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 standing stones rose out of the Richmond mist like teeth breaking through gum, black and slick despite the dry evening. Rory counted seven before she lost track, her boots sinking into moss that shouldn't have existed this late in October. "This wasn't here Tuesday," she said. "I ran this path Tuesday." Nyx flowed between two of the stones without touching them, their edges rippling like ink dropped in water. "The grove doesn't announce itself to joggers, Aurora." "Could've announced itself a little. Saved me the confusion." The air changed the moment she stepped past the threshold — thicker, sweeter, carrying the smell of crushed thyme and something underneath it that reminded her of rain on hot pavement. Behind her, the ordinary sounds of the park died away mid-note, a blackbird's call cut clean in half like someone had taken scissors to the world. "Nyx. The birds stopped." "They didn't stop. We left them behind." Rory turned. The path she'd walked in on curved away into ordinary trees, ordinary dusk, maybe thirty feet back. It looked close enough to touch. It looked like a photograph of somewhere she used to live. "That's not comforting." "I never said it would be." She kept walking because stopping felt worse. The wildflowers came up to her knees — poppies red as the Heartstone at her throat, bluebells that hadn't bloomed anywhere in England for months, white starflowers she didn't have a name for, their petals faintly luminous even without moonlight. When she brushed one with her fingers it chimed, actually chimed, a sound like a wine glass struck with a fork, and then the flower folded itself shut and refused to open again no matter how she coaxed it. "Guess it doesn't like being touched twice." "Very little in Fae territory does." The pendant at her chest gave a small pulse of warmth, unusual, since there was no portal here that she knew of — unless the boundary between grove and outside counted as one. She pressed her palm flat against it and it settled, quieting like something soothed. "It's doing that thing again." Nyx's violet eyes tracked the gem without turning their head, the whole gesture somehow more unsettling than if they'd simply looked. "The stone knows where it stands, even if you don't." "Cryptic. You're starting to sound like her." "I'll take that as an insult." The ground sloped downward, gentle at first, then steep enough that Rory had to grab at low branches to keep from sliding. The trees here didn't look like oak or ash or anything she recognized from home — bark silver-grey and smooth as bone, branches curling upward in spirals that caught what little light existed and threw it back in fractured colours, faint greens and golds swimming across the canopy like the inside of an oil slick. She heard water before she saw it, a stream running uphill against every rule gravity was supposed to enforce, pooling into a still black mirror at the bottom of the slope. "Tell me that's not going where I think it's going." "Water finds its own logic here. Best not to drink from it." "Wasn't planning to." She crouched at the edge anyway, curiosity winning over caution the way it always did, and found her own reflection staring back wrong — hair longer than she remembered cutting it, eyes a shade greener than blue. The reflection blinked half a second before she did. "Nyx." "Don't look too long." "I wasn't planning to do that either." She stood too fast, heart going harder than the moment warranted, and the reflection rippled apart into circles that took an age to settle. Somewhere above them a bird finally called, one note, high and strange, nothing like a blackbird — closer to a bell struck underwater. "How much further to her?" "Time doesn't move the way you're used to. We could be five minutes from her clearing or five hours. The grove decides." "Comforting." "You keep using that word wrong." "I keep meaning it wrong on purpose." The path — if it could be called that, more a suggestion of trodden grass between the flowers — wound between two more standing stones, closer together than the first ring, close enough that Rory had to turn sideways to fit through. The moment she cleared them the light changed entirely, gold now instead of silver-green, warm the way late afternoon in August felt warm, and the flowers here grew taller than her waist, heavy heads nodding though there was no wind to move them. "It's beautiful," she said, and hated how small her voice sounded saying it. "It wants you to think that." "You don't trust anything, do you." "I've had three hundred years of reasons not to." A shape moved between the stalks ahead, too quick to be Isolde, gone before Rory's eyes could fix on it — deer-shaped, or close to it, antlers wrong somehow, too many points, each one glowing faint blue at the tip like a struck match. She froze. Nyx's form solidified fully beside her, no longer flickering at the edges, solid enough to grip her arm if it came to that. "What was that?" "Something that belongs here. We don't." "Should I be worried?" "You should be careful. There's a difference, though I understand why you'd confuse them." The shape didn't return. The flowers settled. Somewhere far off, or not far at all, distance meant nothing here, a voice hummed a melody Rory almost recognized, something her mother used to sing washing dishes, except the words were wrong, ancient, syllables that scraped against her ear like they weren't meant for a human mouth. "That's her," Nyx said. "Or near enough." "How can you tell?" "Because nothing else in this place would bother making itself sound so much like home."
