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 heavy wool of her coat felt suddenly too thin, the damp London air clinging to Aurora’s skin like wet parchment as she ducked beneath the low-hanging boughs. Richmond Park after midnight was a different country, stripped of dog-walkers and cyclists, reduced to rolling swells of ink-black grass and the skeletal silhouettes of ancient oaks. She paused, catching her breath. Her fingers, tucked deep in her pockets, brushed against the silver chain resting near her collarbone. The Heartstone Pendant was warm—not just the lingering heat of her body, but a steady, thrumming pulse against her sternum. It was the only reason she was here, stepping past the invisible threshold into the Fae Grove, chasing a rumor that felt increasingly like a trap. Ahead, the clearing opened like an unhealed wound in the forest canopy. Aurora stopped. The hair on her arms prickled, standing straight up in the stillness. Something was fundamentally wrong with the space. It wasn't just the silence—though the absolute absence of nocturnal birds or scurrying foxes was heavy enough to press against her eardrums. It was the air itself, thick and sweet with the smell of crushed clover and copper, completely out of season for November. She took a slow breath through her nose, her cool-headed pragmatism warring with a primal, tightening knot in her gut. She had come here looking for answers about the strange burns scorching the city's perimeter, but standing at the edge of the ancient oak standing stones, she felt less like an investigator and more like a mouse that had wandered into a silo. The stones loomed pale against the dark grass, monoliths of gnarled wood and bark that had somehow turned to stone centuries ago. They formed a rough circle, a dozen paces across. In the center, the grass was disturbingly flat, pressed down in a wide, circular depression as if something massive had recently rested there. Aurora checked her watch. The luminous hands read 12:14. She had left the edge of the park barely ten minutes ago. Yet, looking up through the skeletal branches, the stars hadn't shifted an inch. They burned down with unnatural clarity, fixed in the velvet sky like pins stuck in a map. Time moves differently here, she remembered. The old warning from the urban legends echoed in her mind, stripped of its whimsical charm now that she was standing in the dark. Minutes outside could be hours in this pocket. Or days. A sound cut through the heavy air. It was a wet, rhythmic sliding noise, coming from just beyond the westernmost standing stone. *Schlock. Schlock. Schlock.* Aurora froze, her hand sliding out of her pocket to hover near the small crescent-shaped scar on her left wrist—a nervous habit from childhood she hadn't indulged in years. She didn't breathe. She strained her ears, tracking the movement. Whatever was making the sound wasn't walking. It was dragging itself, heavy and unhurried, looping through the perimeter of the oaks. At the edge of her vision, a shadow detached itself from a tree trunk. It was long, impossibly tall, and entirely disproportionate. It didn't cast a shadow of its own; rather, it seemed to swallow the moonlight around it, a silhouette of absolute absence gliding along the periphery of the clearing. It moved with a jerky, disjointed fluidity, like a marionette whose strings were being yanked by an amateur. Aurora’s heart hammered against her ribs, a violent, bird-like flutter. She told herself to turn around. Just walk back the way she came, retrace her steps to the perimeter fence, and catch the night bus back to the flat above Silas’ bar. Her fingers twitched toward the path behind her. Then the pendant against her chest flared. It wasn't just warm now; it was hot, searing against her skin like a coin left on a radiator. The deep crimson gemstone cast a faint, bleeding light through the fabric of her wool coat. With the sudden illumination, the shadows shifted. The sliding sound stopped. The silence that rushed in to fill the void was heavier, suffocating. Aurora slowly turned her head to the left. Standing ten feet away, half-concealed behind the rough bark of an oak, was something shaped vaguely like a woman. It wore a dress woven from dead vines and withered ferns, but its limbs were twice the length of a human's, bending at unnatural angles. Where a face should have been, there was only a smooth, pale oval of skin, devoid of eyes, nose, or mouth—just a vertical seam that twitched and began to part. A smell rolled over her then, rich and sickeningly sweet—the stench of rotting autumn leaves and old, stagnant pond water. The creature’s head tilted ninety degrees to the side, a sickening *pop* of cartilage echoing in the quiet clearing. It didn't have eyes, yet Aurora felt the absolute, crushing weight of its attention locked onto her. Pinned by that unseen gaze, every instinct she possessed screamed at her to run, but her boots felt bolted to the damp earth. The seam on the creature’s face cracked wider, stretching impossibly far, and from deep within its throat came a sound. It wasn't a roar or a shriek. It was the sound of a human voice whispering her name, layered over a dozen other voices speaking in unison, perfectly overlapping, echoing from the hollows of the trees. *Rory.* The name slithered across the clearing, cold and intimate. Aurora took a half-step backward, her heel catching on an exposed root. She didn't fall, but the sudden motion broke the spell of paralysis. The creature lurched forward, its impossibly long arms unfolding from its sides, fingers ending in jagged, blackened nails scraping against the bark of the nearest standing stone. She didn't think. She turned and sprinted. The dark landscape blurred into a dizzying streak of black and gray. She tore past the ancient oaks, her breath tearing raggedly from her throat, burning her lungs with the cold air. Behind her, the wet sliding sound multiplied—not one thing, but three, four, a dozen of them slithering and dragging themselves through the grass, converging on the spot she had just abandoned. Branches whipped across her face, drawing hot lines of pain across her cheeks, but she didn't dare slow down. The whispering voices chased her through the dark, overlapping, multiplying, bouncing off the trunks of the trees until the entire grove seemed to be speaking her name. *Aurora. Laila. Carter. Rory.* She burst through the line of low-hanging boughs, crashing out of the Fae Grove and tumbling hard onto the gravel path of Richmond Park. The impact knocked the wind from her lungs. She rolled onto her back, gasping, her chest heaving as she stared up at the sky. The stars here were normal. They twinkled distantly, indifferent and cold. She checked her watch with trembling fingers. 12:15. Only a single minute had passed. Slowly, shakily, Aurora pushed herself up onto her elbows. The Fae Grove sat quiet and still behind her, half-swallowed by the night fog, looking like nothing more than an ordinary clump of old trees in a public park. But as she pressed a hand to her chest, feeling the Heartstone Pendant slowly fade from its fierce crimson glow back to a dull, sluggish warmth, she knew the distance she had crossed wasn't just measured in minutes. She was back on Earth, but something had followed her through the dark.
