The Railroad agent code-named "Blackbird" was stationed at Augusta safehouse. He had managed to survive an invasion of the compound by a synth raiding party sent to destroy the safehouse and exterminate all of its inhabitants. They had wiped out the entire facility, slaughtering the entirety of the agents stationed there in the process. The attack left Blackbird as the only confirmed survivor, yet there was a synth residing at the safehouse who may have survived.
↑ 1.01.1Note from Blackbird: "Augusta overrun. Two coursers, unknown number of old-models. I'm the only survivor. They came straight at us, knew our location. Package's fate is unknown. If I don't make it out, make them pay."
