S'chn T'gai Skon was a Vulcan male who lived during the 22nd century. He was the son of Solkar, the father of Sarek and the paternal grandfather of Spock and Sybok. Both his father and son served as the Vulcan Ambassador to United Earth.
In the mid 2150s, he was a mathematician who was recruited by the Cochrane Institute of Alpha Centauri to participate in the testing of a prototype transporter. (DS9 - The Lives of Dax short story: "Dead Man's Hand")
During the Earth-Romulan War, he, Tobin Dax, and Pell Underhill were part of United Earth's Warp Seven Program in order to give Earth an advantage against the Romulan Star Empire. (ENT - The Romulan War novel: Beneath the Raptor's Wing)
In 2157, Skon took part in a test for countermeasures to the Romulan telecapture device that was unsuccessful. On that same day Skon was sent home to Vulcan and his compatriots Dax and Underhill took part in a successful test. Eric Stillwell revealed that the first test had been faked in front of Skon so the Vulcans wouldn't find out about Earth's new defenses. (ENT - The Romulan War novel: To Brave the Storm)
For most of his life Skon was married to T'Rama. (ENT short story: "A Girl for Every Star") The couple eventually had a son, Sarek, who was born in 2165. (TOS movie: Star Trek III: The Search for Spock) Sarek was the elder child and the couple had another son called Silek. Silek became somewhat of a rebel and had chosen to defy tradition by not entering the diplomatic service leading to him being declared a Ktorr Skann; thus the formal ties between father and son were severed with Silek being forbidden to return home. It was only after Skon's death that Silek was accepted back to the household by his mother. (TOS novel: Demons)
