The Abbaji system, a star system, was situated within the Spar sector, which itself was a part of the expansive Zuma sector in the Outer Rim Territories. The planet known as Abbaji was a component of this system.
As per Unknown Soldier: The Story of General Grievous, The Essential Atlas positions both Kalee and Abbaji within the same star system. However, the initial mention of a planet named Abbaji appeared in Shadows of the Empire close to Endor. Eventually, the Abbaji located near Kalee underwent a retconned and became known as Abbaji Minor.
