Foster was a member of the Army. He was host to two separate Travelers: an unnamed Traveler who was a Faction loyalist; and Traveler 0017, a programmer.
History[]
0017 Future History[]
Traveler 0017 was a programmer responsible for maintaining the Director. He was one of four candidates the Director suspected of being loyal to the Faction, which proved untrue in his case.
Host[]
Little is known about Foster's life prior to being overwritten. He was a member of the United States Armed Forces, which likely lead to his selection as a host.
Unnamed Traveler[]
Foster was overwritten at some point by a Faction Traveler whose consciousness had been stored in the quantum frame. Along with Jones and Pike, he was captured by the core team and taken to a church, where the trio were overwritten once more.
Traveler 0017[]
Pike introduced the three newly arrived Travelers as judges of a tribunal to prosecute Grace Day. Foster questioned the first witness, Grant MacLaren, and interjected a few times during further testimony. He was present when the real traitor, Jones, was apprehended.
