A Survivor of the Clone Wars, Kanan Jarrus formerly known as Caleb Dume was a Jedi Padawaan at the time of his master's execution at the hands of clones during Oder 66.
Trained under Depa Billaba, Kanan was a mere child during the wat, however he and his master both saw their fair share of combat through the conflict. When the Empire rose and Order 66 was initiated, Depa sacraficed herself to allow her student to flee. A descision, though ordered, Caleb would regret through most of his life.
As the years dragged on, Caleb would change his name and alter his idenity to Kanan Jarrus to avoid any connection as a Jedi.To survive, he would eventually become a mercenary, and later join the Rebellion as one of Phoenix Squadron's top operatives.
Though, never officially knighted, Kanan would live on to teach a young orphan by the name of Ezra Bridger. A gifted student in his own right, Ezra's relationship with Kanan would soon grow into a close bond - like a second father or brother, even despite their often disagreements. Still, in the end Kanan proudly served and taught Ezra to the best of his knowlege and the two would continue on to learn together up until his apparent death on Lothal.
