The culvert spit them out under reeds that hissed in the wind. The world beyond was gray and wet. The sound of engines dulled to a far hum, like a storm moving to another valley but not gone. Ari wiped mud from her brother's cheek with the heel of her hand. It left a darker smear. He did not complain. His eyes were too big in his small face.x
"We keep the reeds on our right," Kael said. His voice was low and pared down to need. "There's a slope ahead where the bank gives. After that the trees."
Her father looked back once toward the hidden square. Smoke rose in a column that leaned and tore as the wind took it. He set his jaw. "Move."
They moved. The ground sucked at their boots. Reeds rattled like thin bones. Every few steps a bird burst up and skimmed the tops, wings cutting a path the wind closed again. Ari kept one hand on her brother's back and one on her chest, pressing the heat there flat. The shard's pulse had settled from a frantic hammer to a hard steady beat. She could live with steady.
They reached the place Kael had named. The bank had slumped into a slope of caked mud and tangled roots. Footprints scarred it. Some fresh. Some already watered into shapeless dark. Kael climbed first, planting his spear and testing each hold before giving the word. Ari's brother went next. He slipped halfway and yelped. Ari caught his wrist and shoved his foot back onto the root. Her heart jumped so hard the heat under her sternum flared in answer.
"Three points," she said. "Say it."
"Three points," he muttered, breathless and angry with himself, and he climbed the rest without slipping.
Ari followed, then her father. At the top a fringe of trees held a strip of higher ground that smelled of leaf and wet earth. The sound of the square dropped another notch. The wind shifted. For a breath they could hear nothing but their own breaths and the reeds talking to themselves.
"Good," Kael said. "We cut across the ridge and..."
The wind turned again. A crack ran along it from the fields like a whip over water. Then another. Then the chemical howl of a flare. The sky brightened by a shade and Ari felt heat on her cheek that did not come from the shard.
"Down," her father said. "Stay low and do not show your backs."
They crouched behind a fallen trunk. Between the branches Ari could see the bean rows. A line of orange crawled along them, slow and greedy. The fire ate the stalks and left black ribs behind. Smoke rolled flat over the ground. People moved in it like shadows that forgot what shape they had started with. Drones dipped. The red eyes scanned the smoke where bodies hid. Shots chopped the air. The fire answered with a sound like dry paper being crumpled forever.
"They're flushing the lanes," Kael said. He sounded sick.
Her brother pressed closer. "Will it reach us."
"Not if we keep the wind to our cheek," Ari said. She put her palm against his hair and felt the heat there. He was burning with fear and she was too proud to lie about it even to herself.
"We can't go back," her father said. "We can't go through. We go along." He pointed east along the ridge. "The canal bends there. The old quarry road crosses. Culverts run under it. We can cut through before they net the far side."
Kael nodded like he had already walked those steps in his head twice. "Move."
They ran bent. The ground under the trees was laced with old roots. Their boots found them without looking because the body can learn a path faster than eyes when it must. Twice they dropped flat as drones clicked low overhead. Each time Ari pressed her brother's face into the wet leaf mold until he stopped shaking. Each time the shard in her chest stirred like a thing trying to sit up. She told it no without words and kept moving.
Shouts rose behind them. The tone changed. Not the bark of orders. The raw sound people make when something breaks close. Ari did not turn. She did not need to see to know what was happening. Fire does not care about uniforms. Fire eats stories and paper and names at the same speed.
They reached the quarry road. The ditch there was wide and half choked with bush. The roadbed had been raised on a bank of stone and culvert arches cut through it at intervals. The nearest sat in shadow. Water hissed thin through it. A set of boot prints tracked dark into the mouth and came out on the far side a long way off. Not recent. Recent prints end in panic.
Kael peered into the shadow and tested the lip with his spear. He nodded. "Clear. Narrow."
Her father gripped Ari's shoulder. His hand shook once. "I'll take the rear. If they see us, I delay."
"No," Ari said. The word came too fast. She breathed and made it calm. "We go together."
He looked at her with the same hard soft eyes he had used when she was little and refused to come out of the rain. "Together then," he said.
They slid into the culvert one by one. The air inside was cool and old. The water ran ankle deep and smelled of rust. Ari bent low and shuffled with her hand on the wall. The stone was slick with long slime that came away in threads. The slime stuck to her fingers and made her want to gag. She swallowed it and kept her breaths shallow.
Halfway through the tunnel the road above shook. Boots pounded in time. Light speared the culvert mouth and turned the water into a strip of white. A drone's red eye hovered at the other end like a coin held above a bowl.
Her brother froze. He pressed back against Ari and whispered her name like an apology. The shard under her sternum flared. Heat spread through her rib cage and down her arms until her skin prickled. She curled around the heat with her shoulders hunched, afraid the glow would show.
