Darth Malcadius

""As dark as the shadows he dwells in, Darth Malcadius is the last true Sith"

-Kai Jadi Yen

Jarvalus Malcadius, also know as Darth Malcadius, was the Supreme Ruler of the Grand Sith Empire and a powerful Sith master. During the release of Malcadius' Master Plan, he stole the cloning machines on Kamino, and advanced them to clone individual Sith knights. He then led an onslaught on the galaxy, establishing the Grand Sith Empire and destroying many races, including the Trandoshans and the Geonosisians.

When he was informed on Kai Jadi Yen's insane plot to find the son of Jedi legend, Yoric Mandaoe, Malcadius ordered a battalion of his finest Siths to execute both of them, who were defeated thanks to Kai's adept Jedi skills. Malcadius, using his Hellfire Station, destroyed the planet of Bespin; killing Yoric's wife and eliminating the Bespin Covert Base in the process. Yoric's son becomes enraged and leaves for Malcadius' base, and Kai is forced to follow. While Malcadius kills Kai, the young Padawan slays the Sith Lord and peace is restored to the galaxy.
