Usk II, the largest and furthest flung planet from the center of the system, has an unusual band of lava striping the planet diagonally from pole to pole. Settled in between the largest two lava lakes is the Twin Forks mountain range. Although most visitors to the planet assume that the mountains are named for the shape that the mountains form when viewed from space, it is also theorized to be an homage to the planet’s earliest settlers. Klatooinian and Nikto pioneers who had escaped a lifetime of servitude under the Hutts formed a mining settlement where they hoped to profit from the sweat of their toil. This settlement, named Saruhurog, was situated at the base of the connecting point between the two prongs on the fork. Even though historians today are uncertain of the etymology of the settlement's name, most believe the word means something close to unity; just as the north and south forks united at the base of the Sarurhurog Mountain (the tallest peak in the Twin Forks), so too did the Klatooinian and Nikto unite to create new lives for themselves.

Because of the toxic atmosphere and cold temperature, Usk II is sparsely populated, especially the further one travels away from the Twin Forks. Nonetheless, as a mining concern in the system, there are pockets of development scattered throughout the vast glacial plains that make up the majority of the planet’s surface. The local government, however, discourages novice explorers from straying too far from cities without an experienced guide who can help navigate the twin dangers of the volcanic atmosphere and chilling climate.