The boots passed. The light moved on. The red eye drifted away as if the culvert bored it. Ari let out the breath she had forgotten to release. Her whole body shook. The shaking felt like weakness and also like proof that she was still here.
They spilled out the far mouth into a cut in the bank. The wind hit their faces clean. The smoke smell thinned to memory. The slope up was steeper and crumbly with loose rock. Kael went first. Ari pushed her brother behind him. Their father came last again. His breath sounded wrong. Shorter. Hotter. Ari turned to look. He waved her forward and forced a grin that did not belong on his face.
"Almost," he said.
They topped the bank and dropped into a stand of stunted trees whose bark peeled in long strips. The leaves here were like little spades. A trickle of water ran over flat stone. Ari cupped her hands and drank without caring about grit. Her brother drank too fast and coughed. Kael filled his palms and offered them to Ari's father. He shook his head. He stared back the way they had come.
"We have to keep moving," Kael said. "They'll sweep this corridor."
Ari's father didn't answer right away. He walked to the edge of the rise and looked over the fields. The fire had reached the outer rows and was climbing the ridge like a slow animal. At the edge of the smoke a line of soldiers pushed families toward a pen of carts. Drones circled overhead. The officer's voice bled across the distance in flat iron tones. Ari could not make out the words. She didn't need to.
Her father's shoulders sank. He reached into his pocket and took out the little folded scarf Ari had tied that morning. He held it a breath and then tucked it back. When he turned his face to them, it had the look of a wall that knows it will be leaned on.
"We head for the old fissure," he said. "The one that breathes cold. They won't risk the deep shafts in the first sweep."
Kael's mouth tightened. "It's unstable."
"So is the valley," her father said. "Pick a danger you know the steps for."
They threaded the ridge until the ground broke into a scatter of sinkholes and seams. Cold air seeped from a crack that ran like a knife wound through the limestone. It smelled of wet stone and something sour. The shard pulsed hard at the smell, a deep bass thud that Ari felt in her teeth. The hum was not warning. It was recognition.
Her brother wrinkled his nose. "It stinks."
"Bad smells don't kill," Ari said. "Noise does."
Kael knelt and pried at the edge of the fissure with his spear butt. The stone flaked away like old paint. The gap widened enough for a human shoulder. "Sideways," he said. "Face in. Don't look down."
Her father put a hand on Ari's cheek. His palm was rough and warm. He looked like he wanted to say something that would make a story of this moment so it would fit into their minds. He did not lie. He did not make it pretty. He kissed her hair instead and helped the boy into the crack.
Her brother shoved himself into the dark with small grunts. The stone scraped his coat. Dust filled the narrow space. He disappeared like a flame pinched between fingers. Ari followed, chest tight, one arm raised to keep her shoulder from jamming. The shard flared hot as it slid between the rock faces. It fit her like a lamp fits a niche. She tried not to think about how right the mountain felt pressing against a thing that now lived under her skin.
Behind her came Kael's boots. Behind him came her father. The light narrowed to a skin of gray and then thinned to nothing. Ari listened to the sound of her brother's shoes scraping ahead and matched her breaths to that rhythm. When the crack widened, she could finally pull her shoulder in and turn her head.
The fissure opened into a crawlspace that sloped down. Stale air brushed her face like the breath of a sleeping animal. Water dripped somewhere far off, slow and in time. The sound held its own patience. Ari felt her own breath ease into it. The shard settled to the same count, as if a metronome had finally found its mark.
She reached for her brother and touched his ankle. "Still with me."
"I'm here," he whispered. His voice shook. He tried to steady it by making it quiet.
"Good," Ari said. "We keep going until we find space big enough to stand. Then we drink. Then we decide."
They slid and crawled until the ceiling lifted. The chamber they entered had ribs of stone that rose from floor to roof. A thin sheet of water fell from a notch and collected in a shallow basin. Symbols ringed the rim. Spirals. Lines. Tiny dots pressed at their centers as if left by a hot needle. The same marks from the mine face, only more deliberate and less tired.
Her brother knelt and cupped his hands. Ari caught his wrists. "Wait." She sniffed. No rot. No sour. She dipped a finger and touched the drop to her tongue. Cold. Clean. She drank first and let the water beat against the roof of her mouth like a tiny drum. The sound made the shard answer with a warm pulse. She passed the basin to her brother's hands. He drank and shivered and smiled with his eyes closed.
Kael drank next. Then her father. When he set the water down, he swayed. Ari stepped in close. "Sit."
"I'm fine," he said.
"Sit anyway," she said. He sat. He hated the order and loved the relief.
From deep in the stone came a thud. Not collapse. A closing. Air shifted. Dust drifted from a crack and twisted in a thin column. Ari felt the change in the way the shard lifted in her chest like a bird that had heard a call too faint for human ears.
Kael looked up, face white. "They're sealing the upper cuts."
