind them, a pillar exploded, raining
crystal
like deadly rain. Aurora barely dodged a shard the size of her fist. She tasted copper again. Pain blossomed on her arm where glass nicked her skin. Nyx appeared at her elbow. They whispered, tone urgent. “Step through—now.” Aurora plunged through the arch, motes scattering as they passed. The ground heaved behind her. A scream of tearing stone and splintering wood
echoed
through the grove. She landed hard on damp grass, chest heaving. Nyx and Isolde tumbled through after her. She rolled to her feet, blade in hand. The archway’s knotwork glowed one last time, then dimmed to lifeless grey. The stones settled around it, sealing it as though it had never opened. Aurora pressed her blade’s flat against her palm. “That was too close.” Isolde’s lavender eyes glimmered in the grove’s partial
gloom
. “Close will not suffice. The breach will widen again.” Nyx hovered, voice low as wind through dead leaves. “Belphegor will send his favoured hunter. We have mere hours.” Aurora swallowed. The Fae blade’s cold comfort steadied her. She squared her shoulders. “Then we prepare.” A distant crack preceded the sound of hoofbeats—hard, heavy, and
measured
—coming from between the standing stones. A warm amber light bled through the boundary. Aurora met Nyx’s gaze. They nodded, violet glow brightening. Isolde drew a ragged breath. “Time’s swift in here.” Aurora hefted the blade. “Let him come.”
