Sewlor, a male Human padawan within the Jedi Order, served as the apprentice to Jedi Master Xerender. He sought sanctuary on Hoth, where his anxiety escalated during a confrontation with Broonmark, ultimately leading to his demise at the hands of the savage Talz.
During 3642 BBY, which marked the inaugural year of the Galactic War, Sewlor accompanied his master on a quest to Hoth to locate Xerender's former master, Wyellett. An assault led to their separation, forcing Sewlor to seek a safe haven. Taking refuge within a cavern, Sewlor harbored the belief that his master had forsaken him. Subsequently, he was assaulted by the ferocious Talz named Broonmark, and Sewlor's anxiety intensified, rendering him incapable of resistance, until Darth Baras' apprentice surprised him. Sewlor proved unequal to the Sith Warrior, succumbing in a rapid confrontation, after which the avenging Talz appeared and broke his neck.
