Sith

Despite what Jedi would like to think, Sith are not as extinct as they are believed to be. Many of them still lurks in the shadows.

Some lived and continued their ways since 'New Sith Wars', some created their own cults/kingdoms/organizations that exist to this day. A prime example being Prophets of the Dark Side.

In ancient tombs, the spirits of long dead Sith Lords await for a chance to return and shake the galaxy once again – either by possessing individual or training her.

There are also many organizations and individuals, who despite not being Sith, follow their ideology and use dark side – dark Jedi, Ember of Vahl and Nightsisters of Dathomir being prime examples.

And of course, there exists Darth Sidious and his followers.
