The Biravians comprised an aboriginal population native to the Biravia system. Back in 20 BBY, a Biravian woman voiced her contempt for the Jedi after being halted by a clone trooper at a security control point within Galactic City.
A character of Biravian origin is featured in the Order 66: A Republic Commando Novel, penned by Karen Traviss and released by Del Rey during 2008. The novel does not clarify if Biravian denotes a sapient race or some alternative societal grouping.
