You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The portal closed behind them with the sound of a door shutting underwater — muffled, pressurised, final. Rory stood still. Her lungs drew in a breath of something that was not quite air. It smelled of figs left too long in the sun, of wine soaked into old wood, of bread pulling apart in someone's hands. Rich and sweet and on the edge of rot. She pressed the back of her hand to her mouth and breathed through her nose until her stomach settled. "Move off the arrival point." Nyx drifted past her, their silhouette bleeding at the edges as it always did, never quite holding to one solid shape. "Portals in Dymas are monitored. Standing at one is worth about as much as knocking on a front door." She moved. The ground beneath her boots was soft — not grass, but something like it. Dense, dark-leaved growth pressed between flagstones of a deep terracotta red, and when Rory's foot caught the edge of a leaf it let out a faint, bruised smell. A perfume almost. She crouched and pressed two fingers to the leaf and it pulsed back, slow as a heartbeat. She stood up quickly. The sky was amber. Not a sunset amber — not that soft, transitional gold that London got sometimes in October just before the light gave up for the day — but a full, saturated amber as though the atmosphere itself had been steeped in something. Clouds moved through it like cream swirled in tea. There were two light sources she couldn't locate, throwing shadows in opposite directions, so that every object in her peripheral vision seemed to contradict itself. Nyx had already moved twenty feet ahead, their form sharpening and thinning in the strange double-light. "Stay close," they said, the words arriving at her ear with a slight delay, like an echo missing its source sound. "Dymas doesn't disorient the way Acheron does. It seduces. The difference matters." "What does that mean exactly?" "It means you'll want things. Old things. Things you thought you stopped wanting." Rory's hand moved without permission to the pendant at her throat. The Heartstone sat warm against her sternum — not the faint pulse it gave near portals, but a sustained, even heat, like holding a mug of tea. She let go of it. They walked a path that dropped gradually between two rows of vines. The vines themselves were wrong in a way she kept trying to pinpoint. The fruit that hung from them wasn't any single thing — clusters that began as grapes thickened partway through into something with the dark, waxy skin of a plum, and at the tip swelled into the shape and weight of small figs. All on the same stem. All ripe at once. Rory reached out and stopped herself an inch from touching one. The cluster swayed toward her hand, just slightly. "They do that," Nyx said. "They're plants." "They're Dymasian. It's not the same." Below the vines, the path curved and the canopy of a vast orchard opened ahead of them. Trees with silver-barked trunks spread wide enough that their branches met and locked together overhead, shutting out the amber sky, and beneath the interlocked branches hung lanterns of amber glass, no candles inside, just the glass themselves glowing. The light they gave was warmer still, and in it the fallen fruit on the ground glowed faintly at the edges — apples, pears, something Rory had no name for with skin the colour of a bruise and the heavy geometry of a pomegranate. The smell thickened. It was harder to breathe now, not for the density of the air but for how much the smell demanded of her attention. She was hungry. She hadn't been hungry ten minutes ago. "Don't eat anything." "I wasn't going to." "You were about to calculate whether you could," Nyx said. "I could see it." She kept her hands at her sides. They passed through the orchard and the path widened. From somewhere further in — deeper, lower, toward what felt like a centre of something — came sounds. Not voices yet, but the suggestion of voices: the wash of crowd noise, the scrape of furniture across stone, the ringing clatter of something metal on something metal. Rory stopped walking. At the base of a low hill to her left, sheltered under the spread of an enormous tree whose bark was the colour of charcoal, sat the remnants of a feast table. The table was the length of a bus. The plates were artworks — deep ceramic pools still stained with sauces of deep burgundy and dark green, towers of bones picked clean, glasses with dried rings of what might have been wine. Candles had burned entirely away, leaving only tall stalactites of wax. Garlands of the same impossible fruit draped between empty chairs. No one sat there. But the chairs hadn't been pushed back. They'd been pushed forward, like the people occupying them had simply descended through the seats. Rory moved closer without deciding to. The bones on the plates were large. Too large. Jointed in ways she recognised from no animal she could name, and pale not from bleaching but from age, from the kind of age that accrues over centuries rather than years. Between two plates sat a goblet still half-full, the dark liquid inside perfectly still. She bent over it. Her own reflection looked up at her but the angle was slightly wrong, as though her reflection sat deeper inside the goblet than the liquid level allowed. "Rory." She straightened. "There are souls contracted here," Nyx said from behind her, their voice lower than usual. "Chefs, servers. Bound to Belphegor's court. If any of them notice us —" A sound. Not from the direction of the feast noise below, but from the orchard behind them. A soft, rhythmic percussion of footsteps on the terracotta flags, unhurried, coming closer through the amber-lit trees. Nyx dissolved from solid to shadow in the span of a second, their form spreading across the ground. Rory's hand found the Fae blade at her hip — cold, always cold, even here in the warmth of Dymas — and closed around it without drawing it. The footsteps stopped.
