Sasak was the husband of T'Pel and father of Selek, a distant cousin of Sarek. In 2237, while journeying to the family shrine to honor the Vulcan gods, Selek visits Sarek's home in ShirKahr, where Sarek offers for him to stay with them, to break up his journey. While visiting, Selek's young cousin Spock, prematurely begins his kahs-wan across Vulcan's Forge. Selek follows Spock and is able to save him from death when he and his pet sehlat, I-Chaya, were attacked in the foothills of the L-langon Mountains by a wild le-matya. (TAS: "Yesteryear")
- In reality, Selek was the indentity assumed by Spock when he traveled to his past, through the Guardian of Forever, in order to save himself from otherwise being killed by the le-matya. The names "Selek", "T'Pel" and "Sasak" could possibly be true distant cousins of Sareks family, as it would be illogical for Spock to lie about such facts.
