The fire started in the cellar. I know this because I smelled the sulfur before I saw the smoke. It tasted like old pennies and rotting lilies on my tongue. The air in the throne room was thick, heavy with the scent of ozone and fear. I stood by the window, watching the sky turn the color of a bruise. Below me, the court had descended into chaos. They were screaming for water. They were screaming for mercy. I did not move. I only held the glass. It was a simple object, clear and cold, filled with wine that looked like dark blood. I had held it for three days. I had not drunk a drop. My hand shook, but the glass did not waver.

"Margaret," the King whispered. His voice was thin, stripped of its usual royal weight. He stood behind me, his shadow long and distorted by the flickering light of the dying torches. "What have you done?"

I turned to face him. My face was a mirror. It reflected nothing but the flame outside. I smiled. It was a small, sad thing. A crack in the porcelain.

"I have opened the door, Edward," I said. "You should have kept it shut."

He stepped closer. He wanted to touch me. He always wanted to touch me. His fingers were stained with ink, with power, with the residue of a thousand decisions that had led us here. He reached out, and I let him take my hand. Our fingers intertwined. The warmth of his skin was a shock against the cold of the wine. I felt the pulse in his wrist. It was fast. It was afraid.

"The monks say it is a punishment," he said. His eyes were wide, the whites showing in a ring around the dark. "They say you invited the spirits. They say you are a witch."

"Monks," I laughed. The sound was dry, like leaves skittering on stone. "They know nothing. They only know how to fear what they cannot name. You know the truth. You have always known."

He pulled back. He looked at the window, where the firelight now danced on the stone walls. The heat was rising. I could feel it on my cheeks, a gentle causer that burned.

"I love you," he said. The words were clumsy. They did not fit the shape of the moment. But they were true. That was the tragedy of it. They were true, and they were useless.

"I know," I said. "And I loved you. Before I understood. Before I saw the shape of the loop."

The doors burst open. The King’s guard flooded the room. Their armor clattered, a harsh, metallic sound that cut through the silence. Their faces were pale, their eyes wide with the same terror that had taken hold of the court. They did not draw their swords. They knew they could not stop what was coming. They only watched. They were witnesses. They were part of the machinery.

The High Priest stepped forward. He was an old man, his skin like parchment stretched over bone. He carried a censer, the smoke from it curling into the air like a snake. He stopped before me. He did not look at the King. He looked at the glass in my hand.

"You have failed," the Priest said. His voice was low, a rumble of distant thunder. "The seal is broken. The cycle is complete."

I looked at the glass. The wine inside was swirling, though the air was still. It moved of its own accord, forming shapes, forming faces. I saw my own face in the liquid. Young. Bright. Full of hope. I saw Edward, young and strong, his eyes full of a promise he had never meant to keep. I saw the room, empty and waiting.

"It is not a failure," I said. "It is a return."

The Priest stepped closer. He raised the censer. The smoke thickened, obscuring his face. I could not see his eyes. I could only see the glow of the embers.

"You think you are the first," he said. "You think your love is unique. Your pain is unique. It is not. It is a gear in a machine that has turned for centuries. You are not the master of this house, Margaret. You are its prisoner. And you have just turned the key on yourself."

I felt the truth of it settle in my bones. It was cold. It was heavy. It was the weight of all the women who had stood in this spot, holding this glass, waiting for this fire. I thought of my mother. I thought of her mother. I thought of the hands that had held this glass before mine. They were all there, layered in the smoke, in the wine, in the heat.

"Why?" I asked. My voice was barely a whisper. "Why did you let me?"

The Priest smiled. It was a terrible smile. It was the smile of a man who has seen the end and found it acceptable.

"Because you are the key," he said. "And the lock is your heart. It could only be opened by someone who loved deeply enough to break."

I looked at Edward. He was weeping. Silent tears tracked down his cheeks. He reached for me again, but I stepped back. I could not let him touch me. If I let him touch me, I would remember. I would remember the life we had before the fire. The laughter. The sun on the garden path. The way he had kissed my forehead in the morning. I had to forget. I had to let it go. I had to become the door.

The heat intensified. The stone walls groaned. The torches sputtered and died. The only light now was the fire outside, and the glow of the embers in the censer. The smoke filled the room, thick and suffocating. I could not breathe. But I did not cough. I held my breath. I held the glass.

"Open," I said.

The Priest nodded. He raised the censer higher. The smoke swirled, forming a vortex around me. I felt a pull, a tug in my chest, like a hook in the flesh. It was not pain. It was release. It was the end of the struggle. I had fought so hard against the darkness, against the inevitability of it all. I had tried to conquer it with my will, with my love, with my cleverness. I had thought I could outsmart the cycle. I was a fool. We are all fools, trying to hold back the tide with our bare hands.

The glass shattered.

It was not a loud sound. It was a soft, crystalline sigh. The wine spilled onto the stone floor, spreading out like a dark stain. It did not stain. It sank. It disappeared into the stone, as if the floor was hungry. As if the floor was waiting for it.

I felt the pull again. Stronger now. My feet left the ground. I was floating. I was light. I was nothing. I looked down at my hands. They were translucent. I could see the stone through them. I looked at Edward. He was reaching for me, his mouth open in a silent scream. I wanted to go to him. I wanted to tell him I was sorry. I wanted to tell him that I had tried. I wanted to tell him that I was afraid. But I could not. The words were stuck in my throat. The smoke was filling my lungs.

The fire roared. It poured through the window, a wall of orange and yellow, consuming the darkness. It did not burn me. It embraced me. It was warm. It was welcome. It was the only thing that had ever been real.

I saw the threshold. It was not a door. It was a line. A thin, bright line that stretched across the void. On one side was the life I had known. The pain. The love. The betrayal. On the other side was the silence. The peace. The end.

I looked back at the room one last time. The Priest was gone. The guards were gone. Edward was gone. There was only the fire. And the glass. The shards of the glass were floating in the air, suspended in the smoke. They caught the light. They sparkled. They were beautiful.

I stepped forward.

I crossed the line.

The pain vanished. The fear vanished. The love vanished. All that remained was the echo. A faint, distant hum, like a bell struck in an empty cathedral. It was the sound of the cycle turning. It was the sound of the next one beginning.

I am Margaret. I am the keeper of the threshold. I am the one who waits. I hold the glass. I watch the sky. I wait for the next one to come. I wait for the next one to break. I wait for the next one to love.

The fire is still burning. It has been burning for a long time. It will keep burning. It is the only thing that stays. It is the only thing that remembers.

I pick up the shards of the glass. I put them back in my hand. I wait.

The smoke clears. The room is empty. The stone is cold.

I am alone.

I am ready.

The door opens.
