AI The thrum against her ribs was the first warning.
Aurora pressed her palm against the Heartstone pendant, feeling its unnatural warmth through the fabric of her jacket. It pulsed like a second heartbeat, insistent and alien. Before them, the ancient oaks of Richmond Park seemed to lean inward, their branches knitting together into a lattice of shadow that swallowed the afternoon light.
“Something’s changed,” Aurora said, her voice low . The air here tasted of ozone and crushed mint, a scent so potent it scraped her throat.
Nyx, a silhouette of deeper darkness against the gloom , tilted their head. “The Veil thins. We stand in the threshold.” Their voice was a rustle of dry leaves, seeming to come from everywhere at once.
Isolde Varga glided forward, her silver hair a streak of mercury in the dimness. Her lavender eyes were wide, unfocused, seeing something beyond the bark and soil. “The Grove remembers the steps of those who trespass,” she murmured. “It learns.”
Aurora didn’t need the Seer’s riddles to feel it. A pressure built behind her eyes, a low hum vibrating in her molars. She took a step over a gnarled root that looked like a clenched fist , and the world shifted.
The temperature dropped. The rich, damp scent of English woodland vanished, replaced by the crisp, metallic tang of high-altitude air and the strange, sweet perfume of flowers that had no name in any Earthly catalogue. The ground beneath her boots, previously soft with leaf litter, became firm and smooth, like polished stone.
They stood in the Fae Grove.
It wasn’t a clearing so much as a cathedral woven from nature. The trees here were colossal, their bark shimmering with an oily, iridescent sheen like beetle wings. Instead of branches, great, fan-like fronds erupted from their trunks, each one a mosaic of living colour—amethyst veins in jade leaves, gold dust on crimson petals. The sky above was not a sky but a dome of woven twilight, a permanent state of exquisite dusk where constellations of luminescent insects drifted like lazy sparks.
A faint, melodic chiming filled the air, not from any visible source, but as if the atmosphere itself was ringing . Aurora turned, taking it all in. Paths of crushed, glowing moss radiated from their position, leading deeper into the impossible grove. Between the trees, pools of liquid silver reflected the strange light, their surfaces perfectly still until a ripple, with no apparent cause, would disturb them.
“It’s beautiful,” she breathed, the word feeling inadequate.
“Beauty is a lure,” Nyx whispered, their form condensing, becoming more solid . Their violet eyes, usually faint, burned with intensity . “Feel the tug. The wrongness.”
Aurora did. Beneath the wonder, a current pulled at her, a gentle but insistent tug in the direction of the largest tree, its trunk so wide it could have swallowed a London double-decker bus. The Heartstone’s warmth intensified, pointing her toward it.
“Time shifts,” Isolde stated, picking a flower with seven sapphire petals that grew from a crack in the crystal -like ground. The moment she plucked it, another identical blossom bloomed in its place. “An hour here may be a minute gone. Or a day. It is rude to wear watches in polite company.”
They moved along the central path, the glowing moss muffling their footsteps into silence . Aurora reached out to touch the bark of a shimmering tree. It was cool and smooth, like water-worn glass, and a faint vibration hummed up her arm. She snatched her hand back.
“Don’t touch what you don’t understand,” Nyx warned, though their tone held curiosity, not alarm . They reached out a tendril of shadow from their sleeve, letting it brush the same surface. The darkness recoiled as if stung. “Interesting. Warded against uninvited essence.”
A sound echoed from the path ahead. A splash. Then another. A rhythmic , gentle pattering, like water dripping into a deep well.
They rounded a curve of towering, fan-like fungi that pulsed with a soft, internal light. The source of the sound revealed itself. A small creek cut across the path, but it flowed uphill, its water the colour of liquid amber. At its edge, a figure knelt.
It was humanoid, but wrong. Its limbs were too long, its skin the pale, veined green of a new leaf. It was scooping water with hands that had six slender fingers, letting it pour through them in an endless cycle. As they approached, it turned its head. It had no face, just a smooth, polished oval of the same green skin, yet Aurora felt its regard like a physical touch.
