The Vulcan purists were a group of Vulcans on the planet Ni'Var in the 32nd century. One of its sects was led by the young V'Kir.
In 3189, the Vulcan purists were represented by Peer V'Kir at Commander Michael Burnham's T'Kal-in-ket. (DIS: "Unification III")
The following year, the purists favored isolationism following the appearance of the Dark Matter Anomaly. They demanded that President T'Rina include a logical framework to hold the Federation accountable should Ni'Var resume its membership. As their support was vital to her political coalition, T'Rina requested an unprecedented exit clause amendment to Ni'Var's membership agreement. (DIS: "All Is Possible")
