The Ring of Kafrene was a monumental construction which served as both a mining colony and a deep-space trading post. Its structures, made from durasteel and plastoid, were slung between a pair of malformed planetoids in the Kafrene asteroid belt. Areas such as its aft docking bay were covered in lurid, phosphorescent graffiti. Roads led out from the docking bays towards the distant rock warrens of the planetoids, and the outpost itself was a labyrinthine sprawl of shacks, prefabricated housing, and countless maze-like corridors.

Although there was some structure to the buildings around the main throughways, beyond these areas the layout of the Ring changed almost daily; shacks were made of sheet metal, and shelters utilized housing units recycled from foreign colonies. Alien housing complexes and tenements featured ventilation shafts that sent wafts of ammonia into the streets. The Ring acted as a junction between the Corellian Trade Spine—which connected it to the planets Coruscant and Anoat—and the Biox Detour, which connected it to the planets Takodana and Malastare.
