Callista Ming, originally known as Callista Masana, was a Human Jedi Knight from the planet Chad during the waning years of the Galactic Republic. She was a member of a rogue sect of Jedi, led by Master Djinn Altis, who were accepted back by the Jedi Order during the Clone Wars to take command of clone troopers and fight for the Republic. During the war, she followed Altis into battle on the planet JanFathal alongside a contingent of clones and two orthodox Jedi, Anakin Skywalker and his Padawan Ahsoka Tano, in order to rescue a Republic Intelligence agent, Hallena Devis. After the war, Masana survived the initial stages of the Great Jedi Purge and made contact with other survivors on the planet Belsavis.
