Krath/Legends

The Krath was a secret society founded by Dark Side dabblers Aleema and Satal Keto some 4,000 years BBY, in the Empress Teta system, it was named after the demon from the fairy tales of their youth. The Krath developed into a Dark Side magical sect that ruled the system. They also lent support to the Sith Lord Exar Kun, since one of the major members of the Krath was Kun's apprentice, Ulic Qel-Droma. Leia Organa Solo learned about the Krath while using a knowledge-filled Jedi Holocron. The Krath developed a powerful War Droid which was designed for the task of slaying Jedi. The droids were just as lethal as intended, annihilating every one of their targets when dropped en-masse into Jedi temples.
