The Sennex or Sennex Pirates were slave traders from the Sennex system. They were among the most despicable pirates in the galaxy during the time of the Galactic Civil War. Aurra Sing was once in their possession before she took up the bounty hunting business. The pirates told her the Dark Woman had purposely abandoned her before they sold her to Wallanooga the Hutt. Bothered by their presence on Tatooine, Jabba the Hutt sent some of his henchmen to harass the Sennex and remind them who was the true ruler of the planet.
