You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The park gate had no reason to be open at this hour. It wasn’t, not really—rusted chain looped twice and padlocked against the post—but the bars splayed just enough to let a slim person turn sideways and force a hip through. Aurora had known that before she came, as if the knowledge had been left under her tongue the way a word sometimes hung until you said it aloud. Midnight was the agreed time, though of course midnight was only a suggestion. Time, someone had texted from a number that didn’t save, runs like water there. Don’t drink if it speaks. Bring what was given. She’d laughed when the message arrived and then not laughed at all. Now she stood with her back to the cold bars and let the dark steady her. Grass smelled sweet and damp. Somewhere far off, a fox barked, once, twice. The kind of sound that made the air feel thinner. The bad idea registered in her ribs as a flutter, a private metronome beating, this is fine, this is stupid, this is fine. She pulled her jacket closer at the throat. The chain around her neck slid cool against skin. The pendant at its center had warmed on the long walk from the Tube like a coin held too long in a palm. It didn’t throw light, not exactly, but the deep red within it held a hush, the promise of a spark. She took the minor path, the one that bent like a rabbit trail through bracken towards the trees of Richmond. The posted signs bled out behind her. There was no moon to speak of. A smear of the city pressed low on the horizon where the light never died; it only dimmed. Beyond that, there were the trees, the absence of street and brake and horn, and her own inhale loud as rain in her head. “Of all the brilliant plans,” she said, not loud. It sounded like home, the cadence. She’d scraped her accent to a smoother grain when she moved to London, but at night, alone, Cardiff slipped back around her tongue and let vowels lengthen. “And you went with this.” Her phone’s screen lit her hand blue for an instant when she checked it out of habit, an old defense against uncertainty. No signal. 00:00 sat at the top, then blinked to 12:00, then 23:59 and steadied on 00:01. The cheap plastic watch on her other wrist—the one she wore on deliveries, resistant to grease and rain—read 11:48 and ticking. She snorted and put the phone away. Time runs like water there. Don’t drink if it speaks. She knew the Grove by reputation the way she knew Silas’ temper and how many stairs creaked on the way to her flat: by repetition of small details told over pints. A clearing that never quite stayed where you left it. A ring of old oaks so twisted they looked like stones. Flowers that failed to notice winter. She’d been told never to go at night. She’d been told never to go alone. She’d been told a lot of things. That she had come anyway was not bravery so much as momentum. If there were answers, they lived here, and she was tired of letting questions stack like dirty dishes. The trees gathered and the path split and rejoined itself, deer tracks pressed like punctuation into the mud. Once a stag lifted his head from shadow, antlers black as sky against sky, eyes catching what little light there was. He watched her, motionless, the way women learned to walk, always moving, always watching in return. She moved on. The wrongness announced itself in the small ways first. Leaves didn’t scrape in the wind; they clapped a slow, uneven rhythm against each other as if somewhere nearby a pair of unseen hands tried to learn applause. The air cooled by degrees it shouldn’t, a thin winter slipping under the heavier coat of summer. And underneath the sweet green of grass, something else threaded through—the sharp tang of iron, of rain on a railway, of old coins rubbed smooth by too many palms. Aurora stopped just short of the line where the ground broke open into meadow. The standing oaks rose in a broken circle ahead, each trunk thick enough you could not reach both arms around and meet your fingers, each bark ridged like narrows of a river fossilized mid-current. They did look like stones if you let your eyes soften and glance. Between them, the Grove breathed, glittering with wildflowers lifting their small faces even in the dark. Bluebells in a white month, foxglove spires beaded with dew, yellow things she didn’t have a name for. A field guide in her head whispered out-of-season and a nursery rhyme she didn’t like to think of. The pendant grew warm enough to notice without touching. She did anyway, thumb pressing the little red stone. It answered with a faint pulse, a soft thrumming that wasn’t her heart but wanted to be. She hadn’t taken it off since the day the envelope slid under her door. No note. No sender. A thing you did not ask too many questions about in a city where asking was an advertisement that you had something worth giving. “Cute,” she said to the Grove. “I brought it.” Her voice hit the oaks and folded back wrong. There should have been echo. There was repetition, after a pause that lengthened just past comfortable, the sound returning thinner, the vowels oddly rounded, as if her words had gone elsewhere, learned an accent, and come back changed. Cute, the Grove said. I brought it. She descended to the ring with a slow, measured step, rehearsed steps of a courtroom, though she had not chosen that life. The urge to keep counting rose up and she let it. Eight to the boundary. Nine. Ten. She stopped at the eleventh, her toes near the circle’s faint line—not a stone, not a wall; more an agreement that land had made with itself. Something moved at the periphery of vision, low, swift, and gone. She didn’t whip her head toward it. She breathed. Her hands stayed at her sides. Another darted to the left, a ripple that caught starlight and threw it. Mice, she told herself. Fox kits. Things with good reasons to be wary of heavy feet. “Hello?” she tried, because ignoring something never made it go away, and if it was a person she