The rain had been falling on Castle Ashwick for a thousand years. At least, that was how it felt to Sir Aldric.
He stood at the eastern parapet with his hand on the cold stone, watching the same drizzle soak the same fields, the same distant torches flickering in the besiegers' camp. He knew every torch by heart now. There were forty-seven of them, arranged in a crescent that had not moved since the first day of the siege — or rather, since the first day of the siege that Aldric could remember, which was also the only day of the siege he would ever remember, because it was the same day over and over and over.
"I've counted the stones in this wall," he said aloud. No one was there to hear him. "Two thousand, four hundred and twelve. I've counted the crenellations. I've counted the flags in the great hall, the suits of armor, the leaks in the roof above the kitchen. I know that Cook Brenna hides a flask of mead in the third barrel from the left. I know that young Page Tomas will cry when the first arrow lands. I know that the siege tower will reach the west wall at the fourth hour after noon, and that I will kill six men before they push me back, and that I will die at sunset when the third wave breaches the inner gate."
He paused. The rain continued. The torches continued to burn.
"And the next morning, I wake up in my bed, and the rain is falling, and the siege has not begun yet, and I have to do it all over again."
This was the three hundred and twelfth repetition. Aldric had kept count by carving tally marks into the underside of his bed frame, where no one else would see. He had stopped hoping for rescue after the fiftieth repetition. He had stopped wondering what sin he had committed to deserve this after the hundredth. Now he simply endured, the way a stone endures the weather — not because it has strength, but because it has no other choice.
The stranger appeared at noon.
Aldric was in the great hall, eating the same bowl of stew he had eaten three hundred and twelve times, when the air at the center of the room began to shimmer. The knights at the nearby tables did not notice. The servants did not notice. But Aldric had been paying attention to the wrong things for so long that he had trained himself to see the cracks in the world — the places where the repeated day rubbed thin against itself, where the edges of reality frayed like old rope.
The shimmer became a tear. The tear became a door. And through the door stepped a woman in clothes that hurt to look at — fabric that seemed to be made of light and silence and the kind of blue that only exists in deep water.
"Sir Aldric," she said. Her voice was tired. Her face was young, but something old lived behind her eyes. "My name is Doctor Hana Saito. I built the machine that broke you. I have come to apologize."
The hall froze. Not the people — Aldric was used to them ignoring anything strange, because the day did not permit deviation. But the colors of the hall seemed to mute, the sounds of the fire and the chatter to recede, as though Hana Saito carried a pocket of quiet wherever she walked.
"You built this?" Aldric asked. He was not angry. He had exhausted anger somewhere around the hundred-and-seventieth loop, when he had tried to change the siege by poisoning the well in advance and found the well clean and full the next morning regardless.
"Yes." She sat down across from him. The bench did not creak. Nothing in her presence made any sound at all. "I was twenty-four years old, working on temporal resonance theory. I thought I was unlocking the secrets of the universe. I did not realize I was creating a... a splinter. A place in time where the thread of causality had looped back on itself and knotted."
She gestured vaguely, as though encompassing the castle, the siege, the rain, the entire world. "This is that knot. You are caught at its center."
"Can you undo it?"
Hana Saito looked at him. It was a long look, the kind that carries more weight than words. And in that look, Aldric understood something he had not allowed himself to fully accept in all three hundred and twelve repetitions.
"No," she said. "I cannot. The loop is stable. It will not degrade. It will not break. It will simply continue, as it has always continued, as it always will."
Aldric had expected this answer. He had hoped for a different one, but he had expected this.
"Why are you here, then?"
"Because I wanted you to know." Her voice cracked, just slightly. "I wanted you to know that you are not being punished. You are not being tested. You are not a lesson or a warning or a judgment. You are a mistake. A beautiful, terrible mistake that I made because I was young and brilliant and foolish, and I have spent the rest of my life — the real life, the one outside this loop — trying to find a way to tell you that I am sorry."
Aldric stared at his stew. It was cold now, the fat congealing on the surface. He had eaten it cold before. He would eat it cold again.
"In the world outside," he said slowly, "how long has it been since you made this mistake?"
Hana Saito closed her eyes. "Seventy-three years."
"Seventy-three years." He almost laughed. "And you have spent them looking for a way to apologize."
"There is more." She reached into the folds of her impossible garment and produced a small object — a stone, smooth and gray, warm to the touch. "The loop contains all of Castle Ashwick, but it also contains a small amount of... let us call it surplus. Extra time. Unallocated moments that accumulate at the edges of the loop like foam on a riverbank."
She placed the stone on the table between them.
"I have been threading these extra moments into a single container for forty years. This stone holds approximately three hours of real, un-looped time — time that exists outside the cycle, time that you can use however you wish. It is not freedom. It is not escape. But it is a gift, from one prisoner of time to another."
Aldric picked up the stone. It was warm. It hummed faintly against his palm. He had not felt anything new in three hundred and twelve days. This was new. This was real.
"What happens when I use it?"
"You will experience three hours that no one else will remember. You can walk beyond the siege lines. You can see the river, the forest, the sky. You can feel the sun on your face without knowing it will be erased. And when the three hours end, you will return to the loop, and the loop will continue as before."
Aldric turned the stone over in his hands. It was small. It was finite. It was the most precious thing he had ever held.
"Three hours," he said.
"Yes."
"Out of an eternity."
"Yes."
He looked at Hana Saito. She was crying, silently, her face composed but her eyes betraying seventy-three years of guilt.
"Thank you," he said.
She nodded. The air began to shimmer again, the tear opening behind her, the fabric of reality parting to let her leave. She stood and walked toward it, pausing at the threshold.
"Sir Aldric," she said without turning around. "There is something else I want you to know. In the real world, you died in the siege. The siege ended. The castle fell. You were a footnote in a history that no one reads anymore. But here, in this loop, you have lived three hundred and twelve days. You have defended this castle three hundred and twelve times. You have fought, and you have endured, and you have never stopped trying. That may not matter to the universe. But it matters to me."
She stepped through the tear. The door closed. The colors returned. The sounds of the hall flooded back, the fire crackling, the knights talking, Cook Brenna shouting at a scullion.
Aldric sat alone at the table with a small gray stone in his hand.
He did not use it that day. He went to the wall, fought the siege, killed six men, and died at sunset. And the next morning, he woke in his bed with the rain falling and the stone still warm on his chest.
For the first time in three hundred and thirteen repetitions, Aldric did not carve a tally mark. Instead, he walked to the eastern parapet and looked at the sky, and he thought about three hours.
He thought about the river he had never seen, the forest he had never touched, the sun that would rise whether he was there to witness it or not. He thought about the woman who had spent seventy-three years trying to apologize to a dead man in a broken moment. He thought about the strangeness of being seen — truly seen — by someone who understood what it meant to be caught in something larger than yourself.
He held the stone. It was warm.
He did not use it yet.
But he knew, with a certainty that had nothing to do with hope and everything to do with grace, that when he finally did, he would not spend the three hours running or fighting or searching for an escape that did not exist.
He would simply walk into the forest, sit beneath a tree, and let the sun touch his face. And for three hours, he would stop being a knight in a repeating siege. He would simply be a man, existing in a moment that mattered because he chose to experience it.
That, he decided, was not despair. That was something else entirely. Something he had not felt in three hundred and twelve days.
He did not have a word for it yet. But he thought he might learn, in the time he had left, whatever that time was — whether three hours or three hundred years — and that the learning would be enough.
