The boiler coughed. It was a wet, rattling sound, like an old man clearing phlegm in the dark.

I sat on the floor. The linoleum was cold. It was 1924, but it felt like forever. My friend, Elias, was dead. Or he was about to be. Or he had always been dead. The timeline was slippery. We were in the boiler room of the Whitmore textile mill. The walls were sweat. The air was thick with the smell of coal dust and rust.

"Listen," Elias said. His voice was thin. He was a small man. He had been my best friend since we were seven. Now we were twenty. We had done everything together. We had stolen apples. We had broken windows. We had learned how to fix things.

"I am listening," I said.

"Do you hear the hiss?"

"Yes."

"It is not steam."

My heart beat fast. I looked at the pipes. The main line was a giant black snake. It was coiled around the room. It was leaking. A thin white thread of vapor curled out of a joint. It looked like a ghost.

"Where?" I asked.

"Here." He pointed to the valve. The wheel was red. It was old. The paint was peeling. "It is going to burst. The pressure is too high. The regulator is broken."

I stood up. My knees popped. "Who broke it?"

"No one. It is just time. It is just wear. Things break. That is the rule."

"I can fix it."

"You cannot."

"Watch me."

I grabbed the wrench. It was heavy. It was iron. It had a notch in the handle. I remembered the notch. I had made it when I was twelve. We had been playing war. I had thrown it. It had hit the wall.

I put the wrench on the nut. I pulled. It did not move. I pulled harder. My arms shook. The metal bit into my palm.

"It is stuck," Elias said. He was sitting on a crate. He was watching me. He did not look afraid. He looked calm. He looked like he knew something I did not know.

"I will get it," I said.

"You are wasting time. The pressure is rising. Look at the gauge."

I looked. The needle was in the red zone. It was trembling. It was vibrating.

"I know," I said. "I am strong."

"You are not strong enough. You are not strong enough for this."

I pulled again. The nut turned a fraction of an inch. A spark flew. It was blue. It was small. It landed on my sleeve. I did not feel it.

"Why are you helping me?" I asked. I kept pulling.

"Because I am your friend."

"That is not an answer."

"Then what is an answer?"

"I don't know."

"The valve is corroded. It is fused. You cannot open it. If you force it, the pipe will tear. And then we will die."

"I will not die."

"You might. That is the risk. That is what we do. We take risks. We think we can control the machine. But the machine is bigger. The machine is time. Time eats everything."

I stopped pulling. I breathed. My breath was white in the cold air. "Elias, help me."

"I am helping. I am telling you the truth. That is how I help."

"I hate the truth."

"You should. It is a curse. It is a weight. You carry it. I carry it. We carry it. But we cannot put it down."

I looked at the gauge again. The needle was higher. It was almost at the top. The hiss was louder. It sounded like a scream. It sounded like a warning.

"I have an idea," I said.

"Go on."

"We close the intake. We stop the coal. We let it cool."

"That will take hours. We will not survive hours."

"Then what do we do?"

"We let it burst. But we do not let it burst here. We move it. We move the pressure to the secondary line. It is a weak line. It is designed to blow. It is a sacrifice. A controlled failure."

"That is insane."

"It is engineering."

"It is suicide."

"Only for the line. Not for us. If we time it right, we can open the vent before it hits the main room. We can redirect the steam to the outside. The alley. The alley is empty."

Elias stood up. He walked to the secondary valve. It was high up. It was on a ladder. The ladder was rusted. It looked weak.

"You have to hold the main valve," Elias said. "You have to keep it open. Just open. Let the pressure build. I will open the vent. I will wait for the hiss to change pitch. When it changes, I will open the vent. Then you close the main valve. Do you understand?"

"Yes."

"It is a game of timing. It is a game of nerves. If I am too early, the steam will flood the room. If I am too late, the main pipe will burst. And we will die."

"Yes," I said.

"Are you afraid?"

"Yes."

"Good. Fear keeps us sharp. Fear keeps us alive. But not too much fear. Too much fear makes you freeze. So do not freeze."

I gripped the main valve. I opened it. The pressure surged. The pipes groaned. The floor shook. Dust fell from the ceiling.

"Ready?" Elias called out. He was on the ladder. He looked small. He looked fragile.

"Ready."

"Open the vent."

I watched his hand. He reached for the wheel. He turned it. Slowly. Carefully.

The hiss changed. It was higher. It was sharper. It sounded like a needle. It sounded like a hair breaking.

"Now!" I yelled.

He turned the vent wide.

Steam exploded. It was not white. It was clear. It was a wall of nothing. It pushed us back. We fell. I hit the wall. My back ached. The steam filled the room. It was hot. It was scalding. I screamed. I could not breathe. The air was gone. The air was replaced by fire.

I coughed. I choked. I crawled. The steam was everywhere. It was in my eyes. It was in my nose. It was in my lungs. I could not see. I could not think. I only knew one thing. I had to close the main valve. I had to stop the flow.

I crawled to the valve. The metal was hot. It burned my hands. I did not care. I gripped the wheel. I turned it. It was stiff. It was fighting me. I turned it. I turned it. I turned it.

The hiss stopped.

Silence.

Total silence.

I lay on the floor. I gasped. I pulled the air into my lungs. It tasted like ash. It tasted like metal.

"Elias?" I called out.

No answer.

"Elias?"

No answer.

I stood up. My legs were weak. I walked to the vent. I looked out. The alley was empty. The steam was gone. It had dispersed. It had vanished. It was like it had never been there.

I looked back. Elias was on the floor. He was near the ladder. He was still. He was not moving.

I ran to him. I knelt. I touched his face. It was cold. It was pale. He was smiling. He was smiling.

"Elias," I said. "Elias, wake up."

He did not wake up.

I looked at his hands. They were red. They were burned. He had held the wheel. He had held it until the end. He had done his part. He had given his life to save mine.

I sat next to him. I held his hand. It was cold. It was dead.

I looked at the boiler. It was quiet. It was still. It was safe. The machine was safe. The mill was safe. The town was safe.

But I was not safe.

I was alone.

I thought about the valve. I thought about the pressure. I thought about the time. I thought about the wear. Everything wears. Everything breaks. Everything dies.

I stood up. I walked to the door. I opened it. The light from the hallway was bright. It was harsh. It was real.

I stepped out. The hallway was long. It was empty. The walls were green. The floor was wood.

I walked. I did not look back. I knew I could not look back. If I looked back, I would see him. And I would have to remember. And remembering was the curse.

I reached the top of the stairs. I went outside. The air was cold. It was crisp. It was clean.

I walked to the edge of the town. I looked at the river. The water was dark. It was moving. It was always moving.

I saw a mist. It was pale. It was thin. It was rising from the water. It was drifting toward the town. It was drifting toward the mill.

I watched it. I watched it cover the buildings. I watched it cover the streets. I watched it cover the people.

It was beautiful.

It was terrifying.

I understood now. Elias had not just saved my life. He had shown me the truth. The truth is that we are small. We are weak. We are temporary. But we can still choose. We can still act. We can still love.

I put my hands in my pockets. I walked home.

The mist followed me. It was in my eyes. It was in my mind. It would always be there.

I was twenty years old. I was an engineer. I was a man.

I was alone.

But I was alive.

And that was enough.

That was more than enough.

The mist settled. The town slept. The boiler rested.

And I waited.

I waited for the next thing to break.

I waited for the next time to pass.

I waited for the next friend to die.

I waited for the next curse to arrive.

I waited.

I waited.

I waited.
