Original Game Codex TextIn response to the Emperor’s return, the Republic Strategic Information Service has begun to assemble a joint task force with the sole purpose of finding the ancient Sith ruler and destroying him at last. Initially proposed by SIS agent Theron Shan, the organization will eventually include representatives from the Jedi Order, Republic Special Forces, “paid consultants” from the underworld–anyone who can contribute to the Emperor’s downfall. As with anything in the Republic, it’s possible that politics may play a part in the group’s final assembly and resources. But given that its founding members witnessed the return of the Emperor firsthand, it’s unlikely that anything will be allowed to impede the task force’s progress for long.
