A Sith sorcerer or sorceress is an individual who is proficient in the arts of Sith magic, using spells, talismans or incantations to focus the power of the dark side. They were discovered during the time of the original Sith Empire. Sith sorcerers gained their powers through intense study of Sith traditions, and applications of the dark side of Force. Occasionally, an aspiring sorcerer's powers were developed through sheer innate talent, rather than harnessing them through study, or spontaneously, or being bestowed upon them by another source. The term was synonymous with Sith magician, with females who dabbled in Sith magic being sometimes referred to as Sith witches.
Sith sorcerers were not always Sith Lords. Queen Amanoa and King Ommin were both Sith sorcerers, having been apprenticed to Freedon Nadd, but neither one attained the rank of Sith Lord. On the other hand, Naga Sadow, Freedon Nadd, and Exar Kun all were Sith magicians and Sith Lords simultaneously.
The term was also used for Sith Inquisitors who fought for the Sith Empire during the Great Galactic War and the Cold War that followed it circa 3,653 BBY. These Sith specialized in ranged attack abilities with the Force, such as Force lightning and Force drain. Sith Sorcerers were known to primarily wield one lightsaber in combat, and were adept at variant applications of Force lightning in combat.
