Zayna Tredahl was a horribly mutated, bearded Human female from Corellia, whose life as a circus freak and a perpetual medical test subject was briefly interrupted by a terrorist kidnapping. Although Zayna was biologically female, she had a goatee (and full beard without proper daily shaving) and no breasts. Though Zayna lived with her strange anatomical condition all her life, it did not stop her from falling in love and having children... although oddly enough, her one child, Kafleer Tredahl, was a Twi'lek.
Zayna was kidnapped by a group of terrorists who had been attacking Selonian dens. The kidnapping garnered little public attention at first, until the strange nature of their hostage became known. From that point on, the HoloNet news programs were full of speculations about Zayna, the bearded woman with a Twi'lek son. Chertyl Ruluwoor hired a mysterious spacer to bring her back safely. After her eventual rescue, Zayna briefly went on to do a series of mature transgendered porn films.
The nature of Kafleer Tredahl's other parent is unknown... and probably best left that way.
