The Kiliea system, a star system, existed inside the Atrisian Commonwealth. This Commonwealth was situated within the Core Worlds region, specifically in the area known as the Southern Core. Notably, it served as the place of origin for the famed Kiliean bolt guns.
First documented in The Essential Atlas, a 2009 reference work by Jason Fry and Daniel Wallace, the Kiliea system was identified and assigned to grid square J-12 within the book.
