Kalev was the Chancellor of the Coridan government in 2151.

That year, she invited Captain Jonathan Archer and T'Pol of the NX-01 Enterprise to visit her planet 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 cannot 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")
