The Valiant, a starship utilized by the Galactic Republic, existed during the time of the First Jedi Purge. Opelle held the rank of captain aboard the vessel in the year 3951 BBY.
The Valiant, along with its commanding officer, was originally intended to be a component of a narrative thread within the video game Star Wars: Knights of the Old Republic II: The Sith Lords. This subplot involved the aggressive acquisition of Citadel Station by the Czerka Corporation, but was ultimately removed from the final release. Despite this, a droid stationed at the Telos Security Force headquarters mentions Admiral Carth Onasi's vessel as the Valiant during dialogue (a discrepancy considering the subtitles and the remainder of the game identify it as the Sojourn).
