The Essential Atlas places Kalee and Abbaji in the same system according to Unknown Soldier: The Story of General Grievous but a planet called Abbaji was first mentioned in Shadows of the Empire near Endor. The planet Abbaji near Kalee was eventually retconned as Abbaji Minor.
Jason Fry also confirmed that, contrary to the Kalee article in The Essential Atlas, Tovarskl is in a separate system than Kalee, like represented on the Pentastar Alignment map.
