Sybok

Sybok was a Vulcan male who lived in the 23rd century. He was the son of Sarek and the Vulcan princess T'Rea, and would later become the half-brother of Spock.

Sybok was born in 2224, his birth was initially kept a secret from Sarek, but he later discovered the truth. His mother T'Rea ascended to become High Master of Gol, and at this point the marriage had to be annulled. Later, when T'Rea died Sybok went to live with his father Sarek and his family, which included Sarek's wife Amanda and their son Spock. (TOS novel: Sarek and TOS novelisation: Star Trek V: The Final Frontier).

As a young man, Sybok was exceptionally gifted and possessed great intelligence. Many on Vulcan assumed that one day Sybok would take his place among the great scholars of that world. Sybok instead decided to become a revolutionary, and sought knowledge and experience forbidden by Vulcan beliefs. Rejecting the idea of pure logic, Sybok instead preferred to balance logic with emotion, and embrace what Spock would later term the animal passions of their ancestors.

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. Later, he would break into the vault where his mother's katra was being stored in an attempt to learn more about Sha Ka Ree. When that crime was discovered, Sybok was banished from Vulcan.

In 2287, Sybok's came to Nimbus III. Using an ancient Vulcan technique where he forced others to confront their deepest pains and draw strength from it, Sybok gathered a group of loyal followers, which he called the Galactic Army of Light. Sybok's forces then stormed Paradise City, which they easily captured.

Sybok then forced the three representatives of the city - the Romulan Caithlin Dar, the Klingons General Korrd, and the human St. John Talbot to face their deepest pain. He then had Dar proceed to send a transmission out stating that they had been kidnapped and Sybok's group had taken over the planet. As Sybok hoped, this drew the attention of the Federation, who sent the [[USS Enterprise (NCC-1701-A) to the planet. Captain Kirk and his crew initated a rescue attempt, which failed when the representatives all pulled their weapons on Kirk.  Sybok and a small number of his followers were taken on board the Enterprise, and hijacked the vessel.  Sybok took the Enterprise to the location where his visions lead him, beyond the Great Barrier.

Upon landing on Sha Ka Ree, it was revealed that Sybok was led astray by the One, which instead of a God was instead a malevolent entity imprisoned on the planet, seeking a starship to gain its freedom. Realizing what he had done, Sybok attempted to save the crew of the Enterprise by sacrificing himself at the altar of his god. (Star Trek V: The Final Frontier)
