Pygorix, a world found in the Pygorix system, existed within the Back Reach region. This region was part of the Gordian Reach sector, itself located in the Trans-Hydian segment of the Outer Rim Territories. The Ardan Cross hyperlane provided a connection to both the Feldwes system and the Spintir system within the Spadja sector. Furthermore, a less significant hyperspace path linked Pygorix with the Karsten's World system.
For centuries, Pygorix functioned as a spiritual sanctuary, renowned for its extended study of the religious doctrines and practices of diverse species. The wealth of Pygorix stemmed from the tariffs levied at an orbital station that functioned as a customs port. Access to the neighboring Karsten's World system was solely granted to the high abbots of Pygorix.
The reference book The Essential Atlas, written by Daniel Wallace and Jason Fry in 2009, was the first time Pygorix was introduced, positioning it within grid coordinate Q-6.
