Darth Jadus was a male Human Dark Lord of the Sith of the resurgent Sith Empire and a member of the Emperor’s Dark Council. Said to be second in power to only the Emperor, Jadus initially concentrated his attention on overseeing the Imperial Intelligence network, controlling it through various liaisons. Concerned about the future of the Empire due to his fellow Lords’ constant civil wars and xenophobia, Jadus eventually began a secret coup against the Dark Council, seeking to unify the Empire and bring the ways of the Sith directly to its citizens.
Jadus was a male Human Dark Lord of the Sith. Presumably born on the Sith capital of Dromund Kaas, located in the Outer Rim, Jadus rose to prominence among the Sith during the years of the Great Galactic War and the subsequent Cold War, securing a position for himself on the Sith’s Dark Council and developing into its most powerful member. The Sith Lord also gained control of the Imperial Intelligence spy network during the Cold War, working behind the scenes through various intermediaries. At some point he sired a daughter who became his only known apprentice. Jadus also commanded the Imperial dreadnaught Dominator.
In 3643 BBY a new terrorist organization emerged in the Empire, the Eagle’s network, which Jadus instructed a new Intelligence recruit to investigate. The terrorists soon launched an attack on the generators powering Kaas City, failing only due to the efforts the agent. A simultaneous attack, however, bombed the Dominator, killing thousands of Imperial dignitaries aboard for a planned cruise across the Empire. Jadus was also on board and thus presumed dead, leading the Dark Council to elect his daughter Darth Zhorrid as his replacement. Zhorrid ordered Intelligence to use all its resources to find the terrorist leader Eagle and provide her with revenge.
Imperial Intelligence, thanks to the agent now codenamed Cipher Nine, began disassembling the Eagle’s entire network. In the end they found and killed the Eagle himself, who was attempting to use experimental Imperial weapons known as Eradicators to launch a devastating attack on Imperial holdings. Before dying, however, the Eagle revealed that he had a mysterious «Patron» high up within the Empire.
Hunting down this Patron, Cipher Nine discovered it to be Darth Jadus; he had been the real leader of the Eagle terrorists all along. By faking his own death, holding the Dominator together through the Force while shvash gas incinerated it, he had weakened the Council as they fought each other to claim his resources. He intended to finish the job with the Eradicators, using them against the Empire until it ceased to be ruled by Sith leaders whose infighting he felt was holding it back from its promised rise to glory and strength.
However, in the course of defeating the Eagle, Cipher Nine had obtained half of the Eradicator command codes. Jadus attempted to recruit Nine to execute his plan of firing them, leading to a complicated decision for the agent. All that is known is that Jadus disappeared soon after, his fate unclear. One hypothesis is that Cipher Nine gave him the codes in order to distract him, then sabotaged his ship so the Dark Council and naval reinforcements could move in, and they took him prisoner. Another is that Cipher Nine either talked him down or used the codes to deactivate the Eradicators, with Jadus disappearing once they became useless. Yet another contends that Cipher Nine freely gave him the codes, becoming the «Hand of Jadus.» Jadus then tasked the agent with killing his daughter, Zhorrid, so that he could resume his place on the Dark Council and reshape the Empire according to his image.
In any case, Jadus soon left the reaches of the known galaxy to better enact his further plans in secret, having also learned of the Emperor’s plans to wipe all life from the universe.
Years later, he was listed as a potential suspect in orchestrating the War on Iokath by Lana Beniko, confirming Jadus was still considered alive and pulling hidden strings.
