The Dread Masters
The Dread Masters were six powerful Sith Lords who served the Emperor for centuries as prophets, generals, and advisers. Having mastered the Phobis devices, they wield the power to break the minds of entire armies with pure, unadulterated terror.
"Once, I thought myself a monster. I played in rivers of blood and laughed as innocents quaked. Yet when I touched the Dread Masters, I saw that my darkness was but a shadow of true depravity."
