The glass is in your hands. It is a heavy thing, a chalice of twisted emerald, and it is cracked. You know it is cracked because you can see the light fracturing through the fractures, scattering into a hundred jagged diamonds on the stone floor of the cellar. You are a glassmaker. Your hands are scarred with white lines where the heat has taken you, where the fire has eaten the flesh. You have spent forty years in this cellar, beneath the town of Oakhaven, shaping molten sand into vessels for the nobility above. But tonight, you are not making. You are holding. You are holding the only thing that was ever truly yours.

The door above creaks. It is a slow, agonizing sound, the sound of hinges weeping against the dark. You do not look up. You know who is coming. It is Aldous. He is your apprentice, though he has been with you for twenty years, longer than a son should stay a father’s shadow. He is tall, pale, and he moves with the careful precision of a man who knows that a single misstep could shatter the world.

"Master," he says. His voice is thin, stripped of its usual warmth. "They are coming."

You turn the glass in your hands. The crack runs from the lip to the base, a vein of darkness in the green. "Let them come," you say. Your voice is rough, like gravel underfoot. "I am not done."

Aldous steps into the cellar. The air is thick with the smell of sulfur and old wood. He wears the armor of the King’s Guard, but it looks ill-fitting on him, too large, as if he has not eaten enough to fill it. His face is a mask of terror, but it is not for himself. It is for you. It is for the glass.

"The King’s men are at the gate," Aldous says. "They say you have stolen a relic. They say you have bound a spirit to the glass."

"I have bound nothing," you say. "I have only made it. The spirit was already there, in the sand, in the fire. I merely gave it a shape it could hold."

Aldous walks to you. He stops an arm’s length away. He is trembling. "You must give it to them, Thomas. If you do not, they will burn the cellar. They will burn us."

You look at him. You have always loved him, in the way a craftsman loves his finest tool, in the way a father loves a child who will never be free of the workshop. Your devotion to him is a heavy stone in your chest. You have protected him from the heat, from the dust, from the slow blindness that takes the eyes of the glassmakers. You have kept him in the dark so that he could see the light.

"I will not give it to them," you say.

"Thomas, please."

"I will not."

The door above bursts open. Boots on stone. Many boots. The sound is a drumbeat in the dark. Aldous closes his eyes. He is trying to be brave, but he is only a boy in a man’s armor.

"They are here," he whispers.

You lift the glass. The light from the tallow candle catches the fractures. For a moment, the air in the cellar seems to thicken, to shimmer. A low hum begins, a sound that is not quite sound, a vibration in the teeth, in the bones. It is the sound of the sand remembering the sea.

The cellar door is thrown open. Torches flood the space with harsh, orange light. Three men enter. They wear the red coats of the King’s Guard. Their faces are hidden behind iron masks, their eyes narrow slits in the metal. They are tall, imposing, and they smell of iron and sweat.

"Thomas Blackwood," the lead guard says. His voice is distorted by the mask. "You are under arrest for the crime of sorcery."

"I am a glassmaker," you say. "I make things. That is all."

"You have made a thing that kills," the guard says. "The King’s son died in his sleep. The doctor says his heart stopped. We found the glass in his room. We know it was your making."

You look at Aldous. Aldous does not look at you. He looks at the floor. He is accepting this. He has accepted it for years. He has watched you work, watched you pour your soul into the glass, watched you become less than a man and more of the fire. He knows what the glass is. He knows it is not a weapon. It is a mirror. It reflects the soul of the holder. And your soul is broken.

"I did not put it in his room," you say. "I gave it to the Duke. The Duke gave it to the King. The King gave it to his son. I am not responsible for their greed."

"Seize him," the guard commands.

Two of the guards move toward you. They carry clubs of black iron. You do not move. You hold the glass tightly. The crack seems to widen. The hum grows louder. The torches flicker.

"Thomas, let go," Aldous says. He has stepped forward. He is between you and the guards. "If you fight, they will kill you. And they will kill me."

"I am not fighting," you say. "I am waiting."

"Waiting for what?"

"For the end."

The guards raise their clubs. The air is tense, a wire pulled too tight. You feel the heat in your hands. It is not the heat of the furnace. It is the heat of the glass itself. It is alive. It wants to be whole. It wants to be shattered.

