Jaime

 is a crazed ghoul situated on the lowest level of the Dunwich Building and can be initially found worshipping a strange Obelisk alongside a group of several Feral Ghouls.

Jaime is armed with a Chinese Assault Rifle, but is very physically weak (about on par with a Wastelander civilian in terms of durability). Killing him earns the player positive karma and, if the Lawbringer perk has been acquired, Jaime also drops a finger. To avoid positive karma, Jaime can be mezzed with the Mesmetron which will result in the feral ghouls attacking and killing him. This will require the player to wear the Ghoul Mask.

Biography
Parts of Jaime's Personal Journal can be found as audiologs spread throughout the building. The transcripts reveal that he was a traveler who set out searching for his father after he left him alone in a hospital and "went crazy" after acquiring a mysterious book. Jaime tracked his father south from an unknown location across vast distances.

He eventually fell in with another group of travelers who, as it turns out, were violent raiders (why they did not immediately attack is unclear, but if they were to kill everyone they came across, they would never recruit new members.) However, it is not long until, in one of the logs, they apparently killed a family for a "sack of rotten vegetables." Jaime secretly resolved to get away from this dangerous group as soon as possible.

The opportunity to escape presented itself when the raiders prepared to attack a group of traders. Jaime turned on the raiders -- earning the thanks of the traders. Grateful, the trader group told him the direction they last saw his father head off. Jaime followed his father's trail (marked by snares his father had set for food) to the Dunwich Building. He eventually found and/or killed his father who had seemingly mutated into a ghoul. In his audiologs, he recalls hearing the raiders tell "spook stories" about "zombies" inside, which were apparently true (Jaime had never encountered a Ghoul before this point*). Afterward, Jaime picked up a strange book his father had been keeping and decided to rest against an unusual obelisk in the bottom of the building. Upon awakening, he had begun the process of mutating into a ghoul due to the radiation emitted from the obelisk (you can hear him mutating on the Jaime's Personal Journal Entry 09).

Behind the scenes
The plot line is a/an homage to H.P. Lovecraft. The book referred to in the tapes is the Krivbeknih, (around which a quest is based in the Point Lookout DLC called The Dark Heart of Blackhall, which is given to you by Obadiah Blackhall) which is a reference itself to various tomes and books within the Lovecraft mythos, most notoriously, the Necronomicon. As well, the building, Dunwich Building, is a reference to "The Dunwich Horror," which is a short story by Lovecraft. The name "Dunwich Borers" is also a dead giveaway.
