Liviana Charvanek

Charvanek is the name of a Romulan military commander who, in 2268, was in control of three Romulan Star Empire starships which intercepted the USS Enterprise that had illegally crossed the Romulan Neutral Zone.

She believed that her rise in her people was signified by bringing the flagship of the Federation to Romulus as a trophy. To do so, she attempted to seduce the Vulcan science officer Spock but she herself was captured in turn along with the prototype Cloaking device technology. This would forever scar her as she was taken as a prisoner by Starfleet though she managed to return to her own people in time. (TOS episode: "The Enterprise Incident").

Her aunt was famous commander Ael t'Rllaillieu and she had a cousin in Tafv.

By 2377 she became the head of Romulan intelligence and was situated in the Office of Homeworld Peace. At the time of the Watraii conflict, she abandoned her post and took a squadron of ships to fight this new enemy to the Romulan Empire.

The novel Killing Time refers to her with another name, Thea
