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.

By the time Isolde stopped walking, Richmond Park had gone almost black with evening. The last of the London light lingered low and dirty at the horizon, caught in bare branches and the distant iron trace of the city, but under the trees the world had already narrowed to damp earth, cold breath, and the pale flash of Isolde’s hair ahead. Rory had expected theatrics. A hidden door in a hill, maybe. A ring of mushrooms. Something that announced itself. Instead there were only trees, old enough to look opinionated, and a scatter of lichen-crusted stones standing among them in a rough oval. Oak roots had heaved the ground around their bases. Moss furred the cracks. At first glance they might have been just another half-forgotten ruin buried in English soil. Then Rory stepped closer and felt the air change. Not colder. Not warmer. Denser. Like walking toward deep water. Beside her, Nyx drew still. In the weak spill of dusk they were almost invisible, their tall shape thinning and thickening with every stir of shadow between the trunks. Only their eyes held steady, two faint violet points in the dark. “This place dislikes being looked at directly,” they murmured. Their voice brushed the air more than it crossed it, like somebody whispering through a keyhole. Rory touched the pendant at her throat without thinking. The Heartstone sat warm against her skin, warmer than it should have been in the January chill. Its deep crimson center held a faint, banked glow, as if a coal had been trapped inside it and taught patience. That unsettled her more than the stones did. Isolde glanced back over one narrow shoulder. In the dusk her pale lavender eyes seemed to gather what little light remained. “Thresholds are shy creatures,” she said. “They open for those who arrive with hunger and close for those who arrive with certainty.” “Good,” Rory said. “I’m starving and deeply unconvinced.” For the first time all evening, Isolde smiled. Up close, the standing stones were stranger than they had looked from a distance. They were not carved, exactly, but the wood-grain pattern running through the rock gave them the appearance of something halfway between oak and stone, as if the boundary itself had changed its mind several times before settling on its present shape. Fine silver lichen traced the edges. Between two of the tallest stones, the darkness wavered. Rory squinted at it. A faint shimmering hung there, a distortion so slight it vanished whenever she tried to pin it down. Heat haze on a winter night. Glass seen through water. The hairs lifted on her arms. “The Veil,” Nyx said softly, following her gaze. Rory swallowed. She had heard the word often enough these past months, always in the tone people used for things that were both obvious and impossible. Seeing it—if seeing was the right word—made her stomach tighten. “Will it hurt?” she asked. “Only if you insist on belonging entirely to one world,” Isolde replied. “That is not an answer.” “It is the truest one you will get.” Of course it was. Isolde stepped between the stones first. She did not push through the shimmer so much as become briefly less solid, her silver hair blurring to moonlight, her long dark dress trailing after her without a sound. Rory looked down automatically to mark where she had gone and saw nothing on the frost-dusted ground beyond the threshold. No footprint. Not even a bent blade of winter grass. Right. Half-Fae. Rory flexed her fingers once, then drew a breath and went through. The world folded. That was the only word for it. The park, the trees, the wet smell of London soil, the distant hiss of tires on road—everything drew inward like fabric pinched between unseen fingers. Cold pressed over her skin. For one sick, floating instant she had no sense of up or down. Her scar prickled on her left wrist, the old crescent line going hot. Then the pressure released. She stumbled forward onto springy ground and caught herself. Silence hit next. Not total silence. Worse. A layered hush full of things she could not identify: a high chiming in the branches, as if glass tapped against glass; the far murmur of water moving uphill; the fluttering rustle of leaves though the air stood still. But the ordinary sounds of the park were gone as cleanly as if a door had shut on them. Rory straightened slowly. The grove opened around her. Wildflowers spread beneath the trees in impossible, reckless abundance—bluebells and foxgloves, poppies, crocuses, roses still beaded with dew, white star-shaped blooms she had no name for. They should not have shared a season, let alone a patch of ground. Yet here they crowded together, bright as spilled paint across the moss. The trees themselves rose silver-barked and immense, their branches arching so high they disappeared into a soft amber glow overhead. Amber. Rory looked up sharply. There was no proper sky. Not the one she’d left, anyway. Above the interlocking canopy hung a warm, lucid light, like sunset stretched thin and fixed in place. It painted the leaves gold at their edges and turned the air itself to honey. “Bloody hell,” she said. Nyx slipped through the threshold at her shoulder. Inside the grove they were more visible, though no less strange. The shadows beneath the trees clung to them, eager as hounds, shaping the outline of long limbs and a narrow face that never quite finished becoming human. They tilted their head back toward the amber light. “This is not entirely Earth,” they said. “No,” Rory said quietly. “I’d gathered.” Ahead, Isolde moved soundlessly through the flowers. They did not bow under her feet. They did not bend at all. Rory looked back once. The standing stones were still there, but what lay between them now was not the dark wood she had come from. The gap held only a wall of pearly mist, dense enough to hide everything beyond it. That was new and deeply unhelpful. “Please tell me the way back stays where we left it,” she said. “The way back stays where it pleases,” Isolde answered. Rory let out a breath through her nose. “Fantastic.” They followed Isolde along a path that at first Rory thought was bare earth. Then she saw it was made of flattened petals, pressed into the shape of a winding trail by countless feet—or whatever passed for feet here. The flowers to either side leaned as they passed, not toward Isolde, not toward Nyx, but toward Rory. Their movement was slight, almost insect-small. Enough. She kept her hands to herself. The deeper they went, the stranger the grove became. Great ferns uncurling silver fronds from black soil. Pools no larger than dinner plates reflecting not branches but drifting constellations. A fallen log split open to reveal glowing amber sap that smelled faintly of cinnamon and rain. Every few yards Rory found herself stopping to stare at something she could not fit into the tidy filing cabinet of the ordinary world. Once, a flock of tiny birds burst from a bush in a shimmer of translucent wings. They flew soundlessly across the path and vanished into the bark of a nearby tree as though wood were merely another kind of air. Rory blinked hard. “Did you see that?” “Yes,” Nyx said. “Good. I’d rather not be hallucinating alone.” “Hallucinations are usually more personal.” “That’s comforting.” A low branch brushed her shoulder. The leaves were cool as skin. When she looked closely, each one held a vein of pale light that pulsed once, slow and deliberate, before fading. The Heartstone pendant gave another faint throb of warmth. She stopped walking. Nyx stopped too, instantly alert. “What is it?” Rory touched the gem through her shirt. “The pendant.” Isolde turned but did not come back to them. Her silver hair spilled over one shoulder like water. “Stones remember roads,” she said. That was not an answer either, but Rory had learned by now that pressing Isolde for a straight line only earned a prettier maze. She scanned the grove. At first she saw nothing except flowers and tree trunks and that impossible amber wash overhead. Then, a little way off the path, the air bent. There it was again—that same fine trembling she had seen between the standing stones, but stronger here, enough to warp the line of a trunk behind it. The shimmer hung between two yew trees whose bark had grown together into a dark arch. Beneath it, the moss had blackened in a rough circle. Cold slid down Rory’s spine. Nyx drifted nearer the place and then halted. Their form rippled, edges fraying. “A tear,” they whispered. “Not open. Not yet.” The pendant had gone hot
