Sporting facial tattoos for identification, Vector One belonged to a cohort of navigators affiliated with the Navigators' Guild operating in the Unknown Regions. During 19 BBY, Mitth'raw'nuruodo, a Senior Captain of the Chiss, known by his core name as "Thrawn," along with the Caregiver Mitth'ali'astov ("Thalias"), embarked on a voyage to Primea, the capital planet of the Vak Combine. They traveled aboard a Garwian diplomatic ship, masquerading as an Artistic Master and his associate. On the vessel's bridge, Thalias informed a Garwian officer that she was tasked by her master with committing to memory the facial tattoos of the navigators. The Garwian officer responded by stating that her master was misinformed, as only the Vector One navigators possessed such tattoos, while a Pathfinder accompanied their current voyage.
The novel Thrawn Ascendancy: Chaos Rising, published in 2020 and serving as the initial book in Star Wars: The Ascendancy Trilogy by Timothy Zahn, featured mentions of Vector One navigators.
