The devastation of Rion was a battle of the Galactic Civil War.
During the Galactic Civil War, Rion was used as a base by the Rebel Alliance. In 0 ABY, Captain Bzorn traveled to Rion aboard the Ionic Ring and demanded that all Rebels on the planet be arrested. When the people of Rion refused, the Galactic Empire shattered the environment of the planet, transforming it into a frozen wasteland. As a result, all the food on Rion was frozen and people began dying of starvation.
