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 hit the stone hard
enough to knock the breath from her lungs.
Her palms slid over something
slick and sticky, sweet on her skin.
She pushed herself up with
a curse, hands leaving faint red smears on pale
marble
. "Next time," she rasped, "I go through first on my own terms."
Nyx unfolded from her shadow
like ink peeling off the ground.
Their violet eyes glimmered in
the half light. "Next time,"
their voice rustled against her
ear, "you learn to land."
Aurora wiped the sticky residue
on her jeans and then paused, frowning.
It clung like syrup, but
when she lifted her fingers to her nose, the scent punched through her. Wine, spiced and rich. Under it, a sour note of rot.
She turned in a slow
circle.
They stood on a wide
terrace carved out of pale stone, each flagstone veined with faint crimson. Low walls rose at the edge, carved with reliefs of open mouths, tongue and teeth pickled in stone. Beyond the balustrade, terraces stepped down and down into a hazy depth, each one swallowed by coiling vines.
The vines carried fruit the
size of skulls.
Clusters of swollen grapes hung
heavy, skin stretched thin over shifting shapes.
Some glowed from within like
banked coals. Some twitched. Aurora swallowed. "This is Dymas," she said. "It is a corner of it," Nyx said, "the old roots. Before the feasts, there were cellars."
The Heartstone under her shirt
beat a hot, eager
pulse
against her chest. Not quick, not frantic. Slow. Hungry.
Each throb answered by a
faint shimmer that ran through the air, as if the world itself breathed with it. "You sure this is the right place?" Aurora said. Nyx tilted their head.
Their edges blurred, then sharpened
again. "Your trinket thinks so."
Aurora wrapped her fingers around
the pendant through the fabric.
The gem burned against her
palm like a coal but did not blister. It never did.
It only reminded her she
was made
of meat. She glanced back. The arch they had fallen through still stood behind them, wedged between two huge stone urns. On this side it looked less like an opening and more like a crack in a painting. A vertical smear of wrongness that ate the light around it. Through it she saw a flash of green, the hint of Isolde's grove, then the shimmer thickened. The view narrowed, like a throat closing. Aurora stepped toward it. The Heartstone flared, sharp enough to sting. The crack in the air convulsed, then smoothed over, solid as glass. The way back vanished. She stared at smooth stone. "Well," she said, "that answers that." Nyx drifted closer to where the portal had been.
Their hand met the air
and sank a fraction, then stopped. They pushed harder. Nothing yielded. "The Veil stitched behind us," they whispered. "Someone wanted you in." "Not out." Aurora's shoulders tightened.
She released the pendant, dug
into her jacket and closed her hand around cold moonsilver instead. The Fae blade slid free with a
whisper
. Light caught on its leaf-shaped edge and shivered.
She felt its cold climb
up her wrist, into the scar on her left hand, settling there like frost. Nyx's gaze lingered on the dagger. "Careful where you wave that, little mortal." "You invited me to Hel," she said. "You get the full package."
She turned away from the
sealed wall and looked out across the terraces. Down below, something laughed. A low roll of amusement that skated over her skin like oil. It did not sound near. It sounded everywhere. Aurora
tried to
map a path with her eyes. The terraces spiralled, sometimes wide, sometimes narrow, linked by short staircases that curved out of sight behind banks of foliage. There were no rails. The drop between levels grew steeper the lower they went, until the vines at the bottom merged into a dark, glossy mass. From above it looked still.
Then the surface trembled, like
muscle under skin. A door waited on this terrace, set into the inner wall behind them.
