[@DragonofTheWest]The only "Sith" with proper training would be Palpatine and Dooku.  Dooku is a minor noble in the Republic that resigned from the Jedi, and both will need to defect.

You can always be from the Empire but not have formal training, or just be a dark jedi.

Would said Imperial eventually be allowed to "grow" into the Sith/ Darth title?
