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 mist in Richmond Park had a bitter, wet bite that tasted of chimney smoke and dead river moss, but the moment Rory passed between the two oak standing stones, the cold vanished. She stopped on the damp turf, her boots sinking an inch into soil that had suddenly turned soft and thawing. The chill of a London November washed off her skin like bathwater, replaced by an unnerving, humid stillness. Around her, the darkness was thick enough to chew, yet the clearing was impossibly bright with color. Foxgloves, bluebells, and thick heads of wild sweet pea choked the ground, their petals fully unfurled in the middle of the night, shining with an oily, bioluminescent sheen under a sky that held neither moon nor stars. Rory reached up with her right hand, her thumb tracing the faint, crescent-shaped scar on her left wrist—an old, unconscious habit that usually anchored her when a situation began to tilt sideways. Her cool-headedness was usually her greatest asset, the sharp, logical edge that kept her grounded when everything else fell apart. But standing in the center of the Fae Grove, surrounded by flowers that had no right to be alive, her logic felt paper-thin. She had come here for answers about the artifact around her neck, following a vague lead that had seemed reasonable enough under the bright fluorescent lighting of Silas’ bar. Now, isolated in this pocket of folded space, the trip felt like a catastrophic miscalculation. The silence was the first thing that set her teeth on edge. Richmond Park was never truly quiet. Even in the dead of night, there was the low, electric thrum of the city beyond the gates—the distant, rhythmic hiss of tires on wet asphalt along A307, the low drone of late-night flights crawling down toward Heathrow. Here, there was nothing. No traffic. No wind. No night birds. The absolute, suffocating quiet sat heavily on her eardrums like air pressure in a plunging elevator. Beneath her coat, against her collarbone, a needle-point of heat bloomed. Rory unbuttoned the top two buttons of her jacket and drew out the Heartstone. The small, thumbnail-sized gem hung from its delicate silver chain, its deep crimson heart thrumming with a slow, rhythmic pulse. It wasn't just warm; it was beating like a tiny, frightened bird against her palm. A faint, blood-colored light seeped between her fingers, casting long, wavering shadows across the carpet of summer blooms. The pendant pulsed warm when a Hel portal was near. But the air around her felt empty. "Rory," she told herself, her voice flat and even in the hush, "focus." Her voice didn't carry. The dense, flowered air absorbed the sound instantly, deadening it so completely that it sounded as if she were speaking inside a box lined with velvet. She took three careful paces toward the center of the grove, where the ancient oak stones formed an uneven circle. The path behind her was already blurring; the gap between the two entrance stones seemed narrower now, squeezed together like teeth closing on a bite of air. She knew the lore—time and distance in the Grove were unstable, elastic things—but watching the geometry of the clearing slip and slide in the corners of her vision made her stomach drop. She bent down, brushing her fingers over a clump of pale white clover. The leaves were hot to the touch. Not warm—feverish. A rustle broke the stillness. It was faint, coming from the far side of the stone circle, a dry, sliding sound like heavy canvas dragged across wet gravel. Rory froze, her bright blue eyes wide as she scanned the perimeter. The crimson glow from the Heartstone carved out a narrow circle of light around her boots, but beyond that, the shadows between the massive oak sentinels were solid, ink-black walls. "Hello?" she called out, though she knew better. In a place like this, naming yourself or acknowledging the dark was an invitation. No voice answered, but the rustling stopped immediately. Too immediately. It didn't taper off the way animal movements did; it cut off sharply, as if whatever had made the sound was now listening just as hard as she was. Rory slowly stood up, letting her hand fall to her side. Her heart was hammering a steady, fast cadence against her ribs, but her brain remained cool, working through the variables. The entrance was roughly twenty yards behind her. The terrain was uneven. If she ran, she risked tripping on the thick tangle of unseasonal vines, and in the Grove, losing your footing could mean tumbling into a different hour entirely—or a different century. She took a slow step backward. The Heartstone against her skin flared. The warmth turned to a sharp, stinging heat, the silver chain biting into the back of her neck. The crimson glow brightened, spilling out further, painting the white petals of the flora in shades of fresh arterial blood. Out at the edge of the light, something moved. It wasn't a shape she could define. It was a absence of light that was darker than the night around it, a tall, narrow smudge that slid silently from behind one of the standing stones to the next. It didn't walk; it flowed, staying crouched low to the earth, hugging the tree trunks. Rory kept her eyes fixed on the spot, refusing to blink. But when she shifted her gaze slightly to keep the shadow in her central vision, it vanished. The moment she looked away, she caught the faint, fluid movement again in her periphery—closer this time. Much closer. It was using her blind spots. A subtle draft swept past her ankles. It didn't carry the sweet, suffocating scent of the Grove’s flowers. It smelled of sulfur, iron, and old, wet ash. The pendant burned hot enough now to scorch. The crimson pulse was no longer rhythmic; it was frantic, flickering like a dying strobe light. *A Hel portal isn't opening,* she realized with a cold, crystalline certainty. *It's already here. It's walking.* She took another step backward, her boot heel catching on a thick root. She caught her balance, her shoulder skimming the rough, mossy bark of one of the standing stones. Touch proved what her eyes had denied her: the stone was trembling. Deep inside the ancient heartwood, something was vibrating at a pitch too low for human ears to hear, a subterranean hum that rattled the teeth in her jaw. From the dark directly above her head, a breath went out. It was a slow, wet exhalation, warm and smelling of copper, stirring the straight, shoulder-length black hair at the crown of her head. Rory didn't look up. She knew that to look up was to acknowledge it, to bridge the gap between being stalked and being taken. Instead, keeping her gaze locked on the closing gap between the entrance stones ahead, she forced her muscles to relax, coiled herself tight, and took a deep, deliberate breath. The shadow dropped silently into the grass three feet in front of her. It had no face, only a narrow, weeping slit where a mouth should have been, and long, terrible limbs that bent at too many angles. It didn't make a sound as it rose to its full, unnatural height, blocking out the path, blocking out the light, filling her vision with an absolute, lightless void. Rory squeezed the crimson stone in her fist, feeling the heat sear her palm, and took her step.
