AI By the time Aurora reached the edge of the grove, she already knew she had made a mistake.
Richmond Park behind her was all ordinary darkness: broad lawns silvered by a thin, weak moon, the hulking outlines of oaks, the distant gleam of London beyond the trees. She could still hear the world there. Traffic breathed somewhere far off. A fox barked. Wind moved through branches with the dry, sensible rustle of leaves.
Ahead, beyond the ring of ancient oak standing stones, the air had gone strangely still.
She stood with one hand in the pocket of her jacket, fingers wrapped around the Heartstone pendant through the fabric. It was warm enough now to feel alive. Not hot. Not painful. Just steadily, insistently warm, as if it had its own pulse and had decided to borrow hers.
Brilliant, Rory, she thought. Middle of the night, alone in a park, following a magic necklace because it felt a bit toasty.
She almost laughed at herself, but the sound died before it reached her mouth.
The standing stones were darker than the dark around them. Old oak, weathered and split, each one thick as a gatepost and twice as crooked, as if they had grown that way rather than been set by human hands. Wildflowers spilled around their bases in pale clumps—foxglove, primrose, tiny starry things she couldn’t name. In November. At half past midnight.
The pendant had started warming an hour earlier while she was trying to sleep in her flat above Silas’s bar. One minute she’d been listening to the pipes knock and someone downstairs murdering an Oasis song; the next she’d sat bolt upright with the silver chain hot against her throat. By the time she got her shoes on, the warmth had settled into a steady tug low in her chest, directional as a compass needle.
So here she was.
Aurora pulled the pendant free and let it hang against the back of her hand. Deep crimson in the moonlight, no bigger than her thumbnail, with that faint inner glow she still hadn’t found a sensible explanation for. It brightened as she stepped closer to the stones.
“Fantastic,” she muttered.
Her own voice sounded wrong. Not louder. Not echoed . Just flattened, as if the grove had swallowed everything above a whisper .
She took out her phone. No signal. That wasn’t a shock, not this far into the park, but the screen gave her a flicker of irritation she welcomed because it felt normal. 12:37 a.m.
Fine.
She slipped between two stones.
The change was immediate and subtle enough to be worse than dramatic. The air grew softer, warmer, carrying the green wet smell of summer soil. The cold on her cheeks vanished. Behind her, the park’s distant noises thinned as though someone had shut a door very carefully .
Aurora stopped.
The clearing opened around her in a rough oval, larger on the inside than it should have been. Moonlight pooled over long grass and flowers that glimmered pale blue and white. A great tree stood at the center, trunk wide as a room, bark silvered and furrowed . Low branches twisted outward like black antlers. The place was beautiful in the way some old churches were beautiful—enough to make the skin between her shoulders tighten.
She had heard about strange places all her life in the way people heard about them in Wales and politely pretended not to believe: lanes that doubled back on themselves, lights over marshes, old wells where you never looked too long into the water. Since coming to London, she had met enough impossible things to stop dismissing folklore out of hand. Still, standing here alone in a clearing that tasted of rain and secrets, she felt the old human instinct to turn around and leave before she found out what the story was really about.
The pendant pulsed once against her palm.
“Right,” she said quietly . “You brought me here. Now what?”
No answer, of course.
She started toward the central tree, placing each step carefully through the grass. Her trainers made almost no sound. That bothered her. Grass should whisper . Stems should bend and swish at her ankles. Instead there was only the light, dry thud of her heartbeat in her ears.
Halfway across the clearing she heard something move behind her.
Aurora turned at once.
Nothing. The stones stood in their ring, black and patient. Flowers nodded in a breeze she couldn’t feel. Beyond the boundary was only layered dark.
She stayed still and listened.
A faint click.
Then another.
Not from behind this time, but off to her left, near the tree line . Like someone tapping two pebbles together.
She narrowed her eyes. “Hello?”
The word barely carried.
No reply. No animal sound. No shifting footstep.
Maybe a branch settling. Maybe a deer. Maybe you should stop doing the work for the horror film and walk away.
