Rig Nema was a female Jedi doctor who served the Jedi Order during the Clone Wars, the full-scale conflict between the Galactic Republic and the Confederacy of Independent Systems. At some time during the war, one of Doctor Nema's patients was none other than Grand Master Yoda, who had started to hear the disembodied voice of the late Master Qui-Gon Jinn, much to the Jedi Council's concern.
