Trefayne

From Memory Alpha, the free Star Trek reference.

During Kirk's visit to Organia in 2267, Trefayne was one member of the Council of Elders. Described as "quite intuitive" by Council spokesman Ayelborne, Trefayne knew that eight space vehicles had assumed orbit around the planet before Spock was able to verify this with his tricorder. Additionally, he knew that these vehicles were beaming men to the surface, and that these men carried many weapons. Although Trefayne's pronouncements, and Ayelborne's confidence in them, provoked Kirk's curiosity, Kirk had more important concerns, and never investigated. This was, although he did not then realize it, Kirk's first clue that there was more to the Organians than met the eye. (TOS: "Errand of Mercy")

Given Claymare's statement that no one had died on his world in uncounted thousands of years, it is reasonable to assume that Trefayne is still alive.

Trefayne was portrayed by David Hillary Hughes.
