Syrran was the Vulcan leader and namesake of the small dissident group known as the Syrrannites, who were dedicated to returning the Vulcan people to what they believed to be the true teachings of Surak. He was considered by Stel to be a "dangerous zealot." (ENT: "The Forge")
In 2137, he discovered a katric ark containing the katra of Surak, and took Surak's katra into his own mind. When Syrran traveled, he assumed the name "Arev", which meant "desert wind" in Vulcan.
By 2154, Syrran had gathered a number of followers, who congregated at the hidden T'Karath Sanctuary, where Syrran hoped to find the Kir'Shara. That year, Arev encountered Jonathan Archer and T'Pol in Vulcan's Forge, while the two were attempting to track down the Syrrannite base. Arev was killed by an electrical discharge from a sandfire storm. His last act was to transfer the katra of Surak to Archer, leaving the Starfleet captain to complete the mission he began.
