I

The letter arrived on a night when the Mississippi was thick with fog. I was in the parlour of my family's decaying plantation, surrounded by the smell of damp wood and forgotten things, when the messenger handed it to me without a word. It was wrapped in wax the colour of river mud, and sealed with a symbol I did not recognise—a wheel with no spokes.

My name was written on it in a hand that looked like it had been learned in another century: Elihu Beauregard.

No stamp. No postmark. Just my name and the address of the third pier along the riverbank.

I opened it by the light of a kerosene lamp that hissed and smoked. Inside was a single line of instruction, written in ink the colour of dried blood: You are invited. Come to the third pier along the Mississippi at midnight.

I should have thrown it away. I was a man of twenty-four years, a former officer of the Confederate Army, a man who had returned home to find nothing but ruins and regrets. I had no patience for nonsense. But the wheel on the seal had drawn my eye, and something in me—something I had buried beneath layers of guilt and shame—had stirred.

So I went.

The fog on the Mississippi that night was thick enough to taste. It clung to my coat and filled my mouth with the taste of river mud and decay. The river stretched before me like a black ribbon, and beneath it, in the darkness where the moonlight could not reach, I found the third pier.

And there it was.

The boat was black—not the black of paint, but the black of something that absorbed light rather than reflected it. It had no flag, no name visible on its hull, only two points of white light at the top of its smokestacks, like eyes in the dark. The sound of its steam engine reached me before I could see it clearly—a low, rhythmic chugging that seemed to vibrate in my chest.

A man stood at the foot of the gangplank. He was old, with a grey beard and a face that seemed carved from the same dark wood as the boat. His uniform was immaculate, every button polished, every seam precise.

"Mr. Beauregard," he said. It was not a question.

"Who are you?" I asked.

"The captain," he replied. "And you hold an invitation. May I see it?"

I reached into my pocket and found the letter, though I had left it on my desk. The paper was warm, as though it had been sitting in the sun. I handed it to him anyway.

He examined it for a long moment, then nodded. "You may board."

"Where does this boat go?" I asked.

He looked at me with eyes the colour of the Mississippi at midnight—dark, depthless, impossible to stare into for long. "That depends on what you are looking for."

I should have turned back then. But the invitation had pulled me here, and I was a man who followed invitations. So I stepped onto the gangplank.

The interior of the boat was a single chamber, dominated by a massive steam apparatus at its centre—the captain called it the Wheel of Memory. It was a tangle of pistons and valves and pressure gauges, all humming with a power that made the air taste of coal and river water.

"Step through," the captain said, gesturing to a ring of light at the centre of the apparatus. "And you will arrive at your destination."

"What destination?"

"Your destination, Mr. Beauregard. The South you are meant to visit."

I stepped through the ring.

The sensation was not unlike falling, but without the fear. It was as though my body had been unwound and rewound in the space of a single heartbeat. When I opened my eyes, I was standing on a wooden porch beneath a sky the colour of tarnished brass.

The buildings around me were the South—or a version of the South. The architecture was antebellum, the oak trees draped in Spanish moss, the fields of cotton stretching to the horizon. But something was wrong. The light was different. Heavier. As though the sun itself had been weighed down by centuries of sin.

This was a South where the past had not ended. Where the ghosts had not been laid to rest.

A woman approached me. She wore the dress of a house servant, but her eyes were sharp and assessing.

"You are new," she said. "Which cabin are you in?"

"I—what?"

"Your cabin. It determines what you can see and what you can do here. First cabin, second cabin, or hold."

I looked down at my right wrist. A scar on my wrist had begun to glow—a faint silver light, the kind of light that comes from phosphorus.

"First cabin," I said, though I did not know why I said it.

The woman nodded. "Then you may walk the grounds. Follow the light."

And so my journey began.

II

I returned to my own world after what felt like three years, though the captain told me it had been only three hours. The difference in time between worlds was one of the first things I learned. The Memory does not measure time as we do.

I found myself standing on the third pier along the Mississippi, the fog exactly as I had left it. The boat was gone. But the silver light on my wrist remained, and with it, a memory that felt older than my own life.

