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 pendant lay cold against Rory's skin as she navigated the darkened paths of Richmond Park, her phone's flashlight casting elongated shadows across the leaf-strewn ground. She checked the map again, making sure she was headed toward the coordinates Eva had sent. Her breath plumed in the October air while the park's vastness stretched around her, empty save for the occasional rustle of nocturnal wildlife. "This is ridiculous," Rory muttered, pulling her jacket tighter. The text from Eva had been cryptic: *Found something about your pendant. Meet at these coordinates. Come alone. Midnight.* It wasn't like Eva to be so melodramatic, but then again, Rory had noticed her friend's increasing obsession with the Heartstone since she'd first shown it to her. The pendant had appeared on her windowsill three weeks ago, wrapped in parchment bearing only her true name—Aurora Carter—written in elegant script. She'd been reluctant to keep it, but something about the crimson stone had called to her. Since then, she'd experienced strange dreams and moments when the stone grew inexplicably warm against her skin. Rory checked her phone again. 11:52 PM. She was close. The trees grew denser as she walked, their canopies blocking what little moonlight filtered through the cloudy sky. Her flashlight beam seemed to dim, struggling against the thickening darkness. When she reached a circular arrangement of ancient oaks, Rory paused, consulting her phone one last time. This was the place. She pocketed her phone and swept her light across the clearing, but Eva was nowhere to be seen. "Eva?" she called, her voice sounding small against the enormity of the night. Something shifted in her peripheral vision—a flicker of movement that vanished when she turned toward it. Probably just shadows cast by her flashlight. She stepped forward, between two of the massive oaks that formed a natural archway. The air changed. It was subtle at first—a slight shift in pressure, a strange thickness to the atmosphere. Rory took another step, and the world around her seemed to ripple. The pendant against her chest pulsed with sudden warmth. The clearing beyond the oak sentinels was nothing like the Richmond Park she knew. Wildflowers carpeted the ground despite the late season, their colors muted in the darkness but still visible. The arrangement of trees formed a perfect circle, their ancient trunks twisted into unnatural shapes. Standing stones—or what she had initially thought were standing stones—revealed themselves as more ancient oaks, petrified into stone-like monoliths. "Eva?" she called again, her voice sounding different now—flatter, as if the air absorbed the sound before it could echo. Rory checked her phone for the time. 11:53 PM. But when she looked at the screen again seconds later, it read 12:17 AM. She blinked, tapping the screen in confusion. Her battery, which had been at 78%, now showed 42%. A hushed whisper drifted past her ear. Rory spun around, her heart thumping. "Hello? Eva, is that you?" The clearing remained empty, but Rory could no longer shake the feeling that she was being watched. The weight of unseen eyes pressed against her from all directions. She turned slowly, flashlight beam cutting through the darkness, illuminating nothing but flowers and trees. The pendant grew warmer, almost uncomfortable against her skin. Rory pulled it out from beneath her shirt, startled to find the crimson stone glowing with an inner light that pulsed like a heartbeat. Another whisper, this time from behind her. Words just beyond comprehension, spoken in a language that seemed familiar yet impossible to grasp. When she turned, the flowers where her light fell withered and blackened, only to bloom again when the beam moved past. Something was wrong with this place. Wrong with time. Wrong with reality itself. Rory took a step back toward the oak archway through which she'd entered, but it was no longer there—just an unbroken circle of ancient trees and stone-like monoliths. "This isn't funny," she said, her voice steady despite the fear building inside her chest. Years of facing down Evan's unpredictable rage had taught her to control her outward reactions, to appear calm when she was anything but. "Eva, if this is some kind of joke—" Movement flickered at the edge of the clearing—a shadow detaching from the deeper darkness between two trees. Rory's flashlight beam darted toward it, but whatever had been there was gone. The wind picked up, carrying with it the scent of wet earth and something else—something metallic and ancient. The flowers around her feet began to sway, not with the wind but in a synchronized pattern, like fingers tapping against the ground. Her phone chimed, making her jump. A text from Eva: *Where are you? I've been waiting at the park entrance for 20 minutes.