(Played by Kim Cattrall)

Vulcan
Starfleet Officer who plotted with others to assassinate Klingon Chancellor Gorkon in 2293. Lt. Valeris had been the first Vulcan to graduate at the head of her Starfleet Academy class, and had been mentored by Spock. Her involvement in the plot stemmed from a resistance to the potential changes brought by peace between the Federation and the Klingon Empire. After Spock deduces their shipboard mole and uses a Vulcan mind meld to force the truth from her, Valeris was arrested at the Khitomer Peace Conference and later charged.
