A female Sakiyan scientist worked as a contractor for the corporation Arkanian Microtechnologies on their re-engineering project during the Clone Wars. She earned a bounty on her head for her efforts, which brought her to the attention of the Gand Findsman Vaskau Farg. The Findsman, who considered her a "witch," tracked her to the planet Arkania, then to the secret Arkanian Microtechnologies installation where the experiments were conducted. There, he confronted her.
