Sakkath was a Vulcan male in the 24th century United Federation of Planets. He possessed a certain control of telepathy which allowed him to help other Vulcans.
He served as a personal assistant for Ambassador Sarek in the 2360s. It became clear to him and others that Sarek was losing emotional control over time due to Bendii Syndrome. Discreetly, he used his abilities to strengthen his mental discipline and conceal the effects.
In 2366, he accompanied Sarek aboard the USS Enterprise-D during the Legaran Conference. This mission was particularly stressful to Sarek, and, seeing that his condition worsened beyond his abilities, Sakkath was forced to consider alternatives. He innocently inquired of Data about Jean-Luc Picard's ability to conduct the conference, explaining he was only being thorough. Data later came back to him and confronted him about whether his loyalty to Sarek or the Federation was more important. When Sarek was later confronted by Picard, Sarek directly asked Sakkath what he was doing, and learned the truth.
After the conference, Sakkath continued to help Sarek like he did before on the USS Merrimac on the way back to Vulcan. (TNG: "Sarek")
Sakkath was played by actor Rocco Sisto.
