The Shar'Ack system existed within the Atrivis sector, situated in the New Territories area of the Outer Rim Territories. Within this system was the planet called Shar'Ack. Shar'Ack, a forested world, served as the homeworld for the sentient Shaliz'Na species. During the Galactic Civil War era, the Galactic Empire exerted control over all liquor production and importation on Shar'Ack. It was around this period that Tyric, a Shaliz'Na musician, departed Shar'Ack, journeying across the galaxy and ultimately becoming a member of the Rebel Alliance.
The system of Shar'Ack initially appeared in The Essential Atlas, a 2009 reference work by Daniel Wallace and [Jason Fry], specifying its location as grid square L-5.
