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 didn't just smell of damp earth and rotting leaves; it tasted of crushed mint and ozone, a sharp, electric tang that coated Rory’s tongue. She stepped over the threshold of the ancient oak standing stones, expecting the familiar crunch of Richmond Park’s gravel paths, but her boot sank instead into a carpet of moss so thick it felt like walking on a living mattress. Behind her, the silhouette of Nyx rippled. The Shade didn’t walk so much as bleed forward, their form a jagged tear of midnight against the impossible amber glow of the clearing. Nyx’s violet eyes pulsed with a low, rhythmic light, scanning the shifting canopy. “The Veil is thin here,” Nyx whispered, the sound like dry leaves skittering across a tombstone. “It weeps. Can’t you feel the salt on the wind, little mortal?” Rory didn't answer. She was too busy staring at the wildflowers. They weren’t the stubborn, wind-whipped blossoms of a London spring. These were vast, bell-shaped blooms in colors that shouldn’t exist—shades of ultraviolet and iridescent copper that
seemed to
breathe, their petals curling and uncurling in a rhythm that matched Rory’s own heartbeat. She reached down, her fingers grazing the silver chain around her neck. The Heartstone Pendant, the thumbnail-sized crimson gem she’d carried since the night her life unspooled,
was beginning
to thrum. It wasn’t the frantic heat it gave off near a Hel portal, but a steady, insistent warmth, like a purring cat. "Don't touch the flora, Aurora," a voice drifted from the front of their small procession. Isolde Varga moved through the high grass with a grace that bordered on the offensive. The Half-Fae’s silver hair trailed behind her like a comet’s tail, catching the stagnant light. Rory watched Isolde’s feet; as the codex of her mind reminded her, the woman left no footprints. Not a single blade of grass bent beneath her
weight
. It was as if the world refused to acknowledge she was there at all. "The nectar of the Star-Bell is a slow poison for your kind," Isolde continued, her pale lavender eyes fixed on a point somewhere in the future. "It turns the blood to honey. You would sleep for a century and wake as a tree. A sturdy oak, perhaps, but quite useless for the task at hand." "Right. No touching. Standard procedure," Rory muttered, tucking her hands into her jacket pockets. Her thumb brushed against the small crescent scar on her left wrist, a nervous habit that grounded her when the world stopped making sense. They pushed deeper into the Grove. The geometry of the place
began to
fail. Trees didn't grow straight; they spiraled like corkscrews, their bark smooth and white as polished bone. High above, the sky wasn't the bruised purple of a London sunset but a
searing
, delicious amber, the color of Dymas. Rory felt a sudden, hollow ache in her stomach—a phantom hunger that made her mouth water. "Why does it look like the Gluttony realm?" Rory asked, her voice sounding thin in the heavy air. "I thought this was a Fae pocket." "It is a crossroads," Isolde said, pausing before a curtain of weeping willow branches that glowed with a faint, bioluminescent dew. "The Prince of Dymas has a long reach, and his gardens often bleed into the fringes of the Fae. Hunger is a bridge, Aurora. It connects all things that breathe." Nyx shifted, their form becoming more translucent, almost drifting into the shadows cast by the bone-white trees. "The Wardens would have a fit if they saw this rift. It’s a gaping wound." "The Wardens see what they are allowed to see," Isolde countered. She reached out and parted the willow branches. Rory gasped. Beyond the curtain lay a hollow that defied every law of physics she’d learned in Cardiff. A central pool of water sat suspended in the air, a perfect sphere of liquid silver hovering ten feet above the ground. Around it, the ground fell away into a spiraling staircase of floating stone platforms, each one covered in a different biome—one held a miniature forest of crystal ferns, another was a riot of golden wheat that swayed despite the lack of wind. The smell of woodsmoke and roasting meat hit Rory then, so potent it made her knees weak. It was an indulgence of the senses, a sensory overload that whispered of feasts and bottomless wine. Dymas. The influence of Belphegor’s realm was unmistakable here, mingling with the cold,
ethereal
beauty of the Fae. "This is where the vision ends and the work begins," Isolde said, turning to face them. In the amber light, she looked like a statue carved from moonlight. She reached into the folds of her gossamer robes and withdrew a slender, leaf-shaped dagger. The blade
was forged
of moonsilver, and even from several feet away, Rory could feel the chill radiating from it. It was a cold that didn't just bite the skin—it
seemed to
quiet the soul. Isolde held the weapon out, hilt-first. "Take it, Malphora." Rory flinched at the name. It was a name from an old life, or perhaps a future one, one she wasn't ready to claim. She stepped gingerly onto the first floating stone platform. It held firm, though the sensation of nothingness beneath her boots made her head spin. She reached out and took the Fae-Forged Blade. The moment her fingers closed around the hilt, the world snapped into a sharper focus. The shimmering distortion of the Veil, usually just a
flicker
at the corner of her eye, became a visible shroud, a translucent membrane separating this pocket from the mundane streets of Richmond just miles away. The dagger hummed in her hand, a low, vibrating note that neutralized the
oppressive
heat of the Dymasian amber sky. "It's freezing," Rory whispered, her breath hitching. "It is a piece of the winter solstice," Isolde said. "It will cut through the wards of those who serve the Prince of Excess. It will find the heart of a demon when steel would only melt." Nyx drifted closer, their violet eyes fixed on the blade with something approaching reverence—or fear. "A dangerous gift for a girl who still delivers noodles for a living." Rory looked at the Shade, then back at the blade. She thought of her flat above Silas’ bar, the grease-stained menus of the Golden Empress, and the suffocating memory of Evan’s hand on her arm. She thought of the way the Heartstone was currently pulsing against her chest, a warning of the darkness gathering at the edges of the world. She gripped the dagger tighter. "The noodles can wait," she said, her voice regaining its Cardiff steel. "What's the next move?" Isolde smiled, a thin, sharp expression that didn't reach her eyes. "We go down. Below the roots of the world, where the hunger starts." As they began their descent into the spiraling depths of the grove, the light changed. The amber deepened into a bruised crimson, and the sweet smell of the flowers turned to the heavy, cloying scent of overripe fruit. The silence of the grove
was replaced
by a low, rhythmic thumping, like a drum played underwater. Rory looked down at the crescent scar on her wrist. It
was glowing
faintly, reflecting the silver of the Fae blade. She wasn't just a delivery girl from Cardiff anymore; she was a witness to the breaking of the world. Each step took them further from the London she knew, descending into a landscape where the trees whispered secrets of ancient sins and the water flowed upward toward a sun that never set. Discovery turned to a cold, creeping unease. The beauty of the grove was a
facade
, a thin layer of gold leaf over something ancient and ravenous. But as Rory glanced back at the silver-haired seer and the living shadow at her side, she realized she wasn't afraid. She was curious. And in a realm built on gluttony, curiosity was the most dangerous hunger of all.
