Z-15T

The Commonwealth
Z-15T was, like all synths, built inside the Institute. It was a Generation 2 synth, built in 2221 and put to work as a Courser for the Institute. It did his work in the Commonwealth for many years until in 2229 the Broken Mask Incident occurred, creating new problems for the Institute. They were forced to abandon many of the synths who were unable to be communicated with, and one such synth was Z-15T.

Without orders, Z-15T wandered aimlessly, its body deteriorating and its AI realizing that it had free will. It slowly learned to hide from the world as it was continuously fired upon by the people of the Commonwealth, forgetting about its goal of reaching the Institute. Soon enough, it was able to blend into the crowd, wearing concealing clothing and blending in as much as it could. It hid from synths that had been appearing even more over time, learning to fear the Institute as much as it did the Commonwealth.

It was only in 2265 that Z-15T gained real purpose. It located a synth who it had been following for a while, curious as to the synth's fast pace through the streets of Boston. Ambushing the other synth, Z-15T found a record of an order given to the synth by the Institute: to find and locate the Enclave on the East Coast and recover new technologies. The Enclave had apparently been contacted previously by the Institute, and so the synth that had been ambushed and killed by Z-15T was sent to retrieve the order. Recognizing it as a task, Z-15T quickly slipped into a sense of purpose, activating the task that had been put onto the other synth and taking it upon himself to complete it. With a new vigor, Z-15T followed the tracker, going all the way from the Commonwealth to the Virginia Wasteland.
