Unidentified rogue Jedi

During the days of the Old Republic, a male individual served as a member of the ancient Jedi Order. At one point during his life, the Jedi began studying the forbidden arts of the Dark side of the Force. He came to believe that the true potential of a Jedi involved tapping into the Dark Side, as opposed to embracing serenity and the light. The Jedi Council, upset by the beliefs of the Jedi, exiled him from the order, although he was able to garner enough followers to oppose his former brothers and sisters. The conflict that ensued became known as the Hundred-Year Darkness. Eventually, he would establish the Order of the Sith Lords, who would go to the planet of Moraband to practice their dark tradition.
