Mississippi, 1932. The air was a thick, humid blanket that smelled of river silt and dying magnolias. Silas Thorne lived in the shadow of Blackwood Manor, a crumbling estate that seemed to be sinking into the swamp by sheer force of its own misery. Silas was a man of silence and secrets, a disgraced lawyer who spent his days tending to a garden of poisonous plants and reading books that should have been burned.

Then the Miasma arrived. A pale, greenish fog that rolled in from the bayou, turning the living into "The Echoes"—shambling, mindless versions of themselves, driven by a single, obsessive desire to return to the place they were happiest.

The town of Oakhaven became a nightmare of nostalgia. The Echoes didn't attack with claws; they attacked with memories. They would stand outside your door and whisper the things you most regretted, their voices a discordant choir of the past.

Silas survived because he had no happiness to return to. He had burned every bridge, betrayed every friend, and lived in a state of curated misery. The Miasma found nothing in him to mirror. He was a void, a blank slate in a world of screaming memories.

He turned Blackwood Manor into a fortress of apathy. He didn't fight the Echoes; he ignored them. He spent his time in the library, documenting the collapse of the South, watching as the great plantations were reclaimed by the swamp and the ghosts of slavery and pride merged into a single, suffocating fog.

He took in a few survivors—broken people who, like him, had nothing left to lose. He didn't offer them hope; he offered them the safety of the void. He taught them how to kill their own happiness, how to cultivate a garden of regret so thick that the Miasma couldn't find a way in.

But the Miasma began to evolve. It stopped mirroring the past and started projecting a false future. It created visions of a world where the manor was restored, where the family was whole, where the sins of the fathers were washed away.

Silas's survivors began to succumb. One by one, they walked out into the fog, lured by the promise of a happiness that never existed. Silas watched them go, his face a mask of indifference.

But then, the Miasma found the one thing Silas had tried to bury: the memory of a girl he had loved and betrayed forty years ago.

The fog thickened, taking the shape of a young woman in a white dress, her eyes full of a forgiveness that felt like a knife. She didn't whisper regrets; she whispered a simple, devastating truth: "You didn't survive the Miasma, Silas. You were the Miasma all along."

Silas looked in the mirror and saw not a man, but a pale, greenish fog. He had spent so long cultivating his own void that he had become it. He didn't die; he simply dissolved, becoming another whisper in the humid air of Mississippi, a memory of a man who had forgotten how to be human.
