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 a sound like a wet cloth being wrung dry, and the air that replaced it tasted of overripe fruit and something darker underneath — burnt caramel, or charred honey. Rory swallowed hard and tried not to think about what she'd just walked through. The sky was wrong. That was the first thing. Not the colour, though the colour was wrong too — a deep, saturated amber that pressed down on everything like the last hour before a storm, except there was no sun to speak of, only a sourceless warmth that fell evenly across the land in every direction. It was the texture of the sky that unsettled her. It moved. Slowly, like fat cooling in a pan, vast slow-churning shapes rolling through the amber in shades of rust and gold. "Don't look up too long." Nyx drifted to her left, their silhouette breaking apart at the edges where the strange amber light caught them, shadows bleeding outward before pulling back in. Their violet eyes floated in the dark like two distant flames. "Why?" "The sky here is not sky." Rory looked back down. The land in front of them rolled outward in low hills threaded with vines so heavy with fruit the branches had bent into arches, creating tunnels of purple and black clusters that dripped slow amber juice onto the soil below. The soil itself was a deep red-brown, almost the colour of dried blood, and impossibly fine — it rose in small, lazy clouds when Rory shifted her weight from one foot to the other. Across the nearest hill, an orchard spread in rows so precise they might have been measured. Trees she had no name for, with pale bark and leaves the colour of old copper, hung with fruits that ranged in size from a fist to a human head. Some had split open on their own, bursting with flesh that caught the amber glow and gleamed. Everything here was full. Overfull. The Heartstone pendant pressed against her sternum, warm through the fabric of her shirt — not the gentle pulse she'd felt near the London portal, but a deep, rhythmic heat, like something far below her feet was breathing. Isolde stood a half-step behind, her silver hair unmoved despite the faint current that stirred the vine leaves around them. Her lavender eyes moved across the landscape with something that wasn't quite calm and wasn't quite recognition. "You've been here before." Rory watched the seer's face. "Haven't you." "I have seen this place." Isolde tilted her head, the way she always did when she was arranging her words into something technically true. "Seeing a fire and standing inside one are not the same wound." Nyx moved ahead without waiting, their feet making no sound on the red soil. "We follow the river. There will be a river." "You're certain?" Their silhouette turned slightly. "There is always a river in Dymas. It does not carry water." Rory fell into step behind them and did not ask what it carried. The vine tunnels swallowed them after thirty paces, and the amber sky disappeared above a lattice of interlocking branches. In the dimmer light beneath the vines, everything had a different quality — the fruit clusters hung close enough to brush her shoulders, and each time one grazed her jacket she caught a smell: roasting meat, baking bread, something sweet and animal she couldn't identify. Not unpleasant. That was what bothered her. She was, she realised, hungry, and she hadn't been a moment ago. She kept her hands at her sides. Isolde caught her arm softly. "Do not eat." "I wasn't going to." "You were considering it." Not unkind. Just exact. The tunnel opened onto a terrace of flat stone overlooking a valley below, and there was the river Nyx had promised. It ran dark and slow through the valley floor, the colour of black treacle, and it caught the amber light in long, oily reflections. Along both banks, figures moved with the unhurried deliberateness of people at work — carrying crates, operating long-armed devices Rory couldn't categorise at distance, tending enormous open hearths where something vast and indeterminate roasted on spits. They were people. Or they had been. She could see that in the shapes of them, the proportions, the way they walked and bent and turned. But they moved with something missing — the small inefficiencies of people with their own thoughts, the pauses and gestures that had nothing to do with the task at hand. These ones moved clean. Every action served the next. "Contracted souls." Nyx's voice was barely a breath. "Bound here. Their labour feeds the feasts." Rory stared at the nearest figure, a man or what had been one, stirring something in an iron vessel the size of a bathtub. His face, when it briefly turned upward, was placid. Not peaceful. Placid. There was a difference. "How long?" "Until whatever they agreed to expires." A pause. "Most agreements are poorly read before signing." Below, a bell rang — a low, resonant sound that she felt in her back teeth more than heard — and every figure along the riverbank stopped simultaneously, turned, and walked in the same direction with the unhurried precision of tide water. The fires kept burning. The spits kept turning. "We should move before the bell rings again." Isolde stepped back from the terrace edge. "The second bell calls the overseers." "What happens when the overseers come?" The seer folded her hands. "They count what is present. What should not be present draws considerable attention." Rory looked once more at the valley, at the dark river and the pale fires and the rows of human shapes that had forgotten they were human, and then she turned and followed Nyx back into the vines. The Heartstone burned against her chest all the way down.
