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.

Aurora Carter stood at the edge of the Fae Grove, the ancient oak standing stones
looming
like silent
sentinels
in the moonlight.
The air was thick with
the scent of wildflowers, their vibrant colors muted in the silvery glow. She adjusted the strap of her messenger bag, the
weight
of the Heartstone Pendant resting heavily against her chest. The deep crimson gem pulsed faintly, a subtle warmth seeping through the fabric of her shirt. She had come here at Eva's insistence, a cryptic message urging her to find something important in the Grove. Rory had learned to trust Eva's instincts, even when they led her to places like this — places that felt like they existed just a step out of sync with the rest of the world. She took a deep breath, the cool night air filling her lungs, and stepped past the boundary marked by the standing stones. The moment she crossed into the clearing, the atmosphere shifted. The usual sounds of Richmond Park — the distant hum of traffic, the rustle of leaves in the breeze — faded away, replaced by an eerie stillness. Rory's
footsteps
seemed unnaturally loud on the soft grass, each step
echoing
in the silence. She glanced around, her bright blue eyes scanning the shadows that clung to the edges of the clearing. Something felt off. She couldn't quite put her finger on it, but the hairs on the back of her neck stood on end. She tightened her grip on the strap of her bag and pressed on, her eyes drawn to the center of the Grove where a faint,
otherworldly
light
shimmered
. As she approached, the light resolved into a small pool of water, its surface
perfectly
still and reflecting the moonlight like a mirror. Rory knelt beside it, her reflection staring back at her with an intensity that made her uneasy. She reached into her bag and pulled out the Heartstone Pendant, holding it up to the light. The gem's inner glow
seemed to
pulse in time with her heartbeat, casting a faint crimson hue over her face. She was about to lower the pendant when she heard it — a soft, almost imperceptible whisper. Rory froze, her breath catching in her throat. The whisper came again, a sibilant murmur that
seemed to
come from all around her. She turned
slowly
, her eyes darting to the shadows at the edge of the clearing. There was nothing there, just the dark shapes of trees and the faint outline of the standing stones. "Hello?" she called out, her voice sounding small and uncertain in the stillness. There was no response, just the whispering that
seemed to
grow louder, more insistent. Rory stood up, her heart pounding in her chest. She took a step back, her foot slipping on the damp grass. She caught herself, her eyes never leaving the shadows. Something moved at the edge of her vision, a
flicker
of motion that made her spin around. There was nothing there, just the empty clearing and the silent trees. She swallowed hard, her mouth dry. The whispering grew louder, a
cacophony
of voices that
seemed to
press in on her from all sides. Rory backed away from the pool, her eyes wide with fear. She clutched the Heartstone Pendant, its warmth a small comfort in the growing darkness. She had to get out of here, had to find Eva and figure out what
was going
on. She turned and
started to
run, her
footsteps
pounding against the grass. The whispering followed her, growing louder and more frantic. She glanced over her shoulder, her breath coming in ragged gasps. The shadows
seemed to
move, to reach out for her with dark, grasping fingers. She stumbled, her foot catching on a root, and fell to the ground. The pendant slipped from her grasp, landing with a soft thud in the grass. Rory scrambled to her feet, her eyes searching frantically for the pendant. She spotted it a few feet away, its crimson glow a
beacon
in the darkness. She lunged for it, her fingers closing around the cool metal of the chain. As she stood up, she felt a cold hand close around her wrist. She screamed, the sound
echoing
through the clearing. She spun around, her eyes wide with terror. There was no one there, just the empty clearing and the silent trees. She looked down at her wrist, the small crescent-shaped scar from her childhood accident standing out starkly against her pale skin. The cold sensation lingered, a phantom grip that made her shiver. Rory clutched the pendant to her chest and ran, her breath coming in short, panicked bursts. The whispering grew louder, a chorus of voices that
seemed to
come from everywhere and nowhere. She reached the edge of the clearing, the ancient oak standing stones
looming
ahead of her. She pushed through the boundary, the air around her seeming to shimmer and warp. As she crossed back into Richmond Park, the whispering stopped abruptly. The familiar sounds of the park returned, the distant hum of traffic and the rustle of leaves in the breeze. Rory stumbled to a halt, her chest heaving as she
tried to
catch her breath. She looked back at the Grove, the standing stones now just dark shapes against the night sky. She had to find Eva, had to figure out what
was happening
. She turned and started walking, her steps unsteady but determined. The Heartstone Pendant pulsed faintly against her chest, its warmth a reminder of the strange,
otherworldly
place she had just left. As she made her way through the park, the sense of wrongness lingered, a shadow that clung to her like a second skin. She couldn't shake the feeling that she was
being watched
, that something had followed her out of the Grove. She quickened her pace, her eyes scanning the darkness for any sign of movement. The night
seemed to
stretch on endlessly, the path ahead of her winding through the trees like a serpent. She kept moving, her mind racing with questions and fears. What had she seen in the Grove? What was the source of the whispering? And most importantly, what did Eva
know
about all of this? Rory's thoughts
were interrupted
by a sudden rustling in the bushes to her left. She froze, her heart pounding in her chest. She turned
slowly
, her eyes wide with fear. The bushes were still, the darkness impenetrable. She took a step back, her breath coming in short, panicked bursts. A figure emerged from the shadows, its form indistinct and shrouded in darkness. Rory's breath caught in her throat, her body tensing with fear. The figure moved closer, its features becoming clearer in the moonlight. It was a woman, her face pale and her eyes wide with terror. "Rory," the woman whispered, her voice trembling. "You have to get out of here. It's not safe." Rory's
eyes widened
in shock. "Eva?" she gasped, her voice barely a whisper. "What are you doing here?" Eva shook her head, her eyes darting around the darkness. "There's no time to explain. We have to go, now." Rory nodded, her mind racing with questions. She followed Eva, her steps quick and unsteady. The sense of wrongness grew stronger, a
palpable
presence that
seemed to
press in on her from all sides. She glanced over her shoulder, her heart pounding in her chest. The shadows
seemed to
move, to reach out for her with dark, grasping fingers. She quickened her pace, her breath coming in short, panicked bursts. She had to get out of here, had to find safety. She clutched the Heartstone Pendant to her chest, its warmth a small comfort in the growing darkness. As they made their way through the park, the sense of wrongness lingered, a shadow that clung to them like a second skin. Rory couldn't shake the feeling that they were

