Corran Horn was the grandson of a Jedi Master who fought in the Clone Wars, a fact he didn’t discover until later. He served in the Corellian Security Force before enrolling at Skywalker’s Jedi Academy. In due time, he would rise through the ranks to become a Jedi Master.
His knowledge in the Force became so vast that he was eventually called to join the Jedi Council. Horn was unusual among Jedi for his lack of telekinetic skill, but he was exceptional as a lightsaber duelist, energy absorption, and Jedi mind domination.
