All Horansi have excellent vision in low-light conditions, but only the Mashi Horansi are nocturnal. Horansi have an atypical activity cycle, with alternating peroids of rest and activity, normally four to six hours long.

Horansi sub-species can cross breed, but these occurrences are rare, primarily due to cultural differences. The Gorvan Horansi are an exception, and have been known to forcibly take wives from other Horansi.

Despite the industrial development being carried out on Mutanda by such corporations as BlasTech and Czerka, most Horansi communities find it more satisfying to retain a primitive and war-like lifestyle. They don't want to unite their people; instead they are manipulated by petty criminals, local corporations, poachers, and powerful tribal leaders. Offworlders occasionally come to Mutanda to hunt the Horansi for their gorgeous pelts.

Through strength of numbers and a war-like nature, the golden-maned Gorvan Horansi are the defacto rulers of Mutanda. They actively encourage hunting and they have no qualms about hunting other Horansi races. Gorvan Horansi are polygamous: a tribe is composed of one adult male, all of his wives, and all of the children. As a Gorvan's male children reach maturity, there is a battle to see who will lead the tribe. The loser, if he is not killed in the battle, is free to leave and establish a new tribe. Many Gorvans in recent years have found employment at the spaceport on Justa.

The Gorvan Horansi have purchased many more weapons than the Kasa, but have shown no interest in the other benefits of technology. Through sheer numbers, they are able to control the other Horansi races, but they don't have a complete control over the situation. Imperial representatives have only recognized and accorded rights to the Gorvan, or specific individuals from other groups if they are "sponsered" by a Gorvan.

Gorvan Horansi are war-like, belligerent, deceitful, and openly aggressive to almost anyone. They dominate the plains of Mutanda and have been able to control the planet and the interactions of offworlders with the other Horansi races.
