The Silo

Lore & Background

History within the Silo is fragmented and controlled. Official records state that the surface was poisoned by industrial pollution or war, necessitating the construction of the bunker before the collapse became total. However, rumors persist among the workers that the outside world might be recoverable, or that the Silo itself is a test rather than a salvation. The society functions on a rigid caste system based on job assignments: Mechanics maintain life support, Farmers grow food in artificial light, and Administrators enforce laws.

The most feared role belongs to those sent out to clean the air filters at the surface; they rarely return alive, as they are sent out to die from exposure, not subjected to memory alteration. Deep lore suggests that previous Silos were destroyed or abandoned, but this is not established in widely-known canon. The current structure is a relic of a lost age, built with technology and resources that no longer exist within its walls. Multiple Silos exist—50 in the books, 10 in the TV series—forming a network of isolated bunkers.
