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 arch sat where no arch should have been, stitched into the hollow between two roots of an oak older than any king Aurora could name. From this side, it looked like a crack in the air. From the other, Isolde had promised, it would look like a door. "After me," Isolde said, and stepped through without leaving a mark on the moss. Aurora's hand went to the pendant at her throat before she'd told it to. The stone hummed against her collarbone, warmer than her skin, pulsing in a rhythm that wasn't her heartbeat. "It's awake," she murmured. "So is something else." Nyx flowed past her, less a body than a suggestion of one, their violet eyes the only fixed point in the dark. "Don't dawdle, Carter. The Veil doesn't like indecision." She drew the Fae blade from her belt. The moonsilver caught a light that wasn't there and threw it back doubled. She breathed out, watched the breath turn to frost, and stepped through. The world rearranged her. For a heartbeat she was nowhere — a pressure in her ears, a taste of iron on the tongue, the sense of being looked at by something that had forgotten what eyes were for. Then her boot came down on stone, and the air changed. It smelled like rain on old books. Like honey left in a copper bowl for a hundred years. Like nothing she had ever filed under a name. "Oh," she said, because nothing else fit. They stood at the head of a causeway that stretched into a cavern too vast for its own walls. The ceiling, if there was one, hid inside a slow drift of lights — not stars, she realised, but motes that moved with purpose, wheeling in long patient arcs the way starlings did over the Severn at dusk. Each one cast a thread of its glow onto the flagstones below, so that the path ahead looked stitched together from threads of pale gold. To either side of the causeway, the ground fell away into something that might have been water or might have been sky. When Aurora looked down, she saw clouds. When she looked again, she saw her own face, warped, older, not quite hers. "Don't," Isolde said without turning. "It shows you what it thinks you want. It is rarely correct." Aurora dragged her eyes back to the path. "What is this place?" "A waiting room." Isolde's voice was softer here, less riddle-weighted, as if the grove accent of her speech loosened in her mother's country. "Built before the Veil. Abandoned when the Veil was set. Older than my mother. Older than her mother." "It has a name?" "Many. None in a language your tongue will manage." Nyx drifted ahead, solidifying and thinning by turns, testing the light. Where the motes passed through them they split and re-formed on the other side, the way water parts around a stone. "It recognises me," they said, and there was something in their whisper Aurora hadn't heard before. Not fear. Closer to homesickness. "This is the sort of dark I was made in." "Stay on the stones," Isolde warned. "Anything that isn't the path is a question you cannot afford to answer." They walked. The causeway sloped gently down. Aurora counted her steps for the first hundred, then gave up; the numbers felt untrustworthy here, as if the air might lend an extra one when she wasn't looking. The pendant's pulse had settled into a slow, steady heat — not the panicked flutter it gave near a rift, but something pleased, like a cat that had found a sunbeam. "It likes this place," she said. "Of course it does." Isolde did not explain. At the foot of the slope, the path widened into a round plaza ringed by pillars. The pillars were carved — Aurora ran her gloved fingers over one and felt the grooves shift beneath her touch, rearranging like ants under a leaf. When she lifted her hand, the pattern that had been there a moment ago was different. A face, maybe. A word. Gone before she could name it. "They're rewriting themselves." "They're remembering." Isolde had her palm flat against a pillar of her own, her eyes closed, her lips moving in a soundless shape. "Slowly. They've been asleep a long time." Nyx had drifted to the centre of the plaza, where a low basin of black glass sat empty. They hovered a hand over it. Frost bloomed across the rim in the shape of letters Aurora could almost read and then couldn't. "There's water in here," Nyx said. "I can't see it. I can feel it pulling." "Don't drink it," Isolde and Aurora said together. Nyx made a sound that might have been a laugh. "I don't drink, Carter." Aurora edged closer. The basin was dry to her eyes — polished, unclouded, a perfect black. And yet when she leaned over it she felt the unmistakable tug of depth, as if she were looking off the edge of a pier in the dark. The Fae blade in her hand hummed. Not the cold-singing she'd grown used to on Earth. A different note, higher, cleaner, the way a struck bell sounds to the bell. "It knows you, too," Isolde said, and her pale eyes were on the blade. "It was forged from stone carved out of a place like this. Hush, little sister. You're home." The dagger went warm in Aurora's grip for the first time since she'd owned it. The surprise of it made her laugh, short and startled, and the laugh travelled up into the wheeling motes above and came back down scattered into smaller sounds, like coins dropped on marble. Somewhere far off, something answered — a chime, a bell, a voice clearing its throat. Aurora's shoulders went up. "Please tell me that was the architecture." "The architecture is listening," Isolde said. "Something else has answered." Nyx drew back from the basin. Their violet eyes had narrowed to slits. "Company," they whispered. "Down the second passage. Moving slow. Not toward us yet." Aurora steadied the blade in front of her. Her pulse beat against the Heartstone; the Heartstone beat back, warmer now, almost eager. She could hear, very faintly, the soft scuff of something that was not a foot on stone that was not quite stone. "How long do we have?" she asked. Isolde tilted her head, listening to a register Aurora couldn't reach. Her silver hair moved though there was no wind. "Long enough," she said, "to be afraid properly. Come. There is something here I was sent to show you."
