For the series of star wars explained This is the Father of Anikin Skywalker i'm not trying to spoil anything but i'll give you a back story. He was raised in the Jedi temple in courasant. He and Qui-gon gin were raised together with Dooku and others trained by Joe Koon and Yoda. He became very powerful to the point he almost became as powerful as a jedi master in his sword fighting ability but never became an elite force user. Him and his master Joe Koon were sent on a mission with Qui gon gin because of reports about a Sith or Siths they were accompanied by many other jedi. What they found was horrible. Darth Flare and Kalarsian a dark force user. The two wiped out all the Jedi except Kris and Qui Gon. There master Joe was injured badly and nearly dead. Dooku was lead to the dark side but the two jedi were unaware of his betrayal. The two excaped saving their master but Kris left the Jedi order out of fear for the siths.
