During the time of the Imperial Era, a religious cult's pontiff on Vincorba located within the Expansion Region was murdered. This pontiff was an ally of the Crimson Dawn criminal organization, and the act was carried out by three members of the Assassins Guild. These assassins, known as Gee-Ninety, Loriach, and Chilla Zin, had been contracted by Ochi of Bestoon, the Sith assassin who served the Sith Lord Darth Vader. Vader's goal in commissioning the assassination was to evaluate the capabilities of the three assassins to determine if they were fit to aid him in his conflict with Crimson Dawn. After the pontiff's death at the hands of the assassins, Vader and Ochi intercepted their getaway using a landspeeder, subsequently enlisting them into their service.
