Vault 13 Overseer

Overseer Jacoren is the overseer of Vault 13 in 2161.

Background
The Overseer was committed to the Societal Preservation Program and the 200-year isolation experiment on Vault 13. When Vault 13's only functioning water chip became damaged, he is forced to send the Vault Dweller into the wasteland to scavenge a replacement.

Despite his strict nature, the Overseer of Vault 13 truly fond of his community. Fearing for their curiousity and the integrity of the Experiment, the Overseer banishes the Vault Dweller from 13 upon their return. Ironically, his plan backfires and many more follow the Vault Dweller into the wasteland. Those who remained would apprehend the Overseer and sentence him to death for his role in the exodus.

Quests

 * Find the Water Chip: Vault 13's water purification chip is broken and has stopped working. Jacoren tasks the Vault Dweller with finding another one.
 * Destroy the source of the Mutants: The mutant army poses a great threat to Vault 13. Jacoren wants the Vault Dweller to neutralize them to ensure the preservation of the vault.
 * Destroy the Mutant leader: Along with destroying the army, its leader must be killed as well.

Effects of player character's actions

 * If the player character decides to side with the Master and be turned into a super mutant, during the end cutscene showing the destruction of Vault 13, the overseer can be seen attempting to hold off the invaders with his minigun-equipped overseer's chair, before being overrun and brutally beaten to death by two of the mutants.
 * With the Bloody Mess trait, the Berserker or Childkiller titles, or a low reputation, right after the overseer's goodbye speech at the end of the game, the Vault Dweller will automatically put away any held weapon, draw a pistol and shoot the overseer in the back. It is also possible to kill Jacoren by initiating combat just after his speech, and putting him down with one or more shots. If Jacoren is killed, he falls to the ground with his internal organs hanging from his body, with both his left arm and left leg severed and his ribcage exposed, whereupon he uses his remaining arm & leg and crawls in an attempt to move to the vault door, which he does reach but is unable to open before ultimately succumbing to his injuries.

Other interactions

 * If the player has an Intelligence below four, Jacoren will explain things in a slow and simple manner. At times getting frustrated over doing so.
 * If the player speaks to Jacoren repeatedly and tells him they have not found a water chip, he will ask if the player needs more help. The player can request additional supplies to receive two stimpaks and 48 10mm JHP.
 * After the goodbye speech, the player may murder the Overseer.

Inventory

 * In the Overseer chair.

Appearances
Jacoren appears only in Fallout, as a talking head.

He was also to appear in the canceled Fallout movie, where he was to be revealed as the founder of Vault-Tec and the man who started the Great War.

Behind the scenes

 * I always thought of Fallout's story of drawing straws was something the Overseer thought of. "Look, someone has to go outside, and they may die out there, so let's draw straws". Someone, probably not the Overseer since he wouldn't have gone outside no matter what, demanded that EVERYONE draw a straw in order to be truly fair. But to be honest, the vault dwellers were simply terrified of going outside, and terrified people do not always make the wisest decisions. Anyway, when big dumb Larry drew the straw, maybe the Overseer saw a way to rid their limited gene pool of some really bad alleles. - Tim Cain at DAC forum
 * At the end of the quest Trouble on the Homefront in Fallout 3, Amata has the same quote as Jacoren saying, "I'm sorry. You're a hero... and you have to leave," right after she exiles the Lone Wanderer from Vault 101. However this is only if the Lone Wanderer kills the overseer, if they convince the overseer to allow the vault to open, she will be thankful for their help but will reluctantly exile them due to the other vault residents blaming them for the problems in the vault.
