After receiving Numa's training, Numa and Perkute undertook the Massacre of Morc; the two killed all of the inhabitants of the planet Morc and named it the site of a new Sith order called the "Dark Order of the Sith." He and Numa recruited and trained thousands of Sith Lords, planning to eventually topple the New Republic and take revenge on the Jedi. Perkute was chosen to be the leader of the group of Sith Lords who were chosen to reveal themselves to Emperor Cinsort of the Imperial Outer Rim Territories. During the Galactic Black War, he led the Shadow Troopers, a group of Sith and elite members of the Imperial Black Army.
