System
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 oak standing stones rose out of the bracken like the ribs of some long-dead giant, and Aurora stopped walking the moment she saw them. "This is it," she said. "It has to be." Behind her, Eva's torch beam wobbled across the moss-furred bark. "Rory, it's a park. People walk their dogs here." But her voice had gone thin, and she'd stopped chewing the gum she'd been worrying since they'd left the car park forty minutes ago. Aurora didn't answer. She was looking at the air between the stones — the way it shivered, faintly, like heat off summer tarmac, though it was the second week of November and her breath hung in clouds. To her right, where the dark should have been thickest beneath the trees, the dark instead seemed to lean toward the gap, to pour itself in that direction. That dark detached from the tree line and resolved into a shape roughly the height of a man. "You can see it," Nyx said. Their voice arrived the way it always did, not from a mouth but from everywhere at once, a whisper threaded through the branches. Two points of violet light hovered where eyes would be. "Most mortals can't. The boundary doesn't want to be noticed." "My eyes have been doing strange things lately." Aurora's hand drifted to her collarbone, to the small weight hanging there beneath her jumper. The Heartstone hadn't pulsed since they'd entered the park — this wasn't a Hel portal — but it felt warmer than her skin, the way a held hand stays warm. "Then go through. The Seer is expecting you." A pause, the violet eyes dimming a fraction. "I cannot follow past the threshold. The Fae do not love my kind. Shadows linger in their courts only on sufferance, and I am no longer welcome." "Comforting," Eva muttered. Aurora reached out. The shimmer between the stones resisted for a heartbeat — a faint, cool pressure, like pressing a palm against the surface of a pond from beneath — and then it gave, and her hand vanished to the wrist into nothing she could name. She stepped through. The cold left her at once. That was the first thing — the November bite, the damp seeping through her boots, gone between one footfall and the next, replaced by warm air that smelled of crushed green things and honey. She heard Eva swear softly somewhere behind and beside her, the words arriving slightly out of order, as though sound itself had to learn a new way to travel here. Then she opened her eyes properly and forgot to breathe. The clearing should not have fit inside the scrubby copse they'd been standing in. It rolled away in every direction, far wider than the trees outside could have held, ringed by oaks so vast and old that three people couldn't have linked arms around a single trunk. Light came from no sun she could find. It came instead from the grass, which glowed a soft silver-green underfoot, and from the flowers — and there were flowers everywhere, impossibly, in defiance of the season: foxgloves taller than Eva, bluebells the color of deep water, blooms she had no names for that turned their faces toward her as she passed, slow as sunflowers, slow as something watching. "Rory." Eva had grabbed a fistful of her sleeve. "Rory, look at the sky." She looked up. There were stars, but they were wrong — too many, too close, wheeling in slow spirals like leaves caught in a drain, and among them drifted things that might have been clouds or might have been continents, vast and luminous and very far away. While she watched, one of them pulsed gently, and she felt the pulse answer somewhere in her chest, in the small crescent scar on her wrist that had begun, faintly, to itch. "Don't look too long," she heard herself say. "I don't think it's good for us." They walked. The grass made no sound under Aurora's boots, swallowing her footsteps whole, and when she glanced back she saw that her trail had already smoothed itself away — no bent stems, no crushed flowers, nothing to say she'd been there at all. Eva left footprints. Aurora, for some reason she didn't want to examine, did not. The dagger at her hip had grown cold. Not the ordinary cold of metal, but a deep, aching chill that pressed through the leather sheath into her thigh. Isolde's gift, Nyx had called it, when the blade had arrived on her doorstep with no note three days ago — moonsilver, leaf-shaped, faintly glowing now in this sourceless light. A weapon of the very Courts she was walking into. She wondered if that was a courtesy or a warning. "How long do you think it's been?" Eva whispered. "Outside, I mean." "I don't know." That was the truth. Time moved strangely here; she'd read that much in the brittle pages Nyx had shown her. An hour inside could be minutes in the park, or days. She thought of her mother's voicemails, unanswered on her phone, and pushed the thought down. "Don't think about it. Just keep close." A sound reached them then — water, the silver chatter of a stream — and beneath it, something that lifted the hair on Aurora's arms: music. Not from instruments. Voices, maybe, or wind through the long grass, a melody with no beginning that wound around them and seemed to know them, to coax. Eva drifted half a step toward it, her face gone slack and dreaming. "Eva." Aurora caught her wrist. "Eva. With me." Her friend blinked, shuddered, came back into her eyes. "Sorry. Sorry. I don't know what—" "It's the grove. It wants us to wander off." She didn't know how she knew that. She knew it the way she'd known about the standing stones, the way the Heartstone had begun, lately, to teach her things she had no business knowing. "We follow the water. We don't follow the song." They crested a low rise where the wildflowers thinned, and there, in a hollow beneath the largest oak of all, a figure waited beside a pool so still it held the wrong stars perfectly, like a window into a different sky. She was seated on a stone with her silver hair pooling around her in the grass, and she was looking up at them already, pale lavender eyes catching the glow, as though she had been watching them approach since long before they arrived — perhaps, Aurora thought with a lurch, since long before they were born. "You came through the boundary leaving no mark," the woman said. Her voice was low, amused, terrible. "Most who enter trample everything they touch. But you, little delivery girl, you walk like one of mine." A smile, slow as the turning flowers. "How very interesting. Sit. We have so little time, and so much of it to spend."
