The transition from coal to gas was not just a mechanical shift. It was an awakening. The air in the Iron District began to clear for the first time in a generation, the heavy soot falling away to reveal the raw, gray stone of the buildings. Inside the forge, the heat was a constant, shimmering roar. The blue flames licked at the vats with a ferocity that made the old coal fires look like flickering candles.
Lyra stood at the center of the foundry floor, her sleeves rolled up and her face streaked with the grease of the gas lines. She was watching the final pour of the ninth ton. The steel was perfect. It had a luster and a strength that exceeded the Coalition's specifications.
"We are ahead of schedule," Miller shouted over the hiss of the cooling racks. He sounded jubilant, his exhaustion replaced by a frantic, nervous energy. "If the gas holds, we will have the tenth ton ready by tomorrow evening. We will beat the deadline with three days to spare."
"The gas will hold," Caelan said, checking the pressure gauges on the main intake. "The pockets under the flats are vast. We could run the entire city on this for a year before we see a drop in pressure."
Lyra did not join in their celebration. She was looking at the harbor through the high, arched windows of the forge. The Talon was no longer docked at the main pier. It had moved to a position directly across from the gas works, its heavy cannons angled toward the shore.
"They know," Lyra said, her voice cutting through the noise.
Miller and Caelan stopped. They followed her gaze to the water. The silhouette of the ironclad was a dark, menacing shape against the setting sun.
"They can't know," Caelan argued. "We laid the pipes under the cover of the mist. We didn't leave a single scrap of iron on the surface."
"They don't need to see the pipes to see the smoke," Lyra said, pointing to the chimneys. "The black clouds stopped yesterday. The Coalition knows we aren't burning their coal. Sterling is a diplomat, but he is also a strategist. He knows that if we don't need their fuel, we don't need their protection."
A messenger burst through the heavy doors of the foundry, his chest heaving. It was one of the young boys Silas used for the neighborhood watch.
"Miss Belrose!" the boy cried. "The Coalition is sending a boarding party! Not to the pier, but to the shale flats! They have a squad of sappers with them!"
"They are going to cap the wells," Caelan hissed, reaching for his heavy hammer. "If they shut down the gas now, the furnaces will stall. We will lose the heat, and the metal in the vats will solidify. It will take weeks to clear the slag."
"They won't cap the wells," Lyra said, her mind moving with the speed of a falling blade. "They want the gas for themselves. They realize that Oakhaven is more valuable as a fuel station than as a steel mill."
She turned to Miller. "Keep the pour going. Do not let the temperature drop by a single degree. Use the emergency reserves if you have to."
"What are you going to do?" Miller asked.
"I am going to remind them that the earth belongs to the people who walk on it," Lyra said.
She grabbed a heavy leather coat and headed for the door. Silas met her in the courtyard, a group of thirty workers behind him. They were armed with nothing but wrenches and heavy chains, but their faces were set in a mask of defiance.
"They are landing at the north beach," Silas said. "We can cut them off at the old refinery, but they have rifles, Lyra. We can't win a shootout with a line of marines."
"We don't need a shootout," Lyra said. "We have the pressure."
They reached the shale flats just as the Coalition launch hit the sand. A dozen marines stepped out, led by a man in a black uniform. He carried a set of heavy iron caps and a toolkit. They moved toward the primary valve with the confidence of men who expected no resistance.
Lyra stepped out from behind a jagged rock, her hands raised but her eyes cold.
"That is a restricted area, Lieutenant," Lyra called out.
The marine officer stopped, his hand going to the hilt of his saber. "By order of the Southern Coalition, these resources are being placed under military guard to prevent further sabotage. Move aside, or you will be detained."
"You are the ones committing the sabotage," Lyra said. "You sent us bad coal to force a crisis, and now you want to steal the air from under our feet. I am telling you now, if you touch that valve, you won't be detaining anyone. You will be flying."
The Lieutenant sneered. "With what? Your wrenches? Move the girl!"
As the marines stepped forward, Lyra signaled to Caelan, who was hidden in the valve pit. He didn't close the valve. He opened the bypass.
A deafening roar erupted from the earth. A geyser of pure, invisible gas shot fifty feet into the air, the pressure so intense it created a localized windstorm that knocked the marines off their feet. The sand hissed and swirled in a violent vortex.
"The air is saturated!" Lyra shouted over the roar. "The smallest spark from a rifle or a boot-heel will turn this entire flat into a sun! If you want to take the gas, go ahead! But you will be the first things to burn!"
The marines froze. The Lieutenant looked at the shimmering air around him, his face pale. He knew she wasn't bluffing. The scent of the gas was overwhelming, a thick, metallic smell that promised a swift and fiery end.
"You're crazy," the Lieutenant whispered, his voice trembling. "You'd blow yourself up just to stop us?"
"I'd do a lot more than that to keep you out of my home," Lyra said.
She held up a small, flint-striker. She didn't strike it, but her thumb was poised on the steel.
The silence that followed was broken only by the roar of the bypass. For a long minute, the fate of Oakhaven hung on the tension of a single spring. Then, the Lieutenant barked a command. The marines backed away, retreating toward the launch without looking back.
As the boat pulled away into the darkness, Caelan closed the bypass. The roar faded to a hiss, then to silence.
Lyra slumped against a rock, her hand shaking as she tucked the striker away.
"That was too close," Silas said, stepping up to her. "What if they hadn't blinked?"
"Then we would have been a very bright light for a very short time," Lyra said.
She looked toward the *Talon*. The ship was still there, its guns still aimed at the shore. They had won the flats, but they had revealed their hand. The Coalition knew they were independent now. And in the world of the South, independence was the one thing that could never be forgiven.
"We have three days," Lyra said. "And the whole world is watching."
