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 rose out of the bracken like the bones of some long-dead giant, ancient oaks twisted into pillars taller than any tree had a right to be. Rory stopped at the threshold of them, her breath fogging in air that shouldn't have been cold. It was June. Behind her, the ordinary green sprawl of Richmond Park hummed with the distant noise of London — traffic, a dog barking, a child shrieking with laughter. In front of her, past the gap between two leaning oaks, there was only silence. "You're certain this is it," she said. It wasn't really a question. Nyx flowed up beside her, their shadow form thinning at the edges where the late sun touched it. In the open daylight they were little more than a smudge of darkness wearing the shape of a tall man, their violet eyes the only thing that held color. "I can feel it," they whispered, and their voice did what it always did — slid past her ears like wind through a keyhole. "The boundary. It's thin here. Old magic, the kind that doesn't answer to anyone." The third member of their company, Eva, hung back with her arms wrapped around herself. She'd insisted on coming. Rory had let her, against her own better judgment, because Eva had a way of refusing to be left behind that made arguing pointless. "It's just a circle of trees," Eva said, though her voice wavered. "Then walk through it," Nyx murmured. Eva didn't move. Rory reached up and pressed two fingers to the Heartstone pendant where it lay against her sternum. It had been warm all afternoon, a low pulse of heat she'd half-convinced herself she imagined. Now, this close to the stones, it throbbed like a second heartbeat, insistent and alive. She let out a slow breath, squared her shoulders, and stepped between the oaks. The world changed. It was not gradual. One foot fell on ordinary park grass, dry and yellowing in the summer heat, and the next came down on something soft and impossibly lush — a carpet of moss and wildflowers that should not have been blooming all at once. Bluebells and foxgloves, primroses, things she had no names for, all of them open and vivid in the same breath of season. The cold vanished. The air turned thick and sweet, heavy with pollen and the green smell of growing things, and underneath it something older, mineral, like wet stone in a cave that had never seen the sun. Behind her, Eva's gasp cut off as she crossed the threshold. Then Nyx, and the Shade made a sound Rory had never heard from them — something between a sigh and a shudder. "Oh," Nyx breathed. "Oh, I'd forgotten." The grove opened before them like the inside of a cupped hand. The clearing was wide, ringed entirely by those ancient oaks, and overhead the sky was wrong. It was the deep gold of late evening, though it had been midafternoon a moment before, and the light came from everywhere and nowhere, casting no honest shadows. Motes drifted through the air, slow as ash, catching the gold and holding it. When Rory turned to look behind her, the gap they'd come through was still there — but past it, the park looked grey and distant, washed of color, as though she were seeing it through dirty glass. "Don't lose sight of the way out," she said. Her voice came out hushed. The grove seemed to demand it. Eva crouched and touched the moss, then snatched her hand back. "It's warm," she whispered. "The ground's warm. Like skin." Rory moved deeper, slow, every sense stretched taut. The grass made no sound beneath her boots, swallowing her footsteps whole. When she glanced down she saw the wildflowers spring back upright behind her, as if she'd never passed at all — and beside her own faint tracks, there was nothing. No prints from Nyx, who walked on air half the time anyway. But the seer's words came back to her, the thing Isolde had said once, that she left no mark on the world when she walked. This was her place. They were inside it now, guests in something that breathed. A stream cut through the center of the clearing, narrow and quick, and the water in it ran the wrong way — uphill, toward a low rise, defying every law Rory had ever trusted. She stood at the bank and watched it climb, silver and chuckling, and felt the hair lift along her arms. "Don't drink it," Nyx warned, drifting close. "Whatever you do. Fae water doesn't fill you. It empties you." "Wasn't planning on it." But she crouched anyway, drawn, and saw her own reflection waver in the racing surface — and behind her face, for just an instant, another. Pale lavender eyes. Silver hair like spilled mercury. Then the water rushed on and the reflection was only Rory again, dark hair, blue eyes, the small crescent scar pale on the wrist she'd braced against the moss. She stood up too fast. "You felt that," Nyx said. Not a question. "She knows we're here." Rory's hand had drifted, without her deciding it, to the Fae blade sheathed at her hip. The moonsilver was cold even through the leather, cold the way the grove was warm, a deliberate wrongness. It hummed faintly against her palm, recognizing its own country. Isolde had given it to her with a riddle and a warning, and now Rory understood the warning better than the riddle: a weapon of the Courts would always want to come home. The wildflowers ahead of them bent. Not from wind — there was no wind — but in a slow ripple, a path opening through the blooms like a parting in long hair, leading toward the rise where the stream climbed and vanished into a stand of hawthorn heavy with blossom out of season. Eva edged closer to Rory's shoulder. "That's an invitation, isn't it." "Or a snare," Nyx murmured. "With the Fae, the difference is mostly a matter of timing." Rory looked at the parting path, at the gold light pooling in the hawthorn shadows, at the pendant glowing through the fabric of her shirt with a steady crimson pulse. Wonder and dread sat side by side in her chest, indistinguishable. Somewhere in this impossible clearing, in the pocket between one world and the next, a three-hundred-year-old woman who could not lie was waiting to tell her something true. "We didn't come this far to stand at the edge," Rory said, and stepped onto the path. The flowers closed behind her like a held breath finally let go.
