The Battlestar Libran is the main ship in Wes Imlay's Flight of the Libran story. Built during the First Cylon War as a Virgon Class Dreadnought Warstar, she and her sister ship Gemenon, was taking into shipyard and refitting/conversion into Battlestar because of the need for more Battlestar to fight the Cylon. This led to a the Gemenon Class Battlestar. The Libran was put back into service three years before the fall, under the command of Commander Nicholas Theron Tattnall.
