Tandi " De facto " president - for - life Tandi ( born in 2145 ) is the leader of Shady Sands . In 2161 , she still resides in the same town , unaware of her future role in society . Destined to be a founder and second president of the New California Republic , she would go on to become one of the most influential people in the entire post - war world . Background . Early days . She is the daughter of Aradesh , and is destined to one day replace her father as the town ' s leader . Currently , she is bored stiff with the place , a little in awe of people who ' ve seen something of the outside world , and a bit naïve . She ' s a tomboy with a sharp mind and quick wit , a free spirit who is not afraid to speak her mind . Tandi was one of the most important people of the West Coast in the 23rd century . From her early years she displayed an uncommon strength of character and liveliness , complementing her good looks ( six feet tall with raven black hair and a dark complexion ) . In 2161 , at the age of sixteen , she met the Vault Dweller , a figure who would inspire her for years to come with their charisma and skill , exemplified by ridding Shady Sands of the radscorpion plague . The impression was only reinforced when Tandi was kidnapped by the Khans during their raid and the Vault Dweller rescued her from the raiders . Inheritance . Tandi helped her father expand Shady Sands , laying the foundations for the New California Republic . When her father disappeared searching for Vault 13 , she rose to power , and soon the town grew substantially as she opened trade routes with Junktown and the Hub . This was something her father had been reluctant to do , despite the obvious advantages . With a strong economy and Tandi ' s determined guidance , Shady Sands soon dominated the brahmin trade and eventually , the first states of the NCR emerged , slowly merging into a standalone political entity with help from the Brotherhood of Steel , which remained out of the power structure for the time being . Tandi succeeded her father as the President of the Republic and from then on ruled the NCR alongside the Congress . She was focused on expanding the state , to bring peace and stability to the wastes . Her ideals long since replaced by pragmatism , she was not above forging a deal with New Reno to bully Vault City into joining the NCR and supplying it with their superior medical technology . Closing on 100 years of age in 2241 , Tandi remained acting President , still retaining her wit and youthful fire . Dementia and other ailments of the elderly seemingly failed to sink their hooks in her . President Tandi died in 2248 at the age of 103 , after a 52 - year presidency . She was succeeded by her Vice - President , Joanna Tibbett . Her legacy lived on , however , and she remains the most popular NCR president to date . Family . Tandi ' s father is Aradesh , the leader of Shady Sands . Her mother ' s name is unknown .
