Hugo

Hugo is a former raider that can be found dead in Hugo's Hole in 2287.

Background
Hugo was a member of the raider posse living in Dunwich Borers, but, for unknown reasons, he left the group and moved to a makeshift stronghold nearby. When the Sole Survivor first arrives to his home, a gunshot can be heard and, upon making their way past the booby traps in the place's entrance, they find Hugo's corpse on his bed, apparently having committed suicide. Next to his body are a few things of interest, most prominently as a holotape, Dunwich - Hugo's struggle. Listening to the tape reveals that Hugo was under the influence of some kind of supernatural force that he referred to as "it". He plotted to go back into the quarry and kill all his former gang mates, but "it" kept him from doing so and, ultimately, compelled him to kill himself. The entity is implied to be the same one that pervades Dunwich Borers and had driven the raiders there insane as well.

Appearances
Hugo appears only in Fallout 4.

Behind the scenes

 * The nearby Dunwich Borers and Hugo's tape as well as The Dunwich Building in Fallout 3 are all Lovecraftian references to Lovecraft's The Dunwich Horror.
 * The being he refers to is probably one of the great old ones I.E. Cthulhu who turns people insane by simply seeing him.
