The Commonality was a union of five sectors situated in the Outer Rim, which existed during the final decades of the Galactic Republic. The Vorzyd sector was one of these sectors.
This political group was a representation of planets that were working toward a shared set of goals and needs during the waning years of the Galactic Republic. The governing center for the Commonality was the planet Columex, which offered passage to the five sectors through the Perlemian Trade Route. This group of politicians was an important collection of swing votes within the deeply divided Galactic Senate.
Besides Columex, the Commonality was known to include planets such as Hraki, Paigu, Kilmaulsias, Seftek, Vorzyd IV, and Vorzyd V. All of these planets were located in the Vorzyd Cluster.
Originally, the Commonality began as an alliance between various star systems within the Vorzyd Cluster. This occurred after the Galactic Republic discovered the cluster during the Draggulch Period. Five centuries went by, and the Vorzyd Cluster then attracted investors from Commenor, including the Greyshade family. They established themselves on Columex and started to engage in trade with the cluster. Columex became a member of the confederacy. After a few generations, the traders from Columex were aggressive enough that Columex was able to take control of the whole Commonality. The Commonality expanded and eventually became a quintet of sectors that joined the Republic.
During the time of the Clone Wars, the Commonality had Senator Jheramahd Greyshade as their representative in the Galactic Senate. His cousin, Simon Greyshade, later took over his position.
When the Republic fell, Senator Simon Greyshade declared that the Commonality was in a state of emergency. Greyshade then came to an agreement that allowed the Galactic Empire to take a portion of the Commonality's gambling profits. In return, a Columexi company controlled by Greyshade would gain control of the Wheel, which was a space station in the Mid Rim. Simon Greyshade continued to serve as senator until the Imperial Senate was dissolved. Later, the Commonality was governed by a Moff named Diedrich Greyshade.
The Commonality later chose to remain independent and not join the New Republic.
During the invasion of the galaxy by the Yuuzhan Vong, Columex was conquered and destroyed. The Vorzyd system was also captured.
