Star Wars: 10 Greatest Sith Lords You'll Never Forget

6. Marka Ragnos

Marka Ragnos was an incredibly powerful Sith Lord who took the Sith Empire into a golden age. He was remarkable duellist and was among the most powerful force users of his time.

Under his rule the Sith empire flourished conducting precise, brutal campaigns against it's enemies. This led the empire to regain the strength it lost in centuries past and would provide a platform for the Empire to grow and prosper long after his death. During his rule Ragnos took a young boy by the name of Tenebrae as his apprentice this would prove to be his greatest legacy in years to come.

Just like Nadd even after his death Ragnos lived on, during the period after his death Ragnos appeared to those trying to claim his throne proclaiming only those were the most powerful could control his empire. He was also responsible for crowning Exar Kun as the new Dark Lord and making Ulic-Qel Droma his apprentice.

His spirit lingered on even into the age of the New Republic until he was finally defeated by the Jedi and sealed away in his tomb.
