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 Veil gave way like wet silk. Rory felt it first in her teeth, a low hum that traveled up her jaw, and then the winter dark of the Thames-side alley was gone and something warm pressed against her face. She stumbled. A hand of cold smoke closed around her elbow and steadied her. "Breathe slowly," Nyx whispered, the voice a draft through a keyhole. "The first breath is the one that tells you what the place wants." She breathed. Woodsmoke, browned butter, split figs, and beneath them something darker and sweeter, like wine left too long in the sun. Her stomach clenched with a hunger so sudden and total that she nearly dropped to her knees. "Oh, that's not fair," she said. "No," said Isolde, stepping through the shimmer behind them. "It rarely is." The Half-Fae woman's silver hair lifted in a breeze Rory couldn't feel. She looked no more at home here than a swan in a butcher's shop, and yet she moved without hesitation, her bare feet crossing a path of pale gravel. Rory looked back at the stones. Her own boots had left crisp prints. Nyx's shadow-feet left a faint smear, like breath on glass. Isolde's left nothing at all. Rory straightened and looked up, and forgot about the hunger for a moment. The sky was amber. It wasn't sunset or a trick of smog. It was the deep, honeyed color of a lit lamp seen through whisky, and it glowed evenly from horizon to horizon without any sun to account for it. Below it the land fell away in terraces, and every terrace was alive. Vineyards ran in green-black rows, the grapes so swollen and dark they looked ready to burst. Orchards came after them, trees bent double under fruit Rory had no names for: gold spheres veined in red, long purple pods that dripped something clear, clusters of tiny white globes that chimed faintly against each other in the wind. Between the orchards lay gardens in ordered, geometric bloom, with herbs she half recognized grown to the size of shrubs. Against her sternum, the Heartstone pulsed. She pressed her palm over it through her jacket. The pendant was warm, warmer than her skin, throbbing in slow time like a second heartbeat. Whoever had pressed it into her hands, and she still couldn't say who, had known exactly where it would lead her. "It knows this place," she murmured. "It was made here," Nyx said. Their violet eyes drifted across the terraces, and the shadow of their body rippled strangely, thinner at the edges than Rory had ever seen it. The amber light had nowhere to pool, no dark corner to hide in. "I remember sorcerers who would have sold their own names for a glimpse of these gardens. I never thought to see them from the inside." "Are you all right?" "I am *exposed*, Aurora. It's a new sensation. I'm not certain I like it." They followed the gravel path down. The sound reached them slowly at first, a murmur under the wind, and then it swelled into clatter and shouting, the ring of copper, a knife's rapid tattoo on a board. Around a bend in the hillside the terraces opened onto a great amphitheater carved from the rock itself, and Rory stopped. It was a kitchen, or a thousand kitchens. Tiered stone counters climbed the slope in rings, and at each one a cook worked over flame or steam or something that shimmered and had no name. Whole roasted creatures turned on spits. Sugar was pulled into threads fine as hair and spun into shapes that hung in the air like frozen music. A woman in a stained white coat flipped a pan, and the contents rose in a perfect, glittering arc and came down on a plate that had been moved to meet it without anyone touching it. Rory had spent two years hauling paper bags of sweet-and-sour up staircases for Yu-Fei Cheung. She knew the look of good cooks under pressure. These had it, the focus, the flush, the forearms scarred in a dozen places. But she knew something else as well, and it took her a moment to place what was wrong. Nobody was smiling. "Look at their eyes," she said quietly. They were clear and bright and utterly fixed. The cooks did not glance up as the visitors passed. One man tasted a sauce from a wooden spoon, and something flickered across his face, a flash of ecstasy so raw it was almost grief. Then he wiped the spoon and began again, and Rory understood he had tasted it a thousand times and would go on tasting it. "Helbound," Isolde said softly. "Contracted from your world, some of them centuries ago. They asked for mastery, and they were given it." She tilted her head, her lavender eyes half closed. "The prince is a generous host. He never asked when they would be allowed to stop." "That's a riddle," Rory said. "Tell me it's a riddle." "I cannot lie, child. I only choose which truths to hold up to the light." Rory swallowed. Her mouth was watering, and she hated it. Somewhere close a smell rose that was exactly her mother's Sunday lamb, rosemary and crackling fat and the steam from potatoes, though she had not smelled it in six years. She turned toward it before she knew she'd moved. The cold on her wrist stopped her. She looked down. Her hand had drifted to her belt, where the Fae blade lay sheathed. The moonsilver hilt had turned her fingers numb, a bright clean ache that cut through the fog in her head like a slap. Isolde's gift. She drew it a few inches, and the leaf-shaped steel gave off a faint pearly light, though there was no moon in this amber sky. The smell of lamb dissolved. Underneath was only sugar and smoke. "Clever," Nyx whispered, close at her shoulder. "It doesn't just cut wards. It cuts *wanting*." "Then I'm keeping it out." She let the blade clear the scabbard entirely and held it low along her thigh. Her thumb rubbed the little crescent scar on her wrist, an old habit when she was thinking. "Which way?" Isolde lifted one pale hand and pointed past the amphitheater, where the path narrowed between two walls of espaliered pear trees. Their fruit hung in perfect rows, each pear polished and faintly luminous. As Rory passed, she saw that every one of them held a reflection, a tiny distorted face pressed against the inside of the skin. She did not stop to look closer. The path sloped down into a hush. The clamor of the kitchens faded behind them, and the amber light thickened, syrupy and slow. Nyx grew steadier here, the edges of their silhouette sharpening as the pears cast long shadows across the gravel. Rory noticed that they were walking in those shadows on purpose. At the end of the corridor stood a doorway with no wall around it, a tall arch of pale stone rising from the middle of the garden. Through it Rory saw the same garden, the same amber sky. But the Heartstone had gone from warm to hot, throbbing so hard she could feel it in her ribs, and the air inside the arch rippled like a heat haze over tarmac. "A portal," she said. "That's what it's been reacting to." "One of several," said Isolde. "The Wardens will not have counted this one. It's too well fed." Rory laughed, a short sound with no humor in it, and the stones swallowed it. Somewhere far behind them a great gong sounded, low and rolling, and every bird in the orchard fell silent at once. "That," Nyx breathed, "would be a feast beginning." "Or someone noticing we've arrived," Rory said. She tightened her grip on the cold, bright blade, tucked the burning pendant back beneath her collar, and stepped forward into the shadow of the arch, the others close behind her.
