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 standing stones came upon them all at once, the way a memory does — there and then suddenly undeniable. One moment Rory was pushing through the ordinary bracken of Richmond Park, the cold October damp soaking through the knees of her jeans, and the next she stood before a ring of ancient oaks that had no business existing. They were not trees, not quite. They had the shape of trees, the gnarled bark and the reaching boughs, but they had grown into the rough columns of standing stones, or perhaps the stones had softened into wood — she couldn't tell which had come first. Lichen the color of old bone clung to their flanks. Between them, the air shimmered, a faint distortion like heat rising off summer tarmac, though the day was grey and bitter. "There," Nyx said. Their voice came from somewhere just behind her left ear, a whisper that the wind seemed to carry rather than speak. In the daylight the Shade was little more than a smear of deeper dark against the gloom of the trees, a humanoid suggestion that the eye kept trying to resolve and failing. "Do you feel it?" Rory did. The Heartstone pendant lay cold against her sternum here — it only warmed near Hel — but something else pulled at her, a low hum she felt in her teeth and the soles of her feet. Like standing too close to a struck bell after the sound had faded. "Eva, stay close," she said. Eva, who had dragged her to London and then into this, nodded too quickly, her breath clouding. "I keep telling myself this is normal. A normal Tuesday. Walking into a fairy ring with a shadow person." "Wednesday," Nyx corrected. "That's not better." Rory stepped through the gap between two oaks. The world changed the way a held breath releases. The cold went first — not warming exactly, but thinning, peeling back to reveal a different air beneath it, soft and green-smelling, full of pollen and something sweeter she couldn't name. The grey sky did not so much brighten as deepen. When she looked up, the canopy of those impossible oaks knit together overhead into a lattice of branches through which light fell in slow golden shafts, though there was no sun she could find to source it. And the flowers. They covered the clearing floor in a tide — bluebells and foxgloves and things that had no English names, blossoms shaped like trumpets and bells and open palms, in violet and white and a blue so saturated it seemed to vibrate. Bluebells did not bloom in October. None of these should bloom together, spring and summer and autumn flowers all crowded into one riotous meadow. But here they did, year-round and unhurried, swaying though there was no breeze. "Oh," Eva breathed, coming through behind her. The word fell out of her like something dropped. Nyx came last, and Rory turned in time to see them change. In the grove's strange light the Shade had gained substance — no longer a smudge but a tall figure, easily six foot two, edges still feathering into shadow but the suggestion of a face now, the faint violet glow of their eyes steady as twin pilot lights. They looked down at their own hands as though surprised to find them. "I have more shape here," they said softly. "This place sits closer to the spaces between. It remembers what I was." Rory filed that away — there was always more to Nyx than they offered, and the grove had just offered something for free — and turned back to the meadow. They walked deeper. There was no path, only the press of flowers parting around their legs and closing behind, but Rory noticed something that made the back of her neck prickle. She left footprints, dark crushed swaths through the blooms. So did Eva. Nyx, half-solid, left nothing. The sound was the strangest part. The grove was not silent — far from it. There was a constant low music, almost too quiet to name: the chime of distant water, a thread of birdsong that never resolved into a melody, the whisper of leaves rubbing in a wind she couldn't feel. But there was no traffic. No planes. No London. The city of nine million souls that should have been roaring just beyond the trees had simply ceased to exist, as though the grove had stepped sideways out of the world and pulled the door shut after it. "How long do we have?" Rory asked. "In here." Nyx's glowing eyes swept the canopy. "Time runs crooked in the in-between. An hour spent here might cost us minutes outside." A pause. "Or days. The Grove does not keep our accounting." "That's the most useful unhelpful thing anyone's ever told me," Eva muttered. They came to a stream. It ran clear over stones that were not stones — when Rory crouched and looked closely, she saw they were pale and rounded and faintly translucent, with a milky inner light, like moonstones tumbled smooth. She reached toward the water and Nyx's voice cut the air, sharp as a hand on her wrist. "Don't drink. Don't eat anything you're offered. Whatever you do here, take nothing without giving its price." She drew her hand back slowly. The water sang on over the glowing stones, indifferent. It was Eva who saw her first. "Rory." Just her name, gone thin and small. On the far side of the stream, where the meadow rose into a low bank crowned with hawthorn, a figure stood among the flowers. She had not been there a moment ago — Rory was nearly certain. Silver hair spilled past her waist, catching the sourceless gold and throwing it back like spun metal. Her eyes were the pale lavender of the crocuses at her feet, and they were fixed on Rory with an attention that felt physical, a weight settling over her shoulders. She made no sound as she came down the bank. And though the flowers bent around the hem of her gown, Rory looked down and saw what she had half expected and still found chilling: where the woman walked, the bluebells sprang back upright at once, unbruised. She left no mark of her passing at all. "You've come a long way," the Seer said, and her voice was warm and amused and ancient all at once, "for answers you already carry. Welcome, daughter of two shores, shadow that was a man, and the one who runs and does not yet know toward what." She inclined her head, that long silver hair sliding. "The Grove has been expecting you. It is impolite to keep a question waiting." Rory's hand drifted, unbidden, to the cold leaf-shaped weight at her hip — the moonsilver dagger she did not yet know was a gift, did not yet know was hers to keep. Isolde Varga's lavender eyes followed the movement, and she smiled like someone watching a story arrive precisely on its appointed page. "Yes," she said. "That, too. But first — walk with me. There is so little of it left to waste."
