AI The standing stones rose from the earth like the ribs of some colossal, long-dead beast. They were oak, Rory realised, not stone—ancient, petrified wood, grey and hard as iron, and slick with a dampness that wasn't entirely water. The air around them hummed with a low, resonant frequency that she felt in her teeth.
"Right then," she murmured, shifting the weight of her rucksack. "This is it."
Nyx drifted beside her, a patch of deeper darkness against the gloaming. Their form was solid enough today, a tall silhouette with faintly glowing violet eyes. "The boundary," they whispered, their voice like wind through dry leaves. "It thins to a whisper here. A promise."
Isolde, a few paces ahead, her silver hair a beacon in the twilight, turned. Her pale lavender eyes held a knowing glint . "A promise, or a threat. The grove does not distinguish."
The seer walked without leaving prints in the soft earth. Rory had noticed it the moment they'd entered Richmond Park, but she had said nothing. She'd grown used to impossible things. Her hand went to her chest, to the faint warmth of the pendant resting against her skin. The heartstone. It had been pulsing steadily since they'd left the car park, a low thrum that answered the hum of the trees.
The air changed as they passed between two of the massive oaks. It thickened, growing heavy with the scent of wet moss, blooming jasmine, and something else—a metallic tang, like ozone after a storm.
"It's warmer," Rory said, unzipping her coat . The chill of the London evening had vanished. The light was different, too. A soft, perpetual gold that seemed to filter through the canopy from no visible sun.
Isolde gave a small smile. "Time and temperature are… suggestions here. The grove has its own logic."
Beyond the oaks, the world bloomed.
A clearing stretched before them, impossibly vast. The grass was a deep, vibrant green, studded with wildflowers—bluebells and foxgloves and others Rory had no name for, their petals glowing with a soft, internal luminescence. They swayed in a breeze she couldn't feel. The trees that ringed the clearing weren't oak or ash or anything she recognised. Their bark was smooth and silvery, their leaves a deep indigo that shimmered like beetle wings. From their branches hung long, pale tendrils that drifted with a life of their own, tasting the air.
"Whoa," Rory breathed.
Nyx flowed forward, their shadow-form stretching and thinning as they moved deeper into the light. "It has been… a long time," they said, their voice softer than usual, almost reverent. "I had forgotten the feel of this place. It breathes."
"Everything breathes here," Isolde replied, her own gaze distant . "The rocks, the water, the silence between the trees. You must be careful what you say. Words have weight ."
Rory took a step, then another. The ground felt springy, alive. She crouched and touched a patch of moss that pulsed with a faint, blue light. A jolt of energy shot up her arm, making her gasp. "It's like static."
"Life magic," Isolde said. "Raw and unrefined. The grove is a wound in the world, and magic bleeds from it."
"A wound?" Rory stood, wiping her hand on her jeans. "That's a grim way to put it."
"Truth often is."
Nyx drifted towards a small pool at the far end of the clearing. The water was perfectly still, a mirror of black glass reflecting the indigo leaves above. "There is something here," they said, their form solidifying, becoming more distinct . "A presence."
Isolde joined them, her bare feet silent on the grass. She stared into the water, her reflection wavering unnervingly. "Not a presence. A memory. A very old one."
Rory walked towards a cluster of the strange, silver-barked trees. As she neared them, she saw shapes embedded in the smooth bark—faces. Not carved, but grown, their features contorted in silent screams or serene smiles. She stopped short. "Isolde… the trees."
"They are the listeners," Isolde said, without turning . "They have stood here since before the Romans. They have heard every secret ever whispered in this grove. They are not to be trusted."
"Great," Rory muttered, stepping back. "Sentient, eavesdropping trees."
The air grew cooler as they moved past the pool, towards a path that wound through the trees on the other side of the clearing. The light dimmed, the perpetual gold fading into a cool, underwater green. The hum in the air grew louder, a thrumming that pressed against her eardrums. Sounds became distorted. A twig snapping under her boot echoed with a sharp, metallic ring that hung in the air for far too long.
"Every sound repeats three times," she observed, the words echoing back to her in a whisper .
"An echo of an echo ," Nyx said from beside her, their form a swirl of shadows. "The grove is a layered place. We are walking through the memory of a forest, as much as the forest itself."
Something flickered at the edge of her vision. Rory spun. A shape, tall and thin, like a birch tree given life, its limbs too long, its face a smooth, featureless plane of pale bark.
"Did you see that?" she asked, her voice low .
"I saw many things," Nyx replied. "That is the nature of this place."
"No, there was—" She stopped. The shape was gone . "Never mind."
They continued along the path, the trees pressing closer. The air was thick with the smell of damp earth and something sweet, cloying, like rotting flowers. The ground beneath their feet became soft, spongy, and moisture seeped through the soles of Rory's boots.
She felt a tug on her senses, a sudden, inexplicable urge to walk off the path, to the left, into a thicket of glowing ferns. The pull was strong, a magnetic force drawing her towards something she couldn't see.
"Don't," Isolde said, her voice sharp . She had stopped, her lavender eyes fixed on Rory. "Do not follow the light. The grove has its own desires. They are not yours."
Rory blinked, the spell broken. "I wasn't—"
"You were," Nyx said. "I felt it too. It pulls at the shadows within us."
They reached the end of the path, where the trees opened up into a smaller, more intimate clearing. In the centre stood a single, massive oak, its bark blackened and gnarled, its roots twisting deep into the earth. It was older than the other trees, and it radiated a quiet, immense power. The air was heavy here, charged with static.
"An altar," Isolde said, approaching the tree. "Or a tomb. The oldest ones are both."
Rory followed, her eyes fixed on the trunk. As she neared, she saw that the bark was covered in faint, glowing runes, twisting and shifting as she watched. They weren't written in any language she knew, but she felt their meaning in her bones—a warning, a greeting, a promise.
A sudden, cold dread washed over her. It was a primal fear, a feeling of being watched by something vast and ancient and utterly indifferent. The birdsong she had realised was missing the entire time they'd been here. The silence was absolute. Even the humming of the air had stopped.
"It's holding its breath," Nyx said, their voice a tremor . Their shadow form was flickering , struggling to maintain its solidity. "The grove… it is aware."
"It has been waiting," Isolde said, her gaze fixed on the runes. "For one of us." She reached out a hand, her fingers pausing a hair's breadth from the black bark.
"Isolde, wait," Rory said, her voice a dry rasp .
The seer's head snapped towards her. "The path is not for me," she said, her voice strained . "It is for you. The pendant."
Rory looked down. The heartstone was blazing , a crimson light pulsing so brightly it cast her face in red. It was hot against her skin. The warmth had become a searing heat.
She took a step forward, her hand moving to the pendant.
"What is it?" she asked, her voice barely a whisper .
Isolde's eyes were wide, her usual calm shattered . "It is the reason you are here. The grove has called to the stone. And the stone has answered."
