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 Grove swallowed sound the moment Rory stepped past the oak standing stones. Richmond Park lay behind her. Traffic on the A308 still hummed beyond the tree line, dogs barked after dark, a plane cut a low lane toward Heathrow. Then the stones framed her shoulders and all of it cut off. No hum. No bark. Air turned close and warm, thick with the smell of turned earth and wildflowers. Wildflowers bloomed year-round in the Grove. That was the rule. That was what Isolde told her. Rory stared at them now. In the dark they held colour they had no right to hold. White campion and bluebells open in November, heads up, vivid under moonlight that did not match the moon over London. The Heartstone Pendant rested against her sternum. Silver chain cold at the nape of her neck, thumbnail of deep crimson glass warm through her t-shirt. She had come because the note said to. Plain paper. No signature. Slipped under the door of the flat above Silas' bar while she slept after her shift for the Golden Empress. *Midnight. The Grove. Come alone. Bring the stone.* Yu-Fei would have told her to bin it. Eva would have told her to call the police. Brendan would have quoted statute at her. Rory came anyway. She tugged the chain free so the pendant hung outside her shirt. The stone pulsed. A slow throb of heat against skin. Not a glow. Not yet. A push, pull. Like a second heartbeat out of sync with her own. "Hello?" Her voice left no echo. The trees ate it. Oaks crowded close, trunks wide as cars, bark fissured and black in shadow. The clearing itself measured no more than thirty feet across, grass knee-high and soft, the standing stones a broken circle. "If this is a joke it stops being funny now." No answer. She shifted her weight. Trainers sank into moss. She checked her phone. 00:07. No signal. No time stamp tick. The screen lit her face blue, washed her bright eyes to grey, threw her straight black hair into sharp relief. The crescent scar on her left wrist caught the light, pale as paper. She pushed the phone into her pocket. Wind moved the high canopy. Leaves shivered. The wildflowers did not. Rory frowned. She took a step toward the centre of the clearing. The pendant throbbed harder. Heat spiked, then eased. Now the inner glow woke. Deep crimson bled through the stone, lit the hollow of her throat, threw red onto her chin. A sound cracked the quiet. A twig snap, off to the left beyond the stones. Clean. Sharp. Distinct. Rory snapped her head toward it. Nothing between the trunks but dark and more dark. She held still and listened. Another sound followed. Not a twig. A footfall. Grass compressed under weight. Then another, a few paces off, near the east stone where lichen made a pale handprint on the rock. She swallowed. "Isolde?" The name fell flat. No one stood there. The grass by the east stone shivered though no wind touched it. A ripple ran through the bluebells, a line as if something brushed them at calf height and passed. Rory stepped back. Her heel found stone. She pivoted. The west side of the clearing now held a shape she had not seen when she entered. At the treeline, between two oaks, a gap showed where no gap had been. Darker than night, narrow as a doorway. The air around it bent. She knew that bend. She had seen it in Dymas, in the cellar under the Empress, in the alley behind Silas' when the Hel portal tore open last spring. The pendant burned. Not warm. Hot. The silver chain stung the back of her neck. Rory clenched the stone in her fist. The heat bit her palm. "Stay shut." Her whisper shook. "You stay shut. You stay shut, you hear me?" The gap breathed. No light came from it. No sound. The grass before it lay flat, pressed outward in a circle, as if wind blew from inside the gap though the air in the clearing stayed still. Movement flickered at the edge of vision. Left. Gone when she looked. Right. Gone again. She turned in a tight circle. Her breath came short. She counted the stones to ground herself. One. Two. Three. Four. Five of the great oaks stood sentinel. Six- Six. There had been five when she entered. She was sure of it. The sixth stone stood behind her, half-sunk, moss on its north face, lichen on its south, though she had not passed it. The standing stones marked the boundary. That was the rule. You did not cross them after dark without invitation. She stood inside the circle now. She had crossed. A rustle moved through the grass. Not wind. A pattern. A circle around her, just beyond arm's reach. The bluebells bowed in sequence. Tip, tip, tip, round and round. The sound of bare feet on soft ground threaded between the rustle, light, deliberate, numerous. One set. Then two. Then three? Rory pressed her back against the newest stone. Rough bark snagged her jacket. Stone held cold even through fabric. "Who is there?" Silence answered. Then a giggle. High and thin and wrong. It came from overhead, though no branch hung low enough to hold a child. It came from below, from the soil at her feet. It came from inside the gap. Rory squeezed the Heartstone until her knuckles went white. The glow leaked between fingers, painted her jaw red, threw her shadow long behind her onto the grass. The shadow stretched toward the gap. It stretched too far. Her head's shadow touched the dark doorway though she stood ten feet away. Another giggle chased the first, adult now, wet, close to her ear though no body stood there. She jerked. Her elbow cracked against stone. Cold brushed her ankle. Fingers? Grass? She kicked out. Nothing met her foot but air and flower heads. The cold lingered, a ring around the bone. The pendant pulsed in time with the footfalls now. Heat, pause, heat, pause. In that pause, between beats, the Grove held a different quiet. A listening quiet. As if the trees held breath. Rory forced air into lungs. She looked at the gap. The dark inside it shifted. Not depth. Surface. Like oil on water, like skin. She needed to move. Time moved different here. Her phone said 00:07. Outside, minutes or days could have passed. If she stayed till the pulse matched her heart, the doorway would open. She knew that. The stone told her. She pushed off the rock. She drove for the south stone, the one she entered through, the gap between oak and rock where London waited. Trainers crushed campion. Scent burst sharp, too sweet. Halfway across the clearing her shadow snagged. The red light from the pendant threw it ahead. The shadow did not move when she moved. It stayed stretched toward the dark doorway, head connected to her feet but body elongated, arms too long, fingers splayed wide. Rory froze. Her own legs still churned. The shadow stayed. She yanked the pendant up, chain taut against throat. Light flared. Shadow snapped back to her heels, correct shape, short and bunched. Grass sprang upright all at once around her with a soft pop. The footfalls stopped. The giggle stopped. For a span of three heartbeats the Grove held absolute still. Even the leaves ceased their shiver. Flower heads locked in place, too vivid, too open, faces turned not to moon but to her. Then the grass by her right trainer depressed. A clear print formed. Five toes. Narrow. Bare. Fresh in the dew. No leg above it. No body to make it. Just the print, then another, and another, walking away from her toward the east stone, each press slow, each blade of grass bent precise under invisible weight. Rory stared at the prints. The pendant burned a white-hot line across palm. The gap between the oaks widened an inch. Air from inside it reached her face, cold as a cellar, smelling of river mud and old pennies. A cold hand brushed the crescent scar on her left wrist. She flinched. Her fist opened. The Heartstone swung free on its chain, blazing crimson, painting the whole clearing red, and in that red light she saw them. Lined between the trees. Just beyond the stones. Still as the stones themselves. Tall. Thin. Shoulder to shoulder. Faces turned down. Hair like moss. Their eyes caught the pendant light and threw it back. Rory sucked in air. The sound she made was thin.
