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 appeared between one stride and the next. Aurora stopped so abruptly that Eva bumped into her back. The path behind them ran through Richmond Park beneath a low ceiling of winter cloud; ahead, the earth dipped into a clearing ringed by ancient oaks. Their trunks were too broad to belong to any tree Rory had ever seen, their bark ridged and black as old armor. Between them stood the stones: a dozen upright slabs, each tilted at a different angle, their surfaces pale with lichen. The air beyond the boundary shimmered. Not like heat above a road. It quivered with a silver-blue sheen, bending the view of the clearing as if the world there sat beneath a skin of water. Rory’s fingers closed around the cold hilt of the dagger at her belt. Its moonsilver edge pressed through the leather sheath, colder than the air. Eva leaned around her. “That’s it, then?” “I think so.” “You think so.” Rory glanced back at the trail. There was no sign they’d walked far enough to find anything unusual. A crow called somewhere in the park. Traffic hissed beyond the trees. Ordinary sounds. Ordinary earth. But the crimson pendant against Rory’s chest had begun to warm, its faint inner glow staining the hollow of her throat red. She slid it beneath her jumper. At her left, Nyx stood half in the shadow of an oak, a tall silhouette with violet eyes. Their outline wavered at the edges, as if the day’s dimness had gathered itself into the shape of a person. “The seam is thin,” they whispered. Their voice seemed to travel from farther away than their mouth. “It has been touched many times.” “By people?” Eva asked. “By things that do not walk as you do.” Eva’s hand tightened around the strap of her satchel. She had insisted on coming, though she’d been pale ever since Rory told her what Isolde had said: that the grove would open when the heart knew the way in. It was the sort of prophecy that sounded clever until you had to act on it. Rory took one breath, then stepped between the stones. The air folded over her. For a moment she felt the boundary drag across her skin, cool and fine as silk pulled through her fingers. A pressure touched the back of her eyes. The noise of the park dropped away—not faded, exactly, but cut off, as if a door had shut behind them. Eva stumbled through after her with a sharp gasp. Nyx crossed last, their shadow stretching between the stones before drawing itself into solid form on the far side. The clearing was larger than it had looked from outside. The oak trees stood in a wide circle, their branches interlaced overhead, though there was no sky between them. Instead, a pale, depthless glow seeped through the leaves. The wildflowers at their feet were in bloom, blue and white and gold, their petals bright against the frost-silvered grass. Rory caught the scents of crushed mint, rain on stone, and something sweet she couldn’t name. She looked back. The standing stones were still there, but the park beyond them had vanished. Between the slabs hung a smooth curtain of silvery haze. No trail. No bare branches. No grey London sky. Eva swore under her breath. “Don’t panic,” Rory said. “I’m not panicking.” “You’re gripping that bag hard enough to strangle it.” Eva loosened her hand. “I’m taking the place seriously.” “That’s sensible.” Rory turned away before her friend could make her smile. The dagger’s coldness had sharpened against her hip. She touched the pommel to make sure it was still there, then started forward. The grass bent under her boots but did not break. Flowers nodded in her wake, their heads following her as she passed. When Rory looked back, they were facing the other way again. “Did you see that?” Eva whispered. “I did.” “Good. I was worried I’d started seeing things.” “Not yet,” Nyx said. The trees thickened around them. Their trunks twisted together, forming archways and narrow corridors. Some bore deep marks, too regular for natural scars: three cuts beneath a circle, a line of tiny hooked symbols. Rory recognized none of them. When she held the Heartstone close, its warmth came in pulses against her palm. The pendant brightened. Nyx turned toward the darker stretch between two oaks. “There.” A gap in the trees opened ahead, though Rory could have sworn there had been no path when she first looked. She glanced at Eva. “Following the ominous opening,” Eva said, “is how people in stories get eaten.” “Then we’ll keep our eyes open.” “Comforting.” They moved on. The grove changed by inches. The