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.

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 oak standing stones loomed against the moonless night, their rough surfaces etched with symbols older than memory. Aurora Carter's breath misted in the unexpectedly cold air of Richmond Park, the wildflowers around her unnaturally still despite the faintest whisper of wind. She'd come here looking for answers. The Heartstone pendant around her neck—a gift from someone she couldn't remember—pulsed with a warmth that felt more like a warning than comfort. Its crimson gemstone caught what little ambient light existed, casting strange reflections that seemed to move independently of her own shadow. The grove felt wrong. Not dangerous, precisely. Something more unsettling: a sense that the landscape was watching her, calculating. Listening. Rory's delivery shift at Golden Empress had ended hours ago. She should be in her flat above Silas' bar, nursing a cup of tea and scrolling through case files. Instead, something had drawn her here—a compulsion she couldn't fully explain, a nagging certainty that answers waited among these ancient stones. A sound. Not quite a rustle. Not quite a whisper. Her bright blue eyes darted left, then right. The wildflowers hadn't moved. Not a single petal trembled. But something had shifted. The standing stones seemed subtly closer than moments before, their lichen-covered surfaces no longer forming a perfect circle but a fractionally tighter ring. As if they were slowly, patiently closing around her. Her left hand—the one with the small crescent-shaped childhood scar—twitched involuntarily. Another sound. Softer this time. Like breathing. But not hers.
