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 oak stones stood at the edge of the bracken like a row of patient old men, their bark furred with lichen the color of weak tea. Rory counted them without meaning to. Eleven. She was sure there had been ten when she'd walked the path with Isolde's directions folded in her coat pocket, and she was less sure now that it mattered. "Don't count them," Isolde said, not looking back. "They enjoy being miscounted." The Seer walked ahead of them, silver hair loose to her waist and catching what little light came through the canopy. Her feet made no sound in the leaf litter. Rory watched for the faint crush of dead bracken beneath her boots and saw nothing, not even a flattened stem where Isolde had passed. It was the sort of detail she would have dismissed a month ago. Now she filed it away with the others. Nyx drifted at the rear. Rory felt rather than saw them: a cooling at her back, a stretch of shadow under the trees that lingered a half-second too long after the trunks above had moved on. When she glanced over her shoulder, the shape resolved into a tall silhouette, six feet and some inches of living dark, faintly violet at the places where eyes should be. "You're staring," Nyx whispered. The voice seemed to arrive on a breeze that wasn't there. "You're shadowing me." "I am the shadow. It's a considerable difference of perspective." Rory huffed something that wasn't quite a laugh and turned back to the path. Her left wrist ached faintly, the old crescent scar pulling the way it always did when her nerves were stretched thin. She flexed her fingers. The Fae blade sat snug against her hip under her jacket, its moonsilver cold even through the lining, as it had been since Isolde pressed it into her hands. Beneath her collarbone, the Heartstone pendant lay quiet on its silver chain. It had been quiet all the way from London. She had half hoped it would stay that way. Then the trees opened, and she forgot the pendant entirely. The clearing was not large, but it did not seem to have edges. The grass rolled away in soft folds, and every fold was crowded with flowers: foxglove and primrose, harebells, clusters of white star-shaped blooms she didn't recognise, all open at once in a season that had no business being spring. Frost should have been silvering the ground in late autumn, and instead the air was warm and smelled of crushed thyme and rain that had not yet fallen. Butterflies the colour of stained glass turned lazy circles above the blossoms. "Wildflowers bloom here year-round," Isolde said. She had stopped at the centre of the clearing, where a single ancient tree stood, its trunk split into three trunks that rose and twisted together like a braid. "Do not pick them. They do not wilt, but they do remember who has touched them." "That's not ominous at all," Rory said. "It is not meant to be ominous. It is meant to be remembered." Isolde smiled, and her pale lavender eyes creased at the corners. "You will forget that soon enough. Everyone does." Rory crouched to look at a cluster of blue flowers near her boot. Each petal was edged with a fine silver line, like frost on glass, and when she leaned closer she heard it: a faint, high chiming, so quiet it might have been her own pulse. She stood quickly, shoved her hands into her pockets, and did not look at the flowers again. Nyx had drifted to the edge of the clearing, where the shadows under the trees were thick as wet ink. They did not move, which was itself unsettling, since Nyx never stayed still. "Rory," they said softly. "Come here. Look at the ground." She went. Between two roots, the earth had split into a fissure no wider than her palm, and the light that rose from it was not sunlight. It was amber, warm and shifting, like the glow of a lamp seen through honey. The air above it smelled suddenly of roasted meat and wine and something sweet that made her mouth water against her will. Somewhere far below, faint and rhythmic, a bell was ringing. "Dymas," Isolde said quietly behind her. "Not a door. A window. Be glad it is shut." The pendant at Rory's throat flared warm against her breastbone. It was not painful, only insistent, a heartbeat pressing outward through the silver chain. She pressed her palm over it. The warmth pulsed once more, then sank back into a steady glow. "Right," Rory said, and was surprised by how steady her own voice sounded. "I think I'd like to know what time it is." Isolde's smile deepened. "Time is a courtesy this place extends to guests. Check your watch in an hour, and you may find you have been gone a day. Or a week. Or no time at all." She turned toward the split tree, and the light caught her silver hair like spun wire. "Come. We are not here to stare at the ground. There is something you need to see before the grove decides you have seen enough." Rory took one last look at the amber light, at the chiming flowers, at the shadow that was Nyx keeping watch beside her. Then she followed the Seer into the braided shade, and the warm air closed behind them like a held breath.
