The Honorable Union of Desevro and Tion represented a political union situated within the bounds of the Tion Cluster. Desevro, a planet, served as its designated capital. This entity was among the warring factions that emerged from the collapse of Xim the Despot's empire in the hundred years subsequent to his death.
The year 23,900 BBY marked the dissolution of the union, a consequence of the conclusion of the Tionese War. This conflict pitted the union against both the Galactic Republic and the Hutt Empire. Subsequent to its defeat, the territories previously under the union's control were integrated into the Republic as a constituent sector.
