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 standing stones rose from the earth like broken teeth. Rory had expected them, of course. Eva's notes had been precise: ancient oak markers at the boundary, a clearing beyond, the grove itself. What Eva's notes hadn't captured was the way the stones made her feel — a deep, primal unease that coiled in her stomach and refused to unclench. She paused at the edge of Richmond Park, the Heartstone Pendant warm against her collarbone, its faint pulse quickening as she approached the tree line. The tube ride had taken forty minutes. The walk through darkened paths another twenty. She had passed joggers early on, dog walkers with their leashed animals, the ordinary traffic of a London evening. But the deeper she pushed into the park, the thinner the world became. The distant grind of traffic faded. The sodium glow of streetlamps gave way to starlight. By the time she reached the stones, she was alone in a way that felt deliberate, as if the city had quietly excused itself. She checked her phone. 11:47 PM. The screen seemed too bright, its blue-white light an intrusion. She pocketed it quickly and adjusted the strap of her courier bag. Inside: Eva's journal, a torch she hadn't needed yet, a bottle of water, and a folding knife she'd taken from the kitchen drawer of her flat above Silas' bar. The knife was not for protection, she told herself. It was just sensible. The Heartstone pulsed again, warmer now, its deep crimson glow bleeding faintly through the fabric of her shirt. Eva had written that the pendant responded to portals — to places where the boundary between worlds grew thin. The grove was supposed to be one of those places. The reason Rory had come. Eva had been missing for nine days. Rory stepped between two of the standing stones. The air changed. It happened instantly, a shift in pressure against her eardrums, like stepping off a plane into a different climate. The temperature held, but the quality of the air was different — thicker, sweeter, carrying a scent she couldn't name. Not floral, exactly. Not decay. Something between the two, as if the air itself couldn't decide what it wanted to be. The clearing opened before her. Wildflowers carpeted the ground in colours that had no business existing under starlight: violet, amber, a deep arterial red. They should have been grey or black at this hour, muted by darkness, but they glowed with their own faint luminescence, as if each petal held a trapped ember. The trees ringing the clearing were oaks, massive and ancient, their bark twisted into shapes that her mind tried and failed to resolve into faces. Rory's breath came out slow and visible, a pale cloud that lingered too long before dispersing. She took a second step. A third. The grass beneath her feet gave softly, wet with something that was probably dew. She didn't look down to check. The pendant's pulse had steadied into a rhythm that matched her own heartbeat, or perhaps her heartbeat had adjusted to match it. The distinction felt less important than it should have. She opened Eva's journal. The pages were dense with her friend's cramped handwriting, marginalia in three different ink colours, sketches of standing stones and wildflower patterns and a symbol that recurred like a motif — a circle bisected by a wavy line. Eva had been researching the grove for months before she disappeared. Her last entry read simply: *It knows I'm coming. It's waiting.* Rory closed the journal. Her hands were steady. She was good under pressure; always had been. Evan had tested that particular skill thoroughly enough. She moved deeper into the clearing, her eyes adjusting to the strange light, and that was when she heard the first sound. Not a sound, really. The absence of one. The rustling of leaves she hadn't noticed until it stopped. The night held its breath around her, and in that held breath, she became aware of something else — a low, almost subsonic hum that vibrated in her molars and the joints of her jaw. Not painful. Just present. The kind of sound you felt in your skeleton before you heard it with your ears. She turned slowly, scanning the tree line. Nothing moved. The wildflowers remained still, though there was no wind to still them. The stars overhead were wrong, she realized. Not wrong in a way she could articulate — the constellations were there, familiar patterns in their expected positions, but they seemed closer, brighter, as if the sky had lowered itself toward the earth and was pressing down. The hum shifted pitch. Higher. More insistent. Rory's hand went to the pendant. It was hot now, almost uncomfortably so, and the pulse had quickened to something rapid and urgent. She pulled it free of her shirt and the crimson glow was brighter than it should have been, brighter than it had ever been in her flat, casting her hand in shades of arterial red. She was not alone. The knowledge arrived without evidence, without sound or movement to justify it. It was simply there, complete and certain, the