Selross, a Hutt possessing a masculine demeanor, ascended to the position of head of the Vosadii kajidic throughout the Clone Wars. As leader, Selross guided the Vosadii into criminal enterprises centered around technology, implicating the group in acts of spying and observation. As the Galactic Civil War progressed, Selross, increasingly suspicious of the Galactic Empire and fellow Hutts within his organization, seldom ventured beyond the confines of the Vosadii Techno-Palace situated on Sleheyron.
