Cassander served as the primary planetary body of the Cassandran sectors. Functioning as the sector capital for the Cassander sector during the reign of the New Order, it also lay along the well-known trade route, the Braxant Run.
In the era of the Galactic Republic's expansion into the New Territories, this world attempted to compete with Ord Mantell in trade, but was ultimately unsuccessful.
Prior to the Galactic Empire's control, this planet rose to prominence as the core world of the Cassandran Worlds. Subsequently, in the early phases of the Yuuzhan Vong War, it fell under the control of the invading Yuuzhan Vong.
