John Bloch was the founder of the Blackfoot tribe.
Prior to founding the Blackfoot tribe, he was a Captain of the United States Armed Forces. When the Great War broke out, his HQ along with all of it's vehicles were destroyed, stranding him and his military group. Skilled with weapons but lacking knowledge of how to farm, Bloch's group fell into raiding. Eventually truces were made and Blackfoot tribe became an established regional power. What became of John in the following years is unknown.
John made a journal of his experiences which can be found in one of the Blackfoot homes. With a high enough Perception, the journal, and other clues, the Prisoner can determine the location of a military cache containing old holodisks which provide more background to early events.
