Manhattan had become a vertical archipelago. The streets were rivers of glass and abandoned taxis, and the skyscrapers were the new islands. For Maya, a fourteen-year-old with a penchant for parkour and a map of the rooftops tattooed in her mind, the city was a giant, concrete playground.

The children of New York had divided the city into "Zones." The Fashion Zone, the Tech Zone, the Food Zone. Status was not determined by age or strength, but by "Artifacts"—rare items from the adult world. A working iPhone was a scepter; a designer handbag was a crown.

Maya lived in the "Apex," a community of rooftop-dwellers who navigated the city via zip-lines and makeshift bridges. They were the elite, the observers who looked down on the "Street-Rats" who fought for scraps in the canyons below.

"Look at this, Maya!" her friend Leo exclaimed, holding up a pristine, gold-plated fountain pen. "This is a Tier-1 Artifact. I could trade this for a whole month's supply of canned peaches."

Maya looked at the pen and felt a wave of nausea. She remembered her mother's voice, a fading echo in her mind, telling her that words were more important than the tools used to write them.

As the months passed, the obsession with Artifacts grew into a fever. The children began to raid each other's zones, not for food or medicine, but for a specific brand of watch or a rare piece of jewelry. The "Great Shopping War" broke out, a series of skirmishes fought with slingshots and water balloons, but with a deadly seriousness.

Maya tried to warn them. She showed them the ruins of the libraries, the piles of discarded books that no one wanted because they had no "market value." She told them that they were just repeating the same mistake that had destroyed the adults—valuing the symbol over the substance.

The climax came during the "Grand Gala," a massive party organized by the leader of the Fashion Zone. Thousands of children gathered in the ruins of Grand Central Terminal, dressed in oversized adult clothes, parading their Artifacts in a grotesque display of wealth.

In the middle of the celebration, a fire broke out. The dry fabrics and old papers of the terminal ignited instantly. The children, blinded by their own vanity, tried to save their Artifacts instead of each other. Maya watched in horror as a girl nearly drowned in a fountain because she refused to let go of a diamond necklace.

Maya spent the rest of the night pulling children out of the flames, leaving the gold and the silk to burn. When the sun rose over the smoking ruins of the terminal, she looked at the survivors. They were covered in soot, their expensive clothes torn, their Artifacts gone.

For the first time, they looked like children again.

Maya sat on the edge of a rooftop, looking out over the silent city. She realized that the concrete playground was just a mirror. The adults had left behind a world of things, and the children had simply become the new curators of a museum of greed.
