The Vulcan Science Council was an agency of the Vulcan High Command during the 22nd century. T'Pol belonged to the Science Council early in her career. In 2152, T'Pol explained to Jonathan Archer that her encounter with Ambassador V'Lar, during the Ka'Tann Conference, inspired her to choose a direction in her life. This path led her to the Vulcan Science Council and eventually to her posting aboard Enterprise. (ENT: "Fallen Hero")
