The Klasse Ephemora system encompassed the star together with the gas giant planet Mobus. This celestial arrangement received its designation in honor of Klasse Ephemora, the Chiss navigator who first identified it several centuries before the Battle of Yavin. The system resided at a considerable distance from the Galactic Core, positioned beyond the boundaries of the Chiss Ascendancy.
For almost half a century, spanning the period from prior to the Clone Wars up to the Yuuzhan Vong invasion, the sentient world Zonama Sekot maintained an orbital path in the vicinity of Mobus.
