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 humidity of the London night died the moment Aurora stepped between the two gnarled oaks marking the entrance to the Grove. In its place came a stillness so absolute it felt like being submerged in deep water. The air was cool, smelling of damp earth and a sweetness that bordered on rot, cloying enough to coat the back of her throat. Rory adjusted the strap of her delivery bag, the weight of a lukewarm container of Golden Empress vegetable lo mein shifting against her hip. Yu-Fei had been adamant about the delivery, despite the address being nothing more than a set of coordinates in Richmond Park that Rory had been forced to cross-reference on a topographical map. It was past eleven, and the park should have been a void of shadow and rustling deer. Instead, the Grove shimmered with a pale, directional light that seemed to come from the wildflowers themselves rather than the moon. She touched the crescent-shaped scar on her left wrist, a nervous habit that usually grounded her. Tonight, it did little to settle the buzzing beneath her skin. “Hello?” she called out. Her voice didn't echo. It simply stopped, absorbed by the dense canopy of ancient oaks that stood like silent sentinels around the clearing. She shouldn’t have come. The thought was a cold prickle at the base of her neck. After leaving Evan, Rory had promised herself she would listen to her instincts, those frantic internal warnings she had spent years silencing. But the rent for the flat above Silas’ bar was due, and the ‘customer’ had promised a tip that would cover her arrears in a single night. A pulse of heat bloomed against her chest. Rory reached beneath her collar and pulled out the Heartstone Pendant. The crimson gem, usually a dormant, dark stone, was throbbing. It wasn't a flicker like a dying candle, but a slow, rhythmic expansion of light, mimicking the pace of a resting heart. It felt heavy. It felt expectant. She took a step toward the center of the clearing, her boots crunching on grass that felt too brittle for a summer night. To her left, something shifted. It wasn’t a quick movement, but a slow, deliberate folding of shadows. She snapped her head toward the sound, her straight black hair whipping against her cheeks. There was nothing there but the standing stones, their bark-like surfaces etched with symbols that seemed to pull at the corners of her vision. “I have your food,” she said, her voice tighter now, the cool-headed logic she prided herself on beginning to fray. “I’m leaving it by the center stone. You can Venmo the tip.” She didn’t move to leave the bag. Something held her in place—a sudden, crushing awareness that the geometry of the Grove had changed behind her. When she turned to look back at the twin oaks she had entered through, they looked miles away, shimmering behind a veil of heat haze despite the chill. Movement flickered again, this time to her right. A high, thin sound, like a wet finger being rubbed along the rim of a glass, vibrated through the air. It wasn’t a bird or an animal. It was a sound that had been manufactured. Rory’s thumb traced the edge of the Heartstone. The pendant was no longer just warm; it was hot, the silver chain stinging the skin of her neck. The deep crimson glow cast long, distorted shadows of her own legs across the wildflowers. “Eva’s going to come looking for me if I’m late,” Rory lied to the silence. She needed the sound of a name, something human to tether her to the world of Cardiff, law degrees, and greasy kitchen steam. A soft *thud* landed behind her. She spun around, her heart hammering a frantic rhythm against her ribs. On the ground sat a small, perfectly carved wooden doll. It hadn't been there ten seconds ago. It was crude, headless, with limbs positioned in a grotesque mimicry of a person running. A breeze finally picked up, but it didn't stir the leaves of the oaks. Instead, it carried the scent of wet copper—blood, fresh and sharp. “Is someone there?” she demanded, the intelligence in her blue eyes sharpening into a defensive edge. She gripped the strap of her bag like a weapon. “If this is some kind of Richmond Park prank, I’m calling the police.” The high, glass-rubbing sound intensified, joined by a low, guttural chittering that seemed to come from the earth itself. Rory backed away from the doll, her eyes scanning the periphery. She saw it then—a pale, elongated hand gripping the side of a standing stone. The fingers were too long, possessing too many knuckles, the skin the color of a drowned man. It didn’t pull a body into view; it simply stayed there, the tips of the fingers drumming a slow, rhythmic beat against the ancient wood. *Tap. Tap. Tap.