You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The standing stones watched them pass. Rory felt it first in the soles of her boots — a hum that travelled up through bone rather than ear, the kind of sound that bypassed hearing and lodged somewhere behind the teeth. She paused between two moss-bearded oaks and pressed her palm flat against the nearest trunk. The bark was warm. Not sun-warm. Something else. "Don't dawdle," Isolde called from ahead. Her bare feet made no mark in the dew-silvered grass, while Rory's left a neat trail of crushed green behind her. "The path doesn't wait on politeness." "It's a path. Paths wait on everyone." "Not this one." Nyx drifted at Rory's shoulder, less a shape than a cold spot that occasionally remembered to look like a man. "She's right, Rory. Keep moving." Rory took her hand off the tree and the hum let her go, reluctant as a cat. She caught up. Past the last of the oaks, the grove opened. For a breath she couldn't understand what she was seeing. The sky overhead was English — grey October afternoon, one rook wheeling — but the light inside the clearing came from somewhere else entirely. It poured sideways through the air like honey through water, gold and slow, settling on the grass in pools that didn't match the angle of any sun. Wildflowers bloomed in improbable congregations: bluebells tangled with poppies tangled with things that had no name, purple bells the size of Rory's fist that chimed faintly when the breeze touched them. "Oh," Rory breathed. "Yes," said Isolde. "That's the usual first word." A brook wound across the clearing, and the water ran the wrong way — uphill, lazy, into a basin of pale stones that should have overflowed but didn't. When Rory knelt to look, she saw her own face in the current, and then, a beat late, her face as a child, and then her face as something older than she'd ever been. She stood up fast. "Don't stare into it long," Isolde said, not unkindly. "The water remembers more than you do." Nyx had gone ahead, their silhouette sharpening in the amber light until they looked nearly solid — a tall figure in dark coat-shapes, violet eyes lit like pilot flames. They crouched beside something in the grass. "Carter. Come see this." She went. At their feet, half-swallowed by clover, lay a ring of flat stones set into the earth. Each was carved with a symbol she didn't recognise, though one of them — a spiral bitten through by a jagged line — made the Heartstone at her throat give a small, warm thud, like a second pulse catching up with her first. "That's not good, is it," she said. "It's not nothing." Nyx's voice came thin, a whisper stitched onto wind. "This is a ward ring. Old. Older than Isolde, I'd wager." "You would lose that wager," Isolde said from behind them, amused. "But not by much." Rory pressed a hand over the pendant. It beat against her palm. "Is there a portal here?" "There was. Long closed." Isolde traced the air above the stones without touching them. "The Veil is thin in this grove — that is why I keep it. But thin is not the same as open. Your trinket senses the memory of a door, nothing more." "Comforting." "I did not say comforting. I said true." They moved on, deeper. The clearing was larger than it had any right to be; Rory had walked in under an arch of oaks she could still see when she glanced back, but the ground ahead stretched in soft folds of meadow toward a stand of silver-barked trees that certainly hadn't been visible from the threshold. The chiming flowers thickened. A dragonfly the size of a sparrow flicked past her ear and vanished into a patch of light that closed behind it like a mouth. "Tell me that was a dragonfly," she said. "It was a dragonfly," Nyx obliged. "In the sense that what you call a dragonfly and what it is share one syllable." "Helpful." Under the silver trees, the temperature dropped. Rory's breath caught white in the air — here, of all places, where a yard back she'd been warm through her jacket. The Fae blade at her hip, which had been a dull weight all morning, began to sing, very softly, against her thigh. Not a sound so much as a vibration, the way a tuning fork spoke to the bones of the hand that held it. She drew it halfway. The moonsilver caught the crooked light and threw it back doubled, a pale flare along the leaf-shape of the blade. Isolde glanced over her shoulder. Her lavender eyes narrowed, pleased. "It knows where it is. Good. A blade that remembers its forge is a blade worth keeping." "It's humming." "It's greeting kin. There are roots of the Courts beneath us here. Not deep, but present." She gestured at the silver trees. "These are children of the Elder Grove. Saplings, by our measure. A mere thousand years." Rory slid the blade home. "Saplings." "Do not touch their bark with bare skin. They remember touches." Nyx had stopped a few paces ahead where the silver grove opened onto a pool. It wasn't a big pool — you could have crossed it in three strides — but it was impossibly black, so black that the gold light refused to land on its surface and slid instead around its rim, leaving the water a flat, drinking darkness. "Don't," Isolde said, before anyone asked. "Wasn't going to." Nyx tilted their head. "What does it show?" "Whatever you need least to see." Isolde settled herself cross-legged on a flat stone by the pool's edge, her silver hair pooling around her like its own small flood. "Sit. Both of you. You came for answers, and the grove will allow me three, if I phrase them prettily." Rory lowered herself onto the grass. It was warm again — the cold had stayed under the silver trees like a held breath. Somewhere behind her the bell-flowers chimed a run of notes that almost made a melody and then thought better of it. "Prettily," she repeated. "Right. No pressure." Isolde's mouth curved. "None at all."
