Fens Phantom

The Fens Phantom was a Boston-based serial killer heard in the dear detective tapes, operating out of the Fens Street sewer in 2287.

Background
The Fens Phantom was a prolific serial killer in Boston before the Great War, who was presumed to have claimed dozens of Bostonian lives, displaying their corpses in the city sewers, where he claimed as a 'base of operations' of sorts.

Motives
The Phantom shows heavy frustration with society and societal norms, and how he views people as fake and transparent, using holotapes as a means to spread his vision to those that would listen. He voices this in his second detective holotape:

Appearances
The Fens Phantom appears only in Fallout 4.
