Valkris

Valkris.

Valkris was a Klingon operative who was romantically involved with Kruge.

In 2285, she obtained classified Federation data regarding the Genesis Device that she carried with her aboard the vessel Merchantman.

Valkris was killed when the ship was destroyed by Kruge's Bird-of-Prey, after the Klingon commander learned that she had seen the data. Moments before her death, however, Kruge vowed that Valkris would be remembered with honor. (Star Trek III: The Search for Spock)

Valkris was played by actress Cathie Shirriff. According to the script, she was described as an "exotically beautiful woman of epic proportions and mystery."

In the novelization of Star Trek III, we learn than Valkris has an older brother, Kiosan. When she was chosen to lead her family's house over him, he fell into dishonor, and his behavior so tainted the family that she was forced to disown him. She undertook the mission to steal the Project Genesis data because she knew Kruge would kill her afterwards in a manner that would restore her family honor. There is no evidence of a romantic involvement with Kruge in the novelization; he admires her as a fierce warrior, and she "loves" him because he is her meal ticket to redemption. This point was not make clear in the film, most likely for pacing purposes.
