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>

Rory hit the floor hard
enough that her teeth clicked.
Stone, smooth and warm, not
London concrete.
The air tasted of burnt
sugar and fat.
She rolled to her knees
and yanked her arm out of the closing tear before it scissored shut with a sound like cracking bone.
The Heartstone pendant on her
chest burned against her skin, crimson light leaking through her shirt. Nyx flowed through after her, a black smear peeling itself from the rift a heartbeat before it vanished.
The shadow-body stretched tall, then
condensed into something roughly human. Their violet eyes thinned. "You choose charming doors,"
their voice whispered from everywhere
and nowhere at once.
Rory spat the sweetness from
her mouth and pushed to her feet. "You said we needed Hel," she said. "This is Hel. Congratulations. We can both hate it."
She brushed dust from her
jeans and finally looked up.
The hall wrapped around her
like the inside of a gigantic ribcage. Pale, curved beams arched overhead, each rib carved with swirling reliefs of feasts.
The carvings moved, slow and
sticky. Tiny figures lifted goblets, ripped meat with their teeth, poured sauces that ran off the stone and bled down the wall.
Their faces blurred when she
tried to
focus. Between the ribs, the ceiling glowed a soft amber, the colour of old whisky held up to the light.
It did not come from
lamps or bulbs.
It seemed to leak from
the air itself.
Rows of long tables cascaded
down the hall in terraces, all pointing toward a raised dais at the far end. Every table groaned under dishes. Steaming bowls, towers of fruit, platters of glazed meat,
crystal
decanters filled with wine that smoked faintly at the rim. No diners. Just the food. Fresh, impossibly so. A roast bird still crackled, skin blistering in slow, lazy pops. Rory felt her
stomach
contract. She had eaten hours ago. London hours. Her body did not care. "Smell that," she muttered. Nyx lifted their head. Shadows rippled over the nearest table as if they pulled in the scents. "Salt, sugar, marrow, fear," they said. "Dymas. Prince Belphegor has a fondness for old dining rooms." "Lovely neighbour," Rory said. The Fae-forged dagger strapped at the small of her back lay cold against her spine, colder than usual.
It felt like a line
of ice. The Heartstone
throbbed
, a slow
pulse
in time with a heartbeat that was not hers. Rory clasped it through her shirt and hissed as it scalded her palm. "All right," she said. "It wants us moving."
She stepped to the nearest
table.
Her boots left no footprints
on the stone floor, which made her skin crawl more than if it smeared like fat. A silver platter held something that looked almost like a rack of lamb. The flesh
shimmered
pearl white, marbled with veins of ruby. "Don't," Nyx breathed. Rory raised an
eyebrow
and picked up the serving knife. "Just looking." When the knife touched the meat, the entire rack shivered. A tremor ran through it. The flesh knitted over the line she had
started to
cut, sealing itself with a wet squelch. A small moan gusted from the platter. Rory put the knife down. "Right," she said. "Alien fridge logic. Got it." She backed away. Heat rolled from the table in waves, thick with spice and smoke. It clinged to her clothes, wormed under her skin. Nyx drifted beside her, their edges blurring, tugged by shadows that did not belong to them. Every candle flame in the room, every deep dish and chair leg, threw a shadow that twitched toward the Shade, as if drawn. "You feel that?" Rory said. "We stand in a mouth," Nyx whispered. "It breathes through us." "Encouraging." The pendant
pulsed
again, stronger, tugging against her neck like a fishhook. The dais at the far end waited, blurred by distance. The hall stretched longer than it should.
She could not tell if
the steps between them and that raised platform numbered fifty or five hundred. "That altar," Nyx said. "It remembers your stone." Rory snorted. "Everything remembers this bloody thing."
She started down the central
aisle. As they walked, the hall changed. Subtle shifts at first. Platters emptied when she glanced away, then refilled with different delicacies. Wine darkened, ripened, the scent going from fruity to heady to sharp vinegar as they passed.
She heard faint sounds, just
under hearing. The clink of a fork, the scrape of a chair. Quick breaths between bites. Rory refused to look over her shoulder. Nyx's rule about chases in Covent Garden applied here, portalled dining hall or not: do not look back. Halfway down, something brushed her ankle. She almost kicked on reflex. Her muscles locked in time. A small, white hand protruded from under the tablecloth. Child-sized, fingers plump, nails painted with something that glittered like ground pearls. The hand patted the air until it met her boot and then explored the leather, curious, possessive. Rory swallowed. "Friend of yours?" she murmured. Nyx watched the hand without blinking.
Of course they did not
blink. "It eats what falls," they said. "Bones, scraps, careless visitors." The hand reached for her laces. Rory stepped sideways. The hand groped after her and closed on nothing, then withdrew under the cloth. The sound of chewing followed, wet and hungry. She walked faster after that. The walls pressed inward the deeper they went, the ribs closer, the carvings more
chaotic
. Scenes of banquets blurred into orgies of consumption. Mouths devoured plates, cutlery, the table itself. Diners merged with dishes, their limbs baked into pies, their eyes floating in soup bowls. Her skin prickled. Each carved mouth
seemed to
turn as she passed. "This place is empty, you said," she muttered. "I said forgotten," Nyx replied. "For Hel." "Split hairs later." Steps rose before them, shallow and wide, leading to the dais. The stone here glistened as if freshly licked. Atop the dais stood a single, massive table set for one. The chair towered, carved from a single block of bone, polished smooth by centuries of use. It faced them, tilted back, expectant. On the table lay no feast.
