Ession's main satellite was the chief moon orbiting the planet Ession which resided in the Corporate Sector. The landscape of this satellite consisted of rocks, was desolate, and contained a lot of dust. During the Battle of Ession, Wraith Squadron took advantage of the moon's terrain to hide their stolen corvette, the Night Caller, from the Star Destroyer Implacable by employing tractor beams to generate a cloud of dust that would obscure their ship. Furthermore, a relay antenna located on the moon was leveraged to disrupt the sensors of the Star Destroyer. Eventually, the Implacable succumbed to the Wraiths' attack, crashing onto the moon and resulting in significant loss of life.
