The Viraanntesse system existed within the confines of the Dona Laza sector, which itself was situated in the Slice region of the larger Expansion Region. This system served as the native world for the sentient Viraanntesse species.
The initial reference to the Viraanntesse system appeared in the 2009 publication titled The Essential Atlas. This reference book, authored by both Jason Fry and Daniel Wallace, identified the system's location as grid square P-9.
