Walex Blissex was a doctor and engineer of starship design, and later a general of the Alliance to Restore the Republic, esteemed and respected throughout the galaxy. His designs ranged from mammoth warships to minuscule starfighters, and his clients ranged from pan-galactic governments to insurrectionist rebellion movements. Working for such shipyards as Kuat Systems Engineering and Rendili StarDrive, Blissex created mainstays of the Grand Army of the Republic, such as the Delta-7 Aethersprite-class light interceptor, and the Victory-class Star Destroyer. Blissex himself was not at ease with creating craft that could and would be used as killing machines, but he consoled himself with the fact that they were being used to police the galaxy and keep others from harm. Unable to use a computer properly, Blissex relied on assistants and his daughter, Lira.
 
When Supreme Chancellor Palpatine made his grab for power in 19 BBY, Blissex chose to disappear from the galactic spotlight. He was idealistic, and he vehemently disagreed with Palpatine's policy of using weapons of mass destruction to police his new Galactic Empire, but he understood the threat that the Emperor posed to his safety. Rather than be forced to do that which he believed wrong, Blissex became one of the founding members of the Alliance to Restore the Republic. Despite this, his daughter married Imperial Governor Denn Wessex of the Relgim sector and took her father's intended place in the Empire. She designed the Imperial I-class Star Destroyer, working from her father's designs for the Victory I-class.
