Commander Keten served as a commander under Imperial Remnant Moff Kurlen Flennic throughout the Yuuzhan Vong War. Known for his formal demeanor and a low, rumbling voice, he was an authoritative figure.
Following the escape of the Jedi team on the Jade Shadow from the Battle of Bastion, they made their way to Yaga Minor. A patrol of TIE Fighter craft quickly detected them, leading to an encounter with Keten. He demanded to know their purpose and gave the order for the Skywalkers to prepare for boarding.
While the Skywalkers discussed their options, Keten drew near in an armored Imperial transport, escorted by twelve TIE Fighters. He soon insisted on an answer. Mara Jade Skywalker, cautious about the situation, chose to invite Keten onto their ship, believing a mind trick could de-escalate the tension. However, Keten, aware of Jedi mind tricks, informed Jade Skywalker that only Mark Five security droids would comprise the boarding party.
Before his vessel could connect with the Jade Shadow, Captain Arien Yage of the Widowmaker commanded Keten to halt his actions. Keten, subordinate to Captain Yage, conceded to her command, but insisted that his objection be formally noted.
