Devaronians are a horned humanoid species from the world of Devaron in the Expansion Region, a planet of low mountains and deep valleys linked by thousands of rivers. It is believed that they are descended from a race of primates that lived in the mountains of Devaron, and that their horns were a genetic mutation that proved useful in fending off predatory birds.
The Devaronians are one of the most unique races in the galaxy, as their male and female sexes are so vastly different in appearance and temperament. The males are docile, non-aggressive creatures, completely hairless, with red-tinted skin and a pair of large horns growing from their heads. They take great pride in their horns, and groom them quite regularly. Female Devaronians are covered in thick calico fur that ranges in color from brown to white and are hornless. They are aggressive by nature, and tend to dominate their culture. In addition, the teeth of the males are all incisors, but the females also have molars and prominent canines.
Devaronians were one of the first species in the galaxy to develop interstellar travel, and the males of the species have been common sights in spaceports throughout the galaxy for thousands of years. Devaronian males are driven by an urge to wander, usually taking the first opportunity to move on from one place to another. As such, they are often found traveling the galaxy as tramp freighter captains and scouts. Female Devaronians, on the other hand, are content to remain in a single location, and, as such, raise the young and run the government of Devaron. The males send as much money as they can manage back to their homeworld to support their families, but otherwise hardly ever return once they have begun to travel the stars. The females are content with this arrangement, as they tend to view the restless males as disruptive to home life.
