Vault-Tec Rep

The Vault-Tec representative, more commonly known as Vault-Tec rep, was a door-to-door salesman working for Vault-Tec in 2077. After the Great War, he became a ghoul, eventually settling down at Goodneighbor's Hotel Rexford in 2287.

Background
The Vault-Tec rep was responsible for notifying and enrolling local families into Vault 111 prior to the Great War. The rep was doing his rounds in the neighborhood of Sanctuary Hills in the final hours prior to the War and called upon the Sole Survivor's family on that fateful morning, making it known that they had been selected for entry into Vault 111, due to Nate's loyal service to the United States in the Sino-American War.

When the air-raid sirens activated, the rep approached the Army officer guarding the gate, forcefully attempting to proceed into the vault his employer had constructed. His efforts were fruitless however, as he was driven off when a power armored soldier threatened to open fire.

For his contributions to the operation to recruit local residents for entry into the vault, the rep was to be rewarded a pack of steak knives. This never happened due to the onslaught of the nuclear war.

Post-War
Despite being unable to secure a spot inside Vault 111, the Vault-Tec rep managed to survive the nuclear exchange. To his surprise, the radioactive fallout did not kill him, but mutated him into a ghoul.

The next 200 years would prove difficult for the former salesman. His once-valuable sales experience was of little use in the anarchic aftermath of the war, and his status as a ghoul earned him scorn and animosity from un-mutated survivors. He was forced to live as a drifter and vagrant, squatting in various communities, where he was constantly taunted and threatened by the residents.

Eventually, he discovered Goodneighbor, soon after being denied residence in Diamond City. This urbanized community located right in the heart of downtown Boston was a far cry from Diamond City, having been founded by those exiled from the green jewel's walls. While this earned him a warmer reception than he was used to in a new town, it did little to ease the trauma of the past centuries, and he generally confined himself to his room at the Hotel Rexford. It was some time after this that he was reunited with the Sole Survivor.

Quests

 * War Never Changes - Interacting with the Vault-Tec rep prompts the player character to choose their SPECIAL stats for the first time and enter a name for the Sole Survivor.
 * Familiar Faces - He can be recruited and sent to a settlement.

Other interactions

 * When the Sole Survivor talks to him about Vault 111, he will say that he didn't know anything about the Vault's cryogenic stasis and that he was supposed to "win a pack of steak knives," a reference to the popular stage play and film Glengarry Glen Ross by David Mamet. The knives were, ironically enough, the second place prize in the sale contest.
 * Piper and MacCready like recruiting the Vault-Tec rep. Hancock, Strong, and Cait dislike recruiting him. Danse will hate it if you recruit him.
 * Cait "loves" when answering his question with "blood of your enemies."
 * He can be assigned as a level 4 merchant for the trading emporium and will start selling rare junk items, such as the clean broom, military ammo bag and military grade duct tape. He also sells a unique armor piece, the Apocalypse left greave.
 * If recruited and sent to a settlement, the Vault-Tec rep will say lines about how Vault-Tec kept him in the dark about their experiments.
 * After being sent to a settlement, he will continuously repeat similar dialogue sentences about his hardships over the years, the Sole Survivor having it easy and that things will be looking up.
