The dream is always the same. You are standing in the courtyard of the Citadel, the stone warm beneath your bare feet, the air thick with the scent of wet mortar and old blood. The walls are high, grey, and endless. They have been here since before you were born, and they will be here after you are dust. You climb them. You have climbed them so many times that the muscles in your legs ache with the memory of the ascent. At the top, the wind is fierce. You look down into the city below, a sprawl of timber and thatch, alive with the hum of ten thousand lives. You are the Warden. You are the shield. And you are afraid.

You wake with the taste of iron in your mouth. The room is dark, the only light coming from the window where the moon hangs like a pale coin. You are in your cell, a small box of stone in the undercroft of the Citadel. The bars are cold against your chest. You press your forehead against them. The metal bites into your skin. This is not a dream. This is the present. And the present is a trap.

"Get up," a voice says from the shadows.

You do not move. You know the voice. It is smooth, polished, devoid of the rough edges that mark the men of the outer guard. It is the voice of Silas, the Quartermaster. He stands at the foot of your bed, holding a lantern. The light flickers, casting long, dancing shadows that seem to stretch across the floor like grasping hands.

"You have slept long enough," Silas says. His face is half-hidden in the gloom, but his eyes are bright, feverish. "The Lord Commander has issued the order. The gate must open. The refugees are at the wall."

You sit up slowly. Your body feels heavy, as if filled with lead. "The gate is sealed," you say. Your voice is rough, unused. "By decree. The city is in quarantine. The plague is within the walls."

Silas steps closer. The lantern sways slightly. "The decree is old. The plague has passed. It is a lie they tell to keep us safe, but it is a lie that kills us. Look out the window, Warden. Look at them."

You go to the window. You push aside the heavy curtain. Below, in the moat, there is a crowd. They are huddled together, shivering, their faces turned upward toward the high walls of the Citadel. They are not dead. They are not rotting. They are simply cold. They are waiting for you to let them in.

"Open the gate," Silas whispers. He places a hand on your shoulder. The touch is light, but it feels like a brand. "You can do it. You are the only one who can. The keys are in your belt."

You look at the key ring. The iron is cold. You have carried it for ten years. You have kept the peace. You have kept the order. But the order is a cage.

"I cannot," you say. "If I open the gate, I am no longer the Warden. I am a traitor."

"Better a traitor who feeds the hungry than a guardian who starves the living," Silas says. He steps back into the shadows. "You have until dawn. The Commander will come for the keys. If you do not open the gate, you will hang with them."

He leaves. The door slams shut. The sound echoes in the undercroft, a sharp crack that splits the silence. You are alone again. You sit on the edge of the bed. The key ring hangs from your belt, swaying gently. You pick it up. It is heavy. It is solid. It is the weight of your duty.

You walk to the window again. The crowd below has not moved. They are still there, waiting. You see a woman holding a child. The child is crying. The woman’s face is hollowed by grief. You recognize her. It is Martha. She lives in the lower district. Her husband was executed last year for stealing bread. You were the one who ordered the execution. You had no choice. The law was the law. But now, looking at her, you see only a mother. And you see yourself in her eyes. You see the fear. You see the hope.

You turn away from the window. You look at the key ring. You think of the Citadel. The stone is warm. The walls are high. They are eternal. They are your mirror. They reflect your strength, your discipline, your loyalty. But they also reflect your isolation. You are a part of the building. You are the stone. And the stone does not feel.

But you do feel. You feel the cold in the bones. You feel the hunger in the belly. You feel the guilt in the heart.

You take the keys. You walk to the door. You lock the cell from the inside. It is a foolish thing to do, but you need to be alone. You need to think. You sit on the floor. The stone is cold against your back. You close your eyes.

You dream again. You are in the courtyard. The stone is warm. You climb the walls. But this time, you do not stop at the top. You climb higher. You climb until the sky is above you. You are no longer in the Citadel. You are in the air. You are free. But the freedom is terrifying. You fall. You fall slowly, your hands reaching for the stone, but the stone is gone. You fall into the dark.

You wake with a gasp. The lantern is still burning. The night is half over. Dawn is coming. You stand up. Your legs are shaking. You walk to the door. You unlock it. The corridor is empty. The silence is heavy. You walk toward the stairs that lead up to the gatehouse.

The steps are steep. Your breath is short. You are tired. You are so tired. You reach the top of the stairs. The gatehouse is before you. The great iron door is closed. Beyond it, you can hear the sounds of the city. The wind. The rain. The cries of the people.

You walk to the lock. You insert the key. It turns with a sharp click. You pull the lever. The gate groans. The iron hinges scream against the stone. The gate opens.

The cold air rushes in. It is biting. It cuts through your clothes. You look out. The crowd is right there. They have not moved. They are waiting for you. You step out onto the threshold. The stone is cold under your feet. It is no longer warm. It is hard. It is unyielding.

Martha is at the front. She looks up at you. Her eyes are wide. She does not smile. She does not thank you. She simply looks at you. And in her eyes, you see the truth. You have not saved them. You have only opened the door. The rest is up to them. And up to the city. And up to the law.

Behind you, you hear the sound of boots on the stone. The Commander is coming. He is fast. He is angry. You turn around. He is standing at the top of the stairs. His face is pale. His hand is on his sword.

"You have betrayed us," he says. His voice is cold. "You have opened the gate to the plague."

"I have opened the gate to the people," you say.

"It is the same thing," the Commander says. "The city is safe when the gate is closed. The city is dead when the gate is open."

He draws his sword. The steel sings in the air. You do not move. You do not raise your hands. You do not run. You stand there, in the wind, in the rain. You look at him. You look at the people behind you. You look at the stone wall.

The wall is eternal. It will outlast you. It will outlast the Commander. It will outlast the plague. It will stand here, grey and silent, long after the last of us has turned to dust.

The Commander raises his sword. The blade glints in the moonlight. You close your eyes. You do not pray. You do not beg. You simply breathe. You feel the cold. You feel the wind. You feel the weight of the keys in your hand.

The blade falls.

You do not feel pain. You only feel a sudden lightness. It is as if the stone has been lifted from your shoulders. You fall to your knees. The blood is warm. It spreads on the cold stone. It mixes with the rain.

You look up. The sky is dark. The stars are out. They are distant. They are cold. They are indifferent. But they are beautiful.

Martha steps forward. She looks at you. She reaches out her hand. She touches your face. Her fingers are warm. Her touch is gentle. It is the only warmth left in the world.

"It is okay," she whispers.

You nod. You cannot speak. Your voice is gone. But you understand. You have let go. You have let go of the stone. You have let go of the duty. You have let go of the fear.

You are no longer the Warden. You are no longer the stone. You are only a man. And the man is gone.

The rain falls. The gate stands open. The people begin to cross. They walk over the stone. They walk over the blood. They walk into the city. They do not look back.

The wall remains. It stands tall. It stands firm. It is eternal. And it is alone.
