"The Empire seems to structure itself pretty much like the Brotherhood of Darkness from the Darth Bane books. In those books Bane learned from Darth Revan's holocron that the Sith will weaken if they keep up the "colectivist" ways, due to their natural instinct to turn on each other (which, according to Revan is innevitable and is simply the way the dark side works). In order to prevent weaker Sith to join and plot together and overthrow a stronger Sith then Revan implies that the True Sith lords must be reduced to two in number so the master is only overthrown if the apprentice proves stronger and challenges the master, hence ensuring the order keeps getting stronger. And that is way i betrayed my assignment to purge the order of Revan in this game... I joined them, even though most of the "facts" they preached about Darth Revan were only partially true and even though they are all a bunch of loonies. xD"
