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 dimming sun cast long shadows across the ancient oak trees of Richmond Park, their gnarled branches stretching like skeletal fingers toward the fading amber sky. Aurora Carter, or Rory to her closest friends, stepped
cautiously
into the grove, her heart thrumming with
anticipation
. She had heard tales of this place, whispered legends among the city's mystics and outcasts. Now, she was about to experience it firsthand. The grove, known as Isolde's domain, was a hidden pocket between the mortal realm and the
ethereal
Fae lands. As Rory passed between the towering oak standing stones marking the boundary, an
uncanny
sensation brushed over her skin, like walking through a warm, invisible curtain. Goosebumps prickled along her arms, raising the fine hairs at the nape of her neck. "This way," Nyx whispered, their voice as insubstantial as the twilight around them. The Shade had agreed to guide Rory through the unpredictable landscape, a realm where they felt more at home. Over her shoulder, Rory carried a woven satchel containing the
solitary
possessions she might need on this journey: a canteen of water, some dried rations, the Fae-forged blade Isolde had gifted her, and the mysterious Heartstone pendant. Rory's eyes adjusted to the dim light as she followed Nyx along a narrow path, her
footsteps
crunching on a carpet of fallen leaves. The air felt heavy, scented with wildflowers and the musty decay of autumn. A soft glow emanated from the surrounding vegetation, bioluminescent flora that thrived in this realm where sunlight rarely penetrated. They passed a patch of fiery orange mushrooms sprouting from the base of an ancient tree. "Touch nothing," Nyx cautioned. "Many plants here are
otherworldly
, their essences akin to poison for mortal bodies." Rory nodded, her fingers twitching with the urge to pluck one of the
luminous
mushrooms. The warning only served to heighten her fascination with this mysterious place. She
sensed that every
step took her deeper into unknown territory, a world untouched by the conventions of her familiar Earth. As they ventured further, the trees thinned, revealing a small clearing encircled by towering ferns. A gentle mist clung to the ground, swirling around their ankles in phantasmal wisps. In the center of the clearing stood a small cottage constructed from braided willow branches and woven vines. An oval window glowed
softly
, emitting a warm, inviting radiance. "Isolde's home," Nyx said, their voice carrying the slightest hint of reverence. Rory felt a surge of awe and unease. A half-fae seer, old beyond reckoning, lived here in reclusion. The cottage seemed like a living part of the forest, organic in its construction, yet no ordinary treehouse or earthwork. It was a monument to the mystical powers that pulsed beneath the Veil. A rustling came from the ferns, making Rory jump. Nyx turned toward the noise, their shadowed form blending with the darkness. "It is only a rabbit," they assured, their voice calm and controlled. Rory blinked and saw the blur of a small animal, its eyes
glinting
in the fading light, before it darted away into the shadows. She sucked in a breath, aware that even the fauna in this realm was unlike anything she had ever encountered. Her perspective was changing with every new discovery, each a reminder that the scope of her world extended far beyond what she had known in Cardiff or London. The cottage's door swung open without a sound. A delicate figure stood in the threshold, framed by the warm, flickering light of countless candles. Isolde Varga was an
ethereal
vision, her long silver hair
cascading
down her back, pale skin glowing with an inner radiance. She held a wooden bowl filled with wild berries in one hand, offering it to them. Rory's steps faltered. Nyx guided her forward, sensing her hesitation. "Greetings, Seer," they said, their voice like the susurration of leaves on a still night. Isolde tilted her head, her pale lavender eyes locking on Rory. "Greetings, Nyx, and welcome," her voice carrying the lilting accent of distant lands. "You bring one of their kind, a seeker. She carries a gift from the demon lands." Rory's
eyes widened
as she realized Isolde referred to the Heartstone pendant. How could the Seer possibly know this? Nyx had said Isolde could not lie due to her Fae compulsion, yet she kept secrets like a locked chest. Nyx beckoned Rory closer. "It is custom to bring an offering to the Seer, especially one as insightful as Isolde." Rory's hand went to the satchel, a flutter of nervousness filling her. "I haven't much to offer," she confessed in a hushed voice. "I'm merely a delivery girl and a wanderer of the streets. My pockets are usually empty." "Yet you have the riches of worlds," Isolde said, her voice carrying a hint of riddle. "A stone from Dymas, a blade from the Fae Courts, and the power of humanity's ingenuity." Rory's fingers brushed against the curved handle of the Fae-forged blade, its cold touch seeping into her veins. "How do you know all this?" she blurted, unable to hold back the question. Isolde stepped back, a smile playing on her lips. "I know because I see, little one. Take a berry. Their sweetness will fortify you for the coming journey." Rory hesitated, taking in the plate of fruits, none of which she recognized. Eventually, she chose a deep blue berry and popped it into her mouth. An explosion of flavors burst across her tongue, an
intricate
symphony
of tastes she couldn't
begin to
identify. "Ah, you chose well. Our land's bounty is a
testament
to its secrets." Isolde gestured toward the small table and chairs that occupied the center of the cottage. "Please, sit. Share in my humble supper. The darkness deepens too
quickly
for mortals to wander safely." As Rory ate the
otherworldly
food and drank the honeyed mead Isolde offered, the Seer shared tales and prophecies filled with cryptic references to demons, Helbound souls, and the power of the Veil. In turn, Rory shared stories of her escape from Wales, her life in London, and the strange occurrences surrounding the Heartstone pendant. "The stone was a gift left in a mysterious package," Rory said, her fingers closing around the pendant. "It pulses warmer and brighter every time I'm near a portal or someone who's world-touched. I've no idea why it was given to me or who sent it." Isolde's
eyes widened
. "You have been marked. There are forces at play beyond your reckoning, forces that call upon you. Their whispers
echo
through the Veil. Your path leads deeper into the shadowlands, into Dymas." Rory's
blood ran cold
. When Nyx had mentioned the Unbidden Rift, a tear between Earth and Hel, she'd imagined a place of magic and mystery. But now, she wondered if it held something more dangerous—perhaps something
sinister
. Isolde's finger traced the edge of her wooden bowl, her eyes distant. "That which was given can also be taken. Your heart's desire will lead you onward, but beware. Dymas is the realm of gluttony, where excesses rule and senses become warped." Nyx's shadow shifted across the cottage wall. "Her journey is about to begin, Seer. The frost moon rises. The portal swells with power." Isolde gave a small nod, her expression
unreadable
. "Then the time is now. Venture into the Unbidden Rift, Aurora Carter. Seek that which you desire most. But remember, the Shadow and the Seer can only guide you. In Dymas, you must decide your own path." Rory's breath quickened at the mention of her desire. What did she wish for most? Family? Love? Vengeance? All options carried equal
weight
. Yet in the next moment, she knew her answer. She would venture into Dymas, face the unknown, and let her heart be her guide. As the pale moon rose over the Fae grove, Aurora Carter stepped through the Unbidden Rift, her resolve strong. She had no map to the realm of Gluttony, no guide save for the
enigmatic
Nyx and the cryptic words of Isolde. But she had to discover why she had
been chosen
, and what role she played in this unfolding tale of the mortal and magical realms.
