Kalev was the Chancellor of the Coridanite government in 2151.
That year, she invited Captain Jonathan Archer and T'Pol of Enterprise NX-01 to visit Coridan and take a tour of the Coridan shipyards. However, she did not inform them that her government was engaged in a civil war, and the two Enterprise officers were captured by rebels and held for ransom.
Afterward, she informed the rest of the Enterprise crew of the situation, claiming it to be an "isolated incident", and that the crew must not give in to any demands from the rebels. For unknown reasons, Kalev offered no assistance to the subsequent rescue effort. (ENT: "Shadows of P'Jem")
Kalev was played by Barbara J. Tarbuck.
In the first draft script of "Shadows of P'Jem" (written while the episode had the working title "Untitled Andorians Return"), Kalev was once referred to (in dialogue) as holding the title of "Supreme Chancellor", termed a "Chancellor" on all other occasions. She was also characterized as being the leader of an army, and she urged the Enterprise crew to give the rebels whatever they wanted, in complete contrast to what she advises in the episode itself.
