The Kessel sector included the Kessel system.
Behind the scenesEdit
The Kessel system was first mentioned in The Hutt Gambit, written by A. C. Crispin (1997). Shortly after this publication, the computer game Star Wars: Rebellion (1998) placed Kessel in the Calaron sector. Rebellion made a number of arbitrary placements of planets for game-play purposes; consequently, Leland Chee, Keeper of the Holocron, has stated that when its placements conflict with existing canon placements, they are overridden. It's placement of Kessel is one such example to which this ruling applies.
