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.

Twilight pressed against Richmond Park, but the clearing before Aurora Carter didn’t
seem to
care about human hours. She brushed a stray strand of black hair from her brow, wary, and glanced back at her companions. Nyx hovered mid-step, a silhouette stitched from dusk, while Isolde Varga watched with moonlit composure, her silver hair drifting like mist in a wind only she could feel. Oak trunks reared above them, impossibly ancient, thicker than any she’d seen in Wales or London. They stood in a circle, bark
furrowed
in whorls that suggested faces and time: the ancient standing stones Isolde had spoken of, except alive. Each bough curved to join its neighbors overhead, webbing the sky in a cathedral of green, the leaves flickering with light that wasn’t sunlight—more a liquid glow, lantern gold and fae-blue, dappling the mossy ground. For a heartbeat, Rory’s blue eyes caught the shimmer at the grove’s edge—the Veil, she realized, though to her it was just the faint prickle on her skin, like the charge before a storm. She steadied her breath. Even after everything—the night a demon grinned through Evan’s face, the knife Isolde slipped her in a café—she still felt the edge of disbelief gnawing at her heels. Isolde
glided
forward. She left no mark upon the spongy emerald moss, her steps exquisitely silent. “This way,” she murmured, the words curling out like a challenge and a promise. Nyx
flickered
at Rory’s side, their humanoid shape ragged at the edges, violet eyes glowing like will-o’-the-wisps. Not-shadow, not-light—she’d given up trying to pin them down. “If you sense the shape of watches turning, ignore it,” Nyx whispered, their voice a caress right against her ear. “Time here
dances
in spirals, not lines.”
The air was thick with
scent: wild honeysuckle, distant apple, a drifting undercurrent of rain and clover. The wildflowers scattered underfoot in a thousand colors, riotous and impossible for March. Rory knelt to touch a blossom—bluebells and foxglove, cheek by jowl with wild orchids that shouldn’t bloom for months. Petals felt cooler than the air, as if each drew its breath from a different season. A gentle breeze swept through, carrying laughter not quite belonging to any of the three of them. Rory’s hand went to the silver chain at her neck, fingers brushing the Heartstone pendant. Its deep crimson gleam pulsed once, as if the grove’s strangeness had woken it. The warmth radiating into her chest steadied her. Birdsong
echoed
from somewhere above, unearthly bright. She tracked it upward, heart stuttering as she glimpsed the source: birds made of glass and silver, their wings refracting the not-sunlight. They sang in chords rather than melodies—three notes rising, three notes falling, punctuated by the soft susurrus of leaves. Isolde paused beside a stream so clear Rory could see every pebble, every thread of root twining under its surface. The water carried an odd luminosity, moon-silver even here in this perpetual half-light. She knelt to fill her palms, then offered the cupped water to Rory. “Drink deeply but not greedily,” Isolde intoned, as if quoting an edict. “Else the Grove will keep you long past your wish.” Rory hesitated. The water
shimmered
with patterns she almost recognized—her mother’s handwriting, a petal from her child-lost camellia, newspaper fragments from a past life. For an instant, she saw Evan’s mouth twist into a sneer, the kitchen light flickering. She blinked, throat tight, and drank. The taste was cool and bright—summer rain on tin, clover honey, something fiercely alive. Nyx declined water, instead drifting farther, their feet slivering silent as smoke. They pressed a hand—if it could be called that—into the trunk of a twisted birch, their form bleeding shadow into silvered bark. “The boundaries here are… soft,” they murmured, voice barely audible. “I could step to a hundred places at once, but none would be home.” Something rustled at the edge of the grove, and Rory braced. Shapes watched—a fox with curls of ivy for fur, a stag painted in moonlit dapples, eyes too knowing for animals. Their gazes lingered, more curious than afraid. “It’s safe,” Isolde said, with a smile that meant everything and nothing. They followed an almost-path, a suggestion between pillars of oak. Here and there, the ground sloped into hollows of wild violets or up into hummocks crowned with tiny, bell-shaped flowers Rory didn’t know the names for. She brushed a fern and the frond chimed like a crystal glass. Time frayed. At some point, Rory realized the quality of light had shifted: the sky was neither day nor night, but a deep violet streaked with amber, the colors somehow bleeding in from memories she couldn’t quite reach. She checked her phone—dead, of course, its black face reflecting not herself but a younger girl, missing her scar. Halfway into the grove, the hum of the world thickened, the air grown heavier. A standing stone
loomed
before her—oak petrified into something like
marble
, a surface inscribed with looping, ancient script. Rory touched the carving, and for a moment felt it pulse: her mother’s lullaby in Welsh, the sharp tang of a barrister’s words in court, the ache of loss and hope. “She left a mark for every seeker,” Isolde said
softly
, her gaze unfathomable. “The Grove learns your story. Sometimes it returns it changed.” Beyond the stone, an opening yawned in the undergrowth—an arch woven from branches in full flower, dew trembling on petal and thorn. Nyx strode ahead, unfazed, and the arch whispered around them, every blossom opening wider. Rory hesitated. “Once I go, can I come back?” she asked. Isolde tilted her head, silver hair swinging like a spill of moonlight. “If the Grove so wishes. Its doors prefer honesty, not promises.” That, at least, was clear as anything in this place wasn’t. She stepped through the arch, half-expecting vertigo or music or pain. Instead, a hush fell. The Grove here was deeper—more itself. A ring of tiny mushrooms circled a boulder cut by a spill of light, and in that light, for just a second, Rory glimpsed figures moving: a child skipping, a woman mourning, someone
dancing
in abandon. Her own face, older and younger both,
shimmered
and
was gone
. The air crackled with possibility. She heard Nyx’s whisper, close enough it teased her ear. “You see the bones of the place. Few mortals do.” Her breath fogged in the cold, but didn’t quite touch the world. She bent, fingertips brushing the mushroom ring. The cold bit her—colder even than the Fae-forged blade sheathed at her side—yet not unpleasant. Energy rushed up her arm, memory burning: the dark of a London alley, Yu-Fei laughing over dumplings, Eva’s arms around her, safety and loss twined too
tightly
to untangle. She let herself stand. Isolde moved to her, a gentle tilt of the head. “There is a heart to this place, beating under the moss,” the Seer said. “Do you wish to see it?” Rory nodded, words lost somewhere between her tongue and her thoughts. Isolde gestured. Petals stirred and parted, revealing a hollow in the earth, roots snaking down into darkness. At its center, a stone slab glowed the color of old parchment, pulsing in time to some slow, inexorable rhythm. All around, flowers bent inward, as if listening. Nyx stood at the edge of the hollow, their shape suffused with the Grove’s strange light. “What do you remember, here, Aurora Carter?” There was nothing unkind in the question—only the
weight
of distance. She knelt, feeling the moss damp beneath her knees, and placed the Heartstone pendant atop the slab. It flared, deep crimson burning through pale gold, and for a moment she felt her heart beating in time with the Grove: loss and hope—root and leaf, wound and healing—balancing on the edge of something new. Wind swept through the standing stones, carrying music she did not know how to name. She was sure that, for as long as she knelt here, she could not lie to herself, and that nothing she left buried would stay hidden long. Wonder coursed through her, tangled with unease. This was a place that saw her—
truly
, impossibly saw her—and offered its secrets in answer. Somewhere high above, the glass birds sang on, their notes threading through the light, through her, through the everything. And for Rory, for a moment, that was enough.
