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 standing stones rose out of the bracken like the ribs of something long dead, and Aurora stopped walking the instant she saw them. "Those weren't here a minute ago," she said. Beside her, Nyx flowed rather than stepped, their shadow-form bending around the low December light that slanted through the oaks of Richmond Park. "They were always here," the Shade answered, voice thin as a draft beneath a door. "We simply weren't allowed to see them." Seven of them, gray and lichen-furred, leaned inward to form a rough ring perhaps thirty feet across. Frost rimed the grass everywhere Aurora had walked — she'd left a trail of bruised silver behind her — but inside the ring of stones the ground was a different season entirely. Green. Impossibly, indecently green. She touched the Heartstone pendant at her throat out of habit. It lay cold and quiet against her sternum; whatever this place was, it was not a tear in the Veil. It was something older and stranger, a door that opened sideways. "We go in?" she asked. "You asked to find the Seer." Nyx tilted what passed for their head, the faint violet glow of their eyes guttering like candleflame. "The Seer is in. Therefore we go in." Aurora drew a breath of cold London air, the last of it — exhaust and wet leaves and the distant ghost of someone's bonfire — and stepped between two of the standing stones. The world changed the way a held note changes when a second voice joins it. The cold vanished. Not gradually, but all at once, as though she'd walked through a curtain into a heated room. Warmth bloomed across her face and forearms, and with it came scent: jasmine, crushed thyme, the heavy sweetness of blossoms she had no name for. The bare-armed oaks of the park were gone. In their place stood trees in full leaf, their canopies threaded with a light that had no obvious source — it didn't fall from above so much as hang in the air, gold and pollen-thick, settling on everything like dust. "Oh," she said softly, because there was nothing else to say. Wildflowers grew everywhere. Foxgloves taller than she was, their bells deep violet and faintly luminous; poppies the red of arterial blood; small white star-shaped things that turned, slowly and deliberately, to follow her as she passed. She was certain of it. She watched a cluster of them swivel on their stems to track her movement, and the back of her neck prickled. "They're looking at me," she whispered. "Everything here is looking at you." Nyx had gone more solid since they'd crossed the threshold — she could see the suggestion of a face now, planes of darkness arranged into something almost human, almost handsome. They seemed surprised by it, flexing a hand of woven shadow before their own eyes. "Interesting. The boundary is thin here. It pulls me toward shape." The ground beneath Aurora's boots was springy with moss, and it gave off the faintest light when she pressed it, a blue-green phosphorescence that faded the moment she lifted her foot. She glanced behind her. Her footprints glowed for three paces and then went dark. Nyx left none at all — but then, Nyx never did. The deeper they went, the louder the silence became. That was the only way she could think of it. There were sounds — birdsong, but slowed and stretched, each note bending into the next like something heard underwater; a trickle of water somewhere ahead; the dry whisper of leaves moving though she felt no wind at all. But beneath all of it lay a vast attentive quiet, the held breath of a place that knew it had visitors and was deciding what to make of them. "How long have we been walking?" she asked. Nyx was quiet a moment. "I do not know. That is the honest answer. Time runs crooked in places like this. An hour here might be a heartbeat out there." A pause. "Or a year. Watch your hunger. Watch your thirst. Eat nothing you are offered, however lovely. That is the oldest rule there is." The warning settled cold in her stomach, even as the path opened before them into a clearing, and Aurora forgot to be afraid. A pool lay at its center, perfectly round, perfectly still, mirroring a sky she did not recognize. The London afternoon she'd left behind had been flat and pewter-gray. The sky over the pool was deep amber shading to rose, threaded with two pale moons that hung close together like a pair of eyes. Around the water grew the standing stones again — or others like them — and from their crowns hung lanterns of woven branch and trapped firefly-light, swaying though still no wind moved. Aurora knelt at the pool's edge. Her own reflection looked back, black hair, blue eyes, the small crescent scar pale on her wrist where she braced herself on the moss. Then the reflection smiled, though her own mouth had not moved. She jerked back. "Nyx." "I saw." The Shade was at her shoulder, and there was an edge to their whisper now, a thinning of patience into wariness. "This grove tests. It shows you faces. Some of them are yours. Most of them are not. Do not bargain with the water." "I wasn't going to bargain with the water," Aurora said, with more steadiness than she felt. She stood, brushing damp from her knees, and that was when she noticed the flowers had stopped turning toward her. They had all turned, every bloom in the clearing, toward a gap in the far line of trees. Something was coming. No — someone was already there, had perhaps been there the entire time, standing so still between two oaks that Aurora's eye had slid right past her. Silver hair fell to the woman's waist, catching that sourceless gold light and throwing it back doubled. Her eyes were the pale lavender of the foxgloves. She wore no shoes, and where she stepped forward onto the glowing moss, the moss did not light, did not bend, did not mark her passing at all. "You came a long way," the woman said, and her voice was low and amused, "to ask a question you already know the shape of." Aurora's hand drifted to the cold weight at her hip — the leaf-bladed dagger, moonsilver, faintly luminescent now in the doubled moonlight. The woman's gaze followed the movement and her smile widened, soft and ancient. "You won't need that, child. Not here." A tilt of the silver head. "Not yet." "Isolde," Aurora said. "That is one of the things I am called." The Seer spread her empty hands. "Welcome to the Grove. Mind your hunger. Mind your tongue. And mind, most of all, what you choose to believe is a reflection." Behind Aurora, the still pool rippled once, though nothing had touched it.
