You walk. The mud sucks at your boots. It is heavy. Wet. Cold. You do not stop. You cannot stop. The path is narrow. It cuts through the heath. The wind screams. It sounds like a warning. Or a promise. You do not know which.

Your hand rests on the hilt of your sword. The leather is worn smooth. Thin. Almost translucent. You have held this grip for years. Decades. The metal is cold against your palm. It knows your sweat. It knows your blood. It is an old friend. A bad one.

Who are you? You do not remember your name. Only the duty. Only the weight. You are a knight. Or what is left of one. Your armor is dented. Scratched. The silver is black with age. It fits you poorly now. Your shoulders have shrunk. Your back has curved. You are small. You are tired.

You walk toward the castle. It sits on the hill. Black stone. Tall. Silent. It looks like a skull. You know it. You have seen it in dreams. For a hundred years, you have seen it.

You reach the gate. The wood is iron-banded. Rusted. You knock. No one answers. The silence is thick. It presses against your eardrums. You knock again. Harder. The sound is dull. Dead.

A door opens. Small. Slit-like. A face appears. Pale. Thin. Eyes like chips of glass.

"Who goes?"

The voice is high. Sharp. Young.

"I go to the Lord," you say. Your voice is rough. Like gravel. You clear your throat. You try again. "I go to the Lord."

"Who are you?"

"I am... a servant."

The eyes narrow. "You are not a servant. You are a man. Armed. A man does not come here uninvited."

"I have a message."

"From whom?"

"From the past."

The face vanishes. The door slams shut. You wait. The wind howls. Leaves skitter across the stone. They look like dead flies.

Time passes. An hour. A day. You do not eat. You do not drink. You stand. Your legs shake. Your knees crack. You do not move.

The door opens again. The same face. But now there is anger.

"Leave," the boy says. "Or I call the guards."

"I cannot leave," you say.

"Why?"

"Because I am bound."

"Bound by what? Chains? Vows?"

"By debt."

The boy laughs. It is a cruel sound. "Everyone owes. That is the law. But you? You owe the Lord. He does not forgive. He collects."

"I know."

"Then know this. He is not here. He is dead."

The words hit you. A blow to the chest. You stagger. You catch your balance.

"Dead?" you whisper.

"Three days ago. The plague. Or the fever. They say it was the fever. It took him in his sleep. No pain. They say."

"Who is there?"

"The heir. A child. A boy. He rules now. He is afraid. He is angry. He will not see you."

"He must see me."

"He will not. Go. Leave. Or I will call the dogs."

The dogs. You remember the dogs. They are fast. They are vicious. They smell fear. You do not smell fear. You smell dust. And rot.

"Let me in," you say.

"No."

The door slams.

You turn. You look at the wall. The stone is cold. You press your forehead against it. It is hard. Unyielding. Like your own skull.

You must get in. You cannot stay outside. The cold will kill you. The wind will strip the flesh from your bones. You will become part of the heath. Another ghost. Another whisper.

You look for a way. The wall is high. The gate is barred. You see a window. High up. Broken. A jagged hole in the glass.

You climb.

Your arms ache. The armor drags you down. It is a cage. You climb with one hand. The other holds your sword. The metal bites into the stone. Sparks fly. You ignore the pain. You pull yourself up. Your fingers slip. You catch a ledge. You hang there. The wind tries to push you off. You dig your fingers in. Blood runs. Red drops fall into the darkness below.

You pull yourself over the sill. You drop. You land hard. Your knees buckle. You gasp. The air is stale. Smells of wax. And meat. Old meat.

You are in a hallway. Dark. Shadows dance in the corners. You hear a sound. Footsteps. Fast. Light.

You hide behind a pillar. You hold your breath. Your heart hammers. It is loud. Too loud.

A figure passes. The boy. The heir. He walks fast. He looks over his shoulder. He is wearing a crown. It is too big for his head. It sits crooked.

He enters a room. The door closes.

You wait. You listen. You hear a voice. Low. Murmuring.

"I don't want him."

"Who?"

"Nobody. I just... I feel it."

"Feel what?"

"The weight. It is here. In the walls. It breathes."

You step out from the pillar. You walk toward the room. Your boots make no sound. You are a ghost. You are a shadow.

