Biography[]
Early Life[]
Born in 2230 (1377 NE), Sybok was the first son of Ambassador Sarek and the Vulcan princess T'Rea, his birth came as a result of the only mating between his parents and his existence was kept secret from his father Sarek as he was married to Amanda Grayson, a Human school teacher, After the death of his mother, Sybok was raised by Sarek as a half-brother to Spock. As a young student, Sybok was considered to be exceptionally gifted, possessing great intelligence, and it was assumed that he would one day take his place among the great scholars of Vulcan. During his studies, Sybok received visions given to him by what he believed to be "God", beginning his journey for a place in Vulcan mythology known as Sha Ka Ree.
However, Sybok rejected his logical upbringing and chose to embrace emotion like his ancestors, believing that the key to self-knowledge was emotion, not logic. When Sybok encouraged other Vulcans to follow him, he was banished by the Vulcan High Council. For this reason, he was considered a V'tosh ka'tur, and eventually, his half-brother was told to avoid Sybok "at all costs."
n 2259 (1405 NE), he was confined to the Ankeshtan K'til Vulcan criminal rehabilitation center, on the third moon of Omicron Lyrae, under the alias "Xaverius" to protect Ambassador Sarek's reputation. Here, agents of the El-Keshtanktil (including T'Pring, Spock's betrothed) attempted to rehabilitate Sybok and other criminals by showing them the true path of Vulcan logic. Around this time, he was romantically involved with Angel, the leader of a band of pirates operating outside of Federation space. Angel sought to free their lover by capturing the USS Enterprise and holding Spock as hostage, using his relationship with T'Pring as leverage. However, this plan ultimately failed thanks to the efforts of Spock and Christine Chapel.
