Zavval, the Hutt who oversaw the spice processing facility on Ylesia, was the sibling of Aruk Besadii Aora and the brother of Borga Besadii Diori. Reporting to Aruk was Zavval, who received reports directly from Teroenza. Zavval met his demise when a ceiling caved in as Han Solo and Bria Tharen made their escape from Ylesia. Angered by Zavval's passing, Aruk swiftly appointed his nephew, Kibbick, as his replacement, only to discover Kibbick was utterly incompetent.
