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.

A character is alone in a strange, isolated place at night. They came here for a reason, but something feels off from the moment they arrive. The wrongness builds slowly — sounds that shouldn't be there, things that move at the edge of vision, a growing certainty that they are not alone. Build tension through restraint, not through gore. Use the codex entries above as your world reference for the character and setting. Only include the prose of the scene without any markdown or commentary.

The standing stones marked the edge of Richmond Park the way a scar marks skin—old, deliberate, impossible to ignore once you noticed it. Rory had walked past them a hundred times on her delivery runs, cutting through the park to save ten minutes on the bike, and never once had they looked like this. Not looming. Not *aware*. She checked her phone. No signal, which wasn't unusual this deep in the park, but the time stamp read 11:47 and she was fairly sure she'd left her flat above Silas's bar closer to ten. The gap didn't sit right in her stomach. She put the phone away and touched the Heartstone pendant at her collarbone instead, the way she'd taken to doing when she was nervous, though she couldn't have said when that habit started. The note had said midnight. It hadn't said where exactly, only *the grove, the old stones, come alone*—unsigned, slipped under her door in handwriting she didn't recognize, and she'd told herself all the sensible things a person tells themselves before doing something stupid. That it was probably Eva playing a joke. That she was a grown woman who could turn around any time she liked. That curiosity had never once gotten anyone into real trouble. She stepped between the oaks. The temperature dropped—not sharply, but enough that gooseflesh rose along her arms before her brain caught up and told her it was just the wind. Except there was no wind. The leaves above her hung motionless, black cutouts against a sky gone the wrong color, more purple than navy, like a bruise healing. Wildflowers grew underfoot even though it was October, small white things she didn't have a name for, closed up tight as fists. She'd been in this grove before, in daylight, delivering a package to someone who'd insisted on meeting her at the tree line rather than a real address. It had seemed charming then. Whimsical. Now the flowers looked like something waiting to open. "Hello?" Her voice didn't carry the way it should. It went out three feet and stopped, swallowed by the dark. She walked further in, boots silent on ground that should have crackled with fallen leaves and twigs, and that silence was the first thing that truly frightened her—not a big fright, not yet, just a small cold seed of it planted somewhere behind her sternum. She was making noise. She could feel the impact of each step travel up through her shins. But the grove gave nothing back. The pendant warmed against her skin. She stopped walking and looked down at it, at the deep crimson stone glowing faintly beneath her jacket, and told herself it was static, body heat, anything but what she suspected—that somewhere near here, something had opened that shouldn't be open. She'd learned, in the months since the pendant found her, that it didn't lie about that. Something moved at the edge of her vision. She turned fast, expecting a fox, a deer, a person—anything with a shape she could name—but there was only the dark mass of a hawthorn tree, its branches perfectly still. She stared at it for a ten-count, willing it to prove itself harmless by staying exactly as it was, and it did, and she almost laughed at herself, almost, except her heart was going too hard for laughter and her mouth had gone dry as chalk. "This is stupid," she said aloud, mostly to hear a human voice, even her own. "This is so stupid, Rory." The grove didn't answer. Of course it didn't. But the quality of the silence changed, subtly, the way a room changes when someone else walks into it, and she had the sudden, complete conviction that she was being listened to. Not watched—listened to. As if her voice were the interesting part, the thing worth attending. She made herself keep walking toward the center of the clearing, where the old stones stood in their loose circle, their surfaces black and wet-looking though it hadn't rained. Her plan, if she'd had one, had been to wait there. Whoever left the note would come to her. That had felt like a reasonable plan back in her kitchen with the lights on and Eva's half-empty wine glass on the counter. It felt like a very different plan now. A twig snapped behind her. She spun, and this time there was nothing at all to blame it on, no hawthorn, no shadow that could be reasonably mistaken for anything. Just the dark between two oaks, and the stones, and the flowers curled tight against the cold. "I know you're there," she said, and hated how thin it sounded. Nothing answered. But something shifted the air, a pressure change like a door opening in another room, and the flowers nearest her feet unfurled all at once—white petals peeling back in the space of a breath, far too fast, far too synchronized, and beneath the flowers the ground seemed, for one impossible second, to *breathe.* She backed away from it without deciding to. Her hand found the pendant and closed around it and the crimson stone was hot now, properly hot, hot enough that she should have dropped it and didn't. The whisper, when it came, didn't come from any single direction. It moved through the clearing the way cold moves through a house, finding every gap. *Aurora.* Not Rory. Not the name Eva used, or her mother, or anyone who actually knew her. The full weight of it, the christened shape of the word, said by something that had never once needed to be introduced. She didn't run. She wanted to, every muscle in her legs screaming for it, but some old cold-headed part of her—the part Eva always said would get her killed one day by refusing to panic at the correct moment—held her still and made her look instead of flee, made her actually see the shape gathering itself at the far edge of the stones, tall and wrong and not yet finished becoming whatever it intended to be. The pendant burned white-hot against her palm. And Rory, very quietly, began to understand that whoever had left that note had not been human at all.
