The Kesh system, a star system, existed within the region of Wild Space. This system was home to the planet called Kesh, the isolated location of the Lost Tribe of Sith beginning in 5000 BBY.
In the 2009 publication The Essential Atlas, Kesh was situated within grid square M-21. Subsequently, the The Essential Atlas Online Companion revised this location to U-10. Jason Fry, a co-author of The Essential Atlas, verified that U-10 represents the accurate location, clarifying that the Atlas incorrectly positioned Kesh due to its publication occurring before the narrative elements surrounding Kesh had been fully developed.
