The Quesaya system existed within the Andirma sector of the Expansion Region. Its designation was the same as the Quesaya Border Conflict, a historical event that took place in 4007 BBY. As of 3996 BBY, this system was positioned within the "civilized galaxy," a part of space extensively explored by the forces of the Galactic Republic.
The initial reference to the Quesaya system appeared in The Essential Atlas, a reference book from 2009 penned by Daniel Wallace together with Jason Fry; the system was located in grid L-15 within the atlas.