* Confusion and dread mingled in Rory's stomach. If Eva was at the entrance, then who had she followed? What had led her here? She tried to call Eva, but the signal dropped immediately. The phone's clock now read 1:38 AM. "I need to leave," Rory said aloud, as if declaring her intention might make it possible. The pendant burned against her palm now, its glow illuminating her face in crimson light. The pulse of its inner radiance quickened, matching the frightened beating of her heart. Another movement caught her eye—closer this time. A figure, humanoid but wrong somehow, slipped between two of the oak monoliths. Rory's flashlight caught it for just a moment—tall, thin, with limbs that seemed too long for its body and skin the color of bark. "Who's there?" Rory demanded, her voice finally betraying a tremor of fear. A whisper answered, this time clear enough to understand: "*Malphora*." The name sent a jolt through Rory's body. It was a name she recognized and yet had never heard before—a name that belonged to her but had never been spoken aloud in her presence. The pendant's light flared brighter, and with it came a rush of memories that weren't her own: a realm of endless twilight, creatures of impossible beauty and terrible purpose, a war between courts, a princess in hiding. "I don't understand," Rory said, backing toward the center of the clearing as shapes began to emerge from between the trees—tall, graceful figures with eyes that reflected her flashlight's beam like those of animals caught in headlights. They moved with fluid, inhuman grace, never fully emerging from the shadows. Their whispers filled the air, a chorus of voices speaking that name again and again: "*Malphora, Malphora, Malphora.*" The small crescent scar on Rory's left wrist began to burn as if freshly cut. She clutched it with her right hand, feeling the raised tissue pulse beneath her fingers. It had never been from a childhood accident as she'd been told—that much became suddenly, terrifyingly clear. "What do you want from me?" she called out, turning in a slow circle as the figures drew closer, still keeping to the shadows at the edge of the clearing. The whispers changed, became a single voice that seemed to come from everywhere and nowhere: "*Remember who you are. Remember what you fled. Remember why you hide.*" The pendant's crimson light spread outward, enveloping Rory in a cocoon of scarlet radiance. The light touched the approaching figures, illuminating them fully for the first time. They were beautiful and terrible—tall, willowy beings with skin like polished wood and eyes filled with stars. Some had antlers that branched toward the sky; others wore crowns of thorns and ice. All looked at Rory with expressions of hunger and recognition. "I'm not who you think I am," Rory said, but even as the words left her mouth, she felt their falseness. The pendant's warmth spread through her body, awakening something that had slept inside her for twenty-five years. The leader of the figures stepped forward—a woman with hair like midnight and lips the color of crushed berries. When she spoke, her voice was the rustle of leaves and the crack of winter ice: "The veil grows thin, Malphora. Your glamour weakens. The courts have found you, and they come—both Seelie and Unseelie, both summer and winter. They come for what you stole." Rory's mind filled with impossible images—a throne room carved from a single massive tree, a ceremony of blood and starlight, a desperate flight through realms with something clutched to her chest. The Heartstone. Not a gift, but a theft. "I don't remember," Rory whispered, though fragments were returning now—shards of a life she had been made to forget. "You will," the woman said, extending a hand with fingers too long and joints too numerous. "Time moves differently in the Grove. What has been minutes for you has been centuries for us—centuries of searching, of waiting. But now you have returned, and the Heartstone with you." Rory clutched the pendant tighter, its light pulsing between her fingers. "I need to go home." A smile curved the woman's lips, revealing teeth sharp as thorns. "But dear child, you are home. The mortal realm was never yours. The life of Aurora Carter was never yours. You have worn a mask for so long, you've forgotten the face beneath it." The other figures began to close in, their movements liquid and predatory. Rory backed away until she bumped against one of the stone-like oaks. The pendant's heat had become unbearable, its light so bright it turned the night to crimson day. "Please," Rory said, though to whom she was pleading, she wasn't sure. "I just want to leave." The woman's smile widened. "The door behind you. It will take you back—for now. But we have found you, Malphora, and the Heartstone calls to its rightful place. You cannot run forever." Rory felt the trunk behind her shift and move. When she turned, there was an opening in the ancient oak—a doorway filled with darkness. Without hesitation, she plunged through it, the pendant's light guiding her way. The last thing she heard before the doorway sealed behind her was the woman's voice, carried on a wind that smelled of wildflowers and blood: "We will be waiting, Princess. The courts always collect their debts."
