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.

The stones were older than the park's paths, older than the deer that drifted between the bracken, and Rory could feel their age before she saw them. Dusk had settled over Richmond like a dropped cloth. Behind them the lights of Sheen Gate blinked on one by one, then went small and distant, as if someone had turned the volume down on the world. "Don't touch the oaks," Isolde said without turning around. Her silver hair moved down her back like poured water. "They remember hands." Rory pulled hers back from the nearest trunk, where bark had split into deep grooves that looked almost like script. Her wrist ached along the thin crescent scar, the old reminder she had not thought about in months. She tucked her hand into her jacket pocket instead and felt the Heartstone through the lining. It was warm. Not hot, just the steady warmth of a palm resting on a cup of tea. She had decided hours ago not to mention that to anyone. Nyx drifted at the edge of the group, a long figure cut from the dusk itself. Where the last of the light fell, they were a tall, human outline of darkness; where it didn't, they were nothing at all, just a shadow that lay wrong on the grass. Their voice came from somewhere near her shoulder, soft as wind through a keyhole. "You're counting the steps again." "I'm not." "Eleven since the last stone. You always count when you're frightened." "I'm not frightened. I'm paying attention." She glanced down at the ground and stopped. Isolde had walked ahead, and the grass she had crossed was bent as if no one had ever stood on it. Rory's own boots pressed the blades flat, and when she lifted her foot the grass slowly, reluctantly, rose again. Nothing in the Grove, she was beginning to understand, behaved the way it ought to. "Come," Isolde called. "The gate is open. It won't stay open for long, and it does not enjoy waiting." They passed between two standing stones. Rory had expected a jolt, the sort of pressure change she associated with lifts or aeroplanes. Instead the air simply thickened, like stepping into warm honey, and the sound of traffic from the road dropped away so completely that her own heartbeat seemed loud. Then the light changed. It came not from the sky, which had gone no further toward night, but from the ground. Wildflowers covered the clearing: foxglove and bluebell, poppies and something with petals like frosted glass, all blooming at once. Their colours were too clean. Rory had grown up in Cardiff, where even the parks wore a layer of soot and rain. These flowers looked freshly painted. Bees moved among them, but the bees were slow, drifting in lazy spirals as though the air was too heavy for them. "Wildflowers all year," Isolde said, and Rory had the odd impression she was reading from a card. "Spring is always here, and the frost never comes. That is the first kindness and the first warning." "What's the second?" Rory asked. "That you will want to stay." Nyx made a sound that might have been a laugh. "She says that to everyone." "And everyone listens," Isolde replied serenely. "Sometimes they even heed it." They moved on. The path wound between trees whose trunks were pale as bone and whose leaves turned slowly, though there was no wind. Rory caught herself listening for birdsong and heard nothing, then realised the silence was not empty. It was full of something low and patient, a hum just beneath hearing that made the fillings in her teeth ache. Every so often a thread of shimmer crossed her vision, a faint distortion like heat above tarmac, gone the moment she turned toward it. She thought of the Veil, which she had only ever read about in Wardens' reports and half-remembered lectures, and wondered whether she was seeing it or whether it was seeing her. The Fae blade at her hip went cold against her thigh. She had grown used to that, the way it never warmed no matter how long she carried it, but now the chill spread through the fabric of her trousers, sharp and clarifying. Moonsilver, Isolde had called it, and she had not asked where the moon was. Ahead, the trees opened onto a pool. It was perfectly round and perfectly still, and its surface reflected not the pale trunks around it but a sky full of stars. Rory stopped at the edge. The stars in the water were moving, drifting slowly across a sky that did not match the one above. A single shooting star fell through the reflection and left a trail that hung for a long moment before fading. "Don't fall in," Nyx murmured. "Not everything that falls comes back out." "Would you come after me?" "I might. I'd have to ask first who else had gone in, and why." Rory crouched and let her fingers hover above the water without breaking the surface. The Heartstone pulsed once against her chest, a warm knock, and the reflected stars shivered. She went very still. Somewhere far beyond the trees, under all that glittering sky, there was a door, and it had noticed her. Isolde's pale lavender eyes found her across the pool. "Ah," she said softly. "You have brought something with you, child. Now we shall see whether it brought you." Rory stood, slowly, and found that she had already decided to go on. That, more than anything, frightened her.
