"Vulcans once produced individuals with the capacity to use multiple psi powers with terrible effectiveness, in civilian life and battle. Most of these gifts are emotion based and were lost once most of the population started following the Teachings of Surak. Many Vulcans still bear the genes for the talents but they rarely become full-blown. If they do most choose to join the Temples and Monasteries at Seleya and Gol; to control and hone their abilities."