The captain invited me back the following week. And the week after that. Each time, I stepped through the Wheel of Memory and arrived in a new South—a slave-holding South where the plantations stretched for miles and the chains never broke, a Reconstruction South where the war had ended but the hatred had not, a Depression South where the dust bowls had turned fertile land to dust and hope to ash.

With each journey, I learned more. The silver light on my wrist pointed me toward certain people in each world—people who held pieces of a puzzle I could not yet see. I was a Beauregard, a man of the South, a man who had spent his life running from his family's history. And these parallel Souths were records of a different kind: living documents of every choice history had not made.

But I began to notice things.

Passengers who did not return.

The captain would announce at the beginning of each voyage: "We sail for a new South tomorrow." And some of the other passengers—there were always others, though I never learned their names—would board with me. But when I returned, they were gone. Not returned to their own world. Gone. Erased.

When I asked the captain about them, he would look at me with those midnight-river eyes and say: "Some passengers find their destination and choose to stay."

But I saw the way his hand trembled when he said it.

III

The discovery happened on my seventh voyage. I had been sent to a civil rights era Birmingham where the streets ran with blood and the churches burned and the dream of equality was still a thousand years away. The silver light on my wrist led me not to the streets, but to the boat itself.

I found a door in the hull that should not have existed. Behind it was a cabin, small and dust-covered, with walls covered in clippings. Hundreds of them, written in different hands, different inks, different decades. Each clipping was followed by a date and a single word: RECORDED.

I ran my finger down the list, and then I stopped.

Elihu Beauregard. Date: 1874. Status: RECORDED.

I was born in 1851.

My hand began to shake. I read the clipping again. And again. And then I looked at the clipping below it.

Elihu Beauregard. Date: 1875. Status: ACTIVE.

There had been another me. A first me. Who had completed his voyage and become a recorder.

I tore the cabin apart. Behind a loose panel, I found a ledger—a record of every passenger who had ever boarded the Memory. A century of names. A century of recorders. The boat was not a vessel of exploration. It was a machine for collecting Southerners, for binding them to the spaces between worlds, where they recorded truths that could never be published.

Every parallel South required a recorder. Every truth required a sacrifice.

I brought the ledger to the captain. He read it silently, his face unreadable.

"How long?" I asked.

"How long has the boat been sailing? One hundred and sixty-seven years. How many recorders has it required? Four hundred and twenty-three."

"Will I become a recorder?"

He was silent for a long time. Then: "You have a choice, Mr. Beauregard. You may destroy the Wheel of Memory. But if you do, every parallel South that depends on the recorders will collapse. The slave-holding Souths you have visited, the Reconstruction Souths, the civil rights era—they will all cease to exist. Hundreds of truths, erased."

"Or?"

"Or you may take the place of the recorder who came before you. You will be bound to the space between worlds. You will watch others travel. You will never leave. But the truths will survive."

I thought of the clippings on the wall. One hundred and sixty-seven years of men and women who had stood where I stood, faced this choice, and chosen to stay.

I thought of the slave-holding South, where the chains had never broken. I thought of the Reconstruction South, where the war had ended but the hatred had not. I thought of all the Souths that existed only because someone had chosen to become a recorder.

"I will stay," I said.

The captain nodded, and for the first time, I saw something in his eyes. Not pity. Not relief. Recognition.

"Welcome aboard, Mr. Beauregard."

IV

I am a recorder now.

The space between worlds is not dark. It is full of light—thousands of parallel Souths, each one a different colour, each one humming with the sound of a million lives. I can see them all, and I can feel the weight of every recorder who came before me.

Sometimes, on foggy nights, I watch the third pier along the Mississippi. I watch for new passengers. I watch for men and women who carry the invitation in their hearts and follow it into the dark.

Last Tuesday, I saw a young man approaching the pier. He carried a letter in his hand, and his eyes were wide with the kind of wonder that only ignorance can produce.

I took a quill from the pocket of my uniform and wrote on the back of his invitation: You are invited.

The Memory is patient. It always has been. And it always will be.
