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 path through Richmond Park at night was never quiet, but this was different. The usual murmur of distant traffic had faded to a dull hum, swallowed by the heavy press of the woods. Aurora adjusted the strap of her delivery bag, her boots crunching on frozen grass that shouldn’t have been frozen in March. The cold bit through her thin jacket, but she barely felt it. The Heartstone pendant burned against her collarbone, a dull thud beneath her shirt like the kick of a muted drum. She should have been home by now. Silas would be serving last orders above the bar, and her flat above it was warm, at least. Instead, she stood at the edge of the copse, staring into the dark where the standing stones waited. She hadn’t intended to come. Not tonight. Not like this. It had started in the kitchen of the Golden Empress, steam curling from a pot of noodles, Yu-Fei’s voice sharp over the clatter of woks. “You’re distracted, Carter.” “I’m fine.” “You keep touching your scar.” Her fingers had dropped from her wrist then, as if burned. She’d forgotten about the crescent mark on her left wrist—the old childhood burn from touching a stove too young, too curious. But there was something else tonight. A pull. A second heartbeat in her chest, thrumming through her veins, syncopated with the glow of the pendant. She’d told no one. Not Eva. Not even Silas. She’d clocked out, ignored the rain slanting across Borough High Street, and walked until she stood at the park’s northern edge, where the trees grew too close, too still. And now she was here. The grove wasn’t empty. She knew because the air changed before she saw anything. The usual scent of damp earth and pine sharpened into something metallic—like blood and iron. Her breath came too fast. She told herself it was the cold. Step in. The command settled in her bones before her mind could resist. The Heartstone pulsed once, deep crimson bleeding through the fabric of her shirt. She reached under her collar and touched the gem—smooth, warm, throbbing like a second pulse. She stepped forward. The moment her foot crossed the invisible threshold, the world stilled. Not silence—never silence. There was a sound, a low, wet *sclick* from somewhere in the darkness to her left. Like something wet being dragged across stone. She froze. No birds. No rustle of leaves. No distant car engines, no sirens, no human noise at all. Only that sound again—a slow, dragging scrape, followed by a wet *cluck*. Aurora exhaled through her nose. *Fox. Badger. Something natural.* She moved deeper. The wildflowers lining the path—white and purple and blue—all stood upright, defying gravity, their petals glistening as if latex-coated. They didn’t sway. They didn’t tremble. They simply *waited*. Their scent rolled over her—sweet, cloying, like overripe fruit left in sun. She wanted to gag but clamped her jaw shut. Her pendant glowed faintly, a ember behind her ribs. She kept walking. The standing stones rose ahead, four great oaks twisted into archways, their trunks grown together centuries ago, their bark blackened with age and something else—something like soot, but not quite. The stones stood in a rough circle, the center clear. That’s where she was heading. As she stepped into the circle, the ground beneath her sneakers turned spongy. Not moss. Not soil. Something softer. Organic. She looked down. The grass had turned dark, almost purple, and was pulsing slightly, like breathing. She pulled her foot up—wet, sticky. She didn’t want to know what it was. A whisper slithered through the air. Not words. Not in any tongue. A hissing breath, spoken from inside her own skull, from behind her eyes. *Rory.* She spun. No one there. Only the stones. Only the flowers. Only the wet, rhythmic pulse beneath her feet. She swallowed. “Hello?” Her voice cracked. No answer. But the whispering grew louder, layered now, a dozen voices overlapping, whispering in unison: *Stay. Stay. Stay.* Aurora forced herself to breathe. “Right. Okay. Plan change.” She reached for her phone—dead battery. Of course. Service never worked in here. She cursed under her breath. She needed to leave. But which way? The path back—the one she’d come through—was gone. Not overgrown. Not hidden. *Gone.