Darth Organius is the reigning Galactic Empress and the Dark Lord of the Sith. Born in 19 BBY as Leia Organa on Coruscant, her name was disregarded by her father, Vader, and she was his Sith apprentice, bearing the name "Darth Organius". She continues to reign under this name. Like Palpatine before her, Organius is an extremely evil person. She feeds on the life energies of those around her, and makes the Universe suffer while in pain. [Source]
