The first sign was the "Flat-Line."

It happened during the First Ascent. We had finally cracked the code of the Fifth Dimension. We didn't just want to see the higher planes; we wanted to inhabit them. We built the Aperture, a ring of superconducting magnets that could fold space like a piece of origami.

I was the lead engineer. I was the one who pushed the lever.

The moment the Aperture opened, we didn't find a paradise of light and geometry. We found a leak.

Something from the Fifth Dimension—not a creature, not a god, but a physical law—began to bleed into our world. It was a "Contamination of Constants." The value of Pi began to fluctuate. The speed of light slowed down in some areas and accelerated in others.

Then, the folding began.

I watched as my laboratory started to overlap with itself. I could see the back of my own head while looking forward. I could hear my voice from ten minutes in the future, screaming in a language I didn't recognize.

"Close it!" my assistant, Marcus, yelled. But as he moved toward the control panel, his body began to flatten. He didn't die; he just became a two-dimensional image, a living photograph pressed against the wall. He was still conscious, his eyes wide with a horror that had no depth.

The contamination spread. The city of New York began to fold like a cardboard box. Skyscrapers bent at impossible angles, intersecting with the subway tunnels. People were fused together—half-man, half-wall, half-ceiling—their screams echoing in a space that no longer had a "direction."

I tried to fight it. I used every scrap of mathematics I knew to stabilize the Aperture. But how do you fight a law of nature? How do you argue with a universe that has decided you are no longer three-dimensional?

I felt the fold reaching for me.

I looked at my hands. They were becoming translucent, then thin, then mere lines of ink on a cosmic page. I felt my consciousness expanding, seeing the world not as a place, but as a series of overlapping sheets. I saw the past, the present, and the future all happening at once, stacked like a deck of cards.

I saw the end.

The leak was not a mistake; it was a correction. Our universe was a bubble, a fragile anomaly in a higher-dimensional sea. The Aperture had simply popped the bubble.

As I felt my last three-dimensional atom collapse into a plane, I had one final thought.

I wondered what it would be like to be the one who opened the door from the other side.

Then, the fold completed. The world became a single, infinite line. And then, the line was erased.
