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 oaks stood where the map said the path ended, though the map had not mentioned them by name. Rory stopped at the edge of the grass and listened. Richmond Park at this hour should have been wind in the canopy, the distant hiss of the road, a fox somewhere in the bracken. What she heard instead was nothing. The air had gone flat, as if the trees had swallowed the sound before it could reach her. She touched the pendant through her coat. The silver was warm against her sternum, warmer than her skin, and the little crimson stone gave off a pulse she felt more than saw. That was why she had come. It had started in the flat above the bar, a heat that would not settle, and it had pulled her south through empty streets until the park gates, and then here, where the grass gave way to a ring of stones that were not stones at all but the trunks of oaks grown thick and close, their bark split with age. Between them the clearing opened, and the wildflowers were already in bloom. Cowslip, campion, something pale she did not know. November, and they stood as if it were June. She stepped between two trunks. The scar on her left wrist caught on a ridge of bark and she hissed, more from the surprise of it than the pain. On the other side the quiet deepened. Her own breath sounded loud. The pendant's warmth climbed another degree. "All right," she said, and her voice came back thinner than she had sent it. "I'm here." No one answered. She had not expected anyone to. The note under her door had been three lines and no signature, and she had nearly thrown it away. Come to the grove when the stone wakes. Come alone. She had told herself she was only walking it off, that she would turn around at the first sign of anything stupid. She was still telling herself that when she noticed the flowers did not move. There was no wind. That was the thing. The branches overhead were still, every leaf held in place, and yet she could hear, very faintly, the sound of something brushing through grass. It came from the left, then stopped. She turned her head. Nothing but moonlight on petals, and the dark between the oaks. She walked toward the center because standing still felt worse. The clearing was smaller than it had looked from the path, or she was taking longer to cross it. Her boots left prints in a damp that had no source. When she glanced back, the gap she had come through was still there, two trunks and a slice of ordinary night beyond them. She could leave. The thought sat in her mouth like a coin she was not ready to spend. A twig snapped behind her right shoulder. Rory did not spin. She had learned, in other rooms and other years, that spinning gave whatever was watching the satisfaction of seeing you afraid. She kept her pace and let her eyes travel the edge of the ring. The sound did not repeat. After a moment she decided it had been a branch settling, the way old wood did when the temperature dropped. Then she heard it again, closer, and this time it was not a snap. It was the soft give of a foot placed carefully, the way you placed a foot when you did not want the person ahead of you to know you were there. Her hand went to the pendant. The stone was hot now, a small coal under the cotton of her shirt, and when she drew it out the crimson light was no longer faint. It painted the underside of her chin and the crescent scar and the silver links, and it threw her shadow long across the flowers. The shadow did not match her. It lagged by half a step, and its head was turned, as if it were looking at something she could not see. She stopped. The shadow stopped a moment later. "That's enough," she said. Her voice held. She was pleased about that, in a distant way. "If you wanted me here, I'm here. Say what you came to say." The footfalls circled. She could track them by the way the flowers bent and did not spring back. A path was being made around her, slow, unhurried, the width of a person who was in no rush because the person in the middle had nowhere to go. She turned with it, keeping the sound in front of her, and each time she turned the gap in the oaks had shifted. Not closed. Shifted. It sat now to her left, then behind her, then off at an angle that did not correspond to any direction she had walked. The road-sound did not return. The moon had not moved. Something pale passed at the limit of her vision, between two trunks, and was gone before she could fix it. Not a shape so much as an absence of dark, a vertical pallor the height of a person, or taller. She did not chase it with her eyes. Chasing it would mean admitting she had seen it, and admitting it would make it real in a way she was not prepared to manage yet. She counted her breaths instead. Four in. Four out. The pendant pulsed against her fingers in a rhythm that was not her pulse. The circling stopped. In the quiet that followed she heard breathing that was not hers. It was wet at the edges, as if the mouth making it were unused to the work, and it came from just outside the circle of crimson light. She lifted the pendant higher. The glow reached a little farther and found nothing but flowers and the scuffed track of whatever had been walking. The breathing continued. She could smell it now, a green smell, crushed stems and standing water, and under that something sweeter, like fruit left too long in a bowl. "I can hear you," she said. The breathing hitched, almost a laugh, and then a voice answered from the dark between the oaks. It used her name the way a person used a key, trying it in a lock. "Aurora." Not Rory. Not the name anyone who knew her would have chosen. The voice was low and even and almost kind, and it came from behind her, though she had been facing the sound. She turned. The gap in the trees was gone. In its place stood another oak, identical to the others, its bark split in the same places, and between its roots the flowers grew right up to the wood as if no one had ever passed there. The prints of her own boots ended in the grass three paces back and did not continue. She was not sure when she had lost the way out. That frightened her more than the voice. "You sent the note," she said. "I sent nothing." The voice had moved again. Left of her now, low to the ground, as if the speaker had crouched. "The stone sent you. It does that, when a door is thinking of opening. It gets warm. It wants to be near." The pendant jerked in her hand, a single hard tug toward the center of the clearing, and the heat flared until she nearly dropped it. She closed her fist around the chain instead. The links bit her palm. On her wrist the old scar itched, a thin bright line of sensation that had nothing to do with the bark. "There's no door," she said. "Not yet." Something moved at the edge of the light. This time she looked. A hand, or the idea of a hand, rested on the grass among the campion. The fingers were too long and the color of the underside of a leaf, and they did not cast a shadow even where the crimson fell across them. They curled once, slowly, the way a sleeper's hand curled, and then they withdrew into the dark with a sound like cloth dragged through wet leaves. The breathing had stopped. In its place she heard, very small, the tick of the pendant's chain against her knuckles, and under that a second rhythm, slower, coming up through the soles of her boots. The ground was keeping time. She took a step back and her heel found the track the circling thing had made. The flowers there were blackened, not crushed. They had been burned down to their stems in a perfect curve, and the curve was closing. Where she stood was the last gap in it. Beyond the blackened line the clearing looked the same, moonlight and bloom and the patient oaks, but the air on that side of the line had a different weight. She could see it the way she could see heat above a road. It bent the trunks. It made the moon, caught between two branches, ripple as if it were under water. "If I step over," she said, "what happens." "You find out why the stone is warm." The voice was in front of her again, and closer, though she still could not see a mouth to put it in. "Or you stay on that side and walk until morning, and morning does not come, and the flowers keep blooming, and you keep being almost alone. Those are the choices the grove offers. It is more generous than most places." A shape detached itself from the nearest oak. It had been there the whole time, she understood, pressed flat to the bark, the same color, the same splits, and only now had it decided to be separate. It was tall. It had shoulders. Its face was turned away, and where a face should have caught the light there was only the smooth grain of wood, knotted, unmoving. It did not step toward her. It did not need to. The blackened curve in the grass crept forward another inch, and the last of the unburned flowers at her feet began, very gently, to smoke. Rory held the pendant up between them. The crimson glow struck the wooden face and found no eyes to reflect in, and the thing's head tilted, curious, the way a bird's did. From somewhere beyond the ring, impossibly far and also just at her shoulder, she heard the road again for a single second, a car passing, ordinary and gone. The sound made her throat tighten. She thought of the flat, the bar below it, the stair that smelled of beer and rain. She thought of the gap that was no longer there. The thing took one step. The ground answered. And the pendant, hot enough now to hurt, pulled toward the center of the circle as if the door it had been warning her about had finally, patiently, begun to open.
