The Cavrilhu Pirates were a band of pirates who made their base of operations in the Outer Rim.
These pirates were commanded by Captain [Zothip], who operated from the vessel known as the Void Cutter. They ran their operations from various secret locations, including their installation situated within the Kauron asteroid belt.
During the period of the Thrawn campaign, Niles Ferrier successfully stole three IPV-1 System Patrol Craft from them while in the Amorris system. His intention was to sell these ships to the Empire.
Leading up to 19 ABY, Zothip initiated a deal to supply Preybird-class starfighters to the Imperial Remnant. This arrangement was made with Lord Graemon and Moff Vilim Disra. However, the agreement fell apart when forces loyal to Fleet Admiral Gilad Pellaeon discovered that the starfighters were being acquired from pirates instead of the SoroSuub Corporation.
After Disra terminated their arrangement, Zothip, along with several others, went to Bastion to confront Disra. Shortly before the signing of the Pellaeon–Gavrisom Treaty, Zothip was killed. One of his lieutenants, a pirate known as Control, orchestrated a confrontation between Zothip and Disra. Karoly D'ulin of the Mistryl Shadow Guard killed Zothip, and Control subsequently assumed leadership of the Cavrilhu Pirates. In 19 ABY, Luke Skywalker managed to infiltrate their base located in the Kauron asteroid belt. He was captured but survived only due to the timely intervention of Mara Jade.
Following the escape of Luke Skywalker and Mara Jade from the pirate base, the Cavrilhu Pirates initiated a search for the two Jedi. They eventually located their trail in the Nirauan system. Upon arriving at Nirauan, the Jedi were no longer present; however, the pirates discovered the Hand of Thrawn. The base's defenses had been destroyed by the Jedi, which forced the personnel to evacuate, and the pirates seized control of the base.
