Veronica van Dune

Veronica Van Dune came from Diamond City in the Commonwealth, being a decedent of one of Vault 75’s dwellers (which was making child-soldiers before said child soldiers rebelled). She had witnessed many things growing up the city, including but not limited to: the Sole Survivor of Vault 111 coming to the city, discovering the Institute is a real threat, the reformation of the Minutemen, the Brotherhood coming to the Commonwealth, and the destruction of the Institute. Once she was old enough, she joined the Minutemen, serving as a markswoman and an animal handler. She would also be part of the Railroad, helping Synths escape persecution from the Brotherhood. Eventually, one particular Synth would come to the Railroad and need a specific form of help: they needed to be escorted to Quad City. Victoria would be the one to volunteer for this.
Before she went on her trip, Veronica would be given a Pip-Boy, belonging to her Vault 75 ancestor, to give her a better means to manage herself and travel to Quad City. The trip would be long and challenging, but her survival skills, weapon training, and knowing how to talk down both people and creatures allowed her to travel largely safely. The two would unwittingly uncover and “crack open” Vault 63, a still active Vault in Indiana, which they utilized for rest and resources.
When they arrived at the Quad City region, they were attacked by an Enclave patrol, who would have nearly killed her and her escortee had Quad City forces not intervened. Turns out, it was the Vault Cracker Society that escortee was escaping to. They were thankful for her delivering the package safely but took immense interest in her when they discovered she’s a decedent of Vault 75 and had cracked open Vault 63. They convinced Veronica stay for a while longer to gather information from her and after much negotiation, initiate Victoria as a member of the Vault Cracker Society. She’d quickly garnish a reputation as talented, charismatic, and way prettier than what most surface-dwellers should look, most commonly teamed up with Vault 115 Dweller Lif Cassel (and his brother, Ask Cassel) and the BOS "Steel Hunter" Titiana.
