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 streetlights in Richmond flickered as Aurora stepped off the pavement, her boots sinking into damp moss long before she reached the standing stones. The air smelled of wet earth and crushed pine. No fog tonight—just a heavy, breathless stillness that clung to her skin like dew. She hadn't expected to come. Not tonight. Not ever, really. But Eva’s voice had crackled through the speaker of her old phone two hours ago, raw and urgent: *"Rory, I think he found me. I saw something black move past my window. Not a shadow—like a stain parting the dark. You know what they say about Hel portals. They don’t open outward only. They also… leak."* Aurora had dropped the phone. Felt the cold press of the Heartstone pendant against her sternum, even through her leather jacket. It had started glowing again that morning—faint, rhythmic, like a heartbeat behind her ribs. She'd blamed stress. Too many late-night deliveries and too little sleep. But Eva was afraid. And Eva wasn’t one for imaginary stalkers. Aurora reached the outermost stone—a rough, weather-beaten oak monolith flecked with lichen. It was warm to the touch, humming faintly under her palm, though the night air was bitter. She pressed her forehead to the stone. A mistake. Images flashed behind her eyes: a woman with silver hair, kneeling in blood; a man in a suit of thorns dragging a chainsaw across wet grass; and something else, something with too many teeth, writhing between roots. She jerked back, gasping. The pendant burned against her chest—a sharp, sudden flare like someone had lit a match inside her shirt. She fumbled it out. The gem pulsed deep crimson, pulsing in time with her heartbeat, but faster. Irregular. *Like it’s counting down.* A twig snapped behind her. Aurora didn’t turn. Couldn’t move. She forced her eyes back to the grove. The standing stones stood in a perfect circle now, though she didn’t remember arranging them. The wildflowers around their bases had uncurled, their petals unfurling into grotesque grins—each daisy now had teeth. She swallowed. The air tasted like iron. Her breath fogged in front of her. Then stopped. *No.* She exhaled sharply. Condensation clouded in front of her again. But the cold was wrong—too thick, too slow, like breathing through syrup. Her fingers ached with cold despite her gloves. Another sound. Not a twig. Too soft. Like something dragging itself through the undergrowth. Aurora took a step forward, into the circle. The moment her foot crossed the threshold, the world tilted. Not like a stumble—more like gravity shifted. Her stomach lurched. She squeezed her eyes shut and reached out, catching a tree trunk. Its bark was warm. Almost hot. She opened her eyes. The grove was the same. Same standing stones. Same twisted flowers. But beyond them, the park was gone. Replaced by a twilight forest under a sky streaked with violet and gold—colors that hurt to look at. And where the streetlights had been, now only foreign constellations burned. Aurora’s pulse rocketed. She pulled out her phone. No signal. The clock read 11:47 PM, but the sky wasn’t that dark. Or maybe it was too dark in a way that made no sense. She tucked the phone away. If there was one thing she’d learned in the last year, it was that fear wasn’t the enemy. Hesitation was. She stepped deeper in. The farther in she went, the stranger the air became. It vibrated. Not sound—something lower, like the hum of a power line just out of hearing. The pendent radiated heat now, searing through her jacket. She unzipped it halfway, then pulled it over her head and let the chain dangle against her collarbone. The gem glowed a molten red, casting crimson light onto the leaves at her feet. Something moved in the undergrowth to her left. A shape. Too tall. Too slender. It emerged—not stepped, emerged—from behind a hawthorn bush, its limbs bending at odd angles. It wore a coat of moss and bracken, shifting and reweaving itself like living camouflage. Its head was small, faceless save for a lipless slit that stretched too wide when it spoke. *Aurora Carter.* It didn’t vibrate the air. It *warped* it. Like a pebble dropped into still water. She didn’t jump. Didn’t scream. She clenched her teeth. “Who are you?” *The name is given only in exchange.* “I don’t have your currency.” *You carry a piece of Dymas in your hands.* Aurora looked down. The pendant was now the size of a fist. Its gem shone like a wound. She clenched it in her fist, wincing as the warmth turned to heat. “This is mine. I didn’t ask for it.” *It asks for you.* The thing tilted its head. The moss-coat shifted. Beneath it, something writhed—an embryo curled in amniotic darkness. Aurora’s stomach twisted. She stepped back. Her boot met resistance. She looked down. The forest floor was rising around her ankles—thick vines, roots, tendrils of blackened wood knitting themselves into a net at her feet, tightening like a noose. *You came seeking answers.* “I came for my friend.” *And she is already here.* Cold horror stabbing up her spine. She wrenched her foot free just as the tendrils spasmed, gripping air. She lunged forward, dodging another grasping limb, and sprinted toward the standing stones. They weren’t where she’d left them. The circle was smaller. She’d been disoriented. Now she realized—the stones were rearranging themselves. The gaps between them pulsed with pale light, like wounds healing too fast. She skidded to a halt. In the center of the grove, something stood. It was a woman—no, a girl, maybe—wearing a coat the color of wet ashes. Her hair was the silver of moonlight on steel. She stood with her back to Aurora, arms outstretched as if embracing the darkness. From her sleeves, shadows dripped like ink. Then she turned. Her face was beautiful, but wrong—her mouth too wide, her eyes black and endless. She smiled. Teeth glinted. Eva. Aurora’s breath shattered. “Eva—?” The girl’s lips didn’t move, but a voice slithered into her mind like oil. *You’re late.* “No—no, I just got here. I came as soon as I heard—” *He’s already inside.* Aurora’s knees nearly gave. “What?” *He came with you in your pocket.* She looked down. The pendant was gone. Her jacket was unzipped. Her shirt beneath was torn—across the chest, in a jagged line where the gem had been. The skin underneath was unbroken, but tender. Raw. She fumbled at the tear. Her fingers came away red. Not blood. *Sap.* Thick, crimson sap. Like the juice of crushed berries. She gagged. The thing that wore Eva’s face tilted its head. The mouth stretched wider. Then it *smiled* with Eva’s mouth. And Eva’s voice came again, but warped, stretched thin across something vast and hungry beneath. *Aurora… I wasn’t alone when I texted.* The forest exhaled. The standing stones groaned. The pendant—still clutched in her trembling hand—pulsed like a dying star. She had come looking for a door. She had stepped into the mouth of a trap. And now something was coming out.
