You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The standing stones came out of nowhere. One moment Aurora was pushing through the wet bracken of Richmond Park, her trainers soaked through and the late afternoon light going flat and grey behind the trees, and the next the ferns simply stopped, as if someone had drawn a line across the world. Beyond that line stood the oaks. She had seen old trees before. Cardiff had its share, gnarled things in churchyards and along the river. But these were not trees in any sense she understood. They rose in a rough ring, seven of them, their trunks twisted into shapes that suggested the half-remembered postures of giants — a bowed head here, a curved back there, branches flung up like arms frozen mid-reach. The bark had gone silver-grey and smooth as bone, and where the failing daylight touched it, the wood seemed to hold the glow a half-second too long. "Don't," said Nyx, and Aurora realised she had lifted her hand toward the nearest stone. The Shade stood just behind her shoulder, a darkness deeper than the gathering dusk, edges curling and uncurling at the seams the way smoke moved over still water. Their voice arrived the way it always did — not quite sound, more a pressure against the inside of her ear, a whisper that the wind happened to be carrying. "Why not?" she asked. "Because they're a threshold." The violet points of their eyes drifted to the gap between two of the trunks. "Doors don't like being touched until you've decided to walk through them." Eva crowded up between them, breath fogging, her phone held out at arm's length. The screen showed nothing but a spinning load icon and a flat white field where the map should have been. "No signal," she said. "No GPS. Rory, we walked twenty minutes from the car park and now there's no GPS." "There wouldn't be." Aurora's voice came out steadier than she felt. The pendant at her throat had gone quiet hours ago — the Heartstone only stirred near Hel, and this was something else, something older and stranger. She could feel the difference like a change in air pressure before a storm. "Isolde said we'd know the boundary when we reached it. I think this is it." "It's a bunch of dead trees," Eva said, but she didn't sound convinced, and she put the phone away. Aurora stepped across the line. The cold went out of the air at once. Not warmth, exactly — more the absence of the damp November chill that had been gnawing at her since they left the road. She heard Eva's small intake of breath behind her, and then the soft, weightless quiet of Nyx slipping through, and the three of them stood inside the ring of oaks looking at what the ring contained. It was summer here. That was the first impossible thing, and her mind kept worrying at it even as the rest of her drank it in. The grass underfoot was thick and green and dry, springing back where her wet trainers pressed it. Wildflowers grew everywhere — not in beds or clumps but woven through the whole clearing, foxgloves and cornflowers and small white star-shaped things she had no name for, all of them blooming at once though half of them belonged to different months entirely. The light came from no particular direction. It simply was, golden and low and honeyed, the kind of light Cardiff got for ten minutes on the best evening of August, held here forever. "Listen," Nyx murmured. She listened. There were no traffic sounds. No distant dogs, no aeroplanes, none of the constant low hum of London that she'd stopped hearing years ago and only noticed now by its absence. Instead there was birdsong, layered and continuous, more birds than she could possibly be hearing, and beneath it the trickle of water she couldn't see, and beneath that — she had to hold her breath to catch it — a sound like a single sustained note from a glass rim, so faint it might have been inside her own skull. Eva had crouched by a patch of foxgloves. "Rory," she whispered. "They're moving." They were. As Aurora watched, the tall purple spires turned, slow as sunflowers, their bells angling to face the three intruders. When Eva shifted her weight, they tracked her. When Aurora took a step, every flower in the clearing leaned a few degrees toward her, a thousand small mouths turning to taste her presence. "They're curious," Nyx said. "Mortals don't come often. Stay on the path." "What path?" The Shade extended one long arm — solidifying as they did it, the smoke gathering itself into something almost like a hand — and pointed. And there it was, as if it had been waiting for permission to be seen: a thread of paler grass winding between the flowers toward the centre of the grove, where the golden light pooled thickest. Aurora was certain it hadn't been there a moment before. She set her foot on it and started walking, and the others fell in behind. The deeper they went, the more the wrongness pressed at her. It wasn't fear, not yet, but a constant low note of unease, the body knowing something the mind hadn't worked out. She glanced down once and saw that Nyx left no mark on the grass — but then neither, she realised with a lurch, did she. Her wet trainers should have darkened the dry blades. The grass simply rose again behind her step, unbruised, as though the grove were quietly erasing her. "How long have we been in here?" she asked. Nyx's eyes flickered. "Don't ask that question. The answer changes depending on which side of the stones you're standing on, and asking makes it worse." "That's not an answer." "No. It isn't." There was something almost gentle in the whisper. "Time runs sideways in here, Aurora. An hour to us might be a minute to the city, or a week. Isolde lives in the slack of it. We don't. So we'll do this quickly, and we won't eat anything, and we won't drink anything, and if she offers you a gift you'll take only what I tell you to take." "You said gift like it's a trap." "Among the Fae," Nyx said, "it usually is." They came to the heart of the grove. Here a spring welled up between mossed stones into a shallow pool so clear it looked solid, and around it the flowers grew tallest, brushing Aurora's shoulders. The single glass note had grown louder. She could feel the cold weight of the Fae blade in her jacket — Isolde's last gift, given the last time, faintly luminous now even in this directionless gold, as if it recognised the place that had made it and was glad, or afraid, to be home. Eva had gone very still. "Rory," she said softly. "There's someone here." There was. On the far side of the pool, where the light bent strangely, a figure stood among the foxgloves — silver hair to the waist, pale eyes the colour of the cornflowers, leaving no shadow and no footprint in the impossible summer grass. "You came back," said Isolde, and smiled in a way that answered nothing at all. "I knew you would. I have been knowing it for three hundred years, and for the length of an afternoon, which are the same length, here."
