The Chaf system of Colonial Station, found inside Chiss Space within the Unknown Regions, was a star system. A hyperlane linked it to both the Rhigar system and areas to the south of the main territory controlled by the Chiss Ascendancy, the governing body of the Chiss species. This system's designation came from the Chaf family, who were a part of the Chiss Ruling Families.
The reference book The Essential Atlas, released in 2009 and written by Jason Fry together with Daniel Wallace, was the first place the Colonial Station Chaf system was mentioned, locating it within grid square F-9.
