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.

She had checked the coordinates twice on her phone before setting out, but the old oak trees that reared up from the darkness were nothing like the map on her screen. The Richmond Park entrance had been as it always was—wide iron gates, tidy paths, the distant murmur of late-night traffic—but beyond them, the world had folded inward. No streetlamps. No distant hum of civilization. The air smelled of damp earth and something like crushed violets, too sweet, like perfume left in a sunbaked car. Aurora pressed her palm against the silver chain of the Heartstone pendant hidden beneath her shirt. The gemstone, tucked into the hollow of her throat, should have warmed by now—should have flared if a Hel portal pulsed nearby. But it stayed cool. Patient. Watching. She adjusted the straps of her delivery bag—an old thing made of canvas, probably older than the pub upstairs—and stepped carefully over the roots that coiled across the path like serpents. Mist curled around her ankles, so thick it blotted out everything below the knee. When she exhaled, her breath didn’t immediately disperse. It hung in the air, suspended, as if the night itself had reached out and caught it. That was when she heard the first sound. Not a rustle. Not wind. No birds. No foxes. No crickets. Just… a wet, clicking noise, like teeth tapping together too fast to be accidental. Aurora froze. Listened. Nothing. She exhaled through her nose, slow and controlled. "Just your imagination, Rory," she muttered under her breath. The words didn’t reassure her. She’d come here for a reason, hadn’t she? A tip. A whisper in the back of a bar. A woman with all silver in her hair and fire in her eyes had slipped her a scrap of paper with coordinates and a warning: *Ask for the Inner Grove.* She didn’t know why the woman had trusted her, but she’d given Aurora the pendant at the same time—*for protection*. She hadn’t explained why the heartstone recognized Aurora’s bloodline, but she’d nodded when Rory said her surname, as if it meant something. The path narrowed. The standing stones—huge, gnarled, their surfaces blackened by centuries—loomed ahead. She’d seen photos, but nothing prepared her for the actual presence of them. They leaned inward slightly, as though pressing together in the dark. Their shadows stretched unnaturally long, even against the ground fog, and at their base, the earth was disturbed—not trampled, but *worked*. Scratched. Like claws. She slowed. There was no reason for her to feel like she was crossing a threshold into somewhere else. No visible doorway. Only the stones, watching. Then she heard it again. A exhalation, close. Not from her. Not from the wind. Aurora turned sharply. Her pulse kicked up, but she didn’t run. Not yet. The mist shifted at the edges of her vision—not drifting, but *retreating*, as though something had inhaled it. Shadows pooled in the crooks between roots and stones, darker than they should have been, like wells into somewhere deeper. She reached for the pendant. It was still cold. A twig snapped behind her. Not to her left. Not behind the stones. *Behind her.* From the direction she’d come. Her breath shallowened. She didn’t move. Another snap. Closer. The rhythm irregular, like something uneven on foot—limping? Or with too many limbs? She turned slowly. Nothing. The path behind her was empty. Mist. Roots. Stones. But the air had thickened. The taste of violets was stronger now, cloying, coating her tongue. She swallowed. Then the whisper began. Not words. Not quite. A voice like wind through reeds, but shaped—formed—into something linguistic, something almost *human*, except it wasn’t. It was layered. Guttural. Sibilant. And it was whispering her name. *Rory.* She flinched. *Rory, come back.* Her hands clenched into fists. She could feel the pendant pulsing—not warm, but *thrumming*, a vibration against her sternum, slow and deliberate, like a second heartbeat. “Who’s there?” she demanded, voice steady despite the tightness in her chest. The whisper didn’t answer. It dissolved into a laugh—a child’s giggle, high and wet and wrong. Aurora exhaled through her nose. Shook her head. “Is this a joke?” Silence. Then, from every direction at once, a collective inhale. She backed up. Her shoulders hit something solid. She spun. Nothing. But a shadow detached itself from the nearest standing stone. Not a shape—just *wrongness*. A distortion in the air, like heat shimmering off asphalt, only deeper. It pulsed once, twice, like a lung breathing. And then it exhaled. Cold. It rolled toward her in a wave—no physical form, just an absence given motion—and struck her chest like a gust of ice. Aurora staggered. Her lungs locked. For a heartbeat, she couldn’t draw air. The pendant flared. Not warmth. *Light.* A deep crimson glow burst from beneath her shirt, striking the oncoming darkness like a lance. The cold wave recoiled with a shriek—a sound like tearing silk and breaking glass—and the mist before her *unraveled*, threads of fog peeling away like peeling skin. Then: silence. The whisper died. The presence withdrew. But the air still hummed. Still *vibrated*. Aurora pressed a hand to her chest. Her ribs ached where the cold had struck. The pendant glowed faintly now, pulsing in time with her heartbeat, its inner glow shifting like embers in a dying fire. She took a slow breath. She wasn’t alone anymore. She turned toward the standing stones. And from deep within the mist, from beyond the ring of oak sentinels, something began to *sing*— —a note so low it wasn’t sound, but *pressure*— —and Rory realized with dreadless clarity that the grove wasn’t hiding *her*. It was hiding *them*. And they had just woken up.
