Kiefer was a male lieutenant in the Imperial Army stationed on the planet Bastion. After Emperor Roan Fel was overthrown by the Dark Lord Darth Krayt, a number of Imperials remained loyal to Fel. However, Kiefer—who believed that it was his duty to serve whomever was on the throne, rather than a specific individual—in turn was loyal to Krayt. When Fel arrived on Bastion in 137 ABY, Kiefer commanded him to surrender. However, Fel refused to do so, and much to Kiefer's dismay, none of the stormtroopers accompanying the lieutenant enforced his order. Kiefer responded by drawing his blaster to kill Fel himself, but before he could do so, General Oron Jaeger shot and killed him.
