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 the Ham Cross entrance had been chained since dusk, so Rory went over the fence, which was the sort of decision she'd stopped interrogating somewhere around her third week in London. Her palms came away rusty. Her trainers found wet grass. Behind her, the road noise thinned to a distant hush, like the sea heard through a wall, and then it thinned further, and then it was gone. That was the first wrong thing, though she didn't know it yet. Richmond Park at night was supposed to be a held breath — deer shifting in the bracken, planes stitching their lights across the sky toward Heathrow, the orange bruise of the city smeared along the horizon. She'd walked it before. She knew the shape of it. Tonight the sky above her was clean and black and starred in a way no London sky had any right to be, and there was not a single plane in it. Rory stopped on the path and looked up for a long moment, and told herself: high pressure system. Fog on the ground, clear above. Flight paths change. The pendant lay warm against her sternum, the way it always did now. Not the pulsing warmth — not the throb it had given off in the basement of the Golden Empress, that sick, arterial rhythm she'd felt through two layers of clothing. Just warm. Baseline. Alive. She'd come because Isolde had told her to come. *At the turn of the moon, when the grass is silver. Come alone, small thing, and I will tell you the name of the one who put that stone around your neck.* Which was the kind of offer Silas had spent forty minutes telling her not to take, and Eva had spent five minutes telling her not to take, and which she had, obviously, taken, because a name was a thread and she was so tired of not having anything to pull. The standing stones came up out of the mist ahead of her. They were oak, not stone, despite what everyone called them — five trunks, dead and silvered and hard as iron, set in a rough ring wider than a house, so ancient they'd gone the colour of bone. They looked like fingers. She'd thought that the first time and she thought it again now: five fingers of something enormous, buried up to the knuckle, waiting with terrible patience for the rest of itself. Rory stepped between two of them. The air changed. It always did — a pressure shift in the ears, a sweetness like cut fruit, the temperature climbing eight or nine degrees in the space of one footfall. Behind her the park would be doing its own thing at its own speed; an hour here might cost her a minute out there or a fortnight, and there was no way to know until you were back and looking at your phone with your heart in your mouth. Wildflowers to her knees. Cornflowers, foxglove, ox-eye daisies, meadowsweet — everything in bloom at once, in November, in the dark, glowing faintly the way white things do at night. The grove breathed its warm sweet breath at her. And it was empty. "Isolde?" Her voice went nowhere. No echo, no carry. It fell off her lips and landed at her feet. She waited. She counted to sixty, which she'd learned was the right thing to do here — the fae had a horror of eagerness, they liked you to be still, they liked you to be a little bored. She counted to a hundred and twenty. She looked at the moon, which was where it should be, high and thin and silver, and at the grass, which was silver, so the terms of the invitation had been met. Then, from somewhere in the flowers to her left, a phone began to ring. Rory's whole body went to glass. It was her ringtone. The stupid default one she'd never changed, the marimba thing, three notes climbing and then repeating, muffled slightly, as if the phone were in a pocket or under a coat. It was coming from about ten metres away, in the meadowsweet, at ground level. Her own phone was in her jacket. She put her hand on it through the fabric. Silent. Still. The ringing stopped mid-phrase, the way it does when someone picks up. "Hello," said a voice in the flowers. Her voice. Not an impression of it, not a near-miss — *hers*, the exact Cardiff-underneath-London vowels she'd spent seven years sanding down. Warm. Slightly amused. "No, I'm here now. It's fine. I'll ring you after." Rory did not move. Her heart was going so hard she could feel it in her gums. Silence again. Deep, sugared, floral silence. The flowers where the voice had been were not moving. *Right,* she thought, with a calm that felt borrowed from someone braver. *Right. That's a mimic, or a glamour, or a trap, and either way the answer is the same, which is that you leave.* She turned around. There were four standing stones behind her. She counted them twice, moving her lips, because she had walked between two of them ninety seconds ago and there had been five, there were always five, everyone said five, Eva had drawn her a map with five little dashes on it in biro. Four dead oaks stood in the mist with the gap where the fifth had been showing her a long empty run of grass. Something moved out there. In the gap. Not toward her and not away — across, at a walk, tall and unhurried and gone before she could resolve it into anything but the idea of a shape, the way a word you've almost read still leaves a mark on your eye. Rory's hand went to the pendant. It was cold. She'd never felt it cold. Warm at rest, hot near Hel, but never this — a hard little knot of winter against her breastbone, the silver chain gone icy enough to sting the back of her neck. She fumbled it out of her collar. The crimson gem had gone dull. Not dark, exactly: *turned*. Like an eye rolled back. "Isolde." She didn't recognise her own voice this time, and she thought, distantly, that maybe that was because the grove had it now. "Isolde, I'm invoking hospitality. I was invited. I'm invoking it." The wildflowers rustled. All of them. Every stem in the clearing, in one long soft wave that started at the far tree line and rolled toward her like something enormous drawing breath through pursed lips — and there was no wind, there had never been wind here, the air was as dead as a held cup. Rory started walking. Not running. Running was the thing you did last, running was the thing you did when you'd already lost, and some cold clean part of her brain was still functioning and it said: *walk, and do not look at the gap, and count your steps, and get out through the two stones you came in by.* She counted eleven steps. On the twelfth, somewhere behind her and quite close, at the height of a mouth beside her ear, her own voice said, kindly, "You're going the wrong way, Rory." She stopped. Every instinct she had was screaming at her to turn, and she knew — with a certainty that arrived whole and undeniable, the way the worst knowledge always does — that turning was exactly what it wanted, and that behind her there would be nothing at all, and that would be so much worse. The scar on her left wrist ached, the way it had ached in the delivery van the night the pendant first burned. "No," she said aloud, to the grove, to the flowers, to the thing wearing her mouth. "No, thank you." And then she ran.
