Eventually, Jarrus would wind up as a freighter pilot for the corporation Moonglow Polychemical in the Gorse system, piloting Moonglow-72. After getting caught up with a ragtag rebellious group consisting of Twi'lek pilot, Hera Syndulla, the conspiracy theorist Skelly, and the Sullustan shift leader Zaluna Myder, Kanan helped prevent Count Denetrius Vidian from destroying Cynda. During the conflict, Jarrus made the decision to accompany Syndulla on her VCX-100 light freighter, the Ghost—which he eventually would command alongside her. Later on, he would develop a romantic relationship with Syndulla.
While cocky and often sarcastic, Jarrus was eager to fight the Galactic Empire. Five years before the Battle of Yavin, Jarrus met Ezra Bridger, a fourteen-year-old Force-sensitive Human, whom he decided to mentor.
Later Kanan and his apprentice, accompanied by Ahsoka Tano, would travel to the planet Malachor to learn about the Sith. However, this decision would have costly results, as Kanan would be rendered blind by a lightsaber strike from the formerSith Lord Maul at a Sith Temple on the planet.
