System
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 air inside the grove was thick with the scent of damp earth and something sweeter—like crushed petals and honeyed wine. Rory stepped through the standing stones first, her boots sinking
slightly
into the mossy ground, the Heartstone pendant warm against her collarbone. The moment she crossed the threshold, the world behind her blurred, as if seen through warped glass. She turned back, but the path they’d taken was already gone, swallowed by a curtain of ivy and silver-barked trees. Nyx slipped through after her, their form flickering like a candle flame in a draft. The shadows here clung to them differently, deeper, as if the grove itself recognized what they were. *"This place remembers,"* they murmured, their voice a breath against Rory’s neck. *"It remembers the old magic."* Isolde followed last, her silver hair catching the dappled light like a spider’s
silk
. She moved without sound, her bare feet leaving no imprint on the loam. *"Walk
softly
,"* she said, though her voice carried no warning—only the quiet certainty of a woman who had seen this moment a hundred times before. *"The grove listens."* The trees here were not like the oaks and elms of Richmond Park. Their bark
shimmered
with an iridescent sheen, shifting between deep emerald and violet as the light touched them. Their leaves, broad and veined with gold, rustled without wind, whispering in a language just beyond understanding. Rory reached out, brushing her fingers against one. The leaf
trembled
, and for a heartbeat, she swore she felt it *breathe*. *"Careful,"* Nyx warned, though they didn’t stop her. *"Some things here are alive in ways you don’t yet understand."* Rory pulled her hand back, but not before the leaf curled around her fingertip, cool and damp, like the inside of a mushroom. She exhaled
sharply
. *"Right. No touching."* Isolde smiled, a slow, knowing thing. *"Oh, but you will. You all will. That is the way of this place."* The deeper they went, the more the grove
seemed to
shift around them. Paths that had been straight moments before now curved, leading them in directions they hadn’t intended. The standing stones—ancient, moss-covered, carved with spirals and symbols that made Rory’s eyes ache if she stared too long—marked the edges of the clearing, but the clearing itself
seemed to
expand, revealing more of itself with every step. A stream cut through the center, its water so clear it was nearly invisible, reflecting the sky in a way that made Rory’s head spin. She crouched, dipping her fingers in. The water was neither warm nor cold, but *alive*, humming against her skin like a plucked string. When she pulled her hand back, her fingers were dry, as if the stream had never touched her at all. *"It’s testing you,"* Isolde said, watching her. *"Deciding if you’re worthy."* *"Worthy of what?"* Rory asked, standing. Isolde didn’t answer. Instead, she tilted her head toward the far side of the clearing, where the trees parted to reveal a structure Rory hadn’t noticed before—a circle of smooth, black stones, each carved with the same spiraling symbols as the standing stones. At its center stood a pedestal, and upon it rested a dagger. Not just any dagger. The Fae-forged blade. Rory’s breath caught. The weapon was slender, its edge curved like a leaf, its surface catching the light in a way that made it seem as though it
were carved
from moonlight itself. A faint glow pulsed along its length, in time with the heartbeat Rory
suddenly
realized she could feel in her own chest. *"That’s—"* she started. *"Yours,"* Isolde finished. Nyx let out a low, amused sound. *"Of course it is."* Rory hesitated. The air around the pedestal thrummed with energy, like the moment before a storm breaks. She could feel the
weight
of the grove’s gaze on her, the trees leaning in, the stream holding its breath. *"Take it,"* Isolde urged. *"It was made for your hand."* Rory stepped forward, her boots silent on the moss. The closer she got, the colder the air became, until her breath misted in front of her. The dagger’s glow intensified, casting eerie blue shadows across the stones. She reached out— —and the moment her fingers brushed the hilt, the world *shifted*. The grove vanished. She
was standing
in a vast, amber-lit hall, the air thick with the scent of roasting meat and spiced wine. Demons in fine
silk
s lounged on cushions, their laughter rich and deep, their eyes
gleaming
with hunger. At the far end of the hall, a figure sat upon a throne of blackened bone—a prince, his face sharp and beautiful, his smile sharp and cruel. *"Ah,"* he said, his voice like honeyed venom. *"The little thief has come at last."* Rory’s stomach
lurched
. She knew this place. She’d seen it in her dreams. Dymas. The vision shattered like glass. She was back in the grove, gasping, the dagger clutched in her hand. It was cold, so cold it burned. She nearly dropped it, but her fingers refused to let go. *"What the hell
was that?"* she
demanded, her voice raw. Isolde’s expression was
unreadable
. *"A warning. Or an invitation. The Fae blade shows you what you fear—or what you desire."* Rory’s grip tightened. *"I don’t want anything from *that* place."* *"Don’t you?"* Isolde’s pale eyes gleamed. *"The Heartstone led you here. The blade chose you. The grove *called* you. Tell me, Aurora Carter—what do you think all of that means?"* Rory didn’t have an answer. But the dagger in her hand pulsed, once, twice, as if in agreement.
