In the decades leading up to his success, Nem'ro was a cunning leader in the gangs of Jiguuna, an industrial town on the Hutt's adopted homeworld of Hutta. He was an ambitious Hutt, using blackmail and savage cunning to systematically muscle his way into complete control over Jiguuna. His current businesses included Shvash Gas mining, dealing spice and trafficking weapons. His path to success had earned him enemies along the way including Fa'athra the Hutt, "Huttsbane" and even Black Sun.
Like most all Hutts who reach the peak of their career, Nem'ro left the day-to-day operation of his enterprises to underlings while he concentrated on food and revelry.
