The Exalted Order of the Damned
one thousand years ago there was a fracture in The August Brotherhood of the Jedi. Some members felt the way to enlightenment was through rigorous training, discipline and upright moral fiber. While others thought that it was best to shed conventional morals like so much materialism. This split led to many members defecting from the Brotherhood. They were unheard from for years until The Republic expanded too far.
The exact date that The Damned returned is unknown. There were scattered reports of corrupt Force users, but there were always reports of those. Every planet was touched by The Force and touched it in turn. Destructive elements were always removed over the years The August Brotherhood of the Jedi had become quite adept at dealing with those elements.
However reports began to surface, these “destructive elements” were hardier and better trained. Some even wielding Jedi swords. It wasn’t until a collection of books called “Memoirs of The Kyoudai” a collection outlining the Jedi philosophy and pointing out it’s failings. A famous line “I’d rather be among the damned and have truth than bound by hollow rules for a shred of enlightenment”. Thus the enemy was known.
