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.

A character is alone in a strange, isolated place at night. They came here for a reason, but something feels off from the moment they arrive. The wrongness builds slowly — sounds that shouldn't be there, things that move at the edge of vision, a growing certainty that they are not alone. Build tension through restraint, not through gore. Use the codex entries above as your world reference for the character and setting. Only include the prose of the scene without any markdown or commentary.

uate the silence. (Okay, writing now.) The air inside the boundary tasted different, thick with the scent of blooming jasmine and damp earth, though it was November and midnight in Richmond Park. Aurora Carter stepped past the ancient oak standing stones, the rough bark scraping against her sleeve as she crossed the threshold. The noise of London, the distant hum of the A307 and the rustle of normal night creatures, vanished instantly. It
was replaced
by a silence so absolute it felt like pressure against her eardrums. Rory pulled her jacket tighter around herself. She was five feet six inches of nervous energy wrapped in black denim and delivery leathers, but she forced her breathing to slow. Panic was useless. Panic got you killed, or worse, sent back to Evan. She touched the small crescent-shaped scar on her left wrist, a habitual grounding mechanism, before her fingers found the silver chain at her throat. The Heartstone pendant lay against her sternum, cold at first. Then, as she moved deeper into the clearing, it
began to
pulse. A faint warmth spread through the deep crimson gemstone, roughly the size of her thumbnail. It was the reason she was here. The unknown benefactor who had slipped it into her pocket weeks ago had given no instructions, only a
warning that it
would glow when the veil was thin. It
was glowing
now, emitting a faint inner light that cast sickly red shadows against the wildflowers blooming at her feet. They were wrong, the flowers. Violets and poppies sprawled across the grass, vibrant and open despite the lack of sun. They shouldn't exist here. Nothing about this place respected the rules of the earth she knew. Rory stopped in the center of the grove. The pendant grew hotter, burning
slightly
against her skin. She looked around, her bright blue eyes scanning the tree line. The oaks surrounding the clearing stood too still. There was no wind, yet the leaves
trembled
. She checked her
watch
. The second hand
was spinning
counter-clockwise, a blur of motion. She tapped the glass face, but it didn't stop. Time moved differently here. An hour inside could be minutes outside, or days. She had told Silas she would be back before
closing, that she
needed to drop off keys for the flat above his bar. If she stayed too long, she might return to find weeks had passed. Or she might not return at all. A snap of a twig came from her left. Rory froze. She turned
slowly
, her hand dipping toward the pocket where she kept her pepper spray, though she doubted chemical irritants would work on whatever lived in a pocket between Earth and the Fae realm. Nothing was there. Just the wildflowers and the dark trunks of the trees. She exhaled, a white plume in the cold air. You are alone, she told herself. You are just jumpy. It is the job. It is the delivery runs in the dark alleys of London making you
see
things. Another sound. A shuffle, like fabric dragging over grass. This time from behind. She spun around. The pendant swung with the movement, the crimson light flaring brighter. The warmth was becoming uncomfortable, bordering on painful. She knew the artifact's behavior; it pulsed when near a Hel portal. She had assumed the Grove itself was the anomaly, but the heat suggested something else was here with her. Something opening a door. The shadows between the trees

med to lengthen, stretching toward her like fingers. They moved independently of the light source. Rory took a step back, her boot crushing a patch of white clover. The scent was overwhelming, cloying, like perfume used to mask decay. She needed to leave. The cool-headed intelligence that had helped her
navigate
law school before she fled Cardiff, that had helped her escape Evan without a trace, screamed at her to run. But her feet felt heavy, as if the gravity in the Grove was stronger than outside. Do not run, she thought. Running triggers the chase. She stood her ground, forcing her muscles to unlock. She

ed the tree line. The silence had changed. It was no longer empty; it
was holding
its breath. A whisper brushed against her ear. It sounded like her name, but distorted, as if spoken through water. Rory. She didn't turn. She kept her eyes on the shadows ahead. I am not alone. The certainty settled in her gut, cold and hard. There was something standing just outside her peripheral vision, shifting whenever she
tried to
look directly at it. The pendant burned now. She could smell ozone and burnt hair. The crimson glow illuminated the immediate area,
revealing that the
wildflowers nearest to her
were wilting
rapidly, petals turning black and curling into ash within seconds of the light touching them. She reached up to unclasp the chain, to drop the artifact, but her fingers wouldn't obey. They hovered over the silver link, trembling. The air pressure dropped, popping her ears. The shadows coalesced into a shape taller than a man, thin and elongated, standing just beyond the ring of oak stones. It had no face, only a smooth surface where features should be, yet she felt its attention fixed on her with predatory intensity. Rory swallowed the lump in her throat. She thought of her mother in Wales, her father in Cardiff, the life she had left behind to survive. She thought of the flat above Silas' bar, the safety of the mundane world. The shape took a step forward. The grass beneath it did not bend. She forced her hand down from her neck and took a deliberate step backward, then another. The movement

med to agitate the air. The whispering grew louder, a chorus of voices now, overlapping, speaking in languages she didn't know but felt in her teeth. The pendant gave a final,
searing
pulse. The light flared blindingly bright, turning the grove into a
stark
negative image of black and white. In that flash, she saw them. Not just one. Dozens of shapes standing among the trees,

ing. Waiting. Then the light died, plunging her back into darkness. The warmth vanished from the stone, leaving it cold and dead against her chest. The silence returned, heavier than before. Rory did not wait to
see
if they would move again. She turned and walked, not ran, toward the gap in the standing stones. She kept her eyes forward, ignoring the sensation of hundreds of eyes tracking her retreat. She stepped past the ancient oak boundary, and the noise of London crashed back into her world—the distant traffic, the wind in the normal trees, the cold bite of a normal November night. She stood on the other side of the stones, her heart hammering against her ribs like a trapped bird. She looked back into the Grove. The wildflowers
were gone
. The clearing was just grass and dirt, dark and empty. But the pendant remained cold, and the scar on her wrist
throbbed
in time with her pulse. She zipped her jacket up to her chin and walked away into the night, knowing with absolute certainty that the silence had followed her out.
