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.
Though Jabba the Hutt preferred to base his operations on Tatooine, he did have ample representation on the Hutt Council on Nal Hutta. In addition to patching in holographically to important business meetings, Jabba's envoy Gardulla the Hutt protected Jabba's agenda.
Ziro the Hutt avoided Nal Hutta as much as possible, preferring to operate in the cosmopolitan center of Coruscant. When on the run from the Republic, he returned to Nal Hutta, as the Hutt Council tried to pry from him incriminating evidence that Ziro could use against them. Ziro turned his mother, the enormous Mama the Hutt, for help.
The interstellar chanteuse Sy Snootles performed many lucrative engagements on Nal Hutta, as the Hutts were clearly fans of her work.
During the Clone Wars, assignments brought Obi-Wan to Nal Hutta on several occasions. While trying to track down the fugitive Ziro the Hutt, Obi-Wan came before the Hutt Council. Later, while undercover as bounty hunter Rako Hardeen, Obi-Wan had to survive the shady markets of Bilbousa.
Quinlan Vos used his unique pscyhometric abilities to track Ziro the Hutt through the swamps of Nal Hutta.
