In a future where humanity is confined to the Isola, a towering city of crystalline spires and rigid social strata, Silas is a weary "Clarity Technician." His life is defined by a single task: hanging from the sides of skyscrapers to scrub the glass clean so the wealthy can enjoy an unobstructed view of the horizon. In a world where air is a commodity and transparency is a tool of state control, Silas lives as an invisible ghost in the machine, maintaining a perfection he cannot share.
