The Nache Bhelfia represented a cyclical hyperlane within the region known as Sith Space. This route served to connect the five hallowed Sith planets: Ziost, Khar Delba, Rhelg, Krayiss II and Korriban, in addition to the smaller planets Nicht Ka and Ch'hodos.
After the Discovery of Korriban occurred in 6900 BBY, the Jedi Exiles Sorzus Syn and Remulus Dreypa charted the course of the Nache Bhelfia hyperlane. Later, Sorzus Syn documented the hyperlane in her personal chronicle, which Darth Sidious subsequently compiled into his work, the Book of Sith.
