Renau was a Moff of the Galactic Republic and later Grand Moff of the Galactic Empire. During the Clone Wars, Renau was promoted to the rank of Moff and placed in command of the Eleventh Army, also known as "Blazing Claw Command". The 11th Sector Army was charged with protecting the Gordian Reach Oversector, an area that Renau effectively had complete power over. After the rise of the Galactic Empire in 19 BBY, Renau retained command of both the Sector Army and sector itself.
