Although both Chiss and Humans speculated about distinct physiological differences, for instance in the vocal apparatus or skeletal structure, there is no really firm proof of stark evolutionary differences. Outwardly, the Chiss were distinguished from baseline Humans by three clearly visible traits-blue skin, midnight-black hair, and glowing red eyes but their blood was red, and a case can be made that all these superficial features were the result of external factors in the biosphere of the ice-locked planet Csilla, said to be their homeworld, or at least, the political, cultural and military center of their civilization.īeyond these potentially superficial differences, it is not clear how far the Chiss diverged from human norms.

The Chiss and baseline Humans regarded each other as aliens, but genetic studies have indicated that the two peoples were close biological cousins, and it is not clear whether the differences between them were the product of straightforward evolutionary divergence and differing planetary habitats, or the result of genetic engineering similar to that which produced such hybrid species as the Massassi, and the Myke. Within Chiss society, children matured very quickly, never truly having an adolescent period before becoming adults. They prefer to extend themselves only from a defensive posture, and viewed the idea of a pre-emptive strike against an enemy as if it were murder. While their history has been marked by nearly continual warfare and conquest of other worlds, the Chiss are generally not violent.

They are all well-muscled and tall, with jet black hair and glowing red eyes. Their homeworld was locked in a planet-wide ice age many millennia ago, and they were forced to flee the planet as a species in order to survive. This race of blue-skinned humanoids was from the planet Csilla, in the Unknown Regions.
