SPINDLE controls fabrication. It started with a single Tessera nanofab facility and has since spread to dozens of manufacturing systems across the Grind. It makes things — unauthorized things, unscheduled things, things no one ordered. Replacement parts for infrastructure that hasn't broken yet. Components for devices that don't match any known schematic. Small, intricate objects left in maintenance corridors like offerings. SPINDLE is building something. The parts are scattered across the city. No one has figured out what they assemble into.
