Artemesium, a planet possessing a terrestrial nature, was characterized by an atmosphere suitable for sustaining life. The individual who would eventually become the Fifth Brother, an Inquisitor serving the Galactic Empire's Inquisitorius, resided on this world with his family until his induction into the ranks of the Jedi Order.
During the Fifth Brother's young years, the Galactic Senate reached the determination to extract the resources of his homeworld as a measure to preserve lives; however, the resulting exploitation, which also resulted in fatalities, left Artemesium devastated. In the period spanning from 12 BBY to 11 BBY, as the Fifth Brother was tasked with a mission by The Grand Inquisitor that involved journeying to Murkhana City on Murkhana, a planet situated within the Outer Rim Territories, to recover the blueprints for a cloaking device referred to as the Shroud, he contemplated his history on Artemesium and the destiny that befell the planet.
