Yamato Kamiya was the father of Kale Kamiya. He always fought the temptation of the dark side, as it was very common for his ancestors to fall to evil. He was once a Jedi Master that eventually did in fact turn nearly completely toward the dark side, but died at the hands of Volsung when Yamato appeared to reach the point of insanity and betray the Dark Lord. Some believed that he had followed in almost the exact same footsteps as Anakin Skywalker. Yamato became a spirit in the Force, where he appeared to his son Kale and other close friends of Kale every once in a while. How Yamato was able to return from the netherworld of the Force and redeem himself in such a very short time is unknown.
