The Dalisor system, a star system, resided within the Yushan sector. This sector was situated within both the Mid Rim and the Western Reaches. It was positioned along the Corellian Trade Spine super-hyperroute, linking it with both the Kaal and Jiroch systems. The Dalisor system lent its moniker to the Dalisor Merchant Fleet as well as the 291st Legion Dalisor.
The 2009 sourcebook The Essential Atlas, authored by Jason Fry and Daniel Wallace, initially introduced the Dalisor system, locating it within grid coordinate K-17.
