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 park had a different smell at night. Rory noticed it the moment she slipped through the gap in the railings — wet grass and leaf-rot, and underneath it something sweet that had no business being sweet in November. She'd delivered enough orders from the Golden Empress to the streets around Richmond to know where the fence bent, where the cameras didn't reach, where a person could be inside the park without ever touching a gate. Useful knowledge. She was trying very hard to think of it as useful, and not as the first bad decision in what might become a pattern. Nineteen nights. That's what it had taken to get her here. Nineteen times she'd woken at 3:17 in the morning with the pendant hot against her sternum, pulsing in a slow, deliberate rhythm, like something practising being a heart. And the dream — always the same dream. A clearing. A ring of ancient oaks standing like stones. Wildflowers open in the dark. Tonight she'd stopped pretending it would go away on its own. She pulled her jacket tighter and started across the grass. The city noise died behind her with a speed that felt deliberate — one step and the distant grumble of the road was there, the next it was gone, swallowed, as if the park had closed its mouth. No wind. No foxes. Richmond at night should have been full of small sounds, the rustle of things going about their business. There was nothing. Her own footsteps came back at her half a beat late, as though the dark were repeating them to itself, learning them. The deer were the first wrong thing she could point at. She found them in the long meadow where they always were, two hundred head or more, and every single one of them was standing. Not grazing. Not sleeping. Standing, motionless, all facing the same direction — toward the treeline to the south, toward the place she was going. They looked like a congregation waiting for a sermon. Rory stopped walking. As one, with a sound like a soft wave going through the grass, they turned their heads and looked at her. She counted her exits the way she always did, the way she'd taught herself to after Evan, and she walked on, wide of them, unhurried. Running was prey behaviour. She'd read that somewhere, and her whole body believed it. The humming started when the treeline came into view. It was faint enough that she first took it for blood in her ears. Then the tune resolved, and her stomach went cold. Suo Gân. Her Nain's lullaby, the old Welsh one, the one her mother used to sing in the kitchen when she thought no one was listening. Whoever was humming it knew the melody and was getting it wrong on purpose — one note flat, the same note every time, a flaw placed in it like a signature. The pendant pulsed. Rory put her hand flat over it through her shirt and felt the warmth of it, the faint crimson glow leaking between her fingers, and underneath her palm she counted. Her own heartbeat, quick and human. And the pendant's, slower, patient, answering something she couldn't hear. It was not beating with her. It had never been beating with her. The oaks stood in a ring on the rise, enormous and ancient, spaced like standing stones, and even in the dark she knew them. She'd seen them every night for nineteen nights. Between two of them was a gap the width of a door, and through the gap the air looked different — softer, faintly lit, as if the clearing beyond kept its own weather and its own moon. She should have turned around then. Every story her Nain had ever told her said so. Instead she thought about the parcel with no return address, her name written on it in handwriting that was almost, almost her own, and she stepped through. Warmth closed over her like water. The smell of the sweet thing intensified a hundredfold, and she saw why: wildflowers, hundreds of them, open everywhere across the clearing, faces pale in the dark. Blooming. In November. The grass was summer-dry underfoot. Behind her, through the gap, she could see the dead November meadow she'd just left, grey and wet, as if it were a photograph of somewhere else. Her phone, when she checked it, said 3:17. The text she'd sent Eva before crossing — grove, richmond, back by 4, call police if not — showed no signal and a spinning wheel that spun and spun. "Aurora." She didn't turn around. It was Evan's voice, soft and reasonable, the voice he'd always used in the doorway of a room, the one that meant the evening was about to go one way and there was nothing she could do to stop it. Evan was in Cardiff. Evan had never once said her name from inside an oak wood in Richmond at three in the morning. "Aurora. Look at me." She bit the inside of her cheek until she tasted blood, and she watched the wildflowers instead, and that was how she saw them move. Not