way the knowledge of gravity was certain. Something in the grove was aware of her. Something was watching. She turned again, slower this time, and the wildflowers had changed position. Not dramatically — a shift of inches, perhaps, the carpet of glowing petals rearranged so that the pattern they formed was different. She was sure of it. She hadn't been looking when it happened, but the flowers had moved. Or something had moved them. The hum climbed higher still, and now she could hear something beneath it — a wet, rhythmic sound, like breathing, but not. Not the breathing of anything with lungs she understood. It came from everywhere and nowhere, from the trees and the stones and the space between the stars that had pressed too close. Rory reached into her bag and took out the torch. She clicked it on and the beam cut through the grove's luminescence like a blade, stark and white and ordinary. The wildflowers it touched went dull, their inner light extinguished, and for a moment she saw the clearing as it truly was: brown grass, dead leaves, soil that looked more like ash than earth. The image lasted half a second before the wildflowers' glow surged back, reasserting itself, and the torch beam seemed to dim in response, its light swallowed by the grove's own illumination. She clicked the torch off. Her pulse was rapid but controlled. Her mind was doing what it always did under threat — cataloguing options, calculating exits, running scenarios. The stones were behind her. If she walked back the way she came, she would be in Richmond Park, in London, in the world she understood. She could leave. She could come back with help, with people, with daylight. But Eva had come here alone too. And Eva had not come back. The breathing sound grew louder. Closer. The trees at the far edge of the clearing shifted — not in the wind, because there was no wind, but as if they were leaning inward, closing the circle, narrowing the space. Rory watched one of the ancient oaks adjust its position by what might have been inches or might have been feet, the bark-face twisted now in a way that was unmistakable. Its mouth was open. Its eyes, if they were eyes, were closed. The pendant burned against her palm. She looked down at it and saw that the crimson glow had developed a pulse within its pulse — a secondary rhythm, faster, more erratic, like a heart beating too hard. The silver chain was warm. The stone itself was almost too hot to hold. Something moved at the edge of her vision. To the left, near the tree line. She snapped her head toward it and saw nothing — but the wildflowers in that spot had flattened, pressed to the ground as if something heavy had stepped there. As she watched, the flattening moved, a path of crushed flowers tracking across the clearing toward her, slow and purposeful, though nothing visible walked there. The path stopped six feet from where she stood. Rory's breath came out in a long, controlled stream. The crescent scar on her left wrist ached, a phantom sensation from a childhood she rarely thought about. She had climbed a fence in Cardiff, fallen wrong, and the metal had caught her. She remembered her father's hands, steady and calm, pressing a cloth to the wound. *Steady, Rory. Steady. We'll sort it.* She thought of Eva. She thought of the journal in her bag and the words *It's waiting.* She thought of Evan, and the way danger sometimes wore the face of something familiar. The invisible thing that had stopped six feet from her began to breathe louder. She could feel the air moving — displaced, pushed toward her in slow exhalations that carried the scent of the grove intensified, that not-floral, not-decay smell turned up to a concentration that made her eyes water. The air was warm. It was close. Rory did not run. She stood in the clearing of the Fae Grove at 11:53 PM on a Tuesday night in London, holding a burning pendant, watched by something she could not see, and she did not run. Her heart hammered and her hands shook and every instinct she possessed screamed at her to flee, but she held her ground because Eva had held her ground once too, and because the thing breathing in front of her was not trying to kill her. Not yet. It was curious. It was testing. It was waiting to see what she would do. So she did the thing that no one expected. The thing that Evan had never understood about her. She sat down. She crossed her legs on the ash-dark soil, placed the pendant in her lap, and closed her eyes. The breathing sound faltered. The hum shifted. The grove itself seemed to pause, recalibrate, uncertain. When Rory opened her eyes again, the stars had moved. The wildflowers had rearranged themselves around her in a perfect circle. And at the edge of the clearing, half-hidden by the ancient oaks, a figure stood watching — human-shaped, wrong-proportioned, its face a smooth expanse of pale skin where features should have been. It raised one long-fingered hand in what might have been greeting. Or what might have been something else entirely.