You reach the door. You push it open.

The room is large. A fire burns in the hearth. It crackles. Spits. The boy sits on a chair. He is shaking. His hands are clenched.

He looks up. He sees you.

"You," he says.

"I am here," you say.

"Get out."

"I cannot."

"Why are you here?"

"To pay the debt."

"What debt?"

"Mine."

The boy stands. He picks up a sword. It is small. A dagger. He holds it out. His hand trembles.

"You are a monster," he says. "They say so. In the village. They say you are a thing of the dark. A demon."

"I am a man."

"No. You are the sin. You are the stain."

You look at him. You see fear. But also something else. Curiosity.

"Who am I?" you ask.

"You are the one who killed him."

The room tilts. The fire flares. Bright. Blinding.

"Killed the Lord?"

"Yes. Three days ago. You came. You wore this armor. You struck him down. In his bed. With this sword."

You look at your sword. The leather grip. The worn metal.

"No," you say. "I did not."

"Everyone saw. The servants. The guards. They saw you."

"You are mistaken."

"I am not."

The boy steps closer. "Look at your hands."

You look. Your hands are dirty. Stained with mud. And blood. Old blood. Dark. Dried.

"It is old," you say.

"It is fresh. It is today's blood."

You look at the boy. His eyes are wide. Terrified. But firm. He believes it. He must believe it. He is the heir. He is the law.

"Who told you this?" you ask.

"The old woman. The maid. She saw you."

"You have never seen me before."

"No. But I have seen your face. In the mirror. In the dark. You are me. You are what I will be."

The words hang in the air. Heavy. Thick.

"You are me?"

"Yes. We are the same. We carry the same weight. The same debt."

You look at the door. The way you came in. The window. The wall.

You could run. You could jump. You could escape.

But you do not.

You lower your sword. You let it fall to the floor. The clang is sharp. Final.

"I do not want to fight," you say.

"Then you die," the boy says. "The debt must be paid. Someone must take the blame. Someone must be the monster. It is you. It has always been you."

You nod. You understand.

The cycle. The loop. The wheel turning.

You are not a knight. You are a sacrifice. You are the shadow that the castle casts. You are the stain that cannot be washed away.

You step forward. You extend your neck.

"Do it," you say.

The boy hesitates. His hand shakes. The dagger points at your throat.

"Why?" he asks. "Why do you accept it?"

"Because it is true," you say. "Not in fact. In spirit. We are bound. By history. By blood. By choice. I am the past. You are the future. The past must die so the future can live."

The boy’s eyes fill with tears. "I don't want to kill you."

"You must. To save yourself."

"If I kill you, I become you."

"Yes."

The boy’s hand drops. The dagger falls. He falls to his knees. He sobs.

"I cannot."

You kneel beside him. You place a hand on his shoulder. It is a gesture of comfort. Of kinship.

"Then we stay," you say. "We stay here. In the dark. In the silence. We wait for the next one. The next heir. The next debt."

The boy looks up. His face is wet. "Is that possible?"

"Yes. We are the keepers. We are the guardians. We do not rule. We endure."

The fire pops. A spark flies. It lands on your sleeve. It burns. You do not move. You let it burn. You let it scar.

The boy stands. He walks to the window. He looks out. The moon is full. Bright. Cold.

"Will you leave?" he asks.

"No. I am part of the wall. Part of the stone. I cannot leave."

"Then I am part of you."

"Yes."

The boy turns. He looks at you. There is no fear in his eyes now. Only sadness. Only acceptance.

"Stay," he says.

You stay.

The door closes. The room is dark. The fire dies. The cold returns.

You sit. The boy sits.

You are two shadows. Merged. One shape.

You wait.

For what?

For the end.

For the beginning.

For the truth.

The truth is simple. It is heavy. It is yours.

You are the threshold.

You are the gate.

You are the door that never opens.

You are the debt that is never paid.

And you are free.

Because you have stopped running.

Because you have stopped fighting.

Because you have become the silence.

The wind howls outside. It sounds like a song. An old song. A lullaby.

You close your eyes.

You breathe.

You are here.

You are gone.

You are everything.

The story ends.

But the debt remains.
