The letter begins with a tremor in the ink.

You are here. Not in the body you left in the snow, but in the chair by the cold hearth. The year is unknown. The walls are stone, thick as the skin of an old man. You wear a tunic of rough wool. It smells of woodsmoke and dried herbs. This is not a dream. It is the record of a shift in the substrate. You are Elias. You are no longer the engineer who calibrated the atmospheric scrubbers. You are the son of the lord of the manor. You are old.

Your hands are mapped with veins like rivers on a map. The skin is paper-thin. You look at them and see the ghost of your former self. The fingers that once typed code now shake when they hold the cup. The cup is clay. Chipped. The liquid inside is black. It is not tea. It is a tincture. The healer, a woman named Mara with eyes like flint, poured it this morning.

Take it, she said. It will hold the fever back.

You drank. The taste was bitter. It coated your tongue in a film of ash. The fever came and went like a tide. But it is always coming back. The system is failing. The body is a machine, you think, but the machine is rusting from the inside. You do not fight it. You have no energy to fight. You only observe.

Your brother, Thomas, is in the yard. He is chopping wood. The axe bites into the oak. Thud. Thud. The sound is rhythmic. It is the heartbeat of the house. Thomas is strong. His shoulders are broad. He is thirty. He is you, before the rot set in. He is the variable you cannot control. He is the future.

You watch him through the window. The glass is warped. It distorts his shape. He looks like a monster for a second. Then the light shifts, and he is just a man.

Mara enters the room. She carries a bowl of broth. The steam rises in a curl. It looks like smoke. It looks like a signal.

Your pulse is fast, she says.

It is always fast, you say. Your voice is a rasp. A dry leaf scraping over stone.

We must adjust the dosage.

There is no dosage. There is only time.

She frowns. She does not understand. She is a product of this world. She believes in humors. In balance. You believe in entropy. In decay. You have carried this knowledge across the gap. You are an exile from a future that never was. Or perhaps you are from a past that never ended. The distinction is academic.

The broth is cold. You do not drink it. You push the bowl away. The clay clinks against the wood of the table.

Mara leaves. The door creaks. The sound is a sigh.

You look at your hands again. The tremor is worse today. You try to write. The quill slips in your fingers. The ink spills. It spreads across the parchment like a bruise. Black. Dark. It forms a shape. A gear. A wheel.

You are losing the ability to hold the tools. This is the sacrifice. Not of life. But of agency. The body is taking its own. You are being overwritten.

Thomas enters. He does not knock. He is young. He has forgotten the etiquette of age. He drops the axe on the floor. The wood shudders.

Brother, he says.

You do not look up. You watch the ink dry. It becomes a permanent stain.

You are burning up, Thomas says.

It is only the sun.

It is November.

You finally look at him. His face is wet. Sweat. Or tears. In this light, it is hard to tell.

I am not dying, you say.

You are, Thomas says. His voice is hard. Like the wood.

The room is cold. The fire has died to embers. They glow red. Like eyes.

You stand. It takes effort. Your knees buckle. Thomas catches you. His arms are around your chest. He is solid. He is warm. You smell his sweat. It smells of labor. Of life.

Let go, you say.

No.

Let go.

He does not. He holds you tighter. He is trying to save you. He thinks he can. He thinks if he holds you, you will not fall. He is a good brother. He is a good man. He is wrong.

You push him away. Gently. But firmly.

I am going to the cellar, you say.

The cellar?

There is something there.

What?

You do not answer.

He follows you. You walk down the stairs. The stones are wet. Your feet slip. Thomas takes your arm. He guides you.

The cellar is dark. You light a candle. The flame is small. It flickers. The air is thick. It smells of damp earth and old grain.

There is a barrel in the corner. It is oak. Banded with iron. The iron is green with rust.

You open the lid.

Inside are bottles. Glass. Stoppered with wax.

Thomas looks at you.

What is this?

Wine, you say.

Old wine, Thomas says.

It is not wine.

It is an extract. Distilled. Concentrated. It is the last of the tinctures. The ones that stopped working. The ones that only delayed the inevitable.

You pick up a bottle. The glass is warm. It hums in your hand.

You drink.

The taste is electric. It is sweet and sharp. It burns down your throat. Your heart races. The tremor in your hands stops.

Thomas watches you. His eyes are wide.

What did you do? he asks.

I chose, you say.

Chose what?

To end it.

He grabs your arm.

No.

You look at him. You see your own face in his. You see the fear. You see the love. It is instinctual. It is primal. It is the bond that holds the tribe together.

You see the shadow. You see the man who will grow old. The man who will break. The man who will need to be held.

You take the bottle from your hand. You place it on the table.

I cannot do this, you say.

Thomas holds your hand. He squeezes.

Come back, he says.

You go back up the stairs. The light is grey. The sun is setting.

Mara is waiting. She looks at the bottle in your hand. Her face is blank.

You did not drink it, she says.

No, you say.

Good, she says.

She takes the bottle. She pours it into a bowl. She mixes it with water.

Drink, she says.

You drink. The water is bland. It tastes like nothing.

Thomas is in the yard. He is chopping wood. Thud. Thud.

You go to the window. You watch him. The light is fading. The shadows are long.

You are not the engineer. You are not the exile. You are Elias. You are the brother. You are the old man.

The body is a machine. But the machine is not the purpose. The machine is the vessel. The vessel is breaking.

You accept it.

The fever returns. You feel it in your bones. A heat. A fire.

You do not fight it.

You close your eyes.

The letter ends.

The ink is dry.

The page is blank.

You are here.

The chair is cold.

The fire is out.

Thomas is in the yard.

The axe falls.

Thud.

Thud.

The sound is the heartbeat.

The sound is the end.

You breathe in.

You breathe out.

The air is cold.

The air is clean.

You are alive.

You are here.

The year is unknown.

The walls are stone.

You are old.

You are Elias.

You are home.

The tremor is gone.

The hands are still.

The cup is empty.

The room is quiet.

The light is gone.

The dark is full.

You are here.

You are here.

You are here.

The letter is sealed.

The wax is red.

The name is written.

Elias.

The door opens.

Thomas enters.

He holds a lantern.

The light is yellow.

It falls on your face.

He sees you.

He smiles.

It is small.

It is sad.

It is real.

He sits beside you.

He takes your hand.

His hand is warm.

His hand is strong.

You hold it.

You do not let go.

You do not let go.

You do not let go.

The fire starts.

The smoke rises.

The candle burns.

The night is long.

The night is yours.

You are here.

The story is over.

The story is beginning.

The ink dries.

The page turns.

The silence holds.

The truth is visible.

The truth is simple.

You chose to stay.

You chose to be.

You chose to love.

You chose to live.

The machine stops.

The man remains.

The letter is closed.

The seal is broken.

The end.
