Sith Lord

Sith Lord was a title that was conferred on a powerful master of Sith knowledge. Yet, the title seemed to be used somewhat ambiguously to refer to various things, including all Sith, the Dark Lords of the Sith, Sith Masters in Darth Bane's reformed order, or as a rank akin to that of the Jedi Master for the Jedi Order. Several Sith Lords also held the Darth title. The term "Sith Lord" generally encompassed members of both sexes, although some female Sith, such as Lumiya, were styled Sith Lady.

Originally, "Sith Lord" referred to a high-ranking member of the Sith race's society. As the Sith civilization progressed, many claimed the title; Adas was one such Lord. Sith Lord was the dark-side equivalent of Jedi Master.
