Syrran was a Vulcan who founded a small group called the Syrrannites, who were dedicated to returning the Vulcan people to what they believed to be the true teachings of Surak. 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.
