Brotherhood of Darkness

The Brotherhood of Darkness was an organization of Sith that rose to power in the last decade of the Galactic Republic's Dark Age. Founded by former Jedi Master-turned Dark Lord of the Sith Skere Kaan, the Brotherhood took the place of the fragmented Sith Empire after slaughtering many of its most powerful lords. Forming the Dark Army, a force of warriors and soldiers meant to rain fire upon Republic worlds, the Brotherhood existed under the leadership of the Sith Council of Lords, constantly warring with the Jedi Order's Army of Light until both armies were utterly decimated at the Seventh Battle of Ruusan.
