Valeris

Valeris was a female Vulcan who lived in the 23rd century.

Valeris enlisted in Starfleet at some point in the 2290s. Captain Spock, after meeting her, decided that she was a good candidate to replace him and thus watched over her career. As part of her first training cruise onboard the USS Enterprise (NCC-1701-A), she was supervised by Saavik. Despite Saavik's belief that Valeris was arrogant and bigoted, she decided to give her a full recommendation out of loyalty to Spock. She eventually became the first Vulcan to graduate from Starfleet Academy at the top of her class. 

In 2293, Valeris was a lieutenant, but wore the uniform of a trainee lieutenant commander. She requested an assignment as helmsman aboard the USS Enterprise when that vessel was assigned to escort Gorkon, chancellor of the Klingon High Council, to Earth.

Valeris was involved in the Khitomer conspiracy, which tried to sabotage the Khitomer Conference between the Klingon Empire and the United Federation of Planets in 2293. Her involvement in the plot stemmed from a resistance to the changes peace between the Federation and the Klingons would bring. She contributed to Captain James T. Kirk and Dr. Leonard McCoy's imprisonment by providing the Klingons Kirk's personal log about how he disliked them for the death of his son. She also killed the two officers who killed Chancellor Gorkon, using a phaser at point-blank range, to avoid alerting the rest of the crew, who were searching for evidence about the conspiracy aboard the ship.

However, Valeris made a mistake when she was tricked into thinking that the men she killed were still alive, which was actually a trap to expose her. Spock was able to retrieve information from Valeris by using a forced Vulcan mind meld, the conspiracy was uncovered and the assassination of the Federation Council President was prevented, thereby saving the Khitomer Conference and paving the way for nearly 100 years of peace between the Klingon Empire and the Federation.

Lieutenant Valeris was taken into custody and later charged with treason. She was court-martialed and sent to the Federation maximum security prison on I'Tana IV.

She later escaped with the help of a mysterious accomplice known only as Shadow.