should know that sooner. “If there was a meeting planned, I’m early.” There was a rustle in the wildflowers that did not sound like a body slipping through. It sounded like paper turned slowly, a page at a time. The whisper came after: a child’s laugh threaded thin through leaves, the same three notes repeated exactly, no increase, no decrease. A sound like someone practicing laughter who had heard it only once. A different sound came from behind: the sensation of fingers catching the loose threads on the cuff of her jeans and rolling them between finger and thumb. Nothing touched her. The sensation still crawled along her skin until she wanted to shake like a dog out of water. She clenched her fist around the pendant instead. Heat. A faint glow under her knuckles, crimson as an ember thought better of. “Eva?” she called, though she knew Eva would never. She lived by rules tighter than most of the ones they’d grown up with. She would have walked with Rory to the park gates and set a hand on her shoulder and said, Don’t. Use your head. And she would have been right. But the voice that came from the far side of the ring said in a breathless familiar way, “Rory?” Her name done right. Every letter softened, not the hard-edged Aurora that men seemed to prefer as if more syllables made you more. Rory, the way Eva said it, and then, “I can’t see you.” “Everyone’s a comedian,” Rory said, more dry than she felt. “Prove it’s you.” A pause. Then, crisp as rain against glass: “Ryan’s Gold card fell through a crack in Silas’ floorboards and you elbowed me because you wanted to keep it.” She should not have told anyone that. She hadn’t told anyone that. She’d bought two weeks of groceries for the kitchen with that forgotten glitter of money and refused to feel badly. Her mouth went dry. “I did not—” she started, and then cut herself off. The urge to step over the line rose like a tide. Not a pull in her legs but in the skin at the back of her neck, as if someone was neatly gathering it and lifting. The watch on her wrist read 12:10. Her phone said 22:27, then 04:03. The clouds seemed to thicken and thin in place, too quickly. She felt the Grove like a living thing around her, not a predator but not a friend either. A place that did not care if she, Aurora-now, continued, so long as something measured learned to count differently. She asked the question she had brought here, the one she’d been careful not to say aloud in her flat for fear of inviting ears: “What is it you want with me?” Another movement. Something tall as a lamppost slid between oaks and was not there when she looked full-on. Bones of light and shadow. A suggestion of antlers and then not. The flowers around her had pivoted their small faces—not toward the handful of starlight, not toward the brighter smear of city to the south—but all toward her, a hundred delicate cups upturned to drink whatever she would spill. The scent of salt crowded in on another breath, impossible, thick as the break at Penarth where her father had taught her to judge a good set. She could hear the waves if she chose to hear them, heavy and regular, as if the grove had folded a piece of coast into itself for her particular benefit. It would be easy to go to a sound like that. You could drown in something and never be wet. There, on the deepest edge of the circle, where two oaks leaned together to make an arch like a cathedral gone wrong, the pendant flared warm again. The beat in it quickened slightly, though still soft, a cat behind a door. She looked; she let herself not look directly. At the angle of her eye a line hung in the air, darker than dark, not absence but rejection, like oil on a puddle catching light backward. An anti-seam, if a seam held things. She had no names for it beyond the one the stranger had put in her hand: Heartstone. And the more ancient word skittering like a mouse in attic spaces: Hel. There were doors better left shut. Bridges you never crossed because you had learned what waited. The oak beside her creaked in a voice. It was only bark stretching, wind working the ancient joints, but the sound did not slide past as harmless noise. It settled on the shape of a sentence not meant for ears. She took a step back without meaning to and knocked her heel against a stone that had not been there a moment before. Her mind knew where she had come in. Her feet did not. “I’m not playing games,” she called, softer because the air did not need big words. “You wanted me here. I’m here. But you’re going to have to do more than party tricks.” “You’re here,” the Grove said back, slack and stretched. Malphora, someone whispered, so faint she almost wrote it off as nerves. Not a name she wore in any world she claimed. A name someone had tried on her, once, in a half-dream or a threat. It had weight in it she didn’t want. Her left wrist itched, the old crescent scar pulling tight like new skin. She dug a nail into it, hard, and welcomed the sharp lance of sensation through air thick as syrup. Small pain, old reality. Ten, eleven, twelve. She counted petals on a daisy the size of her thumbnail, because a woman had once told her, There’s power in simple lies we make true. He loves me. He loves me not. He loves me. He— “Rory.” Softer from the arch. Not Eva now, someone else. Brendan Carter’s rounded baritone. The smell of his shaving soap rose up with it, a cheap lemon he’d always insisted did the job better than expensive things. “Come on, a stór. You’ll catch your death.” “You’re not my father,” she said. The words cut to the right length. She kept her feet where they were. A lit shape threaded between the flowers, pale and hand-high, a moth or not a moth. It drifted near her knee, hung, pulsed once with its own light, and then unraveled into ash that fell without touching the ground. The ash hung in the air like dust in sunlight, but there was no sun, nothing to catch it. Her skin tightened, a map of chemical signals firing off, alert alert alert. The