The world was white. Not the white of snow or clouds, but a sterile, aggressive void that existed in every direction. There were no corners in the Sanctuary, only curved walls of matte polymer that seemed to absorb sound and light alike. There was no time, only the Cycle—the rhythmic shift from the 'Waking Light' to the 'Resting Dim.'

And then there was the Noise.

A constant, low-frequency hum that permeated everything. The administrators told us it was the sound of the Earth Engine, the heartbeat of our survival. They said the Noise was a shield, protecting our minds from the madness of the void outside.

I was the lead psychiatrist of the Sanctuary. My job was to treat 'The Silence-Sickness'—a condition where patients began to crave the absence of the Noise.

My latest patient was a man named Julian. He didn't scream, he didn't cry; he just sat in the center of the white room, his eyes wide and fixed on a point that didn't exist.

"I can hear them, Doctor," he whispered, his voice barely audible over the hum.

"Hear who, Julian?" I asked, my voice calm and clinical.

"The ones below. The ones who aren't in the Sanctuary. They're scratching at the floor. They're calling my name."

I sighed and made a note in my tablet: *Patient exhibiting auditory hallucinations. Suggest increasing the Noise amplitude by 10%.*

But that night, as I lay in my own white pod, I felt a sudden, jarring silence. For a fraction of a second, the Noise stopped.

In that gap, I heard it.

A sound that was not a hum, not a vibration, but a voice. A thousand voices, overlapping in a dissonant, guttural choir, screaming from the depths of the planet. They weren't calling for help; they were laughing. It was a sound of ancient, cosmic amusement, as if the very earth we lived in was a joke that had finally reached its punchline.

The Noise returned a second later, washing over me like a warm blanket. I felt a surge of relief, a desperate need for the hum to drown out the memory of that laughter.

The next morning, I visited Julian. He was smiling.

"The Noise is gone, Doctor," he said.

"No, it's right here," I replied, pointing to the speakers in the ceiling.

"Not for me," Julian whispered, leaning in close. "I've learned how to listen to the silence. And the silence says that the white walls are just a shroud. We aren't being saved, Doctor. We're being marinated."

I looked at his eyes and saw a reflection of that same, terrifying laughter. I didn't report him. Instead, I went to the control panel and turned my own Noise up until my ears bled, praying that the hum would never, ever stop.
