"Are we done with your sparring lesson Master Kenobi? I still have the fate of the galaxy to discuss with you."

From the depths of the Galaxy emerged an ancient Sith Lord, from a race long desolate and forgotten. One who due to talking to much, (usually negatively about the plans of those above her.) Separated from the Sith order long before the old republic. But she neither allied with the Jedi order. Instead she roams the remote corners of the galaxy and now servers to balance the force, whether by killing off Sith, whole planets, or even Jedi that she deems unworthy. Abounding with incredible wisdom (hence the name "The Seer") rarely ever uses her lightsaber in combat, but instead utilizes the force like never seen before.

Here she finds Obi Wan Kenobi on Tatooine after the rise of the empire. And proposes to end the Emperor and his apprentice Darth Vader. He of course fights her sensing the dark side, but is meet with a Saber instruction the like of which he has not had the insolence of enduring sense he was a padawan.
