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 moon hung low over Richmond Park, casting a sil
very
glow that danced across the ancient oak standing stones marking the boundary of the Fae Grove. Aurora Carter, known to her friends as Rory, stood at the edge of the clearing, her breath visible in the crisp night air. She clutched the Heartstone Pendant, its deep crimson gemstone pulsing faintly against her palm, a subtle warmth that
seemed to
seep into her skin. The silver chain dangled between her fingers, catching the moonlight like a spider’s web. Rory had come to the Grove at the behest of a dream, a whisper of a memory that tugged at the edges of her consciousness. The dream had been vivid, a
tapestry
of colors and sounds that felt more real than the waking world. In it, she had seen the pendant glowing fiercely, a
beacon
in the darkness, leading her to this
very
spot. Now, standing alone in the clearing, she felt the
weight
of the night pressing in around her, the air thick with the scent of wildflowers that bloomed impossibly in the chill of autumn. The Grove was a place out of time, a hidden pocket between Earth and the Fae realm where the rules of reality bent and twisted. Rory had heard stories of people entering the Grove and emerging days later, though only minutes had passed outside its boundaries. She glanced at her
watch
, the hands ticking steadily, a comforting reminder of the world she knew. Yet, as she stepped forward, the
watch
seemed to
falter, the second hand stuttering as if caught in a loop.
A shiver ran down her spine
, and she paused, listening. The night was alive with the rustle of leaves, the distant call of an owl, and something else—a low, rhythmic thrum that
seemed to
emanate from the stones themselves. It was a sound that
resonated
in her bones, a primal
echo
that stirred a nameless fear within her. Rory shook her head, trying to dispel the unease that clung to her like a second skin. She had come here for answers, for a glimpse of the truth that lay hidden in the shadows of her past. The pendant was her guide, its faint glow a promise of revelation. She took a deep breath and moved deeper into the Grove, the grass whispering beneath her feet. The clearing was larger than it appeared from the outside, the trees arching overhead like cathedral spires, their branches entwined in a lattice of shadow and light. Rory felt the
weight
of their gaze, as if the
very
forest
watch
ed her progress with ancient, knowing eyes. She kept her focus on the pendant, its warmth a steadying presence against the chill that seeped into her bones. As she walked, the sounds of the night
seemed to
shift, the rustle of leaves becoming a susurrus of voices, indistinct and distant. Rory paused, straining to catch the words, but they slipped through her grasp like water through her fingers. She turned
slowly
, scanning the darkness for any sign of movement, but the Grove remained still, the shadows deep and impenetrable. A
flicker
of motion caught her eye, a brief flash of white at the edge of her vision. She spun around, heart pounding, but there was nothing there, only the trees standing silent and unmoving. Rory swallowed hard, her mouth dry, and forced herself to keep walking, each step a battle against the rising tide of fear. The pendant pulsed again, a gentle tug that drew her toward the center of the clearing. There, in a circle of moonlight, stood a single stone, taller and broader than the rest, its surface
etched
with runes that glowed faintly in the darkness. Rory approached it
cautiously
, her fingers brushing the cool, rough surface. The runes
seemed to
shift beneath her touch, rearranging themselves into patterns that defied comprehension. She closed her eyes, focusing on the warmth of the pendant, the steady rhythm of its pulse. The thrum of the stones grew louder, a heartbeat that matched her own, and she felt a strange sense of connection, as if the Grove itself recognized her presence. But beneath that connection lay something else, a shadow that lurked at the edges of her awareness. It was a presence, intangible yet undeniable, a sense of
being watched
by eyes that saw too much. Rory opened her eyes, her gaze sweeping the clearing, but the shadows remained still, the night holding its breath. A sudden gust of wind swept through the Grove, carrying with it the scent of damp earth and decay. The wildflowers shivered, their petals trembling in the breeze, and Rory felt a chill that had nothing to do with the temperature. The wind whispered through the trees, a voice that was not a voice, a sound that was not a sound, and she felt the hairs on the back of her neck stand on end. She took a step back, her instincts screaming at her to leave, to flee the Grove and the secrets it held. But the pendant pulsed insistently, a reminder of the dream that had brought her here, the promise of answers just out of reach. Rory hesitated, torn between the desire to know and the primal urge to run. The shadows shifted again, a ripple of movement that sent her heart racing. She turned, her eyes scanning the darkness, and caught a glimpse of something—a figure, pale and indistinct, standing at the edge of the clearing. It
was gone
in an instant, a trick of the light, but the sense of wrongness lingered, a
weight
that pressed down on her chest. Rory took a deep breath, forcing herself to remain calm, to think clearly. She had faced danger before, had learned to trust her instincts, but this was different. The Grove was a place of power, a realm where the rules of reality were fluid, and she was an intruder in its midst. The pendant pulsed again, a steady beat that matched the rhythm of her heart, and she felt a surge of determination. She had come too far to turn back now, to let fear dictate her actions. Rory squared her shoulders, her gaze fixed on the stone, and took a step forward. The ground beneath her feet
seemed to
shift, the earth soft and yielding, and she stumbled, catching herself against the stone. The runes flared brightly, a cascade of light that illuminated the clearing, and she felt a jolt of energy, a connection that thrummed through her veins. The shadows recoiled, the presence retreating, and Rory felt a moment of clarity, a sense of purpose that cut through the fear. She was not alone, not
truly
, and the Grove was not her enemy. It was a place of secrets, of hidden truths, and she was here to uncover them. The pendant glowed
warmly
, a
beacon
in the darkness, and Rory felt a sense of peace, a certainty that she was on the right path. The night was still, the air heavy with the scent of wildflowers, and she
knew that whatever
lay ahead, she would face it with courage and resolve. The Grove
watch
ed, silent and eternal, as she turned away from the stone, the path before her clear and unyielding. Rory walked into the shadows, the pendant a steady presence against her heart, and the night closed in around her, a shroud of mystery and wonder.
