Located in the J Star Cluster, the Quad Planetary System ("the Quad") takes its name from the four inhabited bodies that comprise it: the dwarf planet Qresh and its three moons, Arkyn, Westerley, and Leith. These four worlds represent a politically, economically, and legally entwined planetary unit. Qresh orbits a G-main sequence star in the J Cluster.
Within the Quad, the Company has laws regarding cybernetic implants. Performing biotech modifications beyond certain limits is illegal, and anyone who's more than 26% modified is banned from the Quad and isn't considered a person under Company law.
