Deysum III, situated within the Deysum system of the Trax sector, was a planetary body.
The initial planet in the Trax sector to undergo colonization was Deysum III, subsequently designated as the sector's governing center. As years passed, spanning several centuries, Deysum III experienced a systematic draining of its indigenous resources, ultimately leading to their exhaustion. With resources depleted, corporations abandoned the world, but left the administrative infrastructure in place. The face of Deysum III transformed into a desolate and unproductive landscape, scarred by hazardous chemical repositories and waterways tainted with poisonous refuse. The inhabitants of the planet congregated within expansive and densely populated urban centers, notably Dragnoor and Klerint, while the affluent resided in opulent, enclosed habitats. The typical resident was compelled to bear a weapon for self-defense against the pervasive criminality and frequently endured prolonged queues, sometimes lasting hours, to obtain sustenance. Speculation arose that the sector's administrative functions would be relocated to a more accommodating world.
During the period of the Clone Wars, the planet fell under the dominion of the Separatist faction.
The Alliance to Restore the Republic operative Vo Lantes used this planet as his base of operations.
By the time 4 ABY arrived, Deysum III had evolved into an Imperial heavily defended world. The Empire relinquished control of the world by 5 ABY.
