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.

</codex>

Write a fully fleshed out scene of at least 1000 words in the horror genre.

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.

Model response

The moss-soft ground swallowed Aurora's footsteps as she moved deeper into Richmond Park's shadowed heart. Her breath clouded in the crisp autumn air, each exhalation a momentary ghost against the darkness. The standing stones loomed ahead—ancient oak sentinels marking something older than memory.

She touched the Heartstone pendant at her throat, its deep crimson surface catching what little moonlight filtered through the dense canopy. The silver chain felt cold against her skin. Something had drawn her here tonight—a message from Eva, cryptic and urgent. Something about a portal. Something about danger.

The stones were larger than she remembered. Weathered surfaces etched with symbols that seemed to shift when she wasn't looking directly at them. Rory—always pragmatic, always analytical—felt the hair rise on the back of her neck.

Silence pressed against her ears. No night sounds. No rustling leaves. No distant urban hum from London. Just stillness.

Then: a whisper. So faint she might have imagined it.

Her hand instinctively went to her left wrist, fingers tracing the small crescent-shaped scar from childhood. An old nervous habit. Something her therapist had called a grounding technique.

The whisper came again. Closer.

Not words. Not language. Just... sound. Like fabric dragging across stone. Like breath without lungs.

Aurora Carter did not spook easily. She had survived an abusive relationship. She had navigated London's chaotic streets. She worked delivery shifts that took her through rough neighborhoods. But this—this was different.

The standing stones no longer looked like stones.

They looked like waiting figures.

Watching.
