The Sith were the most powerful and prominent Dark Side users\. They drew their power from anger, hatred, and the Dark Side of the Force. The term "Sith" was originally attributed to a species strong in the Dark Side, but later the name broadened to refer to an Order of Dark Side users.
A group of fallen/Dark Jedi encountered the Sith Species upon being exiled to the Outer Rim after the Great Schisims with the Jedi Order. They intermarried with the Sith species, having offspring that were strong in the Force and achieved mastery over the Sith species. Some example were Naga Sadow and Marka Ragnos.
