Son of Ja'rod, Duras was named after the powerful house that he was born into. Held a seat on the Klingon council by 2366 and led the cover up of the treachery involved with the Khitomer Massacre to make all signs point to Mogh. He then attempted to kill Picard and Kurn to prevent the truth coming out, but failed, yet the truth remains covered up to prevent a Klingon civil war. By poisining Chancellor K'rnpec he rose up the ranks to become a contender for Chancellor himself, and tried to kill his competitor, Gowron, with a bomb. During this period he killed K'Ehelyr, Worfs mate, for getting too close to the truth of Khitomer and was killed for revenge by Worf.
