[Data reconstructed from the SCORPIO databanks and the personal recollections of Megasecurity Ward 23 inhabitants.] The Great Hyperspace War was a turning point for civilization. For the first time, the galaxy itself was imperiled, and every living being put at risk. History nearly ended. And why? Because the Jedi and the Sith–ordinary people with extraordinary might–went too far, and there was nothing anyone could do to stop them. We cannot change the nature of ordinary people. But we can control them. We have assembled the best men and women of our generation, individuals with the power and the will to effect change. Some of you see yourselves as rivals elsewhere, but here we are partners. Our goal is not to conquer or to punish, but to preserve civilization as we know it. We will work in secret, so that no one may fear us. We will conceal the Sith from the Jedi, and the Jedi from the Sith so long as we can, and we will let them command the world that they see. But they will see only what we let them see. [Reconstruction ends here.]
