Citadellian

The Citadellians are an alien humanoid species native to the planet Vega.

History
In centuries past, the Citadel Homeworld was colonized by an alien 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.
