Mas Amedda was the Vice Chair of the
Galactic Senate during
Chancellor Valorum's term, a position he continued to hold as Chancellor
Palpatine's transformed the Republic into the
Galactic Empire. Amedda's booming voice often called for order when the partisan nature of the Republic's government degenerated into pointless bickering. In an alien gesture of authority, he would often punctuate such calls with a flicker of his long, forked tongue.
Amedda was fully aware of Chancellor Palpatine's Sith allegiance as the Clone Wars drew to a close. He tasked Palpatine's personal clone troopers to scour the Senate for any traces of the fugitive Jedi Master, Yoda.