know
about all of this? As they reached the edge of the park, the sense of wrongness
began to
fade, the familiar sounds of the city returning. Rory took a deep breath, the cool night air filling her lungs. She looked at Eva, her eyes filled with questions. Eva shook her head, her expression grim. "We'll talk later," she said, her voice low. "For now, we need to get somewhere safe." Rory nodded, her mind racing with thoughts and fears. She followed Eva, her steps quick and determined. The Heartstone Pendant pulsed faintly against her chest, its warmth a reminder of the strange,
otherworldly
place they had just left. As they made their way through the city, the sense of wrongness lingered, a shadow that clung to them like a second skin. Rory couldn't shake the feeling that they were

Eva shook her head, her expression grim. "We'll talk later," she said, her voice low. "For now, we need to get some rest." Rory nodded, her mind racing with thoughts and fears. She followed Eva inside, the Heartstone Pendant pulsing faintly against her chest. The sense of wrongness lingered, a shadow that clung to her like a second skin. She couldn't shake the feeling that they were
being watched
, that something had followed them out of the Grove. As she lay in bed that night, the events of the evening replayed in her mind. The whispering, the shadows, the sense of
being watched
— it all felt like a nightmare she couldn't wake up from. She clutched the Heartstone Pendant to her chest, its warmth a small comfort in the darkness. Sleep came
slowly
, her mind filled with questions and fears. What had she seen in the Grove? What was the source of the whispering? And most importantly, what did Eva
know
about all of this? As she drifted off to sleep, the sense of wrongness lingered, a shadow that clung to her like a second skin. She couldn't shake the feeling that they were
being watched
, that something had followed them out of the Grove. The night stretched on endlessly, the darkness filled with whispers and shadows.
