The fog did not roll in; it descended, a heavy, velvet shroud of charcoal grey that erased the cobblestones of Kensington and swallowed the gaslights one by one. Inside the drawing room of the Sterling estate, the air smelled of old parchment and dying lilies.

Arthur Sterling, once the most celebrated astronomer of the Royal Society, did not look at the telescope. He looked at Clara. She sat by the window, her frame so fragile it seemed a sudden draft might shatter her like fine porcelain. Her breathing was a shallow, rhythmic clicking, a clock winding down.

"Do you see it, Papa?" she whispered.

Arthur looked. Beyond the glass, the fog had begun to pulse. It wasn't weather; it was a presence. A vast, unseen hunger that had drifted across the void to find this specific, lonely island of existence. He knew the mathematics of it—the way the stars had begun to warp, the way the gravity of the house had shifted, making the tea in the cups lean precariously to the east.

"It is merely a passing cloud, my darling," Arthur lied. His voice was a dry rasp.

He remembered the letters from the colonies, the reports of cities in the East simply vanishing into a grey haze, leaving behind nothing but empty clothes and silence. The "Void-Eater," the papers called it in hushed, terrified tones. To the world, it was a cosmic catastrophe. To Arthur, it was the thief coming for the only thing he had left.

Clara leaned her head against the pane. The fog touched the glass. A single, grey tendril curled around the frame, tasting the warmth of the room.

"I feel it," Clara said, a small, sad smile touching her lips. "It feels like a long sleep. Like the snows of the Highlands."

Arthur knelt beside her, clutching her cold hand. He thought of the Great Engine he had tried to build in the cellar, a desperate machine of brass and mercury designed to push the fog back. It had failed, of course. Against a hunger that consumed galaxies, a machine of gears was a child's toy.

The fog breached the window. It didn't break the glass; it simply flowed through the pores of the wood, a silent, suffocating tide. It filled the room, erasing the mahogany desk, the velvet curtains, and the portraits of ancestors who had once believed in the permanence of the British Empire.

"Close your eyes, Clara," Arthur whispered, pulling her into his arms.

As the grey void closed over them, Arthur didn't pray for salvation. He simply held her tighter, ensuring that in the final, frozen second of human history, she would not be alone. The fog claimed them both, and the house on Kensington Road became a ghost of a ghost, a silent requiem in a universe that had forgotten the meaning of light.
