Vainglorious was an Imperial warship that was present at the Battle of ThonBoka. Its captain questioned Rokur Gepta's tactics before the main battle. The Sorcerer of Tund subsequently ordered that both the captain and his executive officer should be thrown out of an airlock for being individualists.
This was one of the Imperial cruisers that participated in the blockade of the ThonBoka, during the early years of the New Order. Rokur Gepta stripped the ship's captain and his second-in-command of their rank after the captain of the Intractable refused to be a front-line attacker. Gepta then ordered them all forced out of the airlocks on their vessels, as examples of what would happen to any other officers who dared to disobey his orders.
