Star Wars: In Harm's Way
“It is a vast criminal syndicate…its influence felt on every planet from the Core Worlds to the Outer Rim. Black Sun has existed for hundreds of years, and embedded itself in the very fiber of the galaxy. The resources at its disposal are almost limitless. The soldiers under its command number in the tens of thousands. The ignorant even call it the most powerful force in the known universe.” ―Darth Sidious, to Darth Maul
Black Sun was the most powerful and infamous crime syndicate of its time in the galaxy.
Black Sun held a massive amount of reach and influence, extending its tendrils of corruption deep in the various galactic governments of each era. It was infamous for its involvement in piracy and smuggling. But smuggling was just the tip of the iceberg of the galaxy-wide organization. It was involved in every known type of illegal activity; its information networks surpassed even the accuracy and scope of Imperial Intelligence. The resources available to Black Sun rivaled those belonging to a large planetary army, including foot soldiers.
Below the leader of Black Sun were nine Vigos (Old Tionese for “nephew”). Each Vigo ruled over his or her own territory and sector.
