A conflict occurred on Telos IV, and it was a component of the Kwymar Suppressions that took place in 17 BBY. The Galactic Empire achieved victory over the Rebel forces situated on Telos IV.
In the early stages of the Imperial Period, the Imperial forces initiated attacks on Rebel bases located within the Kwymar sector. This military operation was known as the Kwymar Suppressions. Telos IV was among the planets subjected to these attacks, ultimately resulting in a win for the Imperial forces.
Sergeant Major Beilert Valance, a Stormtrooper, sustained severe injuries during the campaign on Doniphon, a planet in close proximity, during the Suppressions. Subsequently, his life was preserved at the Anglebay Station medical facility situated on Telos.