Her father rubbed his forehead with the heel of his hand. "They'll turn the valley into a pen and walk it until nothing moves that they did not put there."
Silence lay heavy. Only the water kept its count. Ari sat by her father and set her shoulder against his arm. He leaned into it without meaning to.
"What now," her brother asked. He had finished shaking and started thinking again. That was worse.
"Now we rest," Ari said. "Then we move deeper. We find where the cold air leads."
Kael crouched by the carved basin. He traced a spiral without touching it. "This is older than our stories."
Her father breathed out slow. "Old stories built on a new fire. That is what we are standing in."
Ari lifted her hand and hovered it over one of the tiny pressed dots. Heat rose in her chest as if the shard had shifted closer to her palm. She lowered her finger and touched the mark. Gold light walked the spiral once and went out.
Her brother's breath hitched. "Did you see..."
"I saw," Ari said. She tried to make her voice calm. It came out soft instead. "Don't be afraid. It's only a sign saying the stone is listening."
"What happens if you press all of them," he asked.
"Then the stone gets bored," Ari said. He almost laughed. She wanted him to. She would trade a day of breath to hear him laugh full.
They rested. The water licked the basin lip. The air cooled their sweat until shivers chased the heat out and left them clean. A distant rumble moved through the rock like a large animal shifting its weight. Ari could not tell if it came from the Empire above or the mountain itself remembering old motions. Either way, the sound did not ask permission.
Her father closed his eyes and sat very still. After a long time he said, without opening them, "If we do not come back, your mother will follow our trail until she finds its end."
"We will come back," Ari said. She put both hands on his arm and held on. "I will make it so."
He smiled the small tired smile that meant he believed her even if the world did not. "I know you will try," he said.
They gathered themselves. The tunnel that led out of the chamber did not rise or fall at first. It chose the easiest path like water. The marks on the wall kept appearing and then vanishing again, as if someone had once tried to leave a map and then decided the map should be a riddle.
The ground trembled once more. Dust fell in a soft veil. Somewhere far behind, rock gave a deep groan. The sound went on and on and then stopped with a thump that Ari felt in her knees.
"Collapse," Kael whispered.
"Not ours," her father said. He listened the way miners do when the mountain speaks. "But close."
The shard warmed fast under Ari's sternum. Her skin prickled. She slowed. The warmth was not warning. It was pulling. The air turned colder by a breath. The tunnel bent. Light glowed ahead, not white, not blue. Gold. A pulse that kept time with her heart until she could not tell which one had started the count.
Her father touched her elbow. "Ari," he said.
"I know," she whispered. Her mouth had gone dry. "I feel it."
Kael lifted his spear. He did not point it. He held it across his body like a bar to catch a fall that had not yet begun. "We should turn back," he said.
"We cannot," Ari said, and the truth of it was simple as breath. "It is calling me."
Her brother grabbed her sleeve. "Don't leave me."
"I won't," she said. "Not for anything."
They stepped into the light and the chamber opened around them like a held breath finally let go. At the center stood an altar of black stone, edges sharp as the day it was cut. On it lay a crystal the color of sun through amber. It pulsed. When it brightened, the walls showed the ghosts of carvings. When it dimmed, those ghosts vanished. The air smelled like frost and summer at the same time.
Ari did not choose to walk. Her feet did it. The shard in her chest answered the one on the altar with a heavy quickening. It was not joy. It was not fear. It was the kind of recognition that makes knees weak.
Her father reached for her and stopped. He had always trusted her with tools and with knots. He made the same choice now. He let her walk. Kael did not. He stepped in front of her with his spear across his chest, eyes wide.
"Don't," he said. "You don't know what it will do."
"I know what will happen if I turn away," Ari said. "It will call me again. It will find me in my sleep. Better to answer where I can see."
He searched her face like there was a safer version of her hidden underneath and he could pick it by looking hard enough. Then he stepped aside. He hated it. He did it anyway.
Ari climbed the three steps to the altar. Her hands shook. She pressed them flat against her thighs until they stilled. She reached. The shard under her skin rose to meet the one above the stone.
Her brother made a sound that scraped his throat raw. "Ari, please."
She looked back. "I'm still here," she said. "Whatever happens, you hold my hand when it's done."
He nodded. He was crying and trying not to make noise about it.
Ari touched the crystal. Heat poured through her palm and ran up her arm into her chest where it met the other heat and the two became one fire. She cried out, not from pain only, but from the shock of how right the weight felt. The chamber shook. Dust rose in fountains. The altar cracked down the middle with a sound like ice breaking in spring.
The world ran to dust at the edges. Stone became powder and lifted like smoke. The gold flared and swallowed dark. The last thing Ari saw was her father's face turned up to hers, eyes fierce and full, and Kael's mouth shaping her name like a vow he had not made yet.
The fire in the fields had been only a beginning. The binding would tear the day open and make a new one inside it.
