Crystal, a Twi'lek of the female persuasion, managed the troupe of dancing girls belonging to Toobu, the Hutt, on the moon of Nar Shaddaa. In the time of the Galactic War, she was met by a Sith accompanied by Vette, who sought her sibling, Tivva; Crystal kindly showed her where Tivva was. Subsequently, the Sith purchased Tivva's freedom, and after expressing her gratitude to Vette, Tivva departed, assuring them she would remain in contact.
