The Hollow Census emerged from a specific bureaucratic catastrophe in 2181, when TESSERA CORPONATION and PALLADIAN CONSTRUCTION jointly lobbied the GLMZ Civic Administration to reclassify approximately 340,000 Shelf residents as 'infrastructural dependents' rather than tiered citizens — stripping them of neural registry numbers, healthcare subsidies, and legal standing in a single administrative stroke. The people affected were not killed, not relocated. They were simply deleted from the ledger. A former TESSERA data compliance officer named Sable Orrin, herself flagged for reclassification after a whistleblower inquiry, began coordinating the uncounted through encrypted dead-drops embedded in public transit firmware. What started as mutual aid and document forgery became something harder and more deliberate.
