The Citadellians (also spelled Citadelian) were an alien humanoid species native to the planet Vega, known for their military skills, and power lust.
In centuries past, the Citadel Homeworld was colonized by an Okaaran-Branx hybrid known as the First Citadellian. He cloned himself, and thus, the Citadellian race was born.
All Citadellians are clones, therefore, there are only males, no females.
The Citadellians eventually established an interplanetary empire known as the Citadel, which governs twenty-one of the twenty-two planets in the solar system.
