The Pa'hir'al system existed within the Urce Space region. This region was situated within the Lesser Plooriod Cluster, itself a component of the New Territories area of the Mid Rim. The settlement of Pa'hir'al City was located within this system. It was here that Tirranna, a Wookiee agent working for the Rebel Alliance, was taken into custody by the forces of the Galactic Empire circa 1 BBY.
The reference book The Essential Atlas, published in 2009 and authored by Daniel Wallace together with Jason Fry, provided the initial mention of the Pa'hir'al system, locating it within grid square L-7.
