Omertas The Omertas are a in the Mojave Wasteland in 2281 . Background . A highly organized and deadly group of mobsters , the Omertas control the Gomorrah casino , a sleazy vice den on a grand scale , and as such embodies the ruthless exploitation beneath the glitz and glamour of the Strip ' s neon signs . They also control all prostitution that goes on around the casino . Male residents at The Tops remark that ' the broads over at the Gomorrah look better ' . While by outside appearances the Omertas seem content with their lot , the family ’ s penchant for treachery and murder is alive and well , and the tribe ’ s leadership is collaborating with Caesar ’ s Legion to bring about the Strip ’ s downfall . Prior to being recruited by Mr . House , the Omertas were a wasteland tribe known as the Slither Kin . A tribe known for the practice of luring unsuspecting travelers into their camps before drugging them , then murdering or enslaving them , sometimes holing up in a stronghold for years , other times leading a nomadic existence in restless pursuit of their next big score . The Omertas have just one rule : never betray the family . Everything else is permitted . Apparently the viciousness of the Slither Kin appealed to Mr . House by reminding him of certain criminal elements that once operated in pre - War Las Vegas . Organization . The Omertas and the Gomorrah casino are run by Nero and his right hand man , Big Sal . Cachino is a small time " underboss " within the family and is put in charge of menial tasks , as well as anything that the head of the family needs taken care of that they don ' t have time to see to themselves . As the Omerta name suggests , they do not readily give out information , or go into detail about the family ' s dealings with anyone not of the family . Breaking this code of silence is dealt with , swiftly and severely . The Omertas are obsessed with power and the ability to control people to meet their needs . They are also very adept at finding ways to squeeze a quick or two out of any situation . This is evident in the fact that they get their new " employees " hooked on free chems , and then start charging for each additional fix while simultaneously taking a cut of the caps the " employee " has earned . Keeping the prostitutes hooked on chems keeps them dependent on the Omertas , and keeps them under their employ while ensuring they remain docile and manageable . Relations with the outside . The Omertas only care about protecting or improving the power they have at their command . Showing a facade that they appear to be perfectly content running the Gomorrah , the Omertas have entered into an agreement with Caesar ' s Legion to attack The Strip at the same time the Legion makes their assault on Hoover Dam . Putting more stock in Legion propaganda than the management practices of Mr . House , and wanting to use the Legion to springboard their power base , coupled with their confidence that the second Battle of Hoover Dam will draw the attention of Mr . House ' s Securitron s , the Omertas believe they will have no problem taking over The Strip . The Omertas make sure to stay away from dealings with the New California Republic , ( despite their best customers being troopers and citizens of the NCR ) , feeling like the institution of NCR laws and taxation will have a severe hindrance on how they conduct business . The Omertas don ' t have any other business or exposure to the other tribes and factions of the Mojave Wasteland , it is mentioned by the Gomorrah receptionist , and Papa Khan that the Omertas along with the rest of what was to become the Three Families , had a war with the Great Khans .
