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.

The air inside the boundary tasted different, thicker, like ozone and crushed petals. Aurora Carter stepped between the ancient oak standing stones, the rough bark grazing her arm as she passed. She paused, letting her eyes adjust to the gloom. Richmond Park
was closed
at dusk, but the Grove did not obey council hours. It did not obey much of anything. She touched the silver chain at her throat. The Heartstone pendant rested against her collarbone, usually cold as a river pebble. Tonight it hummed. A faint warmth radiated from the deep crimson gemstone, pulsing in a rhythm that matched the thud of her own heart. She had come because the stone had burned hot enough to leave a mark during her shift at the Golden Empress, forcing her to abandon a stack of noodle boxes and flee into the night. The benefactor who gave it to her had offered no instructions, only a
warning that it
would sing when the veil thinned. Rory scanned the clearing. Wildflowers bloomed in the darkness, impossible bursts of color against the grey turf. Bluebells and poppies opened wide despite the lack of sun, their petals unnaturally vibrant. They should be closed. They should be sleeping. The silence of the park outside
was gone
, replaced by a low, vibrating hum that she felt in her teeth rather than heard with her ears. She took a step forward. Her boots sank into the grass, but made no sound. No crunch of earth, no rustle of blades. That was the first wrong thing. The second was the shadow cast by the standing stones. They stretched toward her, long and thin, though the moon was high overhead. Shadows should fall away from the light, not reach for the observer. Rory forced herself to breathe. Panic was a luxury she could not afford. Not after Evan. Not after everything that had chased her from Cardiff to London. She was twenty-five years old, not a frightened child, and she had a mind that solved problems for a living. She assessed the situation. Objective: Determine the source of the pendant's reaction. Obstacle: The environment
was behaving
inconsistently with known physics. She lifted her left wrist to check her
watch
. The moonlight caught the small crescent-shaped scar there, a pale ridge from a childhood fall that
throbbed
whenever the air pressure dropped. The
watch
face was blank. The digital numbers
were gone
, erased as if the battery had died instantly. She tapped the glass. Nothing. She looked up at the sky. The stars were wrong. They were in the wrong positions for November. Or maybe she had been standing here longer than she thought. The codex of her memory told her she had entered the Grove at eleven o'clock. Her body felt as though she had been walking for days. A snap
echo
ed from the tree line. Rory froze. She turned
slowly
, her bright blue eyes scanning the perimeter of oaks. The trees stood like
sentinels
, their branches interlocked to form a ceiling that blocked out the London skyline. There were no cars, no distant sirens, no hum of the city. Just the flowers and the stones and the dark. Who is there? she called out. Her voice sounded flat, absorbed by the mossy ground. It did not
echo
. Nothing answered. But the flowers nearest to her right shifted. There was no wind. The air was stagnant, heavy with the scent of jasmine and rot. The poppies turned their heads. She blinked, certain it was a trick of the light. Plants did not track movement. Not on Earth. But the Grove was a pocket between realms, a place where the rules bent until they broke. The pendant grew hotter. The warmth seeped into her skin, bordering on painful. She gripped the crimson stone, intending to hide it beneath her jacket, but the glow intensified. A faint inner light spilled from the gem, illuminating her fingers and the black fabric of her sleeves. It
was drawing
attention to her. She needed to leave. The cool-headed calculation in her brain shifted from investigation to survival. She turned back toward the gap in the stones where she had entered. It looked further away now. The distance between her and the exit had stretched, the clearing expanding like a lung inhaling. She walked briskly toward the opening, counting her steps. Ten. Twenty. Thirty. The stones did not get closer. Behind her, the rustling started again. Closer this time. It sounded like dry leaves skittering over pavement, but there was no pavement here. It sounded like something dragging itself through the grass. She did not turn around. Turning around gave it permission. Turning around acknowledged the hunt. Rory stopped walking. She stood still in the center of the clearing, her hands clenched at her sides. If the time moved differently here, an hour inside could be minutes outside. Or days. If she stayed too long, she might walk out into a world where everyone she knew had aged without her. Or she might never walk out at all. The dragging sound stopped. Silence rushed back in, heavy and suffocating. She could feel the pressure of it against her eardrums. She was not alone. The certainty settled in her gut, cold and hard. Something
was standing
just behind her left shoulder. She could feel the displacement of air, the drop in temperature around her neck. She remembered the stories Silas told at the bar, half-drunk whispers about things that lived in the gaps of the city. Things that wore human shapes until they didn't. She had always laughed them off. She dealt in facts. In law. In delivery routes and tips and rent. But the warmth on her chest was real. The blank
watch
was real. The flowers
watch
ing her were real. Do not run, she told herself. Running triggers the chase instinct. She
slowly
raised her hand to the pendant. The silver chain was hot enough to burn. The crimson stone pulsed once, violently, then went cold. The sudden loss of heat was more terrifying than the burn. The light died. The clearing plunged into absolute darkness, save for the moonlight filtering through the branches. In that sudden dark, something breathed. It was not human. It was wet and ragged, coming from everywhere at once. Rory took a step back. Her heel caught on a root she hadn't seen. She stumbled, catching herself on the rough bark of one of the standing stones. The oak felt soft under her palm, like skin instead of wood. She snatched her hand away, wiping her palm on her jeans. The flowers
began to
close. One by one, the vibrant poppies and bluebells folded in on themselves, shrinking into the earth. The color drained from the world, leaving only shades of grey and black. The Grove
was shutting
down. Or it
was digesting
. She looked toward the exit again. The gap between the stones was visible now, but it
was filled
with a fog that hadn't been there before. A thick, white mist that curled around the bases of the oaks. There was no way to tell how deep it was. Rory tightened her jaw. She would not wait for the fog to reach her. She pulled the collar of her jacket up around her neck, shielding the pendant. She fixed her eyes on the gap in the stones. She would walk. She would not run. She would not look back. She took the first step. The grass beneath her boots felt spongy, like wet wool. The mist swirled, reacting to her movement. As she moved forward, the shadows of the stones lengthened again, crossing her path like bars of a cage. She stepped over the first shadow. Then the second. A whisper brushed against her ear. It sounded like her name, but distorted, stretched out like taffy. Roooorrrry. She did not flinch. She kept walking. The air grew colder with every step, biting at her exposed cheeks. The scar on her wrist
began to
itch fiercely. She focused on the gap in the stones. It was ten feet away. Then five. The dragging sound resumed, right behind her heels. It matched her pace. If she slowed, it slowed. If she sped up, it sped up. It
was tethered
to her. The pendant had led her here, and now it was done glowing. It had delivered her to the threshold, and something
was waiting
to collect the package. Rory reached the boundary. She could feel the change in the air pressure, the shift from the thick ozone of the Fae realm to the damp chill of normal London night. She stepped through the gap between the ancient oaks. The sound of traffic hit her instantly. A distant bus engine. The hum of the city. The mist did not follow her out. It stopped at the tree line, swirling angrily within the boundary of the stones. She stood on the other side, her chest heaving. She looked down at the pendant. It was dark, dormant, just a piece of jewelry again. She looked back into the Grove. The wildflowers
were gone
. The grass was dead and brown. The standing stones looked like nothing more than weathered wood. But on the ground, just inside the boundary, were footprints. They were not hers. They were bare, too large, and pressed deep into the earth, facing outward. Waiting. Rory turned away from the park and
began to
walk toward the main road. She did not look back again. She kept her hand over the stone, feeling the cold silver against her palm, knowing that the warmth would return. It always did. And next time, she would not be the one walking into the dark.
