Jilam Kester, an Antarian Ranger, used Jilam Kester's base as his secret location. This base was situated within the urban landscape of Chelpori, a city found on the planet known as Celen.
Not long after the Galactic Empire came into power, Kester sought sanctuary in his base. From there, he played a role in concealing Jedi from the relentless pursuers dispatched by Emperor Palpatine. These actions by Kester drew attention, leading to Squad 40, a unit of Imperial commando soldiers from the renowned 501st Legion, receiving orders to apprehend him. When Squad 40 launched an assault on Kester's base, they were met with an unexpected figure: Jedi Master Iri Camas. Camas created a diversion, keeping the commandos occupied, which bought Kester the crucial time he needed to flee. Ultimately, Camas made the ultimate sacrifice, triggering a gas explosion that obliterated the base, resulting in his own demise.
