The Kyrska system resided in the Hevvrol sector, which itself was situated within the Trailing Sectors area of the Mid Rim. It bore the same designation as the Siege of Kyrska, a brutal, three month duration urban battle fought during the era of the Galactic Civil War.
This system, Kyrska, first appeared in the 2009 publication The Essential Atlas. This reference book, penned by Daniel Wallace and Jason Fry, specified its location as grid square P-15.
