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 rift spat them out onto warm earth. Rory landed on her knees, palms sinking into soil so dark and rich it looked like ground coffee. For a moment she stayed there, breathing, waiting for her stomach to catch up with the rest of her. The crossing had felt like being pulled through a keyhole backwards. Behind her the air still rippled, a seam of shimmering distortion folding in on itself like a closing mouth, and then it was gone. "Up," Nyx whispered. Their voice came from everywhere and nowhere, a draught slipping under a door. "Slowly." She stood. Then she forgot, briefly, how to do anything else. The sky was amber. Not sunset orange, not the sodium glow of a London night, but a deep, honeyed gold that hung over everything like the inside of a glass of whisky held up to a lamp. There was no sun that she could find. The light simply *was*, soaking into the world from every direction at once, so that nothing cast a proper shadow. Nothing except Nyx. They stood beside her in solid form, a tall silhouette of living dark, and the light seemed to bend around them rather than touch them. Their violet eyes burned brighter here, sharper, as if the amber glow had turned up the contrast on everything unnatural. Rory noticed that the edges of their body kept fraying, tendrils of shadow drifting loose and snapping back like a flag in a wind she couldn't feel. "You all right?" she asked. "This place does not care for darkness." A pause. "It is tolerable." Isolde had not fallen. Of course she hadn't. The Seer stood a few paces off, silver hair spilling down to her waist, her pale lavender eyes fixed on the horizon with the calm of someone reading a menu she'd seen before. When she took a step forward, Rory watched the soil beneath her bare foot and saw it stay perfectly smooth. No print. No dent. As if the ground had simply declined to acknowledge her. "Dymas," Isolde said. "The table that is never cleared." "Is that a riddle, or are you just being poetic?" "Yes." Rory let it go and looked properly. They stood at the edge of a vineyard that ran downhill for what might have been miles, rows of vines marching in perfect lines toward a valley lost in golden haze. But these were not any vines she recognised. The trunks were thick as a man's thigh and twisted like wrung cloth, and the grapes hung in clusters the size of her head. Some were a deep, bruised purple. Others were translucent, glowing faintly from within, and inside each one she could see something moving, a slow swirl like smoke trapped in glass. She stepped closer. The nearest cluster was the colour of rose quartz. Up close it smelled of honey and cloves and something beneath that, something she couldn't name but that made her mouth flood with water so suddenly she had to swallow. Her hand was already halfway to it before she noticed. "Don't." Nyx's fingers closed around her wrist, cool and weightless as a breath of night air. Their thumb rested over the little crescent scar there, and she felt it the way you feel someone watching you. "Nothing here is only fruit." Rory pulled her hand back and flexed it. Her pulse was going faster than it should. Seven months driving deliveries for the Golden Empress and she'd thought she was immune to food smells. She'd carried Yu-Fei's crispy duck through the rain with her stomach growling and never once opened a bag. But that had been hunger. This was something else, something that reached past her stomach and took hold lower down, a tug like a hook set in soft flesh. "Noted," she said. Her voice came out steadier than she felt. Against her sternum, the Heartstone Pendant warmed. She'd grown used to its moods over the past weeks, the faint pulse of heat whenever they came near one of the rift points, the way it seemed to breathe against her skin. But this was different. The pendant wasn't pulsing. It was *humming*, a steady, contented warmth, like a cat settling into a patch of sun. She drew it out from under her collar. The crimson stone, no bigger than her thumbnail, glowed brighter than she'd ever seen it, its inner light matching the sky so perfectly that for a moment it looked like a drop of Dymas itself caught in silver. "It likes it here," she said quietly. Isolde turned her head. "Things always know the way home. Whether they wish to return is another matter." Rory tucked the pendant back beneath her shirt, but the warmth stayed with her, a small hot coin over her heart. They walked. The path between the vines was paved in flat stones worn smooth by centuries of feet, and in the cracks grew tiny white flowers that turned their faces to follow the three of them as they passed. Rory tried not to look at them too long. The air was thick and heavy, like the inside of a kitchen during a dinner rush, and it carried layers of scent that shifted every few steps: bread, then roasting meat, then something sharp and citrus, then a sweetness so dense it was almost syrup. Somewhere far off, she could hear music. Strings and something like a drum, a slow, rolling rhythm that she felt in her teeth. And beneath the music, very faintly, the sound of knives. Chopping. Hundreds of them, maybe thousands, a steady rain of steel on wood from somewhere down in the valley. It never stopped. It never even stuttered. "What is that?" she asked. Nyx's shadow rippled. "Kitchens." "That's a lot of kitchens." "It is a great many souls." She thought about that. She thought about contracts signed on Earth, about people who'd traded something for talent or fame or one more year, and where they might end up when the bill came due. She thought about the rhythm of the knives, how perfect it was. How tireless. The path crested a low rise, and the orchard began. The trees here were taller than any cathedral she'd seen, their bark silver-grey and smooth as skin, their branches heavy with fruit she had no names for. Some looked like pomegranates cut from garnet. Some were long and pale and curved like crescent moons. One tree bore nothing but small golden spheres that chimed softly against each other whenever the air moved, a sound like distant wind chimes, and beneath it the ground was littered with fallen ones that had split open to reveal centres of glittering black seed. Rory stopped under that tree and tipped her head back. Gold light filtered through the leaves, dappling her hands. It was beautiful. It was so beautiful that it frightened her a little, because she understood suddenly that this was what it was *for*. Every inch of this place had been built to make you stop, to make you look, to make you want. "Rory." Isolde had come up beside her without a sound. "Look lower." She did. At the base of the trunk, half-buried in fallen fruit, lay a small table set for one. White linen, stained at the edges. A silver plate. A goblet, tipped on its side, its contents long since dried to a dark crust. And a chair, pushed back, as though whoever had been sitting there had simply stood up mid-meal and walked away. Or been taken. "How long has that been here?" she asked. "Long enough that no one has thought to clear it," Isolde said. "Or long enough that someone wishes it to be seen." Nyx had gone very still. Their outline had sharpened, the loose tendrils drawn tight against their body, and when they spoke the whisper had an edge to it. "We are being watched." Rory didn't turn around. She let her hand drift to her hip, to the slender shape sheathed there, and when her fingers brushed the hilt of the Fae-Forged Blade, the cold of it bit into her skin like ice water. It was always cold. She'd stopped flinching at it weeks ago. But here, in all this syrupy heat, the chill felt like a lifeline, a single clean note cutting through the noise. The moonsilver didn't glow. There was no moon to wake it. "Where?" she murmured. "Everywhere," Nyx said. "The flowers. The fruit. This whole realm has eyes, and it has noticed that we have not eaten." Far below, in the golden haze of the valley, the chopping of the knives went on without pause. But the music had changed. The slow roll of the drums had quickened, just slightly, like a heartbeat picking up pace. Like something setting a table for guests. Rory drew a slow breath, tasted honey and smoke and iron on the back of her tongue, and started walking again. "Then let's not keep our host waiting," she said. "But nobody touches anything." Behind her, Isolde's laugh was soft as falling petals, and she left no footprints at all.
