Jacob (Knight)

Knight Jacob was a Brotherhood of Steel member who helped found Broken Hills alongside Marcus.

Background
The Brotherhood of Steel, at the apex of its power in the 2180s, allowed Brothers to take up oaths to fulfill. Knight Jacob was one of those men and women who swore them, promising to destroy mutants as a sort of latter day knight errant. This put him on a collision course with Marcus, who, following the destruction of Mariposa and the Cathedral, took to the wastes.

Around 2185, he came across Marcus. The two fought intensely for a couple of days, neither of them able to get an advantage over the other, before realizing the futility of the fight. Instead the pair made peace with each other and Jacob abandoned his sworn oath to destroy mutants and joined Marcus in his travels. As they traveled together, discussing Brotherhood doctrine and the Unity (in particular the neurolink between the Master and the Cathedral computers), people gradually started following them. After all, a Brotherhood Paladin and a super mutant veteran? It doesn't get any safer than that. Marcus led the growing group to the site of a pre-War uranium mining town he knew about from old maps.

There, he and Jacob founded the settlement of Broken Hills in fall of 2185. After ensuring that the town survived winter, Jacob said his goodbyes and moved on. Marcus stayed, as mayor and sheriff, though he missed his friend dearly. Particularly the arguments between him and Jacob on dipping and how the latter "would've been a great mutant".

Inhabitants of the settlement would honor his memory by naming their children after him, as is the case with Jacob the Chemist (who isn't as open minded as the original, unfortunately). Marcus would further honor his memory after the fall of Broken Hills, naming a new settlement after him. Jacobstown was established by Marcus as a safe haven for mutants of all kinds and particularly a center of research into a cure for nightkin schizophrenia.

Appearances
Jacob does not appear in any game, however he is mentioned in Fallout 2 and Fallout: New Vegas.
