During the time of the Clone Wars, Marshal Phara spearheaded a coup, with her faction as the instrument, aimed at overthrowing the established government on Vallt, a planet situated in the Outer Rim. On Vallt, Phara's revolutionary sentiments were no secret, though many thought she did not have what it took to challenge King Chai. Phara's offensive was only made possible through an alliance between her faction and the Confederacy of Independent Systems; the Confederacy's interest in Vallt stemmed from the presence of the acclaimed scientist Galen Walton Erso, who was employed by Zerpen Industries on the planet.
