Last of Our Kind
After humans and mutants began to settle new galaxies, there became unrest. It was clear that humans thought higher of themselves over all other beings known. This became tested more when they met the Ziron and the Taurathi.
The Ziron were the first to meet the humans. The humans were impressed by the technology that the Ziron possessed. Therefore, it just wouldn’t make sense for the humans to just annihilate them without first learning a thing or two. The humans learned what they could, but the annihilation process had started without an effort on the humans behalf. For unknown to both races, diseases from humans were often deadly to the Ziron people. Thus they began falling one by one until their races numbers barely dwindled. Those who survived did so with re-breathers adapted to protect them from their visitors.
