The region contained a cluster of 192 star systems close to the Perlemian Trade Route. The Ktilac Regions was a confederacy ruled by three species, the Ktilac, Murachaun, and Tocoyans. These species formed a common culture and religion where they saw themselves as complementary to each other and considered the rest of the galaxy unholy. Apostates of their religion were often exiled.
The Ktilac Regions joined the Galactic Republic with the status of Allied Region that allowed it to conserve some independance. The confederacy maintained this status in the New Republic and the Galactic Federation of Free Alliances.