It wore no handle, only
a relief of a closed eye. Nyx nodded to it. "Cellar first," they said. "The vines are for later." "The vines look like they eat people." Nyx's smile flashed, a cut in shadow. "Later." Aurora moved to the door. The stone around the carved lid was slick with the same crimson sheen that coated the floor, as if someone had poured wine or blood until it overflowed and dried in glassy sheets. She pressed her free hand against the lid. "I suppose knocking is polite." The stone under her palm warmed, then twitched, dry eyelid shivering. It cracked open a fraction. A sliver of gold stared out at her, pupil a narrow pit that drank her reflection. Aurora froze. The pupil widened. The lid pulled itself fully open. No socket, no flesh, only a
perfect
round eye set into the slab, staring without blinking. Threads of faint script spidered out from the iris, curling over the door in unseen ink. Her Heartstone flared. The script erupted into visible heat,
searing
lines of red that circled and twisted into knots. Wards. Aurora tightened her grip on the dagger. The blade hummed in her hand, distant but definite, like a note she felt in her bones. "That one," Nyx murmured, "unravels such things." "It's what Isolde said," Aurora answered. "Cut between the words, not through them." She brought the blade up. The eye tracked the motion, pupil shrinking. Aurora sucked in a breath, centred herself, and thrust. The dagger bit the air an inch from the stone. No resistance, no impact. Yet the wards screamed. Lines of red snapped and whirled back from the point, curling like severed tendons. The scent of hot metal and old incense flooded her nose. The Fae blade slid forward another inch. The wards tore open around it. The eye burst,
not with fluid but with a sharp crack of shattering glass
. Golden dust blew out, hot against her face. She flinched and brought up her arm. Grit stung her cheek. When she opened her eyes, the door had changed. The relief had gone. The stone now showed a shallow recess, shaped like a handprint, every finger too long, the palm wide as both of hers together. Nyx stepped closer. "Gluttony opens to those who give." Aurora shot them a look. "You first." "I am hollow," Nyx said, almost amused. "Hel will not waste a door on me." She stared at the print. The Heartstone pounded. Her own
pulse
climbed to meet it. Blood or touch, she wondered. Both, probably. Rory, you have terrible hobbies. She took the blade to her own palm before she could think herself out of it. The moonsilver kissed her skin. Cold bit, then hot pain split over it. Blood welled up, dark and thick. She pressed her hand to the waiting stone. It drank. The recess swallowed her palm, then her fingers, then more. She yanked, but the stone clung, smooth as a throat. The Heartstone erupted in heat. For a second she felt every beat of her heart like a hammer. The terrace around her blurred. The scent of wine grew strong enough to choke. Nyx's shadow lapped at her ankles. "Steady." The stone let go. She staggered back, clutching her hand. The wound had already closed, pale line pinking her palm. The blood she had given now
traced
thin veins through the door, weaving through the faint script like knitting. The slab split down the middle and sighed inward. The scent buried her. It rolled out in a heavy wave, layered and deep, like stepping into a restaurant kitchen with every burner on. Roasted meat, caramelised sugar, charred spice, fresh bread, sour vinegar, and behind it, under it all, the unmistakable sweet-sick reek of decay. The smell of a feast left too long to itself. Aurora gagged. "Welcome underground," Nyx whispered. They stepped through. The cellar felt carved out of bone. White arches curved over their heads, ribbed and elegant. Each column between them swelled with carved reliefs,
not of saints or kings, but of feasts
. Stone tables groaned with frozen platters, every dish depicted mid-spill, gravy frozen as it poured, fruit solid in the act of bursting. Hanging from the ceiling, rows of pale shapes rotated
slowly
on invisible hooks. At first Aurora took them for sides of meat.
Then one turned and she
saw a face. Human, eyes closed, expression slack in some old, private ecstasy. The bodies had no seams, no marks, no decay. Skin smooth and blank where mouths and noses should be. Her
stomach
clenched. Nyx glanced up, their expression
unreadable
. "Belphegor's reserves. Souls pickled for later." Aurora kept her eyes on the floor. Barrels lined the walls in endless rows, stacked three high. Some bulged. Some sagged as if something inside shifted. Each had a tap shaped like a small, gaping mouth. Thin trails of liquid had leaked from a few, dried into glossy streaks. From deeper in the cellar came a low, slow drip. A ponderous heartbeat of sound. The air
quivered
with it. She heard no voices. No clatter of plates or murmur of diners.
Only the drip and the
soft, almost inaudible hum of the hanging bodies turning. "This place doesn't get visitors?" she said, her voice hushed despite herself. "Not living ones," Nyx replied. "Hel does not waste the good wine on mortals." The Heartstone tugged her left. The pull
felt like a hook under her ribs
. Aurora followed. They walked between the barrels, the soles of her boots sticking
slightly
to the floor with each step. On some casks, symbols had
been carved
, rough and sharp. Talons had done this, or teeth. Circles within circles, jagged crescents, little clawed hands. The tug in her chest grew stronger. "Rory," Nyx said, "notice the way the walls breathe." She stopped. At first she heard only the drip.
Then, under it, a faint
rustling, a stretch and relaxation. She stepped closer to the nearest wall and laid her uncut palm against it. Stone met her touch, cool and smooth.
