The so-called "Sith Witch of Mustafar" was rumored to be a witch of the Sith order, making her home on the volcanic world of Mustafar. The Legend of the Sith Witch describes her as a disruptive presence, sowing terror wherever she went. An enraged cry, the trembling of the woods, and a radiant glow illuminating the swale heralded her presence. Darth Vader shared the tale with his master, Darth Sidious, but the Sith Lord disregarded these omens. After incorrectly identifying a lava flea, a squad of stormtroopers, and even R2-D2 as the witch, the aforementioned individuals became certain of her arrival upon seeing a brilliant flash of light.
