- "Sergeant Defain, 21st Starfighter Division. Flew sorties at the Battle of Coruscant and Ilum, decorated for both."
- "Our girl here's the right size, but she's built for stealth, not grit. Hold on tight."
At the end of the Great Galactic War in 3653 BBY, Defain participated in the battle of Coruscant where he flew sorties in the Twenty-first Starfighter Division. He also participated in the battle of Ilum in 3641 BBY.
Later around 3639 BBY, he was stationed over Makeb where he awaited an Imperial strike team to take down to the planet. However, during the landing, the shuttle crash-landed and the pilot was killed in the crash, leaving the Imperial strike team to handle the mission with the assistance of Katha Niar.
