Arbet Makt was a Jedi Master known for advocating more experimentation with the dark side of the Force while secretly forcing his students to turn to the dark side using the Sharek Ar Tarma technique. After two of his former students murdered a colleague, he was investigated by his fellow Jedi and exiled, after which he became known as Darth Freir. After he was exiled, his work was carried on by his final pupil, Ashka Summ, who would go on to become Darth Rakena.
