In the case of the One Sith, various Chagrian Sith Lords, each bearing in turn the name of Darth Wyyrlok, bore the title while the One Sith's leader, Dark Lord of the Sith Darth Krayt, went into stasis. The Regent was considered the "voice" of the Dark Lord and commanded in his stead. By 137 ABY, a third Wyyrlok assumed control of the One Sith as regent after killing the Dark Lord on Had Abbadon.
