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 yanked the collar of her bomber jacket higher, as if that small adjustment could mask the ragged rhythm of her breath against the cold. The streetlamp flickered out behind her like a candle snuffed by unseen fingers, plunging the approach to Richmond Park into abrupt darkness. She pulled her phone from her pocket—no signal. Of course there wasn’t. Richmond Park at night was already a black hole of coverage. She tapped the flashlight icon. The beam stuttered to life, weak and yellow, cutting a narrow tunnel through the mist that coiled over the pavement like lazy smoke. She didn’t want to be here. But Eva had left that voicemail at 3 a.m.—*Rory, come find me. It’s urgent. The Grove. They’re taking more people.*—and now her voice carried the ghost of static, as if recorded through a crack in the world itself. Eva didn’t just beg for help. She called with certainty, like someone who already knew the coordinates of a buried thing. Aurora’s boots scuffed fallen leaves as she stepped off the path. The air thickened. Not just cold—dense. Like wading through chilled syrup. The light from her phone dimmed further, the battery icon flirting with the red line. She shoved it back into her pocket, ignoring the ache of a twinge in her wrist—old scar from a playground swing gone wrong, long before Evan’s temper got its hooks into her. That scar throbbed now, not from pain, but from knowing. From the sense that something in the dark was turning toward her. She reached the boundary stones—four gnarled oaks, their trunks wrapped in ivy that pulsed faintly, as though breathing. Moss glistened like wet moss doesn’t, too bright, too new. She touched the bark. It didn’t feel like wood. It felt like living skin, warm and slick. Aurora pulled back her hand. The print of her fingers remained, imprinted in the green pulse. She swallowed. Her pulse pendant—the Heartstone—rested cool against her sternum, drilled into the silence. Eva had given it to her weeks ago, wrapped in brown paper, no note. *Wear it. Trust the pull.* The stone hadn’t moved since. Until now. Beneath her shirt, it began to hum, a low, resonant thrum like a tuning fork struck once in the deep. She lowered the collar. There was a light ahead. Not the sickly glow of her dying phone—purer. Whiter. It flickered between the trees like a candle in a distant window. Except there were no windows here. Aurora followed. The hum in her chest sharpened. The moon, when it occurred to her to look, hung bloated and yellow, not white. Its edge looked chewed, irregular. She blinked. The moon steadied—smooth again. But the wrongness lingered. Her breathing grew shallow. The trees leaned in, branches like outstretched hands. The light ahead steadied into a circle, a perfect ring of birch saplings arranged in a perfect circumference. Inside the ring, the grass glowed faintly, as if dusted with phosphorescent pollen. And at the center: Eva. She stood motionless, arms at her sides, face illuminated from below by that unnatural light. Her eyes were open. Too open. Shadows pooled in the hollows of her cheeks like liquid mercury. Aurora’s breath hitched. “Eva?” No response. She stepped forward. The ring of birches whispered against her sleeves. The sound wasn’t wind. It was words, fragmented and reversed: *...ties not held... flesh... sleep...* Eva’s head turned. Not all at once—like a marionette jerked by invisible strings. First chin up, then a slow lurch of the jaw, then the eyes slid left. She looked at Aurora with something that wasn’t Eva. Her lips were blue. Her pupils were blown wide, swallowing the iris. “Rory,” she whispered. Her voice cracked like ice. “You’re late.” Aurora’s fingers closed around the pendant through her shirt. It burned now. Not warm—hot. Like a coal pressed against flesh. She didn’t take it out. “What happened?” Aurora asked, stepping closer. Eva’s head tilted in the other direction, unnaturally far. “They came through the mouth,” she said. “In the trees. Not the ones here. The ones across. They’re hollow inside. Like teeth.” Aurora’s pulse spiked. “Who?” “The ones who shake the bones,” Eva whispered. Her mouth stretched too wide when she said it. “They like the sound of your spine when it breaks.” Aurora’s legs went weak. She wanted to run. But Ava didn’t move. She couldn’t. Her muscles weren’t hers anymore. Something giggled from the trees. Not like a child. Like wet, overlapping chuckles, skittering up and down a scale of rotting keys. Eva’s fingers twitched. Then curled into claws. Black fluid welled between her knuckles. Aurora yelped and stumbled back. The birch ring constricted around Eva like a noose tightening. Eva’s laugh bubbled out, thick and wet. “You brought the stone,” she said. “They want it. They always want the stone.” Aurora’s hand flew to the clasp behind her neck. The pendant pulsed once, twice—a heartbeat that wasn’t hers. She pulled it free. Light erupted from the Heartstone—deep crimson fire that seared the air. The trees shrieked. Bark split vertically, like lips peeling back from gums. Black sap oozed down the trunks. The glowing ring of birches collapsed inward, collapsing Eva with it. Eva’s body convulsed, limbs jerking as if pulled by invisible wires. Her mouth stretched wider, wider, cracking at the corners. A scream tore out—not hers. Something inside her was screaming *away*. The trees pulsed. The earth pitched. Aurora fell to her knees, the pendant burning in her palm. Eva’s ribs began to twist—slow at first, then faster, like gears in a broken clock. Aurora could see outlines beneath the skin—thin, white bones bending, reforming, elongating. The ribs arched upward, breaking through the skin in silent shrieks. Flesh peeled back like curtains. Aurora gagged. The pendant’s glow coruscated across the clearing, painting the scene in bloodlight. Shadows detached from tree trunks, now solid and shifting—limbs, torsos, faces not meant to be seen. One of them stepped forward from the dark. Tall, emaciated, wrapped in a cloak that looked like woven shadows. Its face was a shifting mask—sometimes smooth, sometimes split down the middle with too many eyes. It smiled. Its teeth were needles. “Little thief,” it said. Its voice was layered hymns sung backward. “You carry our name in your blood. You heard the music. You *hungered*.” Aurora’s arm trembled. She didn’t know what it was talking about. She didn’t know what hunger it meant. The thing tilted its head. “Or does it speak in your bones? Always hungry, blood-kin.” Aurora didn’t hesitate. She hurled the pendant at the ground. The moment the stone left her grasp, the clearing convulsed. The shadows recoiled like rats from a torch. The trees shuddered, bark falling away in great flakes. Eva collapsed inward, shrinking, her screams collapsing into a tiny giggle. Then silence. The pendant hit the earth. The crimson glow flared—once, twice—then guttered out. Aurora lay panting on the damp leaves. Her hand was empty. The scar on her wrist burned like a brand. Something wet splashed onto her cheek. She looked up. The moon was still wrong. The stars blinked in and out like faulty bulbs. And above her, suspended in the air, hung Eva—entire. But not Eva. Her face was smooth, featureless, like wax. Her eyes were closed. Her mouth wasn’t there at all. She drifted down. Slowly. Gently. Until she rested in a crumpled heap on the ground where she’d stood moments before. Aurora reached out. Eva’s hand was cold. *Too* cold. Aurora sat up. Her phone buzzed in her pocket. She pulled it out. The screen lit up—full battery. Full signal. Time: 2:17 a.m. She checked the call log. No missed calls. No voicemails. Her thumb hovered over the flashlight app. She wanted to see what was in the trees. What was *still* in the trees. But she turned it off first. Then she tucked the pendant back under her shirt. And she walked home through the wrong night without looking back.
