Jilam Kester was a Human individual of the male persuasion, serving as a member of the Antarian Rangers.
Not long after the Galactic Empire was established, Kester played a role in aiding Jedi in their flight from Emperor Palpatine's hunters via escape routes for refugees. Because of this assistance, he became a target for Squad 40, an Imperial commando unit within the ranks of the 501st Legion. This squad attempted to apprehend Kester on the planet Celen, his place of concealment. However, the commandos were unaware that Jedi Master Iri Camas was present with Kester. Camas made the ultimate sacrificed, diverting the commandos' attention and enabling Kester to get away.