She turned back toward the tree and kept moving.
The warmth from the pendant had grown stronger. It spread through her fingers into her wrist, licking at the small crescent scar there with an odd prickling sensation. By the time she reached the great trunk, the stone’s inner red glow was visible even in the moonlight. It painted the lines of her knuckles a bruised rose.
At the base of the tree, the earth dipped into a shallow hollow. The grass there looked flattened, not crushed exactly, more as though something heavy had rested on it without touching. The air above that patch wavered faintly, like heat over a road in summer.
Aurora crouched.
The pendant jerked in her grip.
Not imagination. Not symbolism. A real, physical pull, downward and forward, toward the shimmering patch.
Her breath slowed. Fear was there now, clean and hard, but it sharpened her rather than freezing her. She leaned in, studying the distortion. It wasn’t random. There was a shape to it—a vertical seam in the air no wider than a doorway, if a doorway had been cut into the world and then clumsily stitched shut.
A Hel portal, she thought, the phrase arriving with a cold certainty that made her wish it hadn’t.
The pendant pulsed again, hot enough this time to force a hiss through her teeth.
Then something laughed behind her.
Not loudly. Not madly. Just a quiet, familiar breath of amusement.
Aurora stood so fast her knees cracked. She spun around, pendant clenched like a weapon.
No one.
But now the silence had changed.
At first she couldn’t say how. Then she realized the grove was no longer truly quiet. Beneath everything sat a low murmur, almost below hearing. Like a crowd speaking through walls. Like voices in another room.
The hair rose on the back of her neck.
“Not funny,” she said, and hated the thinness of it.
The murmur thickened. Not words yet. Cadence. Rise and fall. More than one voice. Too many to count.
She backed away from the hollow, eyes moving from stone ring to tree line to flowers. At the edge of her vision, something crossed between two trunks—a human height, narrow, quick. She snapped her gaze toward it and found only bark and shadow.
Her mouth had gone dry.
This was the point, she told herself. The point where sensible people left. Take the warning. Go.
She took three quick steps toward the stones.
A bicycle bell rang behind her.
Aurora stopped dead.
Bright and small and unmistakable: the cheerful trill of the bell mounted on the handlebars of the restaurant’s old delivery bike. She had heard that sound in rain, in traffic, in cramped back alleys behind office blocks. She knew the bent note of it the way a violinist knew a cracked string.
It rang again, farther off now, from somewhere to her right.
“No,” she said before she could stop herself.
Then Yu-Fei’s voice floated softly through the grove.
“Aurora? You forgot the bag.”
The accent was perfect . The mild impatience. The exact pitch he used when she was about to leave without her change. For one insane second relief crashed through her so hard she nearly answered.
She bit the inside of her cheek until she tasted bloodless metal.
No one from the Golden Empress was in Richmond bloody Park at midnight.
The voices under the ground—or under the air, or under whatever layer of reality she was standing on—seemed to notice her understanding. The murmur sharpened into whispers. A dozen tones. Men, women, old, young. Familiar and not. Threads of language she knew and didn’t.
Something moved in the flowers just beyond her left foot.
Aurora flinched back. A line of white blossoms bent as if a hand were passing through them. Not the random ripple of wind. Deliberate. Traveling toward her in a straight path.
She stumbled another step backward.
The path in the flowers stopped.
The blossoms lifted again one by one, settling upright.
Then, from directly behind her shoulder, a man spoke in a low, hurt voice she had once feared more than shouting.
“Rory.”
Every muscle in her body locked.
She didn’t turn around. She didn’t have to. Evan’s voice had engraved itself somewhere deep and ugly long ago. She knew the soft coaxing tone that came before a slammed door, before hands on her wrists, before apologies that curdled by morning.
“Don’t,” she said.
“I just want to talk.”
Her chest went tight with old instinct. Run. Placate. Freeze. All three fought at once. She dragged in a breath and forced her feet to move. One backward step. Then another.
“I said don’t.”
