Amedda was present when Palpatine offered an explanation for clone trooper Tup’s madness, hiding the true nature of the inhibitor chips placed in each clone’s brain.

Amedda assisted Palpatine in the Sith plot to take over the Banking Clan, using Rush Clovis as an unwitting pawn in a conspiracy that gave the Supreme Chancellor even more power over an increasingly militarized Republic.

In the final days of the Clone Wars, Palpatine sought to draw Anakin Skywalker into the Sith web, having groomed him as a new apprentice to replace Count Dooku. Amedda was in the Supreme Chancellor’s box at the Coruscant Opera House when Palpatine summoned Anakin for a critical meeting.

When Palpatine declared himself Emperor, Amedda was at his side, watching with satisfaction as the Senate cheered the end of the Republic.

Amedda watched impassively as Yoda confronted Darth Sidious in the Supreme Chancellor’s office beneath the Senate chamber. He then departed, certain that his Sith master would prevail against the Grandmaster of the nearly extinct Jedi Order.

Amedda retained his power in the Galactic Empire, serving as its Grand Vizier and earning a reputation as one of the Emperor’s most-feared servants. Military leaders such as Grand Moff Tarkin heeded his summons on behalf of Palpatine, while governors such as Arihnda Pryce dreamed of being thought worthy of Amedda’s attention.
