7. Qui-Gon Jinn
Qui-Gon Jinn was a Jedi Master who was perhaps just as important in death as he ever was in life. Born on the galactic capital of Coruscant, Qui-Gon joined the ranks of the Jedi Order as a young boy and quickly became one of the most talented Force users of his time.
Jinn started off his career as a Padawan under Dooku, who would eventually abandon the Jedi and become the Sith Lord Darth Tyranus. This event had a profound effect on Jinn, who would go onto become a Jedi Master himself and take on his own apprentice, Obi-Wan Kenobi. However, Dooku’s abandonment would also make Jinn weary of the stringent Jedi Code that he had grown up with.
By Kenobi’s accounts, and by his own admission, Jinn viewed the Jedi Order as righteous, but flawed. These were lessons that he would impart in Kenobi, who would, in turn, impart these lessons in his own apprentice, Anakin Skywalker. These lessons were perhaps prophesied in the Chosen One who would bring balance to the Force.
Jinn would die nearly ten years before the onset of the Clone Wars in a duel with Darth Maul. However, with his dying breathe, he was able to pass on his final words of wisdom to Kenobi: to train the Skywalker boy as his own, as he was the Chosen One. As he passed away, he found ways to commune with Kenobi through the years as a Force spirit.
This would begin a trend of Jedi who could interact with the physical world beyond death, such as Kenobi and Master Yoda. This ability was likely taught to them by Qui-Gon Jinn, and allowed the Jedi to leave a legacy even after their demise.
