After the Krayt-Wyyrlok War, the Dark Lord of the Sith, the resurrected Darth Krayt, took it upon himself to train a sect of Sith assassins unlike any the galaxy had ever seen, in order to eliminate any remaining supporters of the treacherous Darth Wyyrlok. The Ocissors, this new sect, were made up entirely of female members of species generally considered attractive, such as Humans and Twi'leks. The Ocissors quickly gained a reputation as highly effective assassins, who never failed a mission. They tended to target Jedi and Imperial Knights, Fel Empire officials, and Sith Lords who disobeyed Darth Krayt.
