Lii

Lii was a female Dark Jedi and the twin sister of Kaa. She was so similar to her sister that they were sometimes able to trick others into thinking they were simply one individual. They used this trick on the Confederate General Grievous at an unspecified time before the Battle of Geonosis and were able to gain his trust enough to be invited onto his starship. While there, they were able to steal Grievous' collection of Sith lightsabers and flee undetected. However, Grievous was not kept unaware for long, and he tracked them to the acidic world of Dica where he engaged them in combat. Lii and her twin were unable to overcome the cyborg, and they were forced to flee without the stolen weapons.
