Adi Gallia was a female Tholothian Jedi Master during the twilight years of the Galactic Republic. Gallia was a respected member of the Jedi High Council, who served on that august body in the years leading up to the Clone Wars, as well as some time into that devastating conflict. Though the daughter of Corellian parents, Master Gallia was notable for wearing a traditional Tholoth headdress, suggesting she had ancestors from the planet Tholoth.
As a revered Jedi Master of the High Council, Gallia was naturally an exceptionally skilled member of the Order, who completed several notable assignments during her service to the galaxy. Gallia was a key player in the Stark Hyperspace War and served as the chief negotiator during talks aimed at mending ties between warring factions on Malastare. Gallia also participated in the opening battle of the Clone Wars, where her actions saved countless lives.
Despite her undoubted skill, Master Gallia eventually fell to the blade of the feared Separatist General Grievous, during the Battle of Boz Pity, after the treacherous cyborg surprised the Jedi Master by revealing an extra pair of hidden limbs, using the shock it caused Gallia to stab her through the torso with his lightsabers.
