Darth Bane dynasty of evil : a novel of the Old Republic

Twenty years have passed since Darth Bane, reigning Dark Lord of the Sith, demolished the ancient order devoted to the dark side and reinvented it as a circle of two: one Master to wield the power and pass on the wisdom and one apprentice to learn, challenge and ultimately usurp the Dark Lord in a duel to the death. But Bane's acolyte, Zannah, has yet to engage her Master in mortal combat and prove herself a worthy successor. Determined that the sith dream of galactic domination will not die with him, Bane vows to learn the secret of a forgotten Dark Lord that will assure the Sith's immortality--and his own.