swaying — there was no wind. Turning. Slowly, in ones and twos across the clearing, swivelling on their stems until their pale faces were aimed at her, all of them, a field of small attentions. The lullaby stopped. In the silence, something knocked — once, twice — from the inside of the nearest oak, a wet wooden sound, knuckles against the far side of the bark. Rory walked to the centre of the clearing because she had come for an answer and she was not going home without one, and because the pendant was pulling her there, the silver chain drawn taut against the back of her neck, the stone tugging toward a spot in the air like a compass needle that had finally found its north. At the centre of the clearing the night had a seam in it. It hung at chest height, a vertical slit of darkness no longer than her forearm, and it had depth. That was the wrongest thing about it — it was not a tear in the air, it was an opening, and on the other side of it was a darkness with distance in it, and faint points of red light that were not stars, because they were arranged like nothing in any sky, and because one of them was moving. Coming closer, the way a lantern comes closer down a long corridor. The cold that breathed out of the seam smelled of wet stone and, very faintly, of the sweet flowers. The crescent scar on her left wrist began to itch, and then to ache, cold as a held coin. "You kept it." The voice came from the seam, and it was no one's voice, no stolen thing — old, dry, unhurried, the sound of pages turning in an empty room. "Nineteen nights. I began to think you'd lost the courage of your curiosity." Rory said nothing. Her Nain's stories had rules and she could feel them standing around her now like the oaks: don't eat, don't thank, don't give your name, don't step inside the circle. Don't answer. The red light in the seam grew, and she understood, with the calm, clear terror that had always been her gift — the part of her that went quiet when other people screamed — that the light was not approaching. It was dilating. Like an eye. "A gift given is a door opened," the voice said. "It beats because it remembers being a heart. Hearts go home, Aurora Carter. They cannot help themselves." At the treeline, at the edge of her vision, something tall unfolded itself from beside an oak and stood there, patient, branch-crowned. When she looked at it directly, there was only the tree. When she looked back at the seam, it had moved to the next oak along. Closer to the gap. To the door. She took the pendant off. The chain whispered over her hair, and she held it out at arm's length, over the seam, the crimson stone swinging, glowing, nearly hot enough to burn. Every sound in the grove stopped. The tall thing at the treeline stopped. The red eye in the dark widened, and she felt its want the way you feel heat from a fire — and she understood the last rule, the one underneath all the others. It could not take. It could only be given. That was the whole architecture of this place, of the parcel, of the dreams. Nineteen nights of knocking, and the door only opened from her side. "No," she said. The one word, all she would spend. She put the chain back over her head, turned her back on the seam, and walked for the gap between the oaks. Behind her the voices began again — Evan, reasonable, wounded; her mother, calling cariad in a cadence that was almost right, almost; her own voice, young, the one she'd had before all of it — and she counted her paces the way she counted doors on a delivery round, eleven, twelve, thirteen, and did not run, and did not look back, even when the tall thing paced her along the treeline with its branching crown, even when her mother's voice said, tender and wrong, see you soon, love. November slapped her in the face on the far side of the oaks. Wind, wet grass, the far-off grumble of a lorry. Her phone buzzed: 3:17 a.m., one bar, Eva's text from half one — you okay?? Nearly three hours gone. She'd been inside perhaps forty minutes. She walked fast across the meadow. The deer were gone, all two hundred of them, as if the field had never held anything but grass. It wasn't until she was under a streetlamp on the road outside, hands shaking, that she noticed the pendant had gone cold against her chest. Cold as any stone. She stood there holding it through her shirt, and the thought arrived the way the worst thoughts always did, quietly, in her own reasonable voice. The pendant had been warm for nineteen nights. Warm in her bed, warm in the dark of her flat above the bar, miles from Richmond, miles from any ring of oaks. She'd thought the grove had been calling to it. But the stone warmed when it was near a door. It had been warm the whole time. Pulsing, in the black small hours, at 3:17 exactly. Answering something.
