Cain

Cain is a possible player character in Fallout: Brotherhood of Steel and one of three possible choices to be the Initiate, the others being Cyrus and Nadia.

Background
As a mercenary, Cain is a ghoul through and through. Stooped, skeletal, and bony, Cain is a real badass, the kind of guy who upon finding your burning body would roast desert rat over you rather than put you out. When his home, Necropolis, was razed to the ground by the super mutants, Cain took it personally. In an attempt to seek vengeance upon the mutants, he sought out the Brotherhood of Steel and demanded entry. As a somewhat isolationist and anti-mutant order, the Brotherhood was reluctant to grant him admission, but Cain's perseverance was fueled with a grim determination. He was finally given a test of initiation, a suicide mission that should he survive would allow him to become one of the first ghouls ever to join the ranks of the Brotherhood.

Traits
With less strength than Cyrus and less speed than Nadia, Cain's ability to withstand the effects of radiation is what truly sets him apart. Once he has gained the Rad Child skill, He will actually heal himself when coming in contact with radioactive substances.

Appearances
Cain appears only in Fallout: Brotherhood of Steel.
