|Planet of origin|
The Givin were the indigenous sentient species of Yag'Dhul. They were encased in featureless white exoskeletons that allowed them to survive for a day in vacuum. Their faces were also featureless, except for three large holes which with some imagination could represent two eyes and a mouth. This, along with their uncanny obsession with mathematics, made them appear creepy and evil to most other species, which was pretty much a given for the Givin.
A Givin terrorist group called the Ku Klux Klan operated shortly after the end of the Galactic Civil War.