“Hollow,” Isolde whispered, a rare note of caution in her melodic voice. “Gardeners of the border. Do not engage.”
The Hollow regarded them for a long, silent moment. Then, with a motion too fluid to be natural, it stood, bowed its head in a gesture of eerie grace, and melted into the trunk of a nearby tree as if it were made of smoke.
Aurora let out a breath she didn’t realise she’d been holding. “A ghost?”
“More like a function,” Nyx replied. “A piece of the Grove’s consciousness, wearing a shape.”
They pressed on. The environment grew denser, more alien. Structures emerged between the trees, not built, but grown: arches of living wood, spiralling staircases of polished stone that led to platforms suspended in mid-air, cradling nests of spun moonlight. The air grew thicker, humming with a energy that made Aurora’s teeth itch and her skin prickle. Strange, chitinous creatures with wings like stained glass flitted from bloom to bloom, their buzzing harmonising with the ever-present chiming.
Aurora’s hand went to her belt, where the moonlight-hilt of the Fae-forged dagger Isolde had given her rested. Its familiar cold weight was a comfort in this sea of beautiful unease. The pendant’s pulse was now a steady, warm beat against her sternum.
“The heart of the Grove,” Isolde said, stopping so abruptly Aurora nearly walked into her. “It feels the return of its stolen child.”
Before them, the path opened into a perfect circle. At its centre stood not a tree, but a crystalline monolith, twice Aurora’s height, emitting a soft, internal light that cycled through every colour of the visible spectrum. Runes, similar to the ones she’d seen in old manuscripts, crawled across its surface, rearranging themselves in a slow, hypnotic dance .
“The Locus Stone,” Isolde murmured, her lavender eyes reflecting its kaleidoscopic light . “Memory of the realm. It sees all who enter.”
As if responding to her voice, the light from the stone intensified, focusing into a tight beam that shot directly at Aurora . She flinched, throwing up a hand, but the light didn’t burn. It was a cool, probing sensation, as if something was reading her bones.
Images flashed in her mind’s eye: her cramped London flat, the sizzle of wok oil from the Golden Empress, Eva’s worried face, the feel of Evan’s hand gripping her arm. Then, a sharp, jarring image: a vast, warm sky the colour of amber, sprawling vineyards heavy with strange fruit, and a low, guttural chant that vibrated in her chest.
The Heartstone against her ribs flared with agonizing heat. She gasped, stumbling back.
“Aurora!” Nyx was beside her in a swirl of shadow, a cool, dark presence against the searing light.
The beam from the Locus Stone snapped off. The runes on its surface rearranged violently, forming a new pattern—a warning. The chiming in the air changed, becoming a deeper, tolling note, like a distant bell.
From the paths radiating out of the circle, shapes began to emerge. More Hollows, dozens of them, their faceless heads tilted in unison. And behind them, gliding with impossible smoothness, came creatures of a different sort—gaunt, elegant beings with skin like polished ebony and eyes that burned like dying stars. Fae nobility, the Seer’s estranged kin.
They did not speak. They simply filled the paths, an elegant, silent cordon.
Isolde turned to face them, her silver hair lifting on a breeze that touched nothing else. She spread her hands, palms out. “I am Isolde Varga. I walk the old paths. These are my companions. We seek no war.”
A single Fae, taller than the rest, stepped forward. Its face was a masterpiece of cruel, geometric beauty. Its lips moved, and the voice that emerged was like the shattering of crystal .
“You seek what you lost, half-blood.” Its star-filled eyes fixed on Aurora, on the pulsing heat at her chest. “And you bring a thief back to the scene of the crime.”
The Heartstone’s warmth turned to a burn that shot up Aurora’s arm. The amber sky from her vision swam in her mind. The distant guttural chant became a roar in her ears, and the ground beneath the crystalline monolith began to tremble.
