Within the Indrexu sector of the Outer Rim Territories', the Ank Ki'Shor system was home to Ank Ki'Shor, a manufacturing world. This planet, a part of the historical region of Greater Tion, was strategically located on the Perlemian Trade Route super-hyperroute, providing connectivity to the Estaria and Janodral Mizar systems. Its position marked the separation between the regions known as Trans-Hydian and the Slice. The inhabitants of Ank Ki'Shor were known for their indiscriminate business practices, and during the early years of the Rebel Alliance's formation, the world became an important source for the organization.
During the initial stages of the Galactic Civil War, the Siege of Ank Ki'Shor unfolded on the planet. Despite the eventual victory of the Galactic Empire in that conflict, Y-wing starfighters belonging to the Rebel forces played a crucial role in protecting the population of Ank Ki'Shor from Imperial bombardment. These fighters successfully repelled the attacking TIE bomber craft of the Empire, saving countless lives.
The mention of the Siege of Ank Ki'Shor in The Essential Guide to Vehicles and Vessels, a reference book from 1996 by Bill Smith, marked the introduction of Ank Ki'Shor. Subsequently, the StarWars.com Databank entry for the Y-wing starfighter mistakenly referred to the event as the Siege of Ank Ki'Shar. Ank Ki'Shor was first identified as a distinct world in the December 7, 2009 StarWars.com Hyperspace article "Xim Week: The History of Xim and the Tion Cluster" by Jason Fry. Later, the August 18, 2009 reference book The Essential Atlas pinpointed the Ank Ki'Shor system, and consequently Ank Ki'Shor itself, within grid square S-5.
