Jabba the Hutt was one of the galaxy’s most powerful gangsters, with far-reaching influence in both politics and the criminal underworld. There were no second chances with Jabba, something Han Solo would find out -- though the slug-like alien would ultimately fall victim to his own hubris and vengeful ways.
Jabba the Hutt's Uncle Ziro conspired with Count Dooku to kidnap Jabba's son Rotta, reasoning that when the Jedi sent to retrieve Rotta died, the Republic would be forced to apprehend Jabba, leading to Ziro gaining control of their clan. When the conspiracy unraveled, Ziro was imprisoned on Coruscant. Cad Bane freed him and turned him over to the Hutt Council, who feared that Ziro might tell the Republic of their many dirty dealings. Ziro escaped the Hutts, but could not outrun his past.
One of the ruling members of the Hutt Council, Gorga the Hutt kept his sharp eye and pudgy fingers on the flow of credits into Hutt coffers. Knowing full well the scheming nature that the Hutts take deep pride in, Gorga ably accounted for skimming and outright theft while ensuring the criminal enterprise remained healthy enough to thrive. He would regularly meet with his fellow Hutt councilors in the halls of the Grand Hutt Council on Nal Hutta, where his voice was given equal measure, though it was not as weighty as that of the mighty Jabba.
A ringed, marshy bog planet controlled by the Hutts, Nal Hutta has long been a haven for criminal activity, far from the prying eyes of galactic authorities. Its hot atmosphere is frequently streaked by greasy rain, creating a fetid sauna in which Hutts are most comfortable. Hutt cities are built on what little firm land there is, including the sprawling spaceport market of Bilbousa. A number of floating homes also dot the bayous -- visitors traverse the bogs on repulsorlift fanboats, risking the attention of dragonsnakes and other dangerous creatures.
A proud Zygerrian, Darts D'Nar longed for the days when Zygerria was once again an influential power in the galaxy. He believed that an alliance with Count Dooku and the Separatists was a step in the path towards rebuilding this former glory, though he was often impatient at the Count's indirect means. To D'Nar, power not flexed is power wasted. With relish, he supervised the conquest of Kiro, and the forced relocation of thousands of Togruta colonists. A powerfully built Zygerrian, Darts D'Nar was a master of the electro-whip.
Heir apparent to the Hutt empire, Jabba's infant son was barely old enough to slither before his conniving and power-hungry great-uncle, Ziro, already had him marked for death at the time of the Clone Wars. Ziro arranged for Rotta to be Huttnapped as part of an elaborate scheme to discredit the Jedi Knights and prevent them from entering an alliance with the Hutts.
