The Phr'sha system, the birthplace of the Phr'shan maneuver unarmed combat style, resided within the Fei Hu sector. This sector, in turn, was situated in the Slice region of the Mid Rim.
Within the StarWars.com Online Companion for the 2009 reference book The Essential Atlas, authored by Daniel Wallace and Jason Fry, the Phr'sha system was first defined and assigned the grid square P-13.