* The Heartstone flared bright, a violent shade of ruby that illuminated the entire clearing. For a fractional second, the light revealed things that shouldn't be possible. The shadows of the trees weren't cast by the trees themselves; they were detached, tall, spindly shapes that crouched on the branches, watching her with eyes that reflected the pendant’s glow like feral cats. Rory didn't scream. Her mind, conditioned by years of navigating Evan’s unpredictable rages, went into a cold, bifurcated state of panic and calculation. *The trees are the exit. The time is wrong. The light is the key.* She dropped the Golden Empress bag. The plastic container cracked, spilling noodles across the pristine wildflowers. The scent of soy sauce and ginger felt obscenely domestic in this place. She began to run toward the entrance, but the faster she moved, the more the Grove seemed to stretch. The two oaks retreated like a mirage. The chittering rose in volume, a discordant choir of voices that sounded like dry leaves being crushed together. Something brushed the back of her heel. Rory stumbled, falling onto one knee. The ground felt soft, like moss over a hollow space. She looked down and saw her own reflection in a patch of dark water that hadn't been there a moment ago. But the reflection wasn't her. It was a version of her with hollow black pits for eyes and a mouth sewn shut with silver wire. The reflection smiled. A cold, spindly weight settled on her shoulder. Rory froze. The air around her turned frigid enough to turn her breath into a white plume. She didn't look up. She couldn't. The smell of the copper was overpowering now, joined by the musk of an animal that had been dead for a long time. “Aurora,” a voice whispered. It didn't come from the thing on her shoulder. It came from inside her own head, sounding exactly like her mother, Jennifer, but with a hollow, metallic resonance. “You’ve been away from home for so long.” The Heatstone Pendant was vibrating so violently it felt like it might shatter. It was her only light, her only defense. She reached up, not to the thing on her shoulder, but to the pendant, clenching it in her fist. The heat seared her palm, but she welcomed the pain. It was real. It was physical. She squeezed the stone and thought of the flat in London, of the smell of Silas’ stale beer, of the way the floorboards creaked under his heavy boots. She thought of the rain in Cardiff. She focused on the crescent scar on her wrist—a mark of the real world, of a childhood before shadows learned to speak. “I’m not home,” she hissed through gritted teeth. The weight on her shoulder vanished with a sharp, indignant hiss. The chittering stopped instantly. Rory didn't wait. She lunged forward, ignoring the way the ground seemed to ripple like a carpet. She stopped looking at the trees and focused entirely on the pulsing crimson light leaking through her fingers. She ran until her lungs burned, until the sweet-rot smell transitioned back into the metallic tang of London smog and the distant, beautiful drone of a car engine on Sawyers Hill. She burst through the gap in the oaks and tumbled onto the manicured grass of the park proper. The silence here was different—natural, filled with the distant hum of the city. She stayed on her hands and knees for a long minute, her breath coming in ragged gasps. When she finally looked back, there was no Grove. There were only trees, dark and ordinary in the moonlight. She looked at her hand. Her palm was blistered in the shape of the Heartstone. Rory stood up, her legs shaking. She checked her watch. It was 11:14 PM. She had entered the Grove at 11:10 PM. Only four minutes had passed, yet the vegetable lo mein had been cold, and the blisters on her hand were already beginning to scab over as if they were days old. She reached for her phone to call Silas, but her hand stopped. Attached to the silver chain of her pendant, tangled in the links, was a single, long strand of hair. It wasn't black like hers. It was white, as thin as a spider’s silk, and it was still twitching, as if it were trying to find its way back to the dark. Rory unhooked the strand and watched it blow away into the night, but even as she walked toward the park gates, she couldn't shake the feeling that she hadn't actually left the Grove behind. She felt the weight of eyes on her back, miles away but inches close, waiting for the Heartstone to dim.
