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.

A sliver of rippling air hovered between two columns of vine-choked marble. Aurora pressed a hand to her chest, where the Heartstone’s deep crimson glow pulsed through the silver chain. She inhaled, tasting the tang of grapes on the breeze, and stepped forward. The world shivered, then bloomed into a sky the color of molten amber, low and swollen as if about to break. She felt the Veil thin here, threads of reality fraying at the edges, and each heartbeat sent warmth radiating along her collarbone. Beneath her boots, the floor was smooth stone inlaid with pale quartz veins that glowed faintly underfoot. Gnarled roots twisted through the seams, sprouting black fruit the size of her fist. She knelt and unwound a ribbon of lichen from one branch; its surface glimmered with shifting lights, as though a hundred embers swirled behind its skin. When she touched it, a low hum thrummed up her fingers—an echo of something alive, hungry. Nyx drifted beside her, a silhouette of living shadow that flickered between solid form and mist. Their faint violet eyes glowed as they watched the orchard beyond. Aurora felt a chill in their presence—in Nyx lay the echo of the realms between realms, and here those boundaries sagged. A soft whisper brushed her ear: the Shade’s voice, carried on a wind that carried no scent. “We are not alone,” it breathed, and the hum in the lichen thrummed harder. Isolde followed, her silver hair brushing the vine-wrapped pillars. The Seer’s pale lavender eyes scanned the carvings: endless feasting scenes, faces locked in rapture and despair, plates piled so high they spilled from the tables in frozen cascades. She spoke in a voice like wind through chimes: “A feast eternal, yet every guest starves. What fills the bowl will empty the soul.” Indigo petals drifted from her hair as she moved, landing on the stone without leaving a mark. Aurora rose, pressing thumb to her scar—an anchor to the mortal world. She retrieved the Fae-forged blade, its moonsilver surface cold as winter moonlight. In the amber glow of the sky, the dagger gleamed pale blue. She sheathed it at her belt. Every ward in this place was carved of hunger; every doorway, a mouth waiting to swallow. She could taste the latent magic on her tongue, bitter as spilled wine. They advanced into the orchard’s heart. Grape clusters hanging heavy as lanterns glowed from within, each grape a perfect orb of crimson juice. Overhead, branches arched like ribcages. The air grew thick with the scent of sweet rot. A hush pressed in around them, broken only by the soft thrum of unseen wings. Shadows slithered through the bushes—long, twisting shapes that melted if stared at too long. Aurora’s breath caught. She knelt and tore a single grape free. It popped on her tongue, releasing syrup that tasted of memories not her own: the clink of goblets, laughter that turned to screams, the snap of bones. She tried to spit it out, but the flavor clung to her senses, singing of excess and loss. A line of ivory chairs appeared between the trees, each seat occupied by a phantom figure draped in feast-stained robes. They raised goblets of molten glass and drank, but as the liquid passed their lips it turned to ash. A tremor rippled through the ground. The phantom diners shuttered, their bodies cracking like porcelain. Aurora stumbled backward. Isolde’s voice murmured, “Beware the price of indulgence—it demands its due.” The shadow at Aurora’s flank stretched and recoiled; Nyx’s form solidified, arm outstretched. A wisp of darkness darted toward the phantom table, dissolving it into a swirl of motes that vanished. Beyond the clearing, a colonnade of vines parted to reveal a hall hewn from living bone. The arches curved like rib bones overhead, nail-like pillars sunk into the flesh of the earth, roots hanging like sinew. The scent of roasting flesh and burning sugar hung so heavy Aurora thought she might suffocate. She drew in a ragged breath and touched the Heartstone; it pulsed bright, a beacon guiding her steps. Inside, long tables stretched into shadow, each laden with impossible dishes. Oxen the size of wolves, glazed in molten honey, stood between platters of writhing serpents coiled in cinnamon sauce. Platters of golden pastries sent wisps of steam curling toward the bone arches. George, a chef of wrought-iron mask and crimson robes, materialized at the far end, wielding a carving knife that dripped molten fat. He inclined his head as if greeting old friends, but his eyes were empty hollows. Aurora swallowed. She stepped forward and rattled the Fae blade at her side. George paused, the knife raised in a silent salute. Isolde drifted beside Aurora, quiet as a breeze, her eyes fixed on the demon-chef’s mask. Nyx wove into the corners of the hall, merging with the gloom, scenting weak points in the wards. Without warning, the chef swept his blade in a slow arc. The shadows behind Aurora unspooled, and Nyx’s voice cut through the hush, a sudden gust in a silent room. Aurora dropped to one knee as the blade sliced overhead, carving a line of shattered bone dust across the floor. She sprang up, letting the momentum carry her toward the nearest table. She placed the flat of her dagger against the wood, and the moonsilver blade glowed, slicing through enchantments that clung like cobwebs. A hiss rasped through the hall. The roasted ox shivered, flesh rippling like living muscle. It shook free of its spit and lunged, jaws clamping around empty air. Aurora leapt aside, heart hammering, and drove the Fae blade between its ribs. The creature stilled, then dissolved into a shower of crimson petals that rained onto the bone tiles. Isolde crouched by a column, tracing braided runes carved in marrow-white stone. Her voice was a soft incantation. The runes flickered, shifting into a doorway of shimmering distortion. Through it, Aurora glimpsed a courtyard of black vines and silver leaves under a sky molten-amber dusk. There, a fountain of honey-bright liquid bubbled at the center, its basin carved with the face of Prince Belphegor, eyes empty yet forever watching. Aurora stepped toward the portal, heart thudding with equal parts dread and exhilaration. The Heartstone flared so bright she cracked both eyes open against its glow. She felt the pulse of Dymas in her veins, a tide of insatiable hunger that threatened to drown her in longing. She swallowed hard, pressing her hand to the Fae blade’s hilt. Beside her, Nyx’s form rippled with anticipation, and Isolde’s pale features set in quiet determination. She crossed the threshold. The air shifted, sweet to the point of cloying, and she tasted the lingering echo of the roasted ox, the serpents in sauce, the crackle of ember and bone. A line of black marble benches circled the fountain, each cusp carved with a sinning soul’s face, eyes turned upward as if begging for a draught of the honey fountain’s endless offering. The liquid lapped against its stone edge with a sound like laughter. Aurora swallowed. The world felt unnaturally close: the bones of the courtyard shining white under the amber sky, the waxen black vines curled around pillars, the knotted roots that pulsed as though alive. She met Isolde’s gaze and inclined her head. No words were needed. Nyx drifted through the shadows to stand guard. For a heartbeat, they simply stood in wonder and unease, three mortal souls on the rim of Dymas’s endless feast. The fountain’s honey-yellow surface rippled, and somewhere in the distance, a low, ravenous growl echoed—a reminder that here, indulgence was never innocent, and every gift demanded its price. Aurora touched the Heartstone one last time. It pulsed in answer, a beacon of warmth amid the hunger, and she stepped forward to learn just how deep the gluttonous realm’s appetite truly ran.
