Brotherhood of Darkness

The Brotherhood of Darkness was the last mass gathering of the Sith in history. An army of over ten thousand Sith Lords and their followers, its destruction on Ruusan heralded the beginning of a new order.

For over two thousand years after the Jedi Civil War, the Sith Order was rampant throughout the galaxy, but also bitterly divided. The Brotherhood of Darkness, which had been founded some two thousand years before the Battle of Yavin, had fractured countless times, and the various schismatic sects made little pretense at unity. Many self-proclaimed Sith Lords prosecuted vast, cruel campaigns against each other as well as against the Jedi Order and the crumbling Galactic Republic. The Sith were on the verge of their greatest victory, yet their division threatened to end it all.

Eventually, from amongst the feuding marauders, a charismatic Sith named Lord Kaan arose. He defeated all of his enemies, took the title of "Dark Lord of the Sith", and reuinted the Brotherhood of Darkness with himself as Supreme Leader.
