The mud was thick. It sucked at his boots with a wet, rhythmic sound, like a mouth chewing on a bone. Major Elias Thorne waded forward. The forest was wrong. The trees were too green. A vibrant, impossible green that hummed against the gray of the sky. He held his rifle loose in his hand. The weight of it was familiar. A comfort. He was hunting a signal. A text message that had been sent from inside the woods, then deleted, then sent again. Three times. Then silence.

His radio crackled. Static. Then a voice.

"Thorne. You are in the wrong sector."

It was his own voice.

Elias stopped. He stared at the tree line. The leaves were still. No wind. The green was bright enough to burn. He tapped his radio.

"Identify."

"Elias. You know who I am. Stop looking for it. It is not there."

The voice was calm. Detached. It sounded like him on a Tuesday afternoon, discussing logistics over cold coffee. It did not sound like a man in the mud, fighting for his life. Elias felt a chill that had nothing to do with the temperature. He walked toward the source. The mud pulled harder.

"Who is this?" he asked.

"Me. The other me. The one who stayed."

Elias raised his rifle. He aimed at the shadow of a man walking toward him. The man wore a uniform. It was clean. Pristine. It had no mud.

"Stay back," Elias said. His voice shook.

The man in the clean uniform stopped ten feet away. He did not have a weapon. He just stood there, hands in his pockets. He looked tired. Not like sleep-deprived tired. Like soul-tired.

"Put it down, Elias."

"You don't have it," Elias said. "You never had it."

"I have the knowledge. That is what you are hunting. The truth about the greenhouse."

The word hit Elias like a physical blow. The Greenhouse. It was a code name. A project. A facility buried deep in the Appalachian foothills. He had been assigned to secure it. To destroy it. But he had never seen it. He had only read the files. And the files were wrong. They described a place that did not exist. A place made of glass and light, where soldiers did not die but were *kept*.

"I know," the other Elias said. "I was there. I am still there."

Elias lowered the rifle. Just an inch. Curiosity is a poison. It tastes like sweet water in a desert.

"Come with me," the clean-uniform Elias said. "We need to go back. Before it changes."

"Why?"

"Because you are the key. And the lock is breaking."

They walked together. The forest changed. The trees grew taller. The green became a wall. It pressed in. The air smelled of ozone and wet earth. Elias felt a headache building behind his eyes. A splitting pain. He remembered his sister. Clara. She had died three years ago. A car accident. He had held her hand. He had watched the light go out of her eyes. He had carried her body.

"I remember her," Elias said.

"I remember her too," the other said. "But not like that."

"How?"

"She is here."

Elias stopped. The ground beneath him was soft. Moss. Deep, dark moss.

"Clara is in the Greenhouse," the other said.

"No," Elias said. "She is in a box. In the ground."

"Are you sure?"

Elias looked at his hands. They were muddy. He rubbed his thumb against his palm. He could feel the grit. He could feel the memory of the mud. But beneath the grit, there was something else. A smoothness. A coolness. Like glass.

He looked up. The sky was gone. It was replaced by a ceiling. A vast, curved ceiling of transparent material. Sunlight poured through it in shafts. It was beautiful. It was terrifying. They were inside a dome. A massive, glass dome.

"The Greenhouse," Elias whispered.

"It is not a building," the other said. "It is a state. A preservation. We fight here because we refuse to let go. You fight to destroy it. I fight to keep it."

"Why?"

"Because if we leave, she dies. Truly dies."

Elias felt the ground shift. The moss rippled. He saw a shape moving in the distance. A woman. She was walking toward them. She wore a white dress. Her hair was long and dark. She looked young.

"Clara?" Elias called out.

The woman turned. She smiled. It was a smile Elias had not seen in years. A smile of pure, unadulterated joy.

"Elias," she said. Her voice was clear. It cut through the hum of the glass.

Elias took a step forward. His rifle dropped into the moss. He did not care. He ran. He ran toward her. The other Elias did not move. He stood still, watching.

"Wait," the other said. "Do not touch her."

Elias ignored him. He was close now. He could see the dust on her cheek. He could see the tear tracks. He reached out. His hand closed around her shoulder.

It was solid.

It was cold.

It was not flesh.

Elias jerked his hand back. He looked at her. The smile was still there. But her eyes were empty. They were like lenses. They were like the glass of the dome.

"She is not real," Elias said. His voice was hollow.

"She is real," the other Elias said. "To you. That is all that matters."

Elias looked at the other man. He saw the truth then. The other Elias was not a ghost. He was not a hallucination. He was a mirror. A reflection of what Elias could become if he stayed. If he chose the comfort of the illusion over the pain of the reality.

"I have to leave," Elias said.

"You cannot," the other said. "The glass is closed."

Elias looked up. The dome was sealed. There were no doors. No windows. Just the endless, humming green.

"If I leave, she dies," Elias said.

"If you stay, you die," the other said. "Slowly. In the glass."

Elias looked at Clara. She was standing still. Waiting. She did not blink. She did not breathe.

He thought of the mud. He thought of the weight of his rifle. He thought of the cold coffee. He thought of the life he had before this. The life with the mistakes and the scars and the pain.

He picked up his rifle.

"Go," he said to the other Elias. "You can stay. You can keep her."

The other Elias smiled. It was a sad smile. A pitying smile.

"I cannot," he said. "I tried. I am the one who let go. I am the one who is free."

Elias raised his rifle. He aimed it at the glass ceiling. He aimed it at the light.

He fired.

The bullet hit the glass. It did not shatter. It did not crack. It simply disappeared. The glass absorbed it. Like water.

Elias fired again. And again. And again.

The glass did not break. But it changed. The green faded. The light dimmed. The hum stopped.

Clara began to fade. Her outline blurred. Her smile softened.

"I'm sorry," she said. Her voice was faint now. Like a radio signal losing strength.

Elias dropped the rifle. He fell to his knees. He reached for her one last time. His hand passed through her.

She was gone.

The dome was gone.

The forest was gone.

He was in the mud. The real mud. The cold, wet, sucking mud of the woods. The sky was gray. The trees were brown and leafless.

He was alone.

The radio crackled.

"Thorne. Status report."

It was his commander. A real voice. A harsh, demanding voice.

Elias sat in the mud. He looked at his hands. They were shaking. He looked at the ground. There was no glass. There was no greenhouse. There was only the dirt.

"I am here," Elias said.

"Target neutralized?"

Elias closed his eyes. He felt the weight of the silence. He felt the emptiness where Clara had been. He felt the pain. It was sharp. It was real.

"Yes," he said. "Target neutralized."

He stood up. He walked back to the edge of the woods. He did not look back. He did not look up. He walked toward the road. He walked toward the life that hurt. He walked toward the truth.

The mud sucked at his boots. It was the only sound.
