First Post
I do agree with the earlier poster who didn't want the Sith to come back, because it would invalidate the meaning of Vader's victory.
(Queue backstory)
If I were to attempt this, I would go even further back into SW:EU history. This Sith we know in the movies and even as early as KotOR are not the original Sith. The originals were banished from the Republic long before for trying to control life itself via the Force. They settled on a distant world and interbred with a near-human species called the Sith, which eventually led to their name.
A long time passed before the Sith Empire was discovered by accident by Republic explorers, leading to the Great Hyperspace War. While they were eventually beaten back, the ancient Sith were not destroyed outright, and have not been re-encountered since. Supposedly Revan (from the original KotOR) left known space to counter some threat hypothesized to be the return of the ancient Sith, but he was never seen again.
All "Sith" encountered from that time forward were actually fallen Jedi who learned Sith powers by studying remnants left behind by the "True Sith."
(End of backstory)
I'd have the True Sith re-emerge as a threat. Perhaps they've been their all along, eluding detection just beyond the edges of known space, and possibly manipulating things from afar.
