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.

Frost furred the bracken in Richmond Park, and Aurora's breath hung in front of her like a second, slower ghost. Three hours past midnight. The deer had gone quiet an hour ago. Somewhere behind them, the last streetlamp on Sawyer's Hill Road buzzed and died in the distance. "Tell me we're close." Aurora shoved her hands deeper into her jacket pockets. The crescent scar on her left wrist itched, as it always did in the cold. Nyx drifted a pace ahead, more outline than body, a tall hole cut in the night. The violet of their eyes swept the treeline. "Closer than you'd like." The voice slid across her ear like dry leaves. "Look left. Not with your eyes. Look through them." She looked left. Nothing but a stand of oaks. Then she let her focus go slack, the way she did when she hunted for a house number in the rain, and the air between two of the trunks buckled. It rippled like heat over a road, only the night was freezing. "There." Her pulse ticked up. "That's the Veil?" "A thin place in it. The solstice is four nights off. It sags this time of year, like an old rope." Nyx raised one hand. The fingers thinned to smoke and threaded into the shimmer. "Cold on this side. Warm on the other. Follow close, Aurora. Do not stop to admire anything." "Admire anything?" Nyx didn't answer. They stepped through and the dark folded around them. Aurora followed. The pressure hit first, a soft squeeze against her eardrums, like surfacing from the deep end of a pool. Her ears popped. The frost bit at her ankles once more, then let go. She opened her eyes. The oaks were not trees. From the inside she saw that. They stood in a ring, twelve of them, each thick as a bus shelter and taller than any tree had a right to be, their bark gone silver and hard as granite. Spirals crawled up their trunks in shallow grooves, and something in the grooves moved. Slowly, patiently, a pale green light travelled along the carvings, climbing and dripping and climbing again. "They're stones," she whispered. "They're growing, but they're stones." "They are both. That is the joke of this place." Nyx stood beside her, solid now, their edges crisp as cut paper. "Mind the ground." She looked down. Wildflowers came up to her knees, foxglove and harebell, poppies the red of a stop light, and others she had no name for. A flower with petals like folded glass tilted toward her as she passed. Every one was in full bloom. December had not followed her through. She crouched and touched a poppy. Warm. It felt like touching a sleeping animal. "Did you see that?" She jerked her hand back. "See what?" "It breathed." "Yes." Nyx's violet gaze rested on her. "Everything here does." They walked. The path was not a path, only a place where the flowers had leaned aside, and it curved as though someone had drawn it with a lazy finger. Aurora glanced back once. The stone ring had already dimmed behind a curtain of hanging vines, each strung with drops of light that swelled and fell upward. "Upward," she muttered. "Right. Fine." Her phone hummed in her pocket. She fished it out. The screen showed 3:14, then 9:52, then 3:14 again, the numbers flickering like a broken sign. She thumbed the side button. The screen went black and stayed that way. "Nyx. My phone." "Will not tell you the hour. I would not trust any clock here." A ripple ran along Nyx's shoulders. "I entered a grove like this once. Aldric went in at breakfast. He came out to find his apprentice an old man." "Aldric?" "A man I used to know." The whisper thinned. "Walk." The air changed as they went deeper. Sweetness rose from the flowers, honey and crushed mint and something below them, a mineral tang like a coin on the tongue. A sound came up beneath it. At first Aurora took it for wind. It was too even for wind. It had a pulse, a low pattern of rises and falls, and when she stopped walking she realised it matched the rhythm of her own heart, then slid away from it and settled into a slower beat. The pendant against her breastbone gave a small, warm throb. She pulled the silver chain free of her collar. The crimson stone glowed from within, faint as a coal in ash. "That's not meant to do that." She turned it over in her palm. "It only warms up near a portal to Hel." Nyx bent close. The violet eyes narrowed to slits. "Then somewhere close, the Veil is wearing thin in more than one direction." "Great." Aurora tucked the stone back under her shirt. It kept pulsing against her skin, patient as a second heartbeat. "Love that. Love a bonus." The flowers thinned. Ahead, the ground fell away into a shallow bowl, and the bowl held a pool so still it looked poured from black glass. No stars showed above it, yet the surface held a whole sky of them, wheeling slowly, in colours no astronomer had ever catalogued. A blue-white one shed a thread of light that lengthened, snapped, and drifted down to become a moth. The moth alighted on Aurora's sleeve. Its wings were made of tiny text, curling script in a language she almost knew. "Don't touch it," Nyx murmured. "I wasn't going to." She held her arm out straight and breathed shallow. The moth crawled up to her cuff, fanned its wings once, and lifted away. Where it had rested, her jacket sleeve smelled of rain on hot tarmac, a smell she had loved since she was six. "How does it know that?" Her voice cracked. "It does not. You do." Nyx watched the moth go. "The grove hands back what you carry. Be careful what you carry." She swallowed. Evan's face slid across her mind, sharp and unwelcome, and the pool answered. A ripple crossed its surface and a shape rose in the reflection, a man's silhouette on a doorstep. Aurora's stomach clenched. Her fingers found the leaf-shaped dagger at her belt and closed on the hilt. Cold pulsed up her arm, clean and bright as a slap. The silhouette dissolved. The pool went smooth again. "Better," Nyx breathed. "Keep hold of that." "I'm holding it." Her knuckles had gone pale. She made her hand loosen a finger at a time. "Is she watching us? The Seer?" "Everything here watches. Whether it cares is another question." They skirted the pool. On its far side the standing oaks returned, smaller, huddled, and between them hung something Aurora took for washing on a line. She stepped nearer. Hundreds of ribbons, silk and cord and scraps of frayed cloth, dangled from the low branches. Each was knotted, and each knot held something small. A tooth. A brass key. A curl of red hair. A child's milk-white button. She brushed one with a fingertip. The ribbon shivered and whispered a sound like a name, too soft to catch. "Offerings," she said. "People leave them." "People did." Nyx lifted a ribbon gone grey with age, and it crumbled to lint in their grasp. "Some of these are older than London." Aurora reached up to a low knot near her face. It held a tiny bird skull, no bigger than a walnut, and the socket of one eye glinted violet in the glow. She turned to look at Nyx, and found the Shade gazing at the ribbons with an expression she had no words for, the silhouette of their face gone very still. "You've been here," she said. "No." The whisper barely stirred the air. "But I recognise the knots." A low chime rolled through the clearing, clear as a struck glass, and every ribbon swung the same direction at once.
