The Kalzerians were near-Humans from the planet Kalzeron with gray, leather-like skin. They also had black teeth, and yellow eyes. Developing from a feudal, tribal people with a defining sense of battlefield honor, the Kalzerians had reached the atomic era by the time of the Galactic Civil War. When Kalzeron was subjugated by the Galactic Empire, some Kalzerians such as the mercenary Azuroth Khell joined off-planet resistance movements. Though Kalzeron was freed from the Empire's yoke following the Battle of Endor, those Kalzerians who had left the planet to fight were branded as cowards by their fellows on their homeworld.
