AI The oak stones didn't look ancient until Rory stepped between them.
From the path in Richmond Park they had been ordinary enough — lichen-spotted, half-sunk, the sort of thing dog walkers let their dogs piss on without a second thought . Isolde went first, her silver hair catching none of the grey afternoon light, her bare feet lifting over wet grass without bending a single blade. She left no footprints when she walked. Rory had read that about her in Eva's notes and hadn't believed it until now.
"Come," Isolde said, and her voice made the air itch. "What was lost will be found where time forgets to go."
"You mean in there?" Rory asked.
Isolde's pale lavender eyes creased. "I mean precisely in there, Rory Carter who is called Aurora when she is being scolded. But the words are not the place."
Nyx made a sound behind Rory like wind through a keyhole. They had been solid when they'd left the flat above Silas' — tall enough that Rory had to tilt her head, the edges of their coat made of something that wasn't cloth — but between the two standing stones they thinned.
Rory put her hand on the stone to steady herself. It was warm. That was wrong; it was late November and frost still silvered the bracken. The stone thrummed under her palm.
The Heartstone pendant Eva claimed had shown up taped to Rory's bike helmet last spring pulsed once against her sternum. A quick, hot thump that had nothing to do with her heart. It was deep crimson, no bigger than her thumbnail on its silver chain, and it had never done that before except down by the Thames underpass where the Veil went thin enough that she could see the shimmer, the distortion like heat haze.
"Rory," Nyx whispered, and their voice came from everywhere and nowhere, a whisper carried on the wind that brushed the crescent scar on her left wrist. "It opens."
She stepped through.
The cold hit her first, then didn't. The air on the other side was not winter air. It was late summer just after rain, thick with green and rot and honey. The sound of the A3 cut off as if someone had closed a door. No planes. No dogs. Just the sudden, overwhelming drone of insects Rory could not see and the drip of water from leaves too large to belong to any oak in London.
She stood in a clearing that was bigger on the inside than the circle of stones should have allowed. Ancient oaks that were not oaks ringed it, their bark silver-white and twisting up into a canopy that filtered light the color of warm amber. Not the amber of sunset — the specific, syrupy amber she had only ever seen in cookbooks describing Dymas, the Gluttony realm under Prince Belphegor, where the sky itself looked edible. Rory had never been to Hel, but Isolde had described it while drunk on nettle wine and Rory had remembered.
This wasn't Hel. The air was too clean. Too alive.
Wildflowers bloomed everywhere, year-round impossibility: foxgloves and meadowsweet and flowers with no names, their heads open despite the fact that outside this pocket it was nearly December. Their scent was so dense it coated her tongue.
"Oh," Rory breathed.
Nyx unfolded beside her. Between the stones they had been a wisp; here they drew together, their humanoid silhouette of living shadow knitting solid, near six-two and oddly formal in the way they held themselves. Their faintly glowing violet eyes adjusted.
"A pocket," they said, quieter than usual . "Folded."
"A grove, little shadow," Isolde corrected. She was already ten feet ahead, though Rory hadn't seen her move. "My grove. And ours, now. Do you feel how it pulls?"
Rory did. The ground under her trainers gave slightly , moss thick as a mattress. Time felt wrong, like when you stare at a clock too long and the second hand stutters. An hour inside can be minutes or days outside — that was how Isolde's grove worked, and Rory had thought that was just a neat trick of Fae magic, not a physical pressure behind the ears. She swallowed and her ears popped.
She took a step forward and her boot sank a half-inch. No resistance. She looked back. She had left prints. Nyx had left none, because Nyx never really touched ground unless they wanted to. Isolde left nothing, as always.
"Stick close," Rory said, falling automatically into the cool-headed voice she used when Eva was panicking or when Yu-Fei's dinner rush went sideways. "We don't know what's stable here."
"Wise," Isolde said, but she didn't sound like she meant safety. She sounded pleased. "The rite that made this place was done before your father's fathers were dreamed of. Before Aldric's circle."
Nyx flinched at the old name. Rory noticed.
The deeper they went, the less the clearing behaved like a clearing. The oaks leaned in. Light pooled. The wildflowers got taller, up to her knees, then her waist, and they chimed when she brushed them — actual chimes, bell tones, not rustle. She reached out without thinking and the petal of something purple-black closed around her fingertip, warm and curious, then let go.
"Don't," Nyx whispered at her elbow, and the word moved her hair. "They remember touch."
