STAR WARS: Rebels - The Teachings of Darth Traya.
KebbyVA for Darth Bane
An ancient and legendary Sith Lord, it was Darth Bane who saw that the Sith traditions of old were ultimately a dead end. All too often, squabbling Sith in their bid for power upended carefully laid plans. After the Sith were decimated by the Jedi Knights of a thousand years ago, Bane enacted the Sith rule of two: there would be only two active Sith at one time -- a Dark Lord to embody the power, and an apprentice to crave it. These Sith would operate in the shadows, favoring guile and conspiracy to bring down their opponents rather than brute force -- that is until it was time to rise and subjugate the galaxy.
Darth Bane should sound like his voice actor, Mark Hamill.
"The Sith killed each other. Victims of their own greed. But from the ashes of destruction, I was the last survivor."
"There are no other Sith. There never will be, except for us. One Master and one apprentice; one to embody the power, the other to crave it.
"Power is its own purpose. To share it is to dilute it. You delude yourself, pretender--your order will yet turn on itself and you."
Forgot to mention, first half is the raw audio, the second half is the edited version.
