Jaime

 is a crazed ghoul in the lowest level of the Dunwich Building and can be found worshiping a strange Obelisk alongside a group of several Feral Ghouls in 2277.

Background
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 (the Krivbeknih). 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.) It was not long until they 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 where his father headed. Following his father's trail (marked by snares his father had set for food) Jaime headed to the Dunwich Building. He eventually found and possibly killed his father who had, by that time, become 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 at the end of Jaime's Personal Journal Entry 08 and throughout Entry 09).
