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.

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 air in Richmond Park hung thick and unmoving, something Rory had only felt during summer storms over the Thames. No breeze stirred the oaks, no owls called from the dark—just the occasional rustle of something unseen skittering through dry leaves. The standing stones loomed ahead, their oak bark blackened as if scorched by some old fire, though Rory knew they’d been seasoned green. She stopped at the grove’s edge, fingers tightening around the Heartstone Pendant beneath her shirt. It pulsed once, a slow, deliberate thump against her sternum. Something watched. She exhaled through her nose, feeling the evening’s damp seep into her lungs. The last of the twilight bled from the sky, leaving the grove in bruise-purple dark. Only the stones cast any light, their edges glowing faintly, like embers beneath ash. “I’m not afraid of the dark,” she muttered. The words sounded hollow. The grove didn’t care. Rory stepped forward, boots crunching on brittle beech husks. Ahead, a ring of wildflowers blushed white even in near-darkness, their petals dusted with silver pollen that shimmered when she shifted her weight. The air smelled sickly sweet—like fermented berries left too long in a jar. She wrinkled her nose. Then a sound. A wet, clicking noise, like bones tapping against glass. It came from the trees on her right—fast, uneven. Not a footstep. Not an animal. Something that dragged itself. Rory kept walking. The pendant flared sudden, searing against her skin. She flinched, clawing the chain over her head. The gem dangled, deep crimson heartbeat pulsing faster now, syncopated—like a second pulse in her throat. “Okay,” she breathed. “Bad sign.” She didn’t stop. The grove had called her here for a reason. She remembered the letter left on her doorstep three nights ago, typed in uneven block letters: *Find the Heartstone. The gate opens at midnight. He’s coming through.* No signature. Just a smudge of berry-colored ink like crushed petals. She reached the center of the standing stones. Five oaks arced inward, their trunks forming a rough circle with a flat slab of slate in the middle—an altar? Her shadow stretched unnaturally long, stretching toward the stones as if pulled by invisible strings. Then the leaves behind her stopped moving. Not a halt. A halt from life. Like something had paused the forest itself. Rory didn’t turn. Didn’t breathe. “You’re early,” said a voice from the dark. It wasn’t human. The vowels stretched too wide, the consonants like wet fingers dragging across stone. It came from everywhere at once—not localized. Not her ears. Not her mind. Everywhere inside her, as if spoken through bones. She swallowed. “I didn’t know when ‘early’ was.” Silence answered. Then a slow laugh, a ripple of sound that vibrated in her teeth. “Time bends here,” the voice said. “You’ll learn. We all do.” Behind her, the undergrowth tremblednot with wind, but with something lifting. Branches creaked upward, snapping like arthritic fingers. Roots writhed, exposed and glistening. The trees weren’t bowing. They were reaching. Rory’s pendant burned white-hot. She clutched it, searing her palm. The crimson faded, turning to a dirty, weeping black. A shadow detached from the standing stones. Tall. Too tall. Its form rippled at the edges like candle flame in water. A man? Not anymore. Its face—when it finally turned to face her—was a shifting mask of bark and bone, two hollows where eyes should be, mouth a jagged slit filled with pale, glistening things that looked like maggots. “Evan?” she said. It wasn’t Evan. Not truly. Evan lived in hospital now, voice fractured in her voicemail, skull stove in by a wrench she kept under the sink. This thing wore Evan’s shape like a borrowed coat—stretched too tight across the wrong shoulders. “I am what he became,” it said. “What he *had to* become.” Rory didn’t flinch. Didn’t break eye contact. She’d stared down barristers in wigged fury, had seen Eva’s bruises black-and-blue under fluorescent lighting. She knew how to face monsters. “He’s not coming through,” she said. “Not on my watch.” The thing tilted its head. The mouth split wider, not in joy—something biological giving way. “You don’t decide,” it whispered. “The gate chooses who passes. And *you* brought the key.” It raised a skeletal hand. The sleeve of Evan’s old denim jacket fluttered—Evan who’d pried her front door off its hinges, Evan who’d laughed when she sobbed that night in the alley behind the Golden Empress. The sleeve didn’t move. The arm wasn’t attached. It hung suspended, a marionette string fading into the dark. The Heartstone pendant split open. Not cracked. *Split*—like a fruit overripe. A gout of black smoke erupted, weaving between Rory’s fingers. It tasted like copper and rust. The pendant’s glow died. The grove screamed. Not once. A thousand shrieks at once, rising like steam from dry ice. The standing stones cracked with a sound like gunshots. Dark fluid welled from the fissures, creeping across the slate altar. The trees groaned, their bark blackening in spreading veins. Rory stumbled back, boots slipping on wet moss. Her pendant dripped black now, like blood from a wound she couldn’t see. “You can’t close it,” the thing hissed. “It’s already open. He’s halfway through.” From the center of the altar, the slate slab *moved*. Not shifted by wind. Lifted from below by unseen hands. Something pushed upward—something long, pale, segmented. A leg? A ribcage? It uncoiled slowly, slick with membrane and ichor. Rory knew anatomy. It was a ribcage. And something inside it was breathing. She bolted.
