The Citadelians established a tyrannical regime based in a fortress moon known as the Citadel. The citadel then set about to conquer the younger races of Vega. Originally there were only two races in the Vegan system, the primitive Branx and the pacifistic Okaarans, but the Psions used Okaaran DNA to create the other twenty-three races of Vega such as the Tamaraneans, Euphorixians, Aelloans, Karnans, and the Changralyns.
