Zan Fyar was one of Cadden Blackthorne's earliest students in the Force, and a promising Guardian of the Force. He was trained by Cadden before the Jedi Master fell to the Dark Side, and when Blackthorne disappeared, Zan was forced to teach himself what was left to learn. When Cadden returned to Udine as Darth Trayus, he took Zan on as his apprentice, naming him Darth Invictus. Zan was charged with the conversion of the Jedi that followed him into Dark Jedi, while Cadden set off in search of more allies to his cause.
