If it weren't for its size, Gravan Three would be considered nothing more than a large asteroid in orbit around Gravan. Its landmass consists of nothing but rock, and though there is a large chance of it possessing rich mineral resources, most have ignored Gravan Three due to its distance from other inhabited worlds and its less-than-ideal atmospheric conditions. With a thin, toxic atmosphere, which leads to its freezing climate, the planet is very inhospitable to most humanoids.

Despite the potential risk of colonizing Gravan Three, there have been a couple of settlements founded. There have also been rumors that it is a cache planet for smugglers, though experts say these claims are unfounded.