The whispering around the grove swelled in disappointment, like an audience denied its line.
She reached the ring of stones and risked a glance over her shoulder.
There was no one at all.
Only the clearing and the tree and the moon-white flowers. Only the place where the air above the hollow was now visibly darkening, the seam in the world opening a fraction wider. The space around it had begun to bend inward. The shadows near it stretched too long.
The pendant in her hand burned.
Aurora looked from the widening seam to the stones around her. Something clicked into place in her mind—quick, cold, practical. Boundary. Marker. Threshold. The stones weren’t decoration. They were a wall of sorts, and walls only mattered if something wanted through.
The whispers changed again. One voice detached itself from the rest.
Her own.
“Aurora,” it called from the center of the grove, perfectly level, perfectly calm. “Don’t leave me here.”
She shut her eyes for one beat. Opened them. The pulse was hammering in her throat now, but her head had gone clear.
The pendant tugged toward the seam, reacting to it. If it was a key, that was bad. If it was a lock, maybe less bad.
No idea. No manual. Excellent.
She yanked the silver chain over her head and wrapped it around her fist. The heat bit into her skin. She strode three paces back into the grove before she could think better of it, aimed for the edge of the darkening air, and hurled the pendant into the hollow.
The crimson stone vanished with a sound like a breath sucked through teeth.
For a split second nothing happened.
Then the seam convulsed.
The grove inhaled.
Every flower flattened at once. The branches of the great tree shuddered. The murmuring voices rose in one furious, layered cry—not loud, but vast, as though the sound came from a terrible distance through a narrow crack. The darkness in the hollow pinched inward around the pendant’s red glow, which flashed once, violently bright.
Aurora threw herself backward through the nearest gap in the standing stones.
She hit the ground outside the ring hard enough to jar her teeth. Cold night air slammed back over her skin. Sound returned all at once: wind in the trees, traffic far away, the harsh pant of her own breathing.
Behind her came a heavy impact against the invisible boundary.
Not wood on wood. Not body on stone.
Something like a wet hand striking glass .
Aurora scrambled onto her elbows and looked.
Inside the ring, the grove had gone dim and distant, as if she were seeing it through old bottle glass. The wildflowers writhed in little concentric ripples around the central tree. At the base of the trunk, a red spark glimmered and faded. The dark seam was gone .
For a moment nothing moved.
Then a shape approached the standing stones from inside.
It was only a deeper patch of shadow at first, human in height, thin as a sapling. It stopped just beyond the boundary where moonlight failed. Aurora could not see a face. She had the queasy certainty that if she stared too hard, one would appear.
Her phone buzzed in her pocket so suddenly she nearly screamed.
She snatched it out. Full signal, absurdly. The lock screen showed six missed calls from Eva and the time in cold white numbers.
3:12 a.m.
Aurora stared.
She had left her flat shortly after midnight.
The thing in the grove lifted one arm.
No hand. No details. Just the outline of a gesture she recognized before it made sense: a small beckoning curl of the fingers, patient and intimate.
Come back.
She got to her feet and backed away without taking her eyes off it. At ten paces, the shape seemed smaller . At twenty, it was almost part of the dark. At thirty, she blinked and the clearing was just a clearing again, ringed with oak stones and impossible flowers, quiet as old sleep.
Her empty hand throbbed where the chain had burned it. She looked down. A thin red line crossed her palm. The crescent scar on her wrist stood out pale against her skin.
The phone buzzed again. Eva.
Aurora answered without looking away from the grove.
“Rory?” Eva’s voice came through sharp with worry. “Where the hell are you? I’ve been trying you for hours.”
Aurora swallowed. Her throat felt scraped out. “On my way back.”
“What happened?”
She listened to the wind drag through the park, to the traffic beyond it, to the ordinary world stitching itself together around the edges of her fear.
“I’m not sure yet,” she said.
And from somewhere deep in the pocket of darkness beyond the stones, too soft for the phone to catch and too clear for her to deny, her own voice answered, “Neither am I.”
