Flint

Flint was one of many Dark Jedi who served the Galactic Empire, but Flint was the protege of Darth Vader himself. Following Vader's and Palpatine's deaths at the Battle of Endor, the former Emperor's Hand Lumiya became the new Dark Lady of the Sith and took Flint as her apprentice. Shortly afterward, however, Luke Skywalker, warned and assisted by the ghosts of Obi-Wan Kenobi, Yoda, and Anakin Skywalker, managed to redeem Flint, who later became a great political figure on the planet Belderone.
