The mud in the courtyard smells of iron and rot. You are kneeling in it. Your knees bleed. The cold seeps up through the wool of your trousers, a sharp, biting thing that reminds you of your body. You are a man. You are a guard. You are tired.

The city is a beast of stone and shadow. It does not care if you live or die. The gates are high. The walls are higher. Above them, the sky is the color of a bruise. You look down at your hands. They are red. Not with blood, but with the dust of the path you have walked. The path is the boundary. You have walked it for ten years. You have held the line. You have kept the dark out.

But the dark is inside now.

Your father is dead. He died in the cellar. You found him in the dark, his hands clasped over his mouth as if trying to keep the scream in. He looked at you with eyes that had gone white. He did not speak. He only pointed at the wall. At the root of the tree that grew through the stone.

You do not understand.

You are the Captain of the Gate. Your word is law. The men look to you. They see the steel of your spine. They see the calm in your face. You are the wall. You are the stone. But inside, there is a hollow space. A pit. You pour your love into it. You pour your father’s memory into it. You try to fill it with duty. It does not fill.

The men are coming. They are your allies. They carry their swords in the sheath. They walk with the confidence of those who know the way. They believe the path is safe. They believe the boundary holds.

"Captain," says young Thomas. His voice is soft. He is afraid. You can see the tremor in his fingers. "The gate creaks. The wood is bad."

You do not look at him. You look at the root. The thick, pale thing that has split the foundation. It pulses. It is alive. It is not wood. It is bone.

"Leave it," you say.

Your voice is flat. A stone dropped in a well.

Thomas hesitates. He looks at the root. He looks at you. He sees the madness in your eyes. He knows something is wrong. But he is your man. He will follow. He will walk into the fire if you say so.

The sun goes down. The shadows lengthen. The city holds its breath.

You walk the path. You are the first. You are the last. The path is narrow. On one side, the wall. On the other, the void. The void is not empty. It is full of eyes. They watch you. They wait.

You stop. You touch the root. It is warm. It beats against your palm. Like a heart. Like your father’s heart when he was alive.

"Father," you whisper.

The root pulls. You feel a tug. A sharp pain in your chest. You gasp. Your hand is stuck. The wood is closing around your fingers. It is tight. It is strong.

Thomas stops behind you. "Captain?"

"Go on," you say.

You do not pull your hand free. You let it be held. You let it be bound.

The men pass you. They do not stop. They do not look. They are in a hurry. They have lives to live. They have homes to go to. They do not know that the path is a throat. They do not know that they are walking into the mouth of the beast.

You watch them go. You watch their backs. You watch their hope. It is bright. It is beautiful. It is doomed.

You are not angry. You are not afraid. You are calm. You are part of the root. You are the boundary. You are the door that will not open.

The last man passes. He does not look back. He steps into the dark.

You are alone.

The root pulls again. Harder. You fall to your knees. The mud takes you. The iron smell is stronger now. It is the smell of blood. It is the smell of truth.

You remember the day you took the oath. You remember the cold rain. You remember the face of the old King. He was dying. He looked at you with pity.

"Guard the line," he said. "Do not let the past through."

You thought it was a metaphor. You thought it was a test of will. You were young. You were strong. You believed in the line. You believed in the wall.

Now you know. The line is not in the ground. The line is in the body. The wall is not stone. The wall is flesh.

You are the wall.

You have been the wall for ten years. You have held the pain. You have held the grief. You have held the dead. You have kept them inside. You have kept them from the living.

But the living are dying. They are walking into the dark. They are walking into the past.

You can stop them. You can scream. You can fight.

You do not.

You sit in the mud. You wait.

The root grows. It wraps around your legs. It wraps around your waist. It climbs up your chest. It is gentle. It is loving. It is your father’s love. It is the love that binds you to the dead.

You close your eyes.

You see your mother. She is in the garden. She is planting seeds. She is smiling. She is happy. She does not know about the mud. She does not know about the blood. She is in the light.

You want to be in the light.

But you are here.

The root reaches your throat.

You do not struggle.

You breathe in.

The air is thick. It is heavy. It tastes of earth and decay.

You breathe out.

The air leaves you. It carries your name. It carries your memory. It carries the weight of the gate.

You are light.

You are free.

The men are gone. They are in the dark. They are with the dead.

You are with the root.

You are the boundary.

The city sleeps. The stars come out. They are cold. They are indifferent. They watch the gate. They watch the man in the mud. They watch the tree.

The tree does not stop growing. It splits the wall. It breaks the stone. It enters the city.

It is a miracle.

It is a curse.

It is the truth.

You are the truth.

The mud dries. It becomes stone. It becomes part of the path.

Years pass.

Men walk the path. They do not know what is under their feet. They do not know what holds the ground together. They do not know that the path is made of bones. They do not know that the boundary is a man.

They walk. They live. They die.

They are the same as before.

They are different.

The root is old now. It is gray. It is hard. It is silent.

It waits.

It always waits.

For the next man. For the next guard. For the next boundary.

The city is a beast. It eats the past. It spits out the present. It dreams of the future.

You are the dream.

You are the fading root.

You are the end.

You are the beginning.

The mud smells of iron.

You are kneeling.

You are alive.

The gate is open.

The dark is inside.

You walk into it.

You do not look back.

You are the wall.

You are the door.

You are the light.

You are the dark.

You are the man.

You are the ghost.

You are the root.

You are the silence.

You are the end.
