The Sky Beneath the City

In a sprawling metropolis of glass and steel, a subway worker named Jonah discovered something extraordinary: a tunnel that wasn’t on any blueprint.

Unlike the others, it glowed faintly blue, like moonlight trapped underground. Curious, he followed it, deeper and deeper, until the sound of trains faded and the air grew warm and sweet.

He emerged into an underground world—a vast cavern filled with plants, light, and rivers that shimmered like stars. People were there too, quiet and graceful, living in peace. They called it The Sky Beneath.

Jonah stayed for what felt like a few hours, but when he returned to the surface, twenty years had passed. The city had changed, his home was gone, and no one remembered him.

The climax: Jonah returned to the tunnel, but it was sealed—buried under concrete and silence. Some nights, the maintenance workers say they hear faint humming through the walls, and the scent of flowers that don’t exist above ground.
