Kebron's career started at the age of 15, when he lied about his age to join the Starfighter Corps. By the age of 18, he had been promoted to Sergeant and was given permission to attend the Imperial Academy.
He graduated from Imperial Academy at Carida at the age of 22 with the rank of Flight Lieutenant, and was assigned to 181st Fighter Wing as Iota Squadron Executive Officer. Kebron showed great skill as a pilot and was made Commanding Officer of the squadron. He was promoted to Captain and transferred to Naval Operations. Kebron was given command of ISD II Legendary and sent to map the Unknown Regions. During this time, the Empire crumbled and the Warlords took power.
By the time Captain Kebron had returned, the Empire had been reformed as the Imperial Remnant. He served with distinction in major conflicts and was promoted to Commodore.
After the attack on Alderaan, Kebron was promoted to Admiral and was given command of the 1st Fleet, with his flagship as the Executor-class Star Destroyer Quicksilver - very apt, considering that his Academy nickname was 'Quicksilver'.
