The Phelope system existed within the Gateworlds, which were situated in the Hapes Cluster of the Slice region of the Inner Rim. Hyperlane connections linked it to the Zadaria system in the Gateworlds, as well as the Ediorung system found in the Interior Region. The system of Phelope is where the drink known as A Walk in the Phelopean Forest originated.
The reference book The Essential Atlas, which was released in 2009 and written by Daniel Wallace together with Jason Fry, first presented the Phelope system, locating it within grid O-9.
