Kuvak was a Vulcan politician.
Also that year, Kuvak opposed V'Las' plan to invade Andoria because of Xindi technology the Andorians supposedly possessed. Even after the Andorians discovered the assault fleet, V'Las ignored Kuvak's calls for withdrawal.
In 2155, Kuvak served in the new government under T'Pau as one of her senior aides. He was instrumental in funneling military aid to Haakona and in stonewalling T'Pol's attempts to contact T'Pau. (ENT novel: Beneath the Raptor's Wing)
After T'Pau stepped down as First Minister of the Confederacy of Vulcan upon the founding of the United Federation of Planets, Kuvak succeeded her as the leader of Vulcan's civilian government, a position he still held as of 2165. (ENT novel: Uncertain Logic)