One of the guards swings. The club hits your shoulder. You do not feel pain. You feel a dull thud, like a hammer on a bell. You stumble, but you do not fall. You hold the glass up. The light from the fractures explodes. It is not light. It is a wave of force, a ripple in the air. The guards stagger back. Their masks crack. The iron splits.

The lead guard falls to his knees. He is screaming, but there is no sound. The other two are frozen, their eyes wide, their bodies locked in a trance.

Aldous stares at you. His face is a mask of awe and horror. "What is it?" he asks.

"It is me," you say. "It is what I have become."

You look at the glass. The crack is now a chasm. The green glass is swirling, a galaxy of emerald and black. You see your own face in it, but it is older, older than you have ever been. It is the face of the first glassmaker, the one who made the first vessel, the one who knew that to create is to destroy.

You understand now. The King’s son did not die because of the glass. He died because he looked into it. He saw his own greed, his own cruelty, and his heart could not bear the weight of it. The glass does not kill. It reveals. And revelation is a violence.

You have been holding this secret for twenty years. You have been hiding in the cellar, hiding from the world, hiding from the truth. You thought you were protecting Aldous. You thought you were protecting yourself. But you were only protecting the glass. You were feeding it. You were feeding it your fear, your anger, your sorrow. And it has grown strong.

Aldous takes a step back. "Thomas, put it down."

"I cannot," you say. "It is part of me."

"It is killing you."

"Yes."

"Then let it die."

You look at him. He is young. He is clean. He has never been in the fire. He does not know what it is to be consumed. He does not know that to be a craftsman is to offer yourself to the work.

"I cannot let it die," you say. "Because if I let it die, I will die too."

"Then die," Aldous says. "But let me go."

You look at the guards. They are still frozen. The lead guard’s mask is in pieces. His face is a ruin. He is breathing, but he is not alive. He is a vessel, like the glass. He is empty.

You realize what you must do. You have been holding the glass for so long that you have forgotten how to let go. You have forgotten that the glass is not yours. It belongs to the world. It belongs to the fire. It belongs to the dark.

You raise the glass to your lips. The crack is at your mouth. You can feel the cold of the glass against your skin. You can feel the hum in your teeth.

"Thomas, no," Aldous says. He is crying. His tears fall on the stone floor.

You drink.

There is no taste. There is only light. The light explodes from the glass. It fills the cellar. It fills your eyes, your ears, your mind. You see the world as it is. You see the King’s son, dead in his bed. You see the Duke, rotting in his castle. You see Aldous, standing in the dark, weeping for a man he thought he knew.

You see yourself. You see your hands, scarred and white. You see your heart, a lump of cold ash. You see the love you have for Aldous, a love that is a chain. You see the devotion you have for your craft, a devotion that is a prison.

You are not a master. You are a slave. You are a slave to the glass. You are a slave to the fire. You are a slave to the fear of being nothing.

The light is too bright. You cannot see. You can only feel. You feel the glass breaking in your hands. You feel the shards slicing your skin. You feel the blood mixing with the green.

You drop the glass.

It shatters on the floor. A thousand pieces. A thousand mirrors.

The light fades. The hum stops. The cellar is dark again. The torches are out. The guards are on the floor, unconscious, or dead. You do not know. You do not care.

You are on your knees. Your hands are bleeding. The blood is red, bright, and warm. It is the only real thing in the world.

Aldous is beside you. He is holding your hands. He is washing the blood away with his shirt. His hands are steady. He is not afraid.

"Thomas," he says. "You are alive."

"Yes," you say. Your voice is a whisper. "I am alive."

"The glass is gone."

"Yes."

"Are you okay?"

You look at the floor. The shards are scattered. In the darkness, they are invisible. But you know they are there. You know they are waiting.

"I am not okay," you say. "I am empty."

Aldous holds you. He pulls you close. You feel his heartbeat in your chest. It is strong. It is steady. It is the only sound in the world.

"I am here," he says. "I am here."

You close your eyes. You feel the pain in your hands. You feel the cold of the cellar. You feel the weight of your life, the forty years of fire and sand. It is heavy. It is unbearable. But it is yours. It is real.

You are not a master. You are not a slave. You are a man. And you are alone.

But you are not alone.

Aldous is there. And that is enough.
