He later ruled the Sith Empire of Korriban and Liberated Systems jointly with Darth Vethra and Darth Threx as part of the First Korriban Triumvirate. Exius extended his life unnaturally through concentrated use of the dark side of the Force; prolonging his life to further serve the Dark Lords of the Korribanite Empire.
