A Sith cult or Sith sect was a cult that would praise, and often practice, the teachings of the Sith philosophy. Some Sith cults would also worship one or more specific ancient Sith Lords and practice his or her teachings, sometimes even with the goal of resurrecting the ancient Sith Lord. Some cults would also involve a degree of fetishism as they were in possession of items that once belonged to the Sith Lord in question and treated them as relics and sometimes even instruments to gain power.
As with many other types of cults around the galaxy, Sith cults were often led by one (sometimes more than one) charismatic individual that was strong in the dark side of the Force to inspire faith—often accompanied by fear—in his or her followers. However not all Sith cults were Force users, the Cult of Exar Kun being an example of Sith-worshiping non-Force-sensitives.
Sith cults were usually secretive, and not many were known. One of the most influential and powerful is the Order of Revan, in the resurgent Sith Empire, the cult worships the Sith Lord Darth Revan and have members in high places in both the Old Republic and the Sith Empire including even dark council member Darth Arkous.
Tavion Axmis's Disciples of Ragnos wreaked havoc around the galaxy until they were destroyed by Kyle Katarn's apprentice Jaden Korr and other Jedi from Luke Skywalker's Jedi Praxeum. The sinister Prophets of the Dark Side and the splinter Church of the Dark Side showed many Sith cult characteristics.
