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 air changed the moment they crossed the standing stones. Rory felt it first in her teeth — a faint vibration, like the lowest note of an organ played somewhere deep underground. The wildflowers pressing against her ankles were wrong for February. Snowdrops and bluebells and something bright yellow she couldn't name all growing together, all flowering at once, their petals catching light that seemed to come from no particular direction. "Keep moving." Nyx drifted at the rear, their form half-dissolved into the shadows between the oak trunks. The trees themselves were ancient, bark split and gnarled into shapes that suggested faces if you looked too long. Rory stopped looking. The grove opened ahead of them without warning. One moment she was pushing through a curtain of trailing ivy, and then she was standing in a clearing that had no right to be as large as it was. Richmond Park sat on the other side of those standing stones, joggers and dog-walkers and the ordinary noise of a city afternoon. In here, the silence pressed against her eardrums like deep water. "It's bigger inside," she said. "Most things are." Nyx moved past her, their violet eyes cutting slow arcs across the clearing. The grass underfoot was the colour of malachite, each blade precise and upright, untouched by wind. Rory crouched and pressed her palm flat against it. Cold. Not winter-cold but something older than seasons, a cold that lived in the absence of something rather than the presence of temperature. At the centre of the clearing stood a tree unlike the oaks at the boundary. Its trunk was pale silver-white, smooth as poured wax, and it split thirty feet up into a canopy of branches so fine they were nearly translucent. The leaves — if they were leaves — were thin as paper and the colour of a midwinter moon. They made no sound when they moved. Rory watched them for a long moment before she realised there was no wind to move them. The Heartstone pendant warmed against her sternum. She pressed a hand to it through her jacket and looked at Nyx. "Not a Hel portal." Their voice came out at the edge of hearing, the shape of a whisper rather than real sound. "Something adjacent. Something old enough that the boundary doesn't distinguish." "That's reassuring." "It wasn't meant to be." Rory straightened and scanned the perimeter. Where the tree's roots broke the surface they arched like cathedral ribs, carving channels through the grass that held a liquid that wasn't quite water. It sat perfectly still, deep blue, reflecting the grey February sky above them with too much clarity, too much detail. She leaned over the nearest channel and saw clouds moving in the reflection that weren't moving in the sky above. Different sky. She stepped back from the edge. A sound reached her from the far side of the clearing — not an animal sound, not wind, but something rhythmic and low that her mind kept trying to resolve into music and couldn't quite manage. It rose and fell in a pattern that suggested language more than melody. She found herself leaning toward it before she caught herself. "Don't." Nyx appeared at her shoulder. "Fae groves sing. It's not an invitation." "What is it?" "The grove recognising you're here. Deciding what you are." Rory's hand found the Fae blade at her hip without her consciously reaching for it, fingers curling around the hilt. The moonsilver was cold through her glove. It had been cold since Isolde pressed it into her hands three weeks ago with eyes like pale lavender stones and a riddle she still hadn't unpicked, and somehow that cold had become a familiar thing, a reliable thing. She didn't draw it. The light shifted. It had been doing it steadily since they entered, cycling through the warm gold of late afternoon and something bluish and diffuse that suggested cloud cover, moving through the changes too fast and too slow by turns, like watching time-lapse footage of a sky she didn't recognise. She checked her watch. The hands sat still. "Nyx." "I see it." "How long have we been in here?" "Time is contextual in a place like this. What matters is what we're here for." Isolde. Rory repeated the name to herself like a ward against the grove's strangeness. They were here for Isolde, for the prophecy that might explain what was leaking through the Veil into the city, for the answer to why every demon they'd tracked over the past month had been moving in the same direction. They weren't here to be seduced by impossible flowers and a tree that breathed without breathing. The singing sharpened, and a figure stepped out from behind the silver tree. She was tall for someone who stood so lightly, her silver hair loose and moving in that absent wind, and she carried herself with the particular stillness of a person who had long since stopped being startled by anything. The pale lavender eyes found Rory immediately and held there, not moving to Nyx, not scanning the clearing. As if she'd known exactly where to look. Her feet left no impressions in the malachite grass. She stopped ten feet away and said nothing. The grove's singing had stopped the instant she appeared, and the absence of it left a silence with texture, with weight. Rory met her gaze. "We came because you summoned us." The corner of Isolde's mouth moved. Not quite a smile. Something more precise than that. "I summoned the question," she said. Her voice belonged in this place — layered, resonant in frequencies that sat beneath normal speech. "You are only the mouth it chose to ask with." "We need to know what's coming through the Veil." Isolde tilted her head and looked at Rory the way a jeweller looks at a stone she hasn't yet decided to cut. "What is coming," she said, "has already arrived. You simply haven't learned to see it with the correct eyes."
