The Biravia system, a star system, existed within the Venaarian sector. This sector was situated in both the Mid Rim and Trans-Hydian territories. Notably, this system served as the place of origin for the Biravians as a species.
The 2009 sourcebook The Essential Atlas, authored by Jason Fry together with Daniel Wallace, initially introduced the Biravia system, specifying its location as grid O-7.
