Nixor I is a world locked in stasis. One side of the planet perpetually faces the sun, while the other is locked in darkness, buried under glaciers kilometers deep. Primitive paintings discovered in caves on the day side show that this was not always the case, telling of a time many millenia past when there was a day-night cycle. Scientists postulate that Nixor I originally had a planetary rotation opposite from how the solar system is spinning as a whole, and it is in the phase of its rotation where it is not rotating. In the next few millenia, it will likely start slowly rotating in the same direction as the solar system. Only time will tell.

The daylight side of Nixor I is dominated by a vast inland sea in the northern hemisphere. This sea affects almost the entire ecology of the northern half of the daylight side. Close to the equator, its azure waters are home to teeming schools of fish and the aquatic predators that feed on them. Further north and west, the waters run underground, giving life to vast jungles of Toa and Aga trees, whose roots can reach hundreds of meters through the rocky soil to reach the water below. To the south of the equator away from standing water, the landscape transforms into vast deserts of sandy dunes and parched rock. Forests of giant cacti have evolved, fed by the moisture coming off the glaciers. These cactus forests are home to large populations of reptiles and insects that have adapted to the constant daylight and have become skilled burrowers in order to find refuge from the sun.

Historically, Nixor I was home to a species of primitive sentients. Little is known about them, save they were never very numerous and decorated their cave dwellings with paints made from the colored earth of their surroundings. These primitive beings were wiped out around the time of the Great Sith War by the Krath, who invaded the Nixor system, making it a stepping stone for further conquest. Likely due to its more agreeable geography and climate, Krath ruins are more common here than on nearby Nixor although by no means common. The largest of these ruins is located on an island in what is now a temperate swamp on the southwestern side of the inland sea. The slowly sinking pyramid is now home to myriad forms of wildlife, but displays a great wealth of carvings and sculpture linked to the heyday of Krath rule.

Needless to say, economic activities are concentrated in the daylight side. An industry almost unique to Nixor I involves the weaving of fine textiles and scarves from the fibers of the desert cacti, which produce fibres of surprising softness and resilience. There are, however, some hardy souls who make a living on the dark side of the planet. Small settlements that harvest the ice for offworld sale to Nixor, and mining towns using deep core drilling technology to reach buried deposits cling to a sparse existence in the darkness, fortified to resist the predatory creatures hunting the everlasting night.
