Ur-Quan

The Ur-Quan evolved on a world far distant from the region of space depicted in the Ur-Quan Masters. Their world was harsh and violent, and they evolved the capacity to dominate that world. They became the top preditors of their world. Their only threats were each other, so they had problems getting along with one another. Eventually, they found a way to cooperate with one another, and they formed the rudiments of a civilized society to the best of their abilities.

With a civilized culture driving them, they set out to explore known space. Their forays bore fruit quickly, as they met a race known as the Taalo. The Taalo, being effectively rocks, did not evoke the Ur-Quan's preditory nature. The Ur-Quan could mingle amongst the Taalo without having to fight their biological instincts to kill and dominate. The Taalo belonged to an organization of species known as the Sentient Milieu. Eventually, the Ur-Quan joined the Sentient Milieu, and became a member race in that venerable organization.

Though they were members of the Sentient Milieu, they still had difficulty intercoursing with other non-Taalo species. As such, they performed the duty to which they were best suited: solitary exploration missions. The Ur-Quan excelled at this task. But, it was in doing so that they brough doom upon not only the Ur-Quan species, but all of the Sentient Milieu as well.

On one expedition to a planet, the Ur-Quan scout discovered the presence of a sentient species known as the Dynarri. This species had the ability to control the minds of vast numbers of sentient beings. The Dynarri rapidly conquered the Sentient Milieu. Only the Taalo were immune to the Dynarri's compulsions. This could not be tolerated, so the Ur-Quan were forced to help exterminate the species they once called friend.

The Dynarri forced the Ur-Quan to destroy a few other members of the Sentient Milieu over the centuries that they served under Dynarri compulsion. The Dynarri visitted other forms of pain upon the Ur-Quan, by tampering with them at a generic level. The Ur-Quan were the easiest for the Dynarri to control, so they wanted to maximize the use of this species. They fractured the Ur-Quan species into two races: the Ur-Quan Kzer-Za, the green Ur-Quan, and the Ur-Quan Kohr-Ah, the black Ur-Quan.
