Extinction

As predicted by Dr. Sobeck, the Faro Plague overran the planet and obliterated all life, leaving the Earth dead and sterile. The robots consumed all organic matter, exterminating all living organisms, including humans. This happened directly via their consumption of biomatter, and indirectly via consumption of all plant life, which reduced oxygen levels to zero, rendering the atmosphere unbreathable. All land, water, and air became toxic, rendering the Earth unable to support life. With no more biomatter left to consume, the robots, which by then numbered in the millions, went into a state of dormancy, ready to awaken and consume any organic matter should it ever appear.

However, life was not permanently exterminated, as Zero Dawn was successfully completed and implemented before the end. Within 100 years after the extinction of life, GAIA succeeded in brute-forcing the swarm's deactivation codes and transmitted them worldwide, shutting the robots down. Within another 100 years, global flora, some fauna, and finally humans, were restored.

As for the Faro Swarm's robots, they were buried underground in the terraforming process, and with the passage of time, were forgotten by the new humans and their descendants. However, subsequent events led to their rediscovery.
