Luckily, they were nursed back to health in Goodsprings, starting the story of New Vegas.
Robert House - Robert Edwin House, typically known as Mr. House, is the enigmatic ruler of New Vegas. He is displayed as an image on a computer screen, however, he is actually what is essentially a corpse being kept alive, in a decontamination pod deep in his casino, the Lucky 38.

Aaron Kimball - President Aaron Kimball is the current president of the New California Republic in 2281.

In 2273, he became a representative of the Hub. Later on, in the same year, Kimball ousted incumbent Wendell Peterson as president of the New California Republic and won reelection in 2278. Kimball secured his position with his hardline stances on political issues, despite his failures, such as the Mojave Campaign, an elongated, seven-year annexation of the Mojave Wasteland.

The Strip FamiliesThe Chairmen - The Chairmen and their casino, the Tops, embody an ancient "cool" aesthetic of Vegas, plucked from Mr. House’s historical data banks. Before The Strip’s renovation in 2274, the Chairmen were a warrior tribe named the Mojave Boot-Riders. The Boot-Riders were contacted by a Securitron that Mr. House was using to relay his proposal for their tribe to join the tribal workforce that he was putting together to start the renovation and reconstruction efforts for New Vegas. The Chairmen became the first tribe brought to the Strip. Swank admits that, "Without Mr. House, we'd still be wearing gecko skins, poking around the ruins with pointy sticks and scalping people for giggles."
The Omertas - The Omertas are one of the Three Families of New Vegas. Before the formation of the Three Families, the Omertas were known as the Slither Kin, however, their employment under Mr. House required the shedding of their old tribal skin for the stylings of old-world mafiosos. In 2281, they operate the Gomorrah club and casino on the New Vegas Strip in the Mojave Wasteland.
The White Glove Society - The White Glove Society is one of the Three Families, responsible for the operation and maintenance of the Ultra-Luxe casino on the New Vegas Strip in 2281. The White Glove Society is a former tribe employed by Robert House to run and maintain the Ultra-Luxe casino and hotel.

Despite some odd looks at first, she got top marks during her training and received an officer's commission at the age of 17. During this period, she took part in operations against various gangs plaguing the NCR territory, sharpening her skills on the likes of Jackals and Vipers, as well as surviving four tours of duty against the Brotherhood of Steel in California, and is widely considered to be one of the most skilled and accomplished commissioned officers in the NCR Army. She is a noted conservative in military matters, favoring strength and determination over cunning and diplomacy. Chief Hanlon says that she is "better at making graves than making friends."
James Hsu - Colonel James Hsu is the commanding officer of the New California Republic Army's Camp McCarran and New Vegas garrison units in 2281. He is found at Camp McCarran terminal building, in his office in the northern section on the building's ground floor. A level-headed, competent officer of the New California Republic Army, Colonel Hsu is the commanding officer of most of the New Vegas garrison and the nexus of NCRA's military efforts in the Mojave, Camp McCarran. Unlike Colonel Moore or General Oliver, Hsu is far more sympathetic to the locals and less of a war hawk. He is also in charge of water and power distribution in Freeside. He is a staunch believer in diplomacy over the force of arms and cares a great deal about the soldiers under his command, working steadily to better their situation.[4] As it stands, he's stuck in a holding pattern managing troop rosters and trying to contain the Fiend threat on the western flank.

Colonel Royez is in charge of the NCR camp on the Long 15, managing supplies between California and the Mojave Outpost.

Dennis Crocker - Dennis Crocker is the ambassador to New Vegas for the New California Republic in 2281. His full title, according to the note written to the Courier, is "Ambassador Extraordinary and Plenipotentiary" of the Department of State. Ambassador Crocker began his political career as a mayor more than 20 years ago in NCR, and worked his way up through the ranks. He was the head of Kimball's campaign for his successful run for NCR council, which he attributes to why he has his current position. Crocker is a strong believer in diplomacy and hopes to unite the Mojave Wasteland under the NCR peacefully. However, his work has made very little progress since Mr. House refused to even meet him in person after signing the New Vegas Treaty.
