Darth Xarion was a Sith Lord of the Sith Empire during the Cold War with the Galactic Republic who was a rival of fellow Sith Lord Anathel. The two began to battle in the Stygian Caldera nebula, but their conflict soon disrupted Imperial trade, prompting a negotiator to convince them to move their battle elsewhere in the Outer Rim Territories.
They would later rise to the position of Darth during the intervening years, and would sit on the Dark Council by 3630 BBY, as Head of Galactic Influence - a newly created seat that oversaw the former Spheres of Sith Intelligence and Expansion and Diplomacy. Their rival Darth Anathel would also be on the Council as Head of Sith Doctrine.