Just a single object on
a black
velvet
runner. A stone. Deep crimson, the same shade as the Heartstone on Rory's chest, but larger. Heart-sized. It
throbbed
with slow light. The pendant against her skin answered. Rory stopped at the base of the steps. Sweat trickled
down her spine
,
chilled
as it hit the dagger's hilt. "That looks like a terrible idea," she said. Nyx's shadow-body
shimmered
, thinning at the edges. The pull on them grew stronger. A tide. "Prince Belphegor cut the first hunger from the Veil and hammered it into that core," they murmured. "The Heartstone fed from it once. A seed." "Great," Rory said. "So we are in the kitchen of the person who grew the thing around my neck." She took the steps one by one, boots leaving faint streaks where the stone stuck and let go, stuck and let go, as if reluctant to release her. At the top, she stood level with the table. The larger stone
pulsed
. The pendant dragged against her collarbone, desperate, eager. "Feels like bringing a toddler to a chocolate factory," she said. "It remembers its first taste," Nyx whispered. "You are not helping." Rory took the Heartstone in her hand. The metal chain bit into her fingers as the gem flared. Heat spilled from it, harsh and dry, tasting of scorched sugar. She lifted it toward the larger stone. The air thickened. The hall
seemed to
inhale. Everything stilled. No pops of roasting meat, no quiet chewing, not even the faint scrape of silver on
porcelain
from unseen hands. Silence pressed on her eardrums. "Last chance to back out," she said. She touched the pendant
to the core
. Light punched through her. Crimson burst out of both stones, a blinding flare that carved the world down to red and white. Her eyes watered. Her bones rang like struck glass. The hall groaned. The carvings on the ribs convulsed. Stone diners clutched their throats, mouths open in silent screams. Wine bled thicker from the walls, dark as clotted blood. Rory staggered back, yanking her hand away. The pendant ripped free of her fingers
reluctantly
, as if it had found home and fought to stay. The larger heartstone beat. Once. Twice. A third time. With each
pulse
, the tables below them shifted. Chairs slid themselves into place. Plates
aligned
. Napkins folded and unfolded like breathing lungs. Figures
wavered
into being around the tables, outlines first, then details, as if painted by a hurried hand. Some had horns, some too many teeth, some nothing human at all besides the jaws. Eyes opened everywhere. They all looked up at the dais. At Rory. Her breath hitched. "Nyx," she said. "Yes." "You said forgotten." "I did." "By whom?" Nyx's eyes glowed brighter. "The Wardens can no longer track this room. That is not the same as abandoned." The nearest figure at the closest table solidified. A tall demon with goat's horns curling back over its skull, cheeks stained with old wine. It licked its lips and reached for a goblet that had not been there a moment ago. The scent of fresh blood hit Rory's nose like a blow. The Fae blade burned a cold line against her back. She eased it from its sheath. The moonsilver dagger slipped into her hand, light sliding along its leaf-shaped edge like water over ice. As it cleared the leather, the air around them hissed, as if it disapproved. Every demon in the room recoiled a fraction,
not from her, but from the weapon
. Whispers rose, thick, hissing. "Fae," someone breathed. "Thief," another voice rumbled. The great stone heart on the table
pulsed
faster, mirroring the spike in Rory's own chest. The pendant on her chain answered in frantic rhythm. Shadows crawled across the floor, drawn toward Nyx. Their humanoid outline buckled. Something tugged on them from all sides, like meat hooked by too many forks. Nyx's edges tore in tiny strips that snapped back with effort. "They want me on their plates," they murmured, sounding almost amused. "They always wanted, little sorcerer." Rory did not look at them. "You can hold together," she said. "You promised." "I promised to try." "You promised,"
she repeated, harder
. Silence from Nyx, which, from them, meant consent. A chair scraped across stone below. Another.
Then a hundred more, a
wave of sound as the assembled company rose to their feet. The massive bone chair at the head of the table creaked. Someone sat who had not been sitting before. Rory's mouth went dry. He looked almost human. A tall man in a heavy, old-fashioned black coat that had never known dust. His hair fell in dark, slick curls to his shoulders. His skin glowed with the warm flush of someone who enjoyed rich food too often, his cheeks full, his lips red. His eyes ruined it. They burned amber, the same hue as the strange ceiling light, and deep in their centre spun tiny, endless plates. He smiled at Rory with the ease of a host greeting a late guest. "At last," he said. His voice rolled through the hall like smoke, filling every corner. "My little Heartstone comes home. And it brings a girl wearing a Fae toy." Rory clenched the dagger so hard her knuckles ached. "You are Belphegor," she said. "It eats," Nyx murmured. Belphegor tilted his head, considering her. "Aurora Carter," he said, tasting each syllable. "No. That is the name you wear above ground, in the thin air. The one you kept under your tongue as a child fits better." He leaned forward. "Malphora," he said. The name hit her like a slap. The pendant blazed against her sternum. Every demon in the room leaned closer, nostrils flaring, teeth
glinting
. Nyx's form shuddered. The shadows pinning them down tightened. "Do not answer," they rasped. "Do not give him your voice." Belphegor laughed, rich and delighted. "You cross my threshold with stolen hunger and Fae steel," he said. "You wake my table. You will give me more than your voice before we finish." The floor beneath Rory rippled. The smooth stone softened to something with give, like the top of a baked crust about to break. Fine cracks spidered out from under her boots. From each crack, something pale and wet pushed upward. Tongues. Dozens of them, slick and pink, tasting the air, questing for her ankles. Rory sprang back. The first tongue lashed where her foot had been and hit the bone of the step with a fleshy smack. It recoiled and then lunged again, quicker. The entire dais
quivered
. The great heartstone hammered light into the room now, each
pulse
sending a fresh wave of movement through the crawling tongues. Belphegor spread his arms wide, benevolent. "Sit," he said. "Eat. You came so far. It would be rude not to begin." The tongues surged toward the steps in a slippery tide, and the nearest demon vaulted the table with a roar, claws outstretched, aiming straight for Rory's throat.
