Darth Wrend

Darth Wrend was a legendary Sith Lord who fought against the Jedi Order and was believed dead, only to return and fight them once again. Around 67 BBY, Jedi Padawan Qui-Gon Jinn wondered whether a prophecy in the holocron of prophecy about evil returning once "the righteous [lost] the light" referred to Darth Wrend rather than a potential reincarnation of the Sith Order as believed by others who had known the prophecy.
