Lurkan was a Klingon male serving in the Klingon Defense Force in the 2370s. By 2375, he was the captain of the IKS Ning'tao. During a raid on Trelka V, his ship left formation, so General Martok had him reminded about the importance of keeping formation. Later, he was deemed too young and inexperienced to engage a group of Jem'Hadar attack ships in a delaying action, so he was supposed to transfer command to Worf, though Kor took Worf's place. (DS9: "Once More Unto the Breach") This character was only mentioned in dialogue.
