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 gate at Richmond Park had been locked since dusk, so Rory went over the wall where the ivy grew thickest, the way Eva had shown her, and dropped into wet bracken on the other side with her heart going hard enough to feel in her teeth. She waited there a moment, crouched, listening. Nothing. Somewhere far off on the A308 a lorry changed gear, and the sound came to her thin and flattened, like something heard through a wall of water. That was the first thing she noticed and dismissed. Fog, she thought. Fog does that. There was no fog. She stood, brushed her palms on her jeans, and started walking. Her phone said 11:47 and had one bar. The torch beam swung over grass rimed with something that wasn't quite frost, and the pendant lay cool and inert against her sternum, which was good — cool meant no portal, no Hel, no reason to run. She'd checked it three times on the bus from Hammersmith. She checked it again now, two fingers pressed to the crimson stone through her shirt. Cool. Fine. Everything was fine. Isolde had said midnight and had said *come alone* in the particular way the Fae said things, where the words had corners you could cut yourself on. Rory had spent the tube ride constructing arguments the way her father would have — objection, precedent, cross-examination — and by Barnes she had convinced herself that the risk was acceptable and the reward was information she could not get anywhere else. Eva had told her not to come. Silas had said nothing at all, which was worse, and had poured her a whisky she hadn't drunk. Nine hundred metres, maybe. The standing stones sat in a dip beyond the Pen Ponds, eight ancient oaks that had died so long ago they'd gone hard and grey as granite, arranged in a ring nobody in the Park's four hundred years of records had ever thought to remark upon. That was how you knew. The things that mattered were the things nobody mentioned. The deer should have been there. She thought it without wanting to, halfway across the open grass. Six hundred red and fallow deer in this park and she had never once come here without seeing them — humped shapes in the dark, the shine of eyes, that wet snorting sound they made when they didn't like you. Tonight the grass rolled away empty in every direction under a moon three days off full. No deer. No birds. Not even the pinprick chirr of a cricket. *They know something you don't,* said a voice in her that sounded suspiciously like her mother. Rory kept walking, because turning back with nothing would mean coming again tomorrow, and she was so tired of being afraid on a schedule. The stones came up out of the dark the way they always did, all at once, closer than they should have been. Eight grey teeth in a ring, the tallest of them maybe her own height, the ground between them furred with wildflowers that had no business flowering in February — foxglove, meadowsweet, cornflowers so blue they looked lit from beneath. Warmth breathed out of the ring against her face. That was normal. That was the grove doing what the grove did, holding a summer that had ended some century ago. She stopped just outside the boundary and let the torch play over the flowers. Every single one of them was facing her. Not the moon. Not the east. Every bloom in that clearing had turned its face towards the gap between the two southern stones where she stood, and they held it, unmoving, on a night with no wind. "Right," Rory said out loud. Her voice came out ordinary, and she was fiercely, absurdly grateful for it. "That's new." She stepped through. Sound changed. Inside the ring, the world acquired an echo — her footfall came back to her a half-beat late, as though the clearing were much larger than it looked, or had a ceiling. She could no longer hear the A308. She could hear her own blood. "Isolde." The name went out and did not travel. "I'm here. It's Aurora Carter. You said midnight." The flowers watched. She waited. She had learned to wait; you did not hurry the Fae, and you did not fill their silences with your own nervous chatter, because chatter was where you accidentally made promises. So she stood in the middle of the ring with her arms folded and counted her own breaths, and at forty-three she heard the humming. It was very soft, and it came from behind her. A woman's voice, or a child's — high, tuneless, three notes going round and round like water in a drain. The kind of sound you make when you're not thinking about it, when your hands are busy with something and your mind is somewhere else entirely. Rory did not turn around. She had read enough, and she had learned enough the hard way from Evan, that other kind of monster, to know that turning around was how you gave a thing permission. She stood absolutely still and let her eyes go wide and unfocused, using the edges, where movement lives. At the rim of her vision, between two stones, something adjusted its position. Just slightly. The way a person shifts their weight when they've been standing a long time. The humming stopped. The silence afterwards had a shape to it — a held-breath shape, an *I know you heard that* shape. Rory's mouth had gone dry as paper. Her hand crept up to the pendant, and she nearly laughed, because it was still cool. Cool as a coin. Whatever was in the grove with her had not come from Hel. It had come from somewhere the Heartstone had no opinion about at all, and that was somehow so much worse. "Isolde," she said, "if that's you, I'd rather you just said." The humming began again. Closer. Behind her right shoulder now, near enough that she should have felt breath, and felt none. Something moved past the corner of her eye. She caught it properly this time — a long pale shape, upright, gone behind the tallest stone with a smoothness that had nothing to do with legs. The wildflowers in its wake lay flat, then stood back up, one by one, in a slow ripple, like fingers lifting off piano keys. Rory turned her head. Fractionally. An inch. Every flower in the ring turned with her. That was when she understood, with a cold clarity that arrived all at once and settled in her stomach like swallowed ice, that the grove was not empty and had not been empty when she came in, and that whatever had been humming had been humming for a while before she noticed — perhaps since she'd climbed the wall, perhaps since she'd got on the bus at Hammersmith with the pendant cool against her skin and her arguments all neatly ordered. Behind her, in the dark, something drew a breath to speak. And Isolde's voice — the real one, the one Rory knew, unhurried and honeyed and edged like broken glass — came from very far away, outside the stones, calling her name in a tone she had never heard the Fae woman use before. Warning. *Aurora. Don't answer it.* The thing behind her said, quite pleasantly, in her mother's voice: "Rory, love. You're out awfully late."
