Mason (Fallout 2)

Mason is Louis Salvatore's right hand man, who stands outside of his room, carefully guarding it and preventing anyone from entering, unless requested by Louis. While the player must go to Louis to receive each mission, it is Mason who briefs you on the details, a practice unique to the Salvatores. Mason holds the unique Mirrored Shades, and is the only NPC to drop Metal Armor Mark II upon death.
