Before getting hired by Ryn, Zior fought for the Rebel Alliance. He was a very gifted fighter pilot and was also very arrogant. After the galactic civil war came to an end Zior saw little reason to join the New Republic as a fighter pilot. He wanted to act more freely and didn't want to go where the fleet admirals told him to go. Seeing that beeing a pilot for Ryn was a good way to continue to help maintain galactic peace while keeping himself relatively independent he signed on with Ryn and his crew.
Despite his motives for joining the crew Zior respects Ryn as the captain and tries to follow his orders to the best of his abilities. Zior's current wardrobe consists of a dark blue skin tight flight suit that shows off his sleek muscular frame with a combat harness strapped over it. He also has a DL-22 blaster pistol in a hip holster he always keeps with him.
