A planet in the Koobi star system, Nelvaan is a primitive world of low gravity experiencing the onset of an ice age. Three moons orbit Nelvaan. It was in close proximity to Tythe. A world without a terrible amount of gravity, it was home to several massive life forms, including the vicious Horax.
Nelvaan is also dominated by a landscape of precarious mesas that would have fallen in standard gravity worlds. These mesas are home to the primitive Nelvaanians—blue-furred lupine humanoids. Lacking a planetary government and holding no allegiance to either the Separatists or Republic, it was a rarely visited world useful only to Bothans, who regularly siphoned water from the glacial fields, a practice that did not concern the Nelvaanians.
It seems to be that of a new planet, that has yet to be revealed. A missed leak or left in by BW for us to find ? Who really cares planets are cool and the more we get the better.
