Early during the Imperial Period, the Rebel bases in the Kwymar sector came under attack by the Imperial forces in a campaign known as the Kwymar Suppressions. Telos IV was one of those planets attacked. The Imperial forces were victorious.
During the Suppressions, Stormtrooper Sergeant Major Beilert Valance was severely injured during the campaign on nearby Doniphon. His life was later saved at the Anglebay Station hospital on Telos.
