The mud is cold. It bites into your boots. You are running. Your lungs burn. The air tastes of iron and wet stone. Behind you, the thing screams. It is not a scream of flesh. It is a scream of void. You know this. You have always known this.

Your name is not important. Your rank is not important. You are a soldier. You are a man. You are being hunted.

The forest is dense. The trees are black ribbons against a gray sky. There is no sun. There is no moon. There is only the light of the thing. It pulses. It is red. It is wrong.

You trip over a root. You hit the ground. The pain is sharp. Real. Good. You need to feel pain. Pain keeps you human. Pain keeps you from becoming like it.

You push yourself up. You check your weapon. It is a rifle. It is empty. You have no bullets. You have no grenades. You have only your hands. And your will.

The thing is close now. You can hear its breathing. It sounds like wind through a broken chimney. It sounds like a dying god.

You see a structure ahead. It is small. It is made of stone. It looks like a watchtower. Or a prison. It is old. The moss is thick on the walls. The door is open.

You run toward it. Your legs are shaking. Your vision is blurring. You are tired. So tired. You want to stop. You want to lie down in the mud and sleep. But you cannot. If you stop, you die. If you die, you become part of the thing.

You reach the door. You look back. The thing is there. It has no face. It is a shape of shadow and fire. It is coming for you.

You enter the structure. The air inside is stale. It smells of dust and old blood. You slam the door. You brace your shoulder against it.

The thing hits the door. Once. Twice. Three times. The wood shakes. The stone walls groan.

You slide down the door. You sit on the cold floor. You close your eyes. You breathe. In. Out. In. Out.

You are not alone.

A voice comes from the corner. It is quiet. It is dry.

"Did you find it?"

You open your eyes. A man is sitting in the shadows. He is old. His hair is white. He is wearing a coat that is too thin. He is holding a glass of water. The water is clear. It glints in the dim light.

"I don't know who you are," you say. Your voice is rough.

"I am the keeper," he says. "I have waited for you. For a long time."

"Why?"

"Because you are the last one. The only one who remembers."

You frown. You do not remember. You do not know what he means.

"Who are you?" you ask.

"I was a soldier. Like you. I was a hunter. Like you. But I made a mistake. I let it in."

The thing hits the door again. The wood splinters. A piece flies into the room. It hits the floor.

"Stay here," the old man says. "Let it take me. It wants me. It thinks I am the key."

"No," you say. "I will not let you die."

"You must."

"I am a soldier. I protect."

"You are a prisoner. Look at your hands."

You look at your hands. They are trembling. They are stained with mud. And something else. Something dark. It is not blood. It is ink. Or oil. It is spreading from your wrists to your elbows.

You feel a coldness. It is inside your bones. It is the cold of the void.

"I feel it," you say. "It is here."

"Yes. It has been with you since you were born. It is in your blood. It is in your mind. You are not a hunter. You are a vessel."

You shake your head. "No. I am real. I am me."

"Who are you?" the old man asks. "What is your name?"

You try to remember. You search your mind. You find nothing. Just fog. Just silence.

"I am... I am..."

"You are the threshold," he says. "The place where the world ends and the void begins. You are the door."

The door breaks. The wood explodes outward. The thing enters. It fills the room. The light is blinding. The sound is deafening.

You stand up. You do not run. You do not fight. You walk toward it. You walk toward the light.

The old man screams. It is a scream of grief. It is a scream of acceptance.

"Wait!" he calls out. "Remember! Remember the truth!"

You stop. You turn to him. The light is eating you. Your skin is turning to ash. Your eyes are turning to glass.

"What truth?" you ask.

"The truth about justice," he says. "It is not a reward. It is a sacrifice. You are not the hero. You are the cost."

You understand. It hits you like a hammer. It is simple. It is terrible. It is true.

Justice is not something that happens to you. Justice is something you become. You give yourself so that others may live. You give your self so that the world may remain whole.

You look at the old man. You see his face. He is crying. But he is smiling.

"Go," he says. "Save them."

You turn back to the void. You walk into it. You are not afraid. You are calm. You are at peace.

The light takes you. You are gone.

The room is empty. The old man sits on the floor. The dust settles. The silence returns.

He stands up. His legs are stiff. He walks to the door. He looks out.

The forest is quiet. The trees are still black. But there is a change. The air is clearer. The gray sky is lifting. A single ray of sun breaks through the clouds. It touches the moss on the wall. It is warm. It is real.

The thing is gone. The shadow is gone. The scream is gone.

The old man picks up the glass of water. He drinks. The water is cold. It tastes of stone. He spits it out.

He walks out of the structure. He walks into the forest. He does not look back. He knows it is over. He knows he did his part.

He is alone. He is free.

But he is not happy. He is empty. He has lost something. He has lost the fight. He has lost the cause. He has lost the meaning.

He walks on. The sun is higher now. It is bright. It is harsh. It burns his skin. He does not care.

He thinks of you. He thinks of the man who was the threshold. He thinks of the sacrifice. He thinks of the justice that was paid.

It was not fair. It was not right. It was just what had to be done.

He reaches a clearing. There is a road. It is paved with stone. It leads to a town. He can see the smoke from the chimneys. He can hear the sound of birds.

He walks toward the town. He walks toward the people. He walks toward the life that was saved.

He does not know if they will remember. He does not know if they will thank him. He does not know if they will even know that anything happened.

They will wake up. They will go to work. They will eat their bread. They will love their children. They will live.

And that is enough.

The old man enters the town. The streets are busy. People are walking. They are talking. They are laughing. They are alive.

He blends in. He is just another man. He is just another face.

He buys a newspaper. He reads the headlines. They are mundane. They are boring. They are normal.

A cat is found on a roof. A train is late. A painter has died.

There is no mention of the void. There is no mention of the sacrifice. There is no mention of you.

He folds the newspaper. He puts it in his pocket. He walks to a café. He sits down. He orders a coffee.

The coffee is hot. It smells of bean and earth. He drinks it. It is bitter. It is good.

He watches the people. He watches them live. He watches them breathe.

He feels a weight in his chest. It is not pain. It is guilt. It is the guilt of the survivor. It is the guilt of the one who let the other die.

But he knows it was necessary. He knows it was the only way.

He closes his eyes. He remembers the light. He remembers the cold. He remembers the face of the man who was the threshold.

He opens his eyes. He looks at the coffee. The steam rises. It curls into the air. It disappears.

Like you.

Like the truth.

Like the justice that came at a cost too high.

He pays for the coffee. He leaves a tip. He walks out. The sun is setting now. The sky is orange. It is beautiful. It is fleeting.

He walks home. He does not know where home is. He does not have a home. He has only the road. He has only the memory.

He walks into the night. The stars are out. They are bright. They are cold.

He is alive. He is alone. He is free.

And it is not enough.

The story ends. The silence returns. The void is gone. But the hole remains. The hole in the world where you were. The hole in the heart where the truth was.

It will never be filled. It will never be closed.

It is the threshold. It is the door. It is the place where we enter the light.

And we are afraid.

And we are brave.

And we are gone.
