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 changed before they saw it. One moment, Rory
was stepping
over gnarled roots at the edge of Richmond Park, the chill of late autumn nipping at her cheeks. The next, the wind stilled, and the world
seemed to
inhale. She froze. Nyx, gliding beside her like smoke clinging to stone,
flickered
—its form momentarily thinning, as if caught between states. “We’re close,” they murmured, their voice like dry leaves skittering across pavement. “The boundary is thin here.” Aurora’s fingers brushed the Heartstone pendant at her throat. It pulsed once—warm, insistent—just as the trees ahead parted, not into more woodland, but into a clearing that should not exist. No, not a clearing. A threshold. Before them stood a ring of ancient oaks, not planted, but grown *wrong*—their bark deep silver, their branches arcing together high above as though woven by unseen hands. Between them, the air
shimmered
faintly, like heat rising off tarmac, but cold. The Veil. Rory had seen it only in fleeting glimpses—a distortion at the edge of vision, something her mind refused to hold steady—but here, it was *open*, rippling like liquid glass beneath a pale sun that cast no shadows. Isolde stood before the threshold, barefoot on moss that glowed a soft emerald underfoot. Her silver hair spilled like molten moonlight down her back, untouched by wind, as if suspended in time. She did not turn, but spoke anyway. “Only one step, and the world forgets you were ever gone.” Rory exhaled. “And when we come back?” Isolde tilted her head. “That depends on what you take with you.” Nyx passed through first—a ripple, a breath of darkness slipping between the stones. One second they were there; the next, simply *gone*, absorbed into the shimmer. Rory hesitated only a moment before stepping forward. Cold pressed against her skin, not the chill of winter, but something *older*—like the breath of a crypt forgotten for centuries. Her ears popped. The world folded, compressed, and then—* *Expanded.* She stumbled, catching herself on a root that didn’t feel like wood. It was smooth, warm, pulsing faintly beneath her palm like a living artery. She snatched her hand back. They stood in a grove unlike any on Earth. The trees were still oaks, but their trunks
shimmered
with veins of opal, their leaves not green, but a shifting
mosaic
of color—gold, violet, deep indigo—changing with the slow turn of some unseen light source above. The sky, if it could be called that, was neither day nor night, but a soft twilight shot through with constellations that moved—drifting
slowly
like schools of
luminous
fish. And the air—thick with the scent of wild mint, honeyed blossoms, and something metallic, like distant lightning. “Is this Fae Court?” Rory whispered. Isolde shook her head. “A fragment. A place forgotten. It remembers the old rules.” Rory’s pendant pulsed again—harder this time. She looked down. The crimson gem inside glowed faintly, its warmth spreading up her chest like a slow tide. “It’s reacting to something.” Nyx materialized beside her, form more solid now, yet still edged with shadow. Their violet eyes—two pinpricks of light in a face of shifting dark—scanned the trees. “This place is watching. Not hostile. But… curious.” A rustle came from the underbrush. Not leaves. Something *slithering*. Isolde lifted a hand. “Stay still.” From between the roots emerged a creature no larger than a cat—six legs, fur like spun obsidian, eyes like polished onyx. But its mouth—when it opened—was a ring of tiny, translucent teeth, chiming
softly
as it moved, like wind through glass bells. It circled them once, pausing before Rory. Sniffed the air. Then, impossibly, *spoke*, its voice a chorus of whispers: *“The heart sees what the eyes refuse.”* And then it vanished—melting into the moss, leaving only a faint hum in the air. Rory’s breath came quick. “What the hell was that?” “A memory,” Isolde said. “The grove speaks in
echoes
. It remembers those who passed through, or those it foresees.” Nyx crouched, trailing fingers through the moss. It flared where they touched, blooming with tiny flowers that opened and closed like breathing mouths. “This place is alive in ways Earth forgot. Not just the land. The air. The silence.” “Then why is it here?” Rory asked. “Hidden?” “Because the Veil thins where magic is strong,” Isolde said. “And this grove was once a doorway. Before the Wardens sealed the rifts. Before the Courts fell into exile.” She stepped forward, and the trees *shifted*. Not physically, but perceptually—Rory blinked, and
suddenly
the path ahead had lengthened, curving into a tunnel of interwoven branches. Above, the stars blinked in a new pattern. “Time is unreliable,” Isolde warned. “An hour may pass. Or a day. Or it may not pass at all.” Rory touched the Fae-Forged Blade at her belt. The moonsilver was cold—even here, where the air held a strange warmth. She drew it
slightly
, just enough to see the faint blue luminescence along the edge. In the shifting light, it pulsed like a slow heartbeat. They walked. The deeper they went, the more the grove unraveled reality. At one point, Rory saw her own reflection in a pool that wasn’t water—its surface mirror-smooth, yet rippling with colors not in the sky. Her face looked older, weary, a thin scar now running from temple to jaw. Then it
was gone
. Nyx stopped
suddenly
. “Listen.” At first, there was nothing. Then—music. Not from any instrument. From the trees. A low, resonant hum, deep as the earth’s core. It vibrated in Rory’s bones. The leaves
shimmered
in response, releasing a mist that
hung in the air
, swirling into shapes—faces, half-formed, whispering in languages she didn’t know but somehow *understood*. *“Lost ones. Found ones. Hungry ones.”* The pendant burned against her skin. “This way,” Isolde said, her voice distant, as if speaking from underwater. “The heartstone knows.” They followed her into a circular clearing, at the center of which stood a stone pedestal—smooth, worn, topped with a depression the exact shape of the pendant. Rory hesitated. Nyx drifted closer. “It wants you to place it.” “But what if I can’t take it back? What if it’s a trap?” Isolde smiled—
sadly
. “Nothing here traps you unless you choose to stay.” Rory unclasped the chain. The moment the pendant left her skin, the warmth vanished. The music dropped to a whisper. Even the stars dimmed. She placed the Heartstone into the depression. For a heartbeat—nothing. Then the pedestal *glowed*. Cracks spiderwebbed from the center, filling with crimson light. The grove *answered*. Trees groaned. The sky split—not violently, but like a curtain drawn aside. Through it, Rory saw *another* sky—not stars, but vast fields of amber wheat swaying under a warm, eternal sun. A river cut through it, thick with fruit-laden trees, and beyond—palaces of glass and fire. Dymas. The image held for only a breath before fading. The pedestal darkened. The pendant, now dull and cold, sat lifeless in its cradle. But the music didn’t stop. And the grove—bowed. The trees leaned inward, their opal veins pulsing. The moss rose in waves, forming symbols Rory couldn’t read, glowing gold, then vanishing. Isolde placed a hand on her shoulder. “You’ve been seen.” Rory’s voice cracked. “By who?” “The grove doesn’t serve one master. It *remembers*. And now, it remembers you.” Nyx stepped forward, their form
wavering
at the edges. “They’ll know you’ve been here,” they said. “The Wardens. The Courts. *Others*.” Rory picked up the pendant. It was cold now. Dormant. But beneath her fingers, just once, she felt it—*a pulse*. Not warmth. *Warning.* Isolde turned, her bare feet making no impression on the glowing moss. “Time to go.” And as they stepped back toward the ring of oaks, the grove behind them *closed*—the trees knitting together, the stars folding into themselves, the air sealing like a wound. But Rory could still feel it—the
weight
of observation, the whisper of chiming teeth, the image of amber skies and unseen feasts. And the knowledge, deep in her bones, that she had only just stepped through the first door.
