Chapter 2 THE COST OF A HEARTBEAT

The Thresher didn’t move like a man. He moved like a shadow cast by a flickering flame.

Kaelen’s breath hitched. The gold light under his skin wasn't just glowing anymore; it was vibrating, humming against his ribs like a trapped hornet.

"Kill the boy!" one of the hunters screamed.

Three men rushed in from the left. They were professionals, moving in a tight triangle with jagged spears leveled at Kaelen’s chest. A day ago, Kaelen would have fallen to his knees and begged for mercy.

But the Spark wasn't asking for mercy. It was asking for a room.

As the first spear tip grazed his tunic, Kaelen didn’t think. He reacted. His hand shot out, grabbing the shaft of the spear. The wood disintegrated into white ash the moment he touched it. He stepped into the hunter’s space and shoved his palm against the man’s leather armor.

Boom.

The hunter didn't just fall. He vanished into a cloud of red mist and golden sparks. The two men behind him were tossed through a storefront window, their screams cut short by the sound of shattering glass.

Kaelen stared at his shaking hands. "What did I just do?"

"You used a week’s worth of life in a second," a voice hissed from the rooftops.

Kaelen looked up. A woman stood on the edge of a crumbling chimney. She had silver-threaded hair and eyes that looked like they had seen the end of the world. She held a small, glass device that was clicking rapidly.

"Who are you?" Kaelen shouted.

"Someone who wants you to keep breathing," she said. She jumped down, landing softly in the dirt between Kaelen and the Thresher. She didn't look back at Kaelen. Her focus was entirely on the man in the long coat. "Thresher. This one is mine."

The Thresher wiped blood from his lip and chuckled. "A Spark-Tender? You’re a long way from the hospitals, Elara. Since when do you protect the cattle?"

"Since the cattle started carrying the King’s Ransom," Elara replied. She reached into her belt and pulled out a metal sphere. "Run, Scav. If you stay here, the Thresher will peel that Spark out of you while you’re still screaming."

Kaelen didn't need to be told twice. He turned and bolted down the alleyway.

His legs felt light. Too light. Every step he took covered ten feet. He was moving faster than a horse, blurring past the ruins of the Sun City. But the faster he ran, the hotter his chest became.

167 hours and 50 minutes. The number appeared in his mind as clearly as if it were carved on a wall. He was burning his life away just to escape.

He ducked into the basement of a collapsed tavern and collapsed behind a pile of rotting barrels. He clutched his chest, gasping for air. The gold veins had reached his neck now. He could see them in a puddle of dirty water on the floor.

"I have to get rid of it," he whispered. "I have to find a way to pull it out."

"You can't," a voice said from the shadows.

Kaelen jumped, his hands glowing with a dangerous light. It was the woman with the silver hair. Elara. She had followed him, or perhaps she had known where he was going.

"The Spark is part of your blood now," she said, stepping into the dim light. She looked at him with a mix of pity and hunger. "If I try to pull it out here, your heart will stop. You’re a battery, Kaelen. And you’re leaking."

"How do you know my name?"

"I know a lot of things. I know your father was a Scav, too. I know you’ve spent your life trying to be invisible." She walked closer, her eyes locked on the gold pulse in his throat. "But you’re the most visible thing in Oros now. Every Hunter, every King, and every God is coming for you."

"Why are you helping me?" Kaelen asked, his voice breaking. "You’re a Spark-Tender. You work for the system."

Elara’s expression darkened. She pulled back her sleeve, revealing a series of jagged scars on her arm, the kind made by divine shackles. "I don’t work for them anymore. I want to burn the Silent Forge to the ground. And you... You’re the fire I’ve been waiting for."

Kaelen shook his head. "I don't want to be a hero. I just want to live."

"Then listen to me," she said, grabbing his shoulders. Her touch was cold, grounding the heat in his body. "The Thresher is still coming. He doesn't lose a scent. There is only one place where we can survive this. The Silent Forge. They have a machine that can save you."

"A cure?" Kaelen’s heart leaped.

"A way out," she corrected.

Suddenly, the roof of the basement exploded.

A black iron hook smashed through the ceiling, narrowly missing Kaelen’s head. The Thresher dropped through the hole, landing heavily on the floor. He wasn't smiling anymore. His coat was shredded, and his eyes were glowing with a borrowed, stolen light.

He didn't look at Elara. He looked straight at Kaelen.

"The girl is lying to you, boy," the Thresher growled, raising his black blade. "The Forge doesn't save people. It harvests them. But don't worry. I’m not here for the Forge."

The Thresher stepped forward, and the air around him turned cold.

"I'm here for revenge," the Thresher whispered. "The man who gave you that Spark killed my brother. Since I can't kill a dead god... I’m going to make his chosen vessel suffer for eternity."

The Thresher lunged, but he didn't aim for Kaelen’s heart. He aimed for his legs.

"Kaelen, move!" Elara screamed.

But Kaelen didn't move. A new memory had just flashed in his mind. A memory of the Thresher standing over a small house in the slums. A house Kaelen recognized.

Kaelen saw the Thresher setting a fire. He heard a woman’s scream from inside. His mother’s scream.

The Spark didn't just give Kaelen power. It gave him the truth.

"It was you," Kaelen said, his voice dropping to a terrifying, hollow growl. The gold light in his eyes turned a blood red. "The fire ten years ago. It wasn't an accident."

The Thresher paused, a cruel grin spreading across his face. "I wondered if you'd remember, Scav. I didn't just kill a god today. I’m finishing a job I started a long time ago."

Kaelen didn't feel afraid anymore. The fear was gone, replaced by a white-hot wall of hate. He didn't care about the seven days. He didn't care about the Forge.

He lunged at the man who had ruined his life, his hands glowing like twin suns.

"I’m not running anymore!" Kaelen roared.

As their powers collided, the entire building began to groan and collapse. But through the dust, Kaelen saw something that made his blood turn to ice.

Behind the Thresher, standing in the shadows of the hole in the ceiling, was another figure. A man who looked exactly like Kaelen, but with eyes made of pure, empty darkness.

"Kill him, brother," the shadow whispered. "Give in to the Spark."