* Where the dark trees had been, there was only a wall of vines, thick as ropes, pulsing slowly, like veins. She took a step toward them. The vines *twitched*. A slow, rhythmic contraction, as if something inside was breathing. She stumbled back. “Not possible,” she muttered. But everything was possible here. That was the point of the Fae Grove—the pocket between worlds, time moving like a drunk man’s waltz. Her pendant burned now, a searing heat against her sternum. She pulled it free. The deep crimson gem pulsed strongly, its glow cutting through the dark like a wound in the fabric of night. Something *answered*. From the center of the standing stones, the air rippled. Not like heat. Like water. The ripple advanced, and where it passed, the grass blackened further, the flowers withered into gray husks, the air thickened into syrup. And then— A sound. Not from outside. *From inside.* A soft, wet clicking, like teeth chattering, coming from her own throat. Aurora clapped a hand over her mouth. Her lips moved. She wasn’t saying anything. But her lungs were heaving, her diaphragm spasming. *No. No no no.* She dropped to her knees. The ground was cold, wet, unnatural. She pressed her palm to it. Her fingers sank in slightly, like into warm dough. The clicking grew louder. She tore her hand away. The earth clung to her skin, black tendrils clinging like wet hair. She wiped her hand on her jeans, scraping hard, but the filth wouldn’t come off. The whispering returned, louder now, more insistent. Words forming in the hiss: *We see you. We hear you. You are ours.* Aurora’s breath came in ragged gasps. She forced herself to stand. She had to think. She was smart. She was Rory Carter—cool-headed, quick-thinking. She had faced Evan’s fists and didn’t break. She had run from Cardiff to London and built a life. She’d survived. She needed a way out. The Heartstone. It had been given to her. By whom? She didn’t know. But it reacted to Hel portals. Maybe it could open one. Maybe that’s why she was here. She held the pendant high. The gem flared crimson, a sudden burst of light that illuminated the grove in a bloody glow. The standing stones groaned—actual sound, low and resonant, like a cathedral organ note vibrating in her teeth. The whispering stopped. Silence. Then, from the edges of the grove, figures emerged. Too tall. Too thin. Their limbs jointed wrong—elbows bending the other way, knees cracking like dry wood. Their skin was gray, stretched taut over irregular bones, fingers too long, tapering into blackened nails like claws. They moved without walking—more like sliding, their feet never quite touching the ground. Aurora’s blood turned to ice. They were Fae. Not the noble kind from stories. Not the Seelie Court with their golden hair and courtly manners. These were the Unseelie. The hungry ones. The ones who stole children and left changelings in their place. And they were all looking at her. One stepped forward, its face a smooth oval of gray skin, eyes black and depthless like voids. It tilted its head—too far, too long—and spoke in a voice like crushed velvet and rotten teeth. “Little thief,” it said. “You wear the Heartstone. You trespass in the grove. You carry the scent of the dying land.” Aurora’s voice returned in a croak. “I—I didn’t know.” “*Did not know.*” The Fae mimicked her, voice dripping with mockery. “As if ignorance excuses theft.” She backed up. Her calves hit one of the standing stones. Cold seeped through her jeans. The Fae began to circle. She held up the Heartstone, the gem pulsing wildly now, veins of crimson light racing through it like blood through a vein. “Stay back.” The lead Fae laughed—a sound like breaking glass. “The stone is broken. The portal bleeds. You cannot leave. And neither can we.” Aurora’s mind raced. The pendant pulsed stronger. She focused on it. *Calm. Control.* She thought of Eva. Of Silas. Of the flat above the bar, warm and safe and human. She had to get out. She pressed the pendant to her forehead. Light erupted. Not from the gem—from *inside* her. A pulse, a shockwave, a scream of violated physics. The Fae shrieked, their forms writhing like smoke in a storm. The standing stones split with cracks that raced upward like lightning, the sound deafening. Aurora threw herself forward, diving through the rift in the air where the stones had been. She tumbled onto damp earth. She was back in Richmond Park. The night was dark. Stars visible. No Fae. No glow. No wet, stinking earth. She lay there, gasping, her shirt torn, her hands caked in black filth. The pendant was dark. Cold. She sat up slowly. Her flat was two miles away. The streets were quiet. The cold bit at her again. She touched her wrist. The scar was there. The scar was *always* there. But the Heartstone— It was gone. Left behind in the grove. Or swallowed by the Fae. Aurora stood, her legs unsteady. She wiped her hands on her jeans again, but the stain remained. She started walking. Every step felt like a surrender. But she was still alive. And that, for now, was enough.
