- "You just refuse to wake up, don't you? Not your trooper designation. Your name. From before you signed up. I'm Corlac. And you are?"
- ―Corlac to Terex
During the Galactic Civil War, Corlac signed up to serve the Galactic Empire as a Stormtrooper. He took the designation, "TK-605". Corlac, along with fellow trooper TK-603 and their corporal fought the New Republic forces at Jakku. As the battle ended in favor of the New Republic, Corlac then shot the corporal. He and Terrex then took off their armor knowing that the New Republic would hunt down anyone who fought for the Empire.
After burying their armor, they searched for a settlement for work and to lay low to find a way off-world. A year later, Corlac and Terex were able to use a head of a AT-AT and make it into a ship to get them off-world.
