Byss was a mythic paradise world enshrouded in the dark side of the Force, located within the isolated and nearly inaccessible Deep Galactic Core. It was situated at the end of the Byss Run, a heavily guarded artificial hyperlane kept open by hundreds of non-mass S-thread boosters, connecting the planet to the Core Worlds. The planet was otherwise nearly impossible to reach safely through hyperspace, due to the high density of stars in the Deep Core and the constantly shifting patterns of the region’s natural hyperlanes. Byss was the fifth planet of the Beshqek system and orbited the star Beshqek; it was one of two habitable planets in the system, the other being Relus. The planet was orbited by five small moons, which had little influence on its tides.
