The Flame Order was an order of Force adepts banned from the Jedi Order. They were called so because of the orange lightsabers they wielded. They were very fond of the dark side, but kept that a secret during their time with the Jedi Order. The initial reason for their exile was because they started new ideals, such as a new rank system, and then started trying to force it on the Jedi. A dark side power slipped, and they were banished. They traveled to a remote world, then enforced their rules. They were considered very uncivilized, and based their system around barbaric behavior.
