Sith Master/Legends

"What is thy bidding, my master?"

- Darth Vader

Sith Master was a title taken by a Sith if they had an apprentice.

History
In the time of the Jedi Civil War, Darth Malak was sometimes referred to as a Sith Master, being the Dark Lord of the Sith and having an apprentice, Darth Bandon. Headmasters of the Sith Academy on Korriban, Jorak Uln and Uthar Wynn, held this title but it is unknown if they held the title of Sith Lord or not.

In Darth Bane's Sith Order, the Sith Master and the Sith apprentice both held the title Dark Lord of the Sith simultaneously, unlike the earlier tradition of a sole Dark Lord.

In Darth Krayt's Sith Order, the Rule of Two is abolished, but the tradition of master and apprentice is still in use.
