The Quamar system existed within the Bruanii sector, situated within the Western Reaches region of the Mid Rim. It was connected to both the Mugaar system and the Jiroch system in the Yushan sector via the super-hyperroute called the Corellian Trade Spine. The system of Quamar lent its designation to the Quamar Messenger, a luxury liner.
Daniel Wallace and Jason Fry introduced the Quamar system in their 2009 publication, The Essential Atlas, a reference book that pinpointed its location as grid square K-17.