Then, after a breath, it
gave, almost imperceptibly.
As if something vast and
sleeping inhaled on the other side. She pulled her hand back. "That is not
comforting
." "It should not be," Nyx said. "You walk in the flesh of a sin." She gave them a flat look. "Cheery." They smiled. "You were the one who said yes." The Heartstone flared again, impatient now. Aurora kept going, shoulders tight, trying not to think about what might wake if she trod too hard. They reached an opening where the barrels broke around a circular pit. The floor here sloped
gently
inward, like the bottom of a drained fountain. In the centre, a metal grate covered a hole wide enough for a person to crouch in. The grate had teeth.
Not sharp, not animal, but rows of blunt molars
and incisors, pressed together where metal should have
been, grown
into a
perfect
circle of clenched jaws. From between them seeped a slow, dark trickle. Wine. Or blood. Or both. Aurora's pendant beat hard enough to hurt. Nyx crouched at the rim of the pit, shadows pooling around their feet. "Portal throat," they said
softly
. "Dymas keeps its gates like this. Fed, never sated." Aurora peered down. The trickle slid over the teeth and vanished between them. No light glimmered below, only an endless, patient dark. "This is what it called me to?" she said. "The Heartstone knows its source," Nyx said. "Belphegor made it from the same seed. A promise of passage." "And the bit where we don't get eaten alive?" Nyx's eyes lit, faint violet reflecting in the dark liquid. "That, little mortal, depends how politely you ask." She stared at the jawed grate. "Ask how?" Nyx's form shifted, edges loosening. They leaned closer to the ring of teeth. Their voice slipped thinner, threading down between the enamel. "Old hunger," they hissed, "wake and listen." The cellar answered with a low, long groan. The drip from the hidden
depths
faltered. Aurora's grip on the dagger tightened. The teeth twitched. Nerves prickled along her arms. She stepped back a pace,
weight
light on the balls of her feet. Nyx continued. "A daughter of Earth carries your
echo
," they whispered. "Stone-heart, seedling of Dymas, returned to the root. She asks safe crossing." The grate shuddered. Teeth ground against each other, scraping. The sound set Aurora's own on edge. From the hole below surged a rush of scent, sharp and cloying, like opening an old bottle of syrup that had turned. Something answered them. Not in words, not in any tongue she knew. A feeling, heavy and hungry, pressed against her thoughts. It tasted of ripe fruit about to split, of tables collapsing under their own
weight
. It touched the Heartstone and delighted in it. Her knees nearly buckled. She dug the point of the dagger into the floor to steady herself. "No bargain," she bit out through her teeth. "No deals." Nyx's head snapped round. For a moment their eyes looked almost human,
something like alarm flickering there
. "It hears what sits in your bones," they said. "Careful." "Then it hears 'no'," Aurora said. "Loud and clear." The presence pressed harder. It did not understand refusal. It knew need, and offering, and giving in. The Heartstone rose hot and heavy against her breastbone. Aurora yanked it free of her shirt with her bleeding hand. The chain bit into her skin. She held the pendant out over the grate. "You want this,"
she said, voice rough
. "You take us through first. All the way. Then we talk about ownership." The gem burned in her palm, fierce and steady. Light leaked from the cracks in its surface, deep crimson, spilling over her fingers and dripping like molten glass. The teeth parted. Not wide. Not enough to climb through. But enough for the dark between them to gaze up. Aurora stared back, jaw tight. "Nyx," she said, "tell me when this looks like 'yes'." The Shadowshade did not answer at once. Their outline
wavered
. "Aurora," they breathed, "step away from the edge." She heard it then. A new sound, thin at first, then rising. A soft rustle from above, not from the pit. Skin creaked on hooks. Chains she had not noticed chimed against each other. Around them, the hanging bodies turned. Their blank faces angled down, one by one, like flowers seeking the sun. Mouths that had not been there drew themselves open in their skin, little slits peeling wetly. Teeth budded in the new gaps, pushing through pale flesh. Every soul-pickled body in the cellar watched her and the Heartstone, eyes still sewn shut, mouths widening. The grate below yawned another inch, breath hot and wet against her hand. The nearest body
trembled
, then ripped itself free of its invisible hook with a twitch like a fish on a line. It plummeted towards her, mouth gaping, limbs unfolding mid fall. Aurora wrenched the dagger up as the first of Hel's preserved came screaming down.
