Shea Sadashassