Hell, yes, I would've. What a great mutant he would’ve been.Marcus commenting on how he would've gladly dipped Jacob if they had crossed paths when he was part of Unity.

Knight Jacob was a Brotherhood of Steel knight, and later a co-founder of Broken Hills.[1]


Knight Jacob was one of those men and women who swore them, promising to destroy mutants. This put him on a collision course with Marcus, who, following the destruction of Mariposa and the Cathedral, took to the wastes.[1]

Jacob came across Marcus, and 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, people gradually started following them. Marcus led the growing group to the site of a pre-War uranium mining town he knew about from old maps.[1]

There, he and Jacob founded the settlement of Broken Hills about 60 years ago.[2] 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."[3]

Inhabitants of the settlement would honor his memory by naming their children after him, as is the case with Jacob the Chemist.[4][5] 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.[6][7]


Jacob is mentioned in Fallout 2 and Fallout: New Vegas.

Behind the scenes

According to the Fallout Bible, Jacob's exchange with Marcus took place from Summer 2185 until his departure in Spring 2186.[Dev 1]


  1. 1.0 1.1 1.2 Chosen One: "{107}{}{Who are you?}"
    Marcus: "{124}{mcs7}{I’m Marcus. Helped build the place. Now I’m sheriff.}"
    Chosen One: "{125}{}{You helped build this place? That must have been a long time ago…}"
    Marcus: "{128}{mcs8}{Long story. Want it short or the whole thing?}"
    Chosen One: "{130}{}{Hell, I’m not too busy. Let’s hear it all.}"
    Marcus: "{136}{mcs10}{Right...After the Master and the vats were destroyed, I wandered a bit. No place to go. One day got attacked by this fool wearin’ power armor.}"
    Chosen One: "{137}{}{Really?}"
    Marcus: "{138}{mcs11}{That was Jacob, from the Brotherhood of Steel. He’d sworn some oath to destroy muties. We tussled for a while – probably a day or two. After a while, we just started laughing. What was the point?}"
    Chosen One: "{139}{}{Then what?}"
    Marcus: "{140}{mcs12}{We became friends. Headed off together. Then other people started following us. Guess they figured if they weren’t safe with a mutie and a Steel Knight, safe just wasn’t going to happen. }"
    Chosen One: "{141}{}{So you set up here. Why?}"
    Marcus: "{142}{mcs13}{Uranium mine. I knew there was one around from old maps. Now anybody’s welcome here – ‘long as they act right. Others might not think much of us, but nobody’s more free than we are. There ya go.}"
  2. Chosen One: "{107}{}{Who are you?}"
    Marcus: "{124}{mcs7}{I’m Marcus. Helped build the place. Now I’m sheriff.}"
    Chosen One: "{125}{}{You helped build this place? That must have been a long time ago…}"
    Marcus: "{128}{mcs8}{Long story. Want it short or the whole thing?}"
    Chosen One: "{129}{}{Give me the short version.}"
    Marcus: "{133}{mcs9}{Right. Me and a human named Jacob built this place around that old bank about 60 years ago. Anyone’s welcome here, long as they keep the peace.}"
  3. Chosen One: "{143}{}{Wait… you were friends with a guy from the Brotherhood?}"
    Marcus: "{216}{mcs32}{Damn right. Best friend I ever had.}"
    Chosen One: "{217}{}{Yeah, right, you would’ve dipped him just like everyone else.}"
    Marcus: "{219}{mcs33}{Hell, yes, I would've. What a great mutant he would’ve been.}"
    Chosen One: "{220}{}{I don't think he'd be happy to hear you say that.}"
    Marcus: "{222}{mcs34}{(laughs) We had this argument all the time. (sigh) I miss that hard-head.}"
  4. Anti-mutant conspiracy
  5. Chosen One: "{110}{}{What can you tell me about Broken Hills?}"
    Jacob the Chemist: "{148}{}{Why don’t you tell me how you feel about mutants first?}"
    Chosen One: "{149}{}{I hate them.}"
    Jacob the Chemist: "{152}{}{In that case, I’ll give you the real history.}"
    Jacob the Chemist: "{153}{}{A human named Jacob – I was named after him – founded this place. The mutant Marcus came along and forced everyone under his rule. }"
    Jacob the Chemist: "{164}{}{He’s been ruling here ever since the Master was destroyed. He puts down anyone who disagrees with him… or they just "disappear." The place looks civilized on the top of things, but the truth is that it’s a killing ground for bloodthirsty mutants. There's a friend of a friend who had friends who disappeared after speaking up.}"
  6. Courier: "What's the history of Jacobstown?"
    Marcus: "Was a resort Pre-War. I renamed it to Jacobstown after an old friend. Died a long time ago. I figured us mutants needed a place to call our own. Town's far enough away from humans so they don't bother us much. One of these days I'm hoping we can trade with the rest of the wasteland. No more fighting, just... get along."
    (Marcus' dialogue)
  7. Courier: "What's wrong with the Nightkin?"
    Marcus: "Nightkin suffer schizophrenia from the Stealth Boys they're always using. One of the reasons I settled Jacobstown was so they could be cured. While they're in town, the Nightkin aren't allowed to have Stealth Boys so their craziness doesn't get worse. Trouble is the Nightkin don't like being visible, either. They don't take being exposed too well."
