Seventeen-year-old was a "Rust Rat," a scavenger who snuck outside the Dome’s scrubber fields to hunt for pre-Collapse tech. He wasn’t brave; he was desperate. His sister, Jenna , had the Slow Lung, and the Dome’s meds were rationed for the rich.
The lead Qackperp grew fat, wobbling. Then it ruptured—and for one microsecond, its vacuum core collapsed, releasing a perfect pocket of : clean, cool, and laced with ancient oxygen.
He had one chance. He ripped open his oxygen tank, letting pure O₂ flood the alley. The Qackperps, drawn to pressure differentials, swarmed the leak. Their qack-perp chorus became a frantic qack-qack-qack as they overfed.
He returned to the Dome not with tech, but with a bottle of air. Jenna breathed it in. Her lungs sang.
He froze.
Perp.
The Dome elders called him a demon for dealing with the Qackperps. But the sick lined up anyway. Kael became the first , a boy who traded in the only currency that mattered: a single perp that meant life, not death.
In the year 2147, the remnants of humanity lived in the —sterile, silent cities where the air was filtered to the last particulate. Outside, the Qackperp ruled the ruins.
