The youngest daughter of the politically influential House of Duras, B'Etor and her elder sister, Lursa, have been linked to numerous anti-Federation (and anti-Klingon) activities. Most notable was an attempt to overthrow the Gowron leadership and impose the tyrannical leadership of Duras' illegitimate son, Toral, into the Klingon High Council. With this political maneuver, B'Etor and Lursa had found the spark to ignite Klingon factions into a bloody civil war. When it was uncovered that the two sisters had conspired with Sela and the Romulan Star Empire, the civil war came to a close, and B'Etor, along with her sister, both went into exile for nearly two years. In 2369, the sisters supplied bilitrium to the Bajoran terrorist known as the Kohn-ma. Recently, the Enterprise has reported that B'Etor and her sister, are in collaboration with one Dr. Soran for yet unknown reasons. Obviously, the Duras sisters are considered extremely dangerous enemies of the Federation of Planets.
