This is an odd faction/family in New Vegas. We know a few things about them: - they deal in energy weapons - they're rivals of the Gun Runners - they're from Redding and there a lot of them, most of whom are half siblings from their mother, Tiaret Van Graff's many husbands. The thing is, they were a new addition in New Vegas and there's really nothing else to connect them to previous games other than Redding which wasn't even a prosperous community when Chosen first got there. My theory? Tiaret Van Graff grew up in Redding, possibly making her living in the Malamute presumably where most of her kids from many different fathers were made. She wanted a better life and took all her kids to New Reno where she met Louis Salvatore. We know nothing about Salvatore except he's a dying old man and head of the most feared faction in the city at the time since Energy weapons weren't common. Maybe he once had a family, maybe he inherited everything from his whatever the case one day he encountered Tiaret and all her kids and saw that as the last opportunity to have some sort of family surrounding him on his death bed so he took them all in. Inevitably, they would all learn the trade and inherit his wealth when he passed. Thoughts???