trees thinned, and the ground began to slope down. A stream wound through the hollow, its water clear as glass, its bed strewn with white stones. Rory crouched at the bank. In the stream’s reflection, the trees overhead were full of stars. She looked up. The same pale glow shone through the leaves. “Don’t drink,” Nyx murmured. Rory withdrew her hand from the water. “Wasn’t planning to.” “Good. It remembers what touches it.” Eva stepped closer to peer into the stream. “What does that mean?” The water rippled, though nothing had disturbed it. For one breath, Rory saw a face beneath the surface. Not a reflection. A young woman’s face, eyes shut, hair streaming around her as if she floated in deep water. Then the current swept it away. Eva recoiled. “All right. Not drinking.” A bridge crossed the stream a little farther on. It was made from the curved spine of something enormous, ivory-white and polished smooth by time. Rory stood at its edge and felt the hair rise on her arms. “Can we know what it was?” Eva asked. “No,” Rory said. “And I don’t think I want to.” They crossed one at a time. The bone flexed under Rory’s boots, though it made no sound. Midway over, the pendant flared hot enough to burn through her jumper. She clamped a hand over it. Across the stream stood a circle of smaller stones, half buried in moss. At their center, a tree grew from the bare rock. Its trunk was silver-grey and forked into two great branches, one covered in green leaves, the other bare and black. At the joining of the branches, a narrow crack split the wood. Something shone inside it. The shimmer of the Veil. Rory felt it before she could make sense of what she was seeing: a faint distortion, like the air above a flame. The crack widened and narrowed with each pulse of her pendant. Through it came a breath of hot, metallic air. Nyx went very still. Their violet eyes burned brighter. “A wound.” “The Veil?” Rory asked. “Yes.” She drew the Fae-forged blade. The moonsilver caught a glow that wasn’t there a moment before. Its leaf-shaped edge showed pale and keen, cold enough to sting her palm through the grip. Eva stared from the blade to the split in the tree. “Can that fix it?” “I don’t know.” “Excellent. A mystery and a potentially world-ending crack. We’re having a great afternoon.” Rory edged toward the tree. The grass around its roots had browned in a perfect ring. Beyond that circle, the flowers leaned away from the trunk. The air smelled of ash and overripe fruit. The Heartstone thudded warmly against her chest. A sound came from the crack: the scrape of something dragging across stone. Nyx slipped forward, their body losing its edges. Shadow poured from their feet and stretched beneath the tree. “Stay back.” The scrape came again. A point of darkness pressed against the opening from the other side. It had the blunt, jointed shape of a finger. Rory’s grip tightened on the dagger. The finger withdrew. The crack in the tree snapped shut with a dry, wooden click. The heat vanished. The pendant dimmed against her skin. For a long moment none of them moved. Then, from somewhere deeper in the grove, a bell rang. The note rolled through the trees, clear and low. It seemed to pass through Rory’s bones, leaving each one humming. The silver branches trembled. All around the clearing, flowers turned toward the sound. Eva swallowed. “Was that meant to happen?” “Nothing here is meant for us,” Rory said. Nyx re-formed beside her. “Someone knows we have arrived.” “Someone friendly?” Eva asked. Nyx’s silence answered. Rory looked around the hollow. The path ahead led between two leaning trees, toward a distant rise where small lights glimmered beneath the branches. They could go back to the stones. They could find a way out, return to the park, and tell themselves they’d seen a strange place and survived it. But the bell had called from deeper within. And beneath Rory’s palm, the Heartstone had begun to pulse again—not with warning this time, but with a steady, almost eager warmth. She slid the dagger back into its sheath. “Stay close,” she said. Eva gave a thin smile. “I’m not letting you wander off into a haunted wood alone.” Nyx stepped ahead, their violet eyes fixed on the lights. “The grove has opened its first door.” Rory followed them down the path. Overhead, the branches knit together, hiding the way back. The wildflowers brushed her legs, cold and soft as breath. Somewhere beyond the trees, the bell sounded once more, and the whole hidden world seemed to lean in to listen.
