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 gate to Richmond Park was supposed to be locked after dark, but the chain hung cut and coiled in the mud like something shed. Rory told herself it was kids. Kids with bolt cutters, out here at midnight, in November. Sure. She checked her phone again. 11:47. The message had come three days ago, from a number she didn't recognize: *The grove. Before the month turns. Bring the stone, or it will bring you.* She'd spent those three days telling herself she wouldn't come. Then she'd spent tonight telling herself she'd just walk to the park, look at the stones, and go home. That had been two hours and one bus and one very dark stretch of bridle path ago, and now here she was, deep in the park where the sodium glow of London couldn't follow, and the trees had closed behind her like a door. The message had known about the pendant. Nobody knew about the pendant. She hadn't even told Eva. It hung under her coat now, a thumbnail of deep crimson on a silver chain, and it was warm. Not body-warmth warm, the way metal gets against skin. Warm the way a hand is warm. She'd noticed it on the bus, a faint pulse against her sternum in time with nothing — not her heartbeat, not the engine. She'd pressed her palm flat over it at the edge of the park and felt it beat back, faster, like a thing that had been sleeping and was waking up because it recognized where they were going. The standing stones announced themselves before she saw them. Her torch found them one by one: seven of them, oak-shaped, if oak could be shaped by anything that wasn't growth. Not carved, exactly. Grown into shape and then turned to stone, grain and bark and knothole all fossilized mid-sentence. They ringed a shallow fold in the land, and the fold was wrong. It was warm there. She could feel it from ten feet away, a soft exhalation of heat rising out of the clearing like breath from a mouth. And it was lit. Not by her torch. The fold of land glowed faintly, sourceless, the way the sky glows over a city — and inside the ring, wildflowers. A whole carpet of them, white and violet and gold, open and upright and blooming in November, in the dark, in the cold. Rory stood at the boundary for a long moment. Every instinct she had — and she'd survived Evan, so she'd learned to trust her instincts the way sailors trust weather — told her that this was a door, and that doors like this opened both ways. She went in anyway, because the message had said *before the month turns*, and tomorrow was the first of December, and because the pendant had gone from warm to hot against her chest, tugging at its chain like a compass needle. Inside the ring, the silence was total. Not quiet — silent. The moment she crossed between the first two stones, the city vanished. No traffic drone, no distant sirens, no aircraft. Not even wind. The air was still as the inside of a jar, and soft, and smelled of cut grass and honey and something underneath both of those that she couldn't name and didn't like — a mineral smell, like wet stone, like the inside of a cave that has never once been open to the sky. The flowers were worse up close. She crouched, keeping her torch low. They weren't any species she knew. Five petals each, but the petals were too symmetrical, and at their centers, instead of stamens, there was a small dark pit, a pupil-deep dimple that her torch beam would not enter. She reached toward one and stopped. The bloom — she would swear this later, swear it to herself in the small hours — turned. Slightly. The way a face turns. She stood up too fast and the pendant flared. Heat spiked through her shirt, enough that she gasped, and the crimson gem was glowing now, a faint inner light like a coal, pulsing. Pulsing in time with something. She made herself count it. Three seconds between pulses. Then two. Then two. Then two. Something else was counting with it. The first sound was a bell. One note, high and small and clear, from somewhere behind her and to the left, inside the ring. She swung the torch. Flowers. Stones. Nothing. The bell came again — behind and to the right now, and it had moved wrong, the way a sound shouldn't be able to move, and this time it was answered by a second bell, lower, from the direction of the stones she hadn't come through. The far side of the ring. Rory's mouth had gone dry. She got her phone out. 11:47. She frowned at it. She had checked it at the gate. That had been twenty minutes of walking ago, at least. 11:47. The screen dimmed. She tapped it awake. 11:47, and the battery icon was full, and the seconds in the clock were — she watched them — they were going backward. Not smoothly. Skipping. 41. 38. 41. 33. "Okay," she said, aloud, because her own voice was the only familiar thing left. "Okay, that's — nope." She turned to walk back out the way she'd come, and stopped. The stones she'd entered through were further away than they should have been. She'd crossed maybe fifteen feet of grass. The stones stood a good fifty yards off now, and between her and them the carpet of flowers stretched, and every single bloom in her path had turned. All the dark pits of all those petals aimed at her like ten thousand unblinking eyes. The bells rang again, both together, and this time they didn't stop — a thin, weaving carillon, and beneath it, faint, she heard footsteps. Bare feet on grass. Slow. Unhurried. Coming from everywhere at once, or from nowhere she could point to, and the pendant was pulsing once a second now, hot enough that she could feel it through her bra, and it was pulling. Actually pulling, the chain taut against the back of her neck, the gem straining toward the center of the clearing like iron toward a magnet. She didn't want to look at the center of the clearing. She looked anyway, because not looking was worse. The light there had changed. It had a shape now. A seam, vertical, about her height, hanging six inches off the ground — a slit of dim red light like the last coal of a fire, and it was breathing. Expanding. Contracting. In time with the pendant. In time with the footsteps. "Rory." Her name. In a voice she knew. Eva's voice, warm and amused, from just behind her left shoulder, close enough that she felt breath on her ear — and Rory did not turn around, because Eva was in Spain, and because whatever had breathed on her had too many lungs. The exhale had come in layers, three or four streams of air slightly out of sync, the way a chord is made of notes. "Rory," it said again, in her mother's voice. Then, softer, in Evan's: "You came back to me." The bells stopped. The footsteps stopped. The silence came down like a dropped curtain, absolute, pressing on her ears, and in that silence the seam of red light split wider with a sound like silk tearing lengthwise, and the pendant's chain snapped. It didn't fall. The Heartstone rose, slow and steady, a bead of crimson light climbing the cold air, drifting toward the seam, and Rory understood — with the particular, useless clarity of terror — that the message had been an invitation, and the pendant was the key, and she had carried it here herself, warm and trusting, all the way to the door. The flowers at her feet began to sing. Low, wordless, in her own voice. Rory ran. Not toward the stones — the grove had moved them, it wasn't letting her out that way — but toward the seam, because the seam was a door and doors opened both ways, and because the pendant was hers, given to her, and she'd be damned before she let anything on the other side have it back. Her torch beam jounced wildly across the turning, singing field of flowers, and behind her, something finally stopped pretending to be footsteps, and began to follow.
