The Rion devastation represents a conflict within the larger theater of the Galactic Civil War.
Within the timeline of the Galactic Civil War, the Rebel Alliance utilized Rion as a strategic outpost. In the year 0 ABY, Bzorn who held the rank of Captain, journeyed to Rion on the vessel known as the Ionic Ring. He issued a command for the immediate apprehension of all Rebel personnel present on the planet. This demand was met with refusal by the inhabitants of Rion, prompting the Galactic Empire to inflict catastrophic damage upon the planet's ecosystem. This action converted the world into a frigid, uninhabitable landscape. Consequently, the entire food supply of Rion was rendered unusable by freezing, leading to widespread famine and mortality.