standing oaks felt nearer. The circle seemed small as a room. She turned slowly, eyes half-lidded to catch movement without chasing it. If this was a door, it was also a mouth. If it wanted something from her beyond the pendant, she did not want to find out what shape she made in the teeth. “You called me for the stone,” she said to the seam without looking at it. “Here’s your look. That’s all you get.” The pendant was not made to be an answer. It was a key or a warning. In her palm it grew warm again, the glow from within not raw light but a sense that light waited just under skin. If she held it out like a badge, the wrongness around her edged back, not with fear, not with anger, but with interest sharpened to points. The line at the arch quivered once, almost imperceptibly, like a thread in a weaver’s shuttle drawing taut. Something leaned its weight against the other side. She felt pressure in the air, in her jaw, in the small bones of her ears. She could have sworn she heard breathing. Not one set, several. The patience in it made her want to run in a way nothing had, not even the sound of Evan’s key in a lock years before. Evan had been a bad decision with a human face. This was old. This was law. This did not care what name she used on taxes. A wind moved across the Grove, but it did not bend the flowers. It only lifted the hair along her arms. At the edge of hearing, someone else whispered, “Soon.” Her name followed as a question and a promise both. Aurora. Rory. Laila. Malphora. Each thrown like a coin into a well to see which clinked. She moved. Not a run, not a bolt. The careful, steady exit of a person leaving a room where a bomb ticks, where any suddenness might be read as invitation. One step. Two. With each, she counted. She let her hand rest over the stone. The warmth taught her where the pressure increased, the way a person running blind learned to hear rooms by how their breath bounced back. Her heel found the stone that hadn’t been there and she avoided it without looking down. The oaks straightened. Or she did. The laugh—the one made of three repeated notes—flattened into silence. Something long and narrow, like a single reed on a riverbank, brushed the back of her knee and did not leave water behind. She did not grant it a reaction. She kept moving, eyes on the not-place where she had stepped in. It wasn’t there and then it was, a slim seam in the circle where the pressure thinned. She slid through it the way she had slid between the bars of the gate. The instant she stepped onto the path, sound came back in layers. The fox barked again, real or remembered. Distant traffic admitted itself into the edges of her hearing. The field behind her breathed and let her go. She did not look back at once. The Grove did not like it when you behaved as if you had choices. She walked until the flowers ended and the bracken began and let herself breathe out then, a slow purposeful exhale that hadn’t found room in her chest until now. She put a hand on a real tree—beech, smooth-skinned and unblemished save for a single heart carved deep by bored hands long before. J + D, the letters insistently mundane. She could love those letters; they kept the world together. When she finally turned, the clearing had already shifted. It sat a fraction to the left, or her eyes did. Between two oaks now, within the arch where the darker line had hung, there was only a fence of shadow. No seam. No sense of weight pressing. The pendant at her throat cooled to something just warmer than skin. She lifted it and watched the red in it slow its beat, faint and stubbornly alive. Her watch read 03:12. Her phone said 21:17. Her breath made small white ghosts in front of her face though the night had not earned its frost. She might have laughed if her mouth hadn’t forgotten how. Instead she touched the old crescent scar at her wrist and pressed until the ache grounded her again. “Not tonight,” she told the trees under her breath, to the seam that might be and might not be, to the someone who had used her name and her father’s voice and the scent of brine to unhook her from herself. “Find another key.” It was bravado. It did not matter. Saying it made her more herself than standing quiet and waiting to be told her edges. On the way back, the wrongness did not vanish altogether. It lapped at her ankles like small waves, like a pet dog that had trailed her for blocks waiting to see if she would turn, waiting to see if she would drop something that could be fetched. The stag lifted his head again as she passed and this time dipped it in something that might have been acknowledgement. Or it might have been hunger. That was the thing about stories: they didn’t care which you chose. At the gate, she did not fit through as easily as she had before. For an instant she felt hands—not touching, never touching—measuring the seam of her, counting the ribs of her cage, learning her dimension by the way the air lay down on her bones. The fence bars left metal cold along both arms as she squeezed. Then she stood outside the park, on a pavement scattered with a new fall of leaves she could not name and a light the color of old tea pooling under a lamp that had not been on when she arrived. Somewhere, a night bus sighed and shouldered past. A man on the far side of the street coughed three times and kept going. The ordinary world, loud in its own ways, insisted itself. Aurora looked down at the pendant in her palm. The faint glow in its heart felt like a promise backed by an old patience. The crimson seemed a shade darker than before, as if it had learned a new word and tucked it away not to be forgotten. She closed her fingers around it. “We’re going to have words,” she said to the empty street, and turned toward home. The park gates creaked a very slow apology she did not accept. Somewhere behind her, where the world warped, a voice that might have only been leaves found that three-note laugh again and failed to make it sound true.
