You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

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. </instructions>

The night swallowed the car whole the second Aurora Carter switched off the engine. No traffic sounds, no distant hum of civilisation—just the rasp of her breath fogging the windshield, the occasional pop from the engine cooling. She stepped out. Cold bit through her thin jacket. Richmond Park didn’t smell like a city park at night. It smelled old. Wet. Like iron and rotting leaves and something else—something faintly metallic beneath the damp earth. She hadn’t expected the trees. Not like this. Not a stone’s throw from the motorway, a place she’d cycled past dozens of times—verdant, open, deer grazing under cloud-filtered moonlight. But here, towering ahead, the oaks were wrong. Black bark blistered like charred skin. Leaves not green but a bruise-coloured purple, trembling when no wind stirred. The trunks leaned inward, curving toward an invisible centre like fingers pressing into a wound. Aurora zipped the jacket higher. The pendant beneath her collar warmed against her sternum, a heartbeat of its own. She hadn’t worn it tonight. Not voluntarily. It’d appeared yesterday on her doorstep, wrapped in yellowed paper, no note, scented faintly of cinnamon and gunpowder. Eva would’ve said it was cursed. Silas would’ve said drink more whiskey. But she’d pulled the chain over her head anyway. Old habit—some habits die hard. The standing stones were there, half-hidden in the undergrowth. Three oaks, knife-scarred, their grain spiralling counter to nature. She’d read about them once—folklore, a local legend about a grove that didn’t belong. But folklore didn’t explain the absence of stars. No light pollution should erase them like this. Only the sickly silver glow of the stones, pulsing faintly, like a dying breath. She didn’t want to go in. Yet her boots moved forward, drawn by the same stupid curiosity that had dragged her to Cardiff docks at midnight, or through Eva’s burning flat six months ago. When has fear ever stopped the wrong thing from happening? The first step inside the ring was like sinking into deep water. The air thickened. Her ears popped. The pendant flared—deep crimson glow leaking through her collar, warm against her throat. She pulled it out. The stone thrummed like a plucked violin string. Not warm. Hot. Almost burning. A whisper slithered through the trees. Not in Welsh. Not in English. A language of clicks and sibilants, like stones grinding together beneath a glacier. It came from everywhere and nowhere. She spun. Shadows clotted like ink. Twigs snapped. Too loud. Too deliberate. Like something testing weight. “Who’s there?” The words hung too long. Echo? No. Too slow. Too wet. The air itself seemed to drink her voice. She stepped deeper. The ground changed—from grass to packed earth to something slick. She looked down. Not mud. Not blood. A thin film of dark liquid seeping from the soil, shimmering like oil on water. It pooled around her soles, then retracted, vanishing into the dirt as if hungry. Her breath came shallow. Think. Logic. Richmond Park had a perimeter. A fence. People jogging. Dogs barking. A city a metro ride away. This wasn’t real. But the pendant glowed brighter. Then she heard the child singing. It was soft. Off-key. A nursery rhyme she barely remembered— “Twinkle, twinkle, little star, How I wonder what—” The voice cracked. Not a child’s. Not quite. Too old. Too weary. Like a parent singing to a dead infant. Aurora turned again. No one. Wait. There. A figure—small, pale, standing between two trees. Hooded. But the hood was empty. No face inside. Just blackness dripping like tar. Her heart hammered the back of her ribs. The singing stopped. Silence. Not the quiet kind. The kind that felt like the world holding its breath. Then the laughter began. High. Shrill. Fully, terrifyingly human. But the figure didn’t move its mouth. Its sleeves were empty. The sound came from inside the hood. Or behind it. Or from all around. Aurora’s hand went to her hip—where she carried no knife. No pepper spray. Just her phone, battery at 12%. Useless. The empty hood turned toward her. A voice—broken, layered, like six people speaking at once—hissed from the darkness beneath the hood: “You carry the blood in your hand.” She looked down. The pendant. Not on her neck. In her hand. She didn’t remember taking it off. The stone pulsed like a fresh wound, blood-red, thick veins of light threading through it. “What does that mean?” Her voice was too loud. Too defiant. The empty hood tilted. A laugh garbled through the dark: “Child of the gatekeeper wears the heart of the hung king.” Aurora’s mouth went dry. Evan. The ex. The last boyfriend. The one who’d laughed when she said doors shouldn’t be locked at night. The one who’d taught her to hold her keys between her knuckles like a weapon. The one whose belt she’d finally cut with a kitchen knife after he’d pinned her wrist and whispered, “You’re staying.” His voice. God help her, it was his voice in the layered whisper. “I’m not his child,” she snapped. A sound like tearing silk filled the air. The trees shuddered. Leaves curled and fell like burnt paper. The ground trembled. The slick film surged upward, coating her boots, her jeans, cold and clinging. Then the pendant spoke. Not in words. In pain. A scream heralded the silent rupture. A gash opened in the air two metres ahead—no wind, no light, just a tear in reality, jagged and wet. Beyond it, not darkness. Not Fae. Not Earth. A *thing* pulsed there—something vast and many-eyed, watching through the membrane of the world. And from the tear, something crawled. Long. Thin. Too many joints. Pale as bone. Its head was a smooth dome, no eyes, no mouth. It moved toward the empty hooded figure and paused. The thing from the tear didn’t touch the ground. It hovered, dripping. Aurora’s feet refused to move. Logic screamed: *run*. But her body was locked. Years of panic training evaporated. She was a child again, frozen in the corner of a bedroom, Evan’s fist raised. The figure with the empty hood held up a skeletal hand. The crawling thing paused. “He’s here,” it whispered—through the hood, through her bones, through the pendant. The tear widened. A shape emerged. Tall. Familiar. Evan. Not the Evan from Cardiff. Not the one with stubble and a sneer and cheap cologne. This Evan was younger. Clean. Sharp cheekbones. A smile that didn’t twitch. “Ror,” he said. Not mocking. Not cruel. Just calm. “Took you long enough.” The pendant burned her palm. It was hotter than fire. Melted the skin where she clutched it. She dropped it. It hit the slick earth. Didn’t sink. Didn’t melt. It lay there, pulsing, as if alive. Evan took another step forward. His feet didn’t touch the ground. He walked on shadow. “You always did like secrets,” he said. “But this one’s mine to keep.” The crawling thing shivered. The empty hood turned toward Aurora. Her breath came in short gasps now. The world tilted. The trees groaned. She wanted to scream. But her throat locked. Evan smiled wider. “Time’s different here,” he said. “Minutes out there can be centuries in here. You could stay forever, Rory. Or I could let you leave. Just one question. Answer right, and you walk out. Wrong? Well…” He gestured to the crawling thing. “You’ve met the Hel-gate guest before.” Aurora swallowed blood. Her pulse roared in her ears. “Ask,” she whispered. Evan’s grin stretched too wide. “Who gave you the pendant?”