Rory put her hands in her pockets. Her right hand closed around the hilt of the thing Isolde had given her three nights ago after Rory had brought her instant noodles and a spare phone charger. The Fae-Forged Blade. Even through her coat pocket it was always cold to the touch, a slender leaf-shaped dagger of moonsilver that never warmed. In the amber-tinted light filtering down, she could see its faint luminescence starting to wake through the fabric.
"It's cutting?" she asked Isolde .
"The air?" Isolde laughed, and the sound made more of those impossible flowers turn their heads. "No. Not yet. The Veil here is thin. You can see it if you try, you who wear the false heart."
Instinctively Rory pulled the Heartstone out from under her shirt. It was pulsing now steadily, warm against her skin, faint inner glow catching in the crimson. Pulses with warmth when near a Hel portal — that was what the lore forums said, but there was no Hel portal here. Or maybe there was. Rory had learned not to trust maps drawn by people who'd never crossed.
She squinted. Past Isolde's shoulder, past the curtain of flowering vines, the air did a weird thing. A faint shimmering distortion, like looking through old glass. An hour inside can be minutes outside. A tear, a thin place. Not a full rift — the Wardens would be here with salt and iron if it was — but enough.
"Is that to Dymas?" she asked, because the amber light was stronger there, and for a half second she smelled roasting meat and sugar and something dizzyingly rich.
Isolde tilted her head. "All hungry places touch all other hungry places. That is not a lie."
Right. Fae compulsion. She cannot lie but she can mislead. Great.
Nyx had gone still. The shadows in the grove were strange; they did not all fall the same way. Some stretched toward Rory, some away, some pooled around Nyx's boots like ink eager to be reunited. They were a being of living shadow, existing between the mortal plane and the spaces between realms. A man named Aldric once, in 1643, before a failed summoning. Rory didn't know how being home — if you could call the between a home — felt, but their shoulders were high.
"There's something here," Nyx said, their whisper thinned . "Under."
Rory looked down. The moss under her feet wasn't just moss. Where her boot had pressed, the green had parted and shown a surface beneath, smooth and pale and veined like marble , or like bone. As they had walked, the wildflowers had hidden it. Now that she looked, she could see it everywhere — a floor, deliberate, tessellated, ancient and too even to be natural, running under root and soil.
She crouched, brushed flowers aside. Cold bit her fingers despite the summer air. Stone, yes, but carved. Lines cut into it, spiraling in, concentric, words in a language that made her eyes water to try to read.
"Hedge-witches," Isolde said softly , and for once she did not riddle. "Before the Courts. Before your Wardens. They made a door and then were afraid of what would answer. So they made a garden on top of the door to keep it sleeping."
Unease prickled up Rory's spine, sharp as static. The wonder had been easy — the scent, the light, the chiming flowers, the sheer un-English excess of life in a London park. This was the other side of that coin. She thought of her flat above Silas' — the sound of the bar shutting, the bikes chained up, Eva laughing in the kitchen — and felt, with a lurch , that it was already a day away, or ten years away, or five minutes.
"Is it Hel?" Rory asked, hand tight on the cold dagger through her pocket. She was cool-headed, intelligent, known for out-of-the-box thinking, but her heart was hammering now.
Isolde crouched beside her, ageless face level with hers, silver hair pooling on the hidden floor without touching it. Her lavender eyes were earnest.
"It is a mouth," she said. "All doors are mouths. You need not feed it. But you, Aurora Carter, born in Cardiff to a barrister and a teacher who wanted a lawyer, you who ran — you were always going to find a door."
The Heartstone pulsed hard enough to hurt, crimson light leaking between Rory's fingers over her shirt. The shimmer ahead thickened. The warm amber sky of somewhere that was not Earth seemed, for a blink, to show the suggestion of vast orchards beyond, vineyards stretching to a horizon that curved wrong.
Behind her, Nyx's hand — when they wanted it to be a hand — settled, light as a draft, on her shoulder. Solid and cold.
"We should go back," they whispered, only to her. "The grove likes you. That is not always good."
Rory swallowed, stood. She looked down at the spiral under her feet, at Isolde's bare feet hovering above it, at Nyx's shadow stretching impossibly long toward the shimmer and their violet eyes fixed on it.
"Yeah," she said, voice steady . "Yeah, okay. We map it. We go. We bring Eva's iron."
She didn't let go of the dagger.
