You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

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. </instructions>

The perimeter of Richmond Park dissolved into gray mist behind the ancient oak boundary stones. Rory stepped over the roots, the soles of her scuffed boots sinking into damp loam. Here, inside the pocket, summer lingered out of season. Bluebells and pale anemones choked the forest floor under a sky stripped of stars. The air smelled of crushed mint and wet iron. She tapped the screen of her phone. Zero bars. The voice memo app recorded silence, the red timer ticking upward second by second. "Eva, if this audio uploads later, the drop wasn't at the bridge." Rory held the microphone close to her chapped lips. "The note under the shop door directed me past the stones. Ten past midnight." The digital counter on the screen flickered, skipped from twelve seconds to forty-eight, then froze completely. Rory pinched the bridge of her nose, her thumb brushing the small crescent scar on her left wrist. A dull ache throbbed along the old tissue, phantom nerve pain flaring whenever the weather turned sour. Except the weather had not turned. The air clung to her neck, stagnant and warm, devoid of any breeze. Leaves hung motionless from the canopy. In the park proper, a mile to the west, red deer brayed this time of year and the distant murmur of night traffic hummed from the A3. Here, absolute quiet settled like fine silt over the glade. Rory reached under her collar. Her fingers closed around the Heartstone pendant. The thumbnail-sized crimson jewel sat heavy against her sternum on its delicate silver chain. Usually cool as river gravel, the stone radiated a stubborn, rising heat. The dull red glimmer beneath its faceted face pulsed in sync with her own pulse, then hitched, beating twice in rapid succession. She let go of the pendant. It burned a small circle of skin through her cotton shirt. "Silas? Yu-Fei?" Her voice struck the clearing and died instantly, swallowed without an echo. The oaks absorbed the syllables like damp wool. Rory swept the white beam of her pocket flashlight across the trunks. Rough bark, emerald moss, the knotty burls of trees hundreds of years old. Nothing shifted. Yet the hairs on the back of her arms rose. A pressure formed behind her ears, the sensation of diving too fast into deep water. She took three paces toward the center of the ring, where the wildflowers grew thickest. *Crunch.* She froze. The sound had come from behind her left shoulder, precise and dry. A twig snapping. Rory pivoted on her heel, swinging the light low. Pale stalks stood upright. Fallen twigs lay untouched in the green tangle. "Show yourself." She kept her tone flat, level, Cardiff bluntness cutting through the humid dark. "I have the parcel from the restaurant. If this is a joke, I am dumping the food on the moss and walking back to the flat." Silence answered. She lowered the beam. At the outer periphery of the illumination, past the reach of the white circle, darkness gathered in unnatural density. It pooled between the massive trunks like thick engine oil, resisting the spill of light. Rory took a backward step, her eyes trained on the black gaps between the timber. Another sound followed. Not behind her this time, but directly overhead in the interlocking branches. A slow, wet drag, reminiscent of raw meat sliding across smooth bark. She tipped the light up. The leaves remained rigid, lacquered green. No owl roosted on the lower boughs. No squirrel shifted in the canopy. But three feet above her head, an oak branch dipped under sudden, concentrated mass. The wood groaned under the weight. The bark dimpled inward, yet the flashlight revealed only empty air pressing the limb toward the earth. Rory backed away, her breath shallow. "Right." She turned toward the gap in the boundary stones. "Delivery canceled." She marched toward the perimeter. Her steps were deliberate, measured to avoid tripping on the snarl of roots. Five strides. Ten strides. The boundary stones had not appeared. The clearing stretched out before her, wider now than when she had crossed the threshold. The ancient oaks, once arranged in an irregular oval fifty yards across, receded into an endless colonnade of identical, twisting trunks. The path she had cut through the waist-high wildflowers showed no broken stems, no crushed leaves. The earth behind her was pristine. The Heartstone surged with sudden, blistering heat. Rory gasped, tearing at her collar, hooking two fingers under the silver chain to pull the crimson gem off her chest. Through her knuckles, the stone kicked like a trapped hornet. A click sounded near her right ear. It was sharp, the clacking of teeth snapping together. Rory spun, swinging her fist blindly. Her knuckles struck nothing. The disturbance displaced the air, wafting a cold stench over her face: spoiled milk, copper, and subterranean damp. "Who is there?" She demanded, the words rattling in her throat. A voice answered from the undergrowth, scarcely three feet away. It matched her own timbre, her own flat Welsh cadence, mimicry scraped raw at the edges. "Delivery canceled." The skin on Rory's scalp contracted. The sound had come from a patch of purple nightshade near a hollow stump. The flowers swayed, vibrating in place while the rest of the grove remained utterly dead. She kept the flashlight trained on the nightshade. "Evan?" The name slipped out before reason could choke it down. The past had a habit of stalking her, but Evan was six foot two and heavy-footed, unable to move through bracken without snapping branches like matchsticks. The nightshade parted. No creature emerged. Instead, two parallel depressions sank into the black dirt, side by side, six inches long. The mud squelched as weight settled into the tracks. Two more depressions sank behind them. Something long and low to the earth crouched just beyond the edge of the visible spectrum, its mass displacing physical space without reflecting light. The Heartstone burned so hot Rory dropped it. It swung against her ribs, searing her skin through the fabric. The faint inner crimson glow flared to a violent, bloody glare, casting red reflections across the backs of the oak trees. In the crimson sheen, shadows bent backward. The trunks cast shadows toward the light source instead of away from it. Black fingers of darkness crept across the clover, reaching for Rory's boots. She retreated, her heels catching on an exposed root. She stumbled, caught her balance with a hand against an ancient trunk, and pulled her palm back instantly. The bark was warm, slick, and shuddering with a steady, sluggish heartbeat. "Not a tree," she muttered under her breath, wiping her sticky hand against her jeans. The darkness between the trunks rippled. The colonnade shifted, rearranging its geometry in the corner of her vision. Every time she blinked, the oak she had touched seemed to stand three feet closer to the center of the ring. A sound started in the canopy—a soft, collective rustle that wasn't wind. Millions of leaves turning their undersides upward at once, exposing pale, veined bellies to the lightless sky. "Rory," the grass whispered near her ankles. The mimicry had lost its Welsh inflection. Now it carried the cadence of Silas, deep and gravelly, warped through a broken speaker. "Rory. Drop the food." She snapped the flashlight off. Absolute blackness slammed down like an iron grate. In the pitch dark, she listened. She heard no rustling grass. She heard no scraping claws. Instead, she heard the synchronized intake of breath. Two lungs filled with air directly in front of her face, so close that the expelled vapor brushed against her eyelashes, smelling of winter and old graves. Rory did not move. She did not scream. Her fingers traced the crescent scar on her wrist, grounding herself in the pain, while the invisible thing in the dark exhaled against her forehead.
