Mission to Sibensko

In 28 ABY, the Mission to Sibensko was undertaken by the New Republic Senator Leia Organa and her senatorial staff embarked to the Expansion Region planet of Sibensko. Posing as smugglers, Leia's team managed to infiltrate the underwater Sibensko city. While Greer Sonnel and Joph Seastriker loaded a shipment of thermal detonators, Leia and C-3PO managed to download banking records linking the Amaxine warriors to Rinnrivin Di's cartel. After sending C-3PO back to Greer and Joph's junker, Leia decided to spy on the Amaxine base.

Shortly later, Leia was cornered by Rinnrivin Di himself but managed to kill him and his henchmen by collapsing a hydraulic tunnel on them. She infiltrate the Amaxine base only to be pursued by several Amaxines. Leia fled up a landing platform where she was rescued by her husband Han Solo, who had arrived in a modified racer. Together, the couple shot down two Amaxine starfighters. One of these crashed into the ammunition depot, destroying the underwater city and the Amaxine base. This skirmish effectively eliminated Rinnrivin Di's cartel and the Amaxine warriors as reliable First Order proxy agents.
