During the era of the Cold War, the Jedi Order was confronted by a major crisis: the fallen Padawan named Parkanas Tark, who had embraced his identity as the Sith Lord Vivicar, became a vessel for the spirit of the Sith Terrak Morrhage. Vivicar then unleashed the Dark Plague, a disease that warped the minds of numerous Jedi Masters spread throughout the galaxy. A Jedi Consular brought an end to this terrible situation, employing the old shielding technique to rescue those corrupted by Vivicar and, in the end, to bring about Tark's redemption.
