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 oaks loomed ahead, seven of them, spaced in a ring that felt deliberate even before Rory saw the runes carved into their trunks. Frost clung to the grass outside the circle. Inside, wildflowers — bluebells, poppies, something the colour of bruised silver — swayed in a breeze she couldn't feel on her face. "Tell me we're allowed in there," Rory whispered. Nyx's silhouette peeled away from the shadow of the nearest oak, reforming at her shoulder. "Allowed is a mortal word. The grove decides." "That's not an answer." "No," they agreed, voice brushing past her ear like a draft through a keyhole. "It isn't." Eva shifted her weight behind them, hand white-knuckled on the torch she hadn't yet turned on. "I can hear music." Rory tilted her head. She heard it too, threaded through the trees — a few notes of something stringed, then silence, then the notes again from a different direction, as if the player couldn't stay still. The Heartstone lay cold against her sternum. She touched it through her jumper and found it inert. Whatever this place was, it wasn't Hel. She stepped across the line between the oaks. The cold dropped away. So did the sound of Richmond Park — the distant hum of the A307, the chatter of roosting crows, the whine of a plane overhead. All of it simply stopped, like someone had closed a door behind her. Rory turned. The park was still there, framed by the standing stones, but muted, as though she were looking at it through dirty glass. "Christ," Eva breathed, stepping through after her. "That's — " "Don't finish that sentence here." Nyx slid between the trunks without disturbing a single blade of grass. "Names have weight in Fae places. Even His." The grove opened wider than it should have. Rory had paced the perimeter from outside — twelve, maybe fifteen metres across. Inside, the clearing rolled for what felt like half a field, dipping into a shallow bowl where a stream threaded between mossy stones. Light came from nowhere in particular. The sky overhead showed a sunset that hadn't been there a moment ago, rose and copper bleeding into a premature violet. "The sun's gone down," Eva said. "The sun hasn't done anything." Nyx crouched by the stream, trailing fingers that passed through the water as if it were smoke — or they were. "The grove shows you what hour suits it. Don't trust any clock you wear out of here." Rory walked toward the water. The wildflowers parted around her boots without being crushed, leaning back into place once she passed. She bent and set her palm flat against a patch of moss. It was warm. Warmer than her hand. Warmer than anything growing in a December park had any right to be. "Rory." Eva's voice pitched tight. "Look." Eva was pointing at the ground behind them. Rory's boots had pressed neat prints into the damp earth where she'd walked. Eva's trainers too — shallow, scuffed. Between them ran a third line of indentations, spaced for a tall stride, that stopped abruptly three steps in. As if the person leaving them had evaporated, or learned to stop touching the ground. "That'd be Isolde," Rory said, mouth drier than she wanted it to be. "She leaves no prints." "Then those aren't hers." Nyx's head came up. The violet of their eyes brightened, two slow pulses. "We're not alone. We were never going to be alone. Keep moving. Don't step off the path." "There's no path." "There is now." She looked down. A thread of white stones — no, white petals, pressed into the loam as neatly as cobbles — ran from her feet toward a stand of silver birch at the clearing's far edge. She was certain it hadn't been there a breath ago. Eva made a small, unhappy noise and fell into step at her elbow. They walked. The music came again, closer, a phrase of three descending notes, and Rory found herself humming the fourth before she could stop. Nyx's hand closed on her wrist — solid, cold as a stone pulled from a river. "Don't finish songs here either." "Right." She swallowed. "Noted." Past the birches, the grove opened onto something that made Eva stop breathing. Rory heard her don't-breathe and nearly did the same. A tree stood at the centre of a second, smaller ring — older than the oaks outside, bark pale as bone, branches black and spiralling inward to hold a single fruit. It might have been a pomegranate. It might have been a heart. It pulsed, softly, and when it pulsed, the grass underneath bent away from it in every direction, as if reluctant to be close. "That is not for us," Nyx said, very quietly. "Wasn't planning on picking it." "Good girl." A figure stood on the far side of the ring. She had not been there, and then she had — silver hair falling past her waist, lavender eyes lifting from the pale tree to the three of them. Isolde's bare feet made no impression in the moss. A smile caught the corner of her mouth and didn't quite reach the rest of her face. "You brought a Shade into my grove, Aurora Carter." "I brought a friend." "A pedant's distinction." Isolde's gaze slid to Nyx, lingered, moved on. "And you brought the mortal girl. Brave. Or thoughtless. It's often the same thing." "Oi," Eva said, because Eva had never in her life met a room she wouldn't argue with. Isolde's smile warmed a fraction. "Brave, then. Come closer, all of you. Not too close to the tree. It dreams, and I would rather it not dream of you." Rory took a step forward, then another. The petal-path had ended. Beneath her boots the moss gave like something breathing in its sleep. She felt the Heartstone warm — not the hot pulse of a Hel rift, but a low, considering glow, as though the pendant itself had woken up to take a look around. "You said come closer," Rory said. "That means you've got something to tell me." "I always have something to tell you." Isolde folded her hands. "The question, as ever, is whether you will listen."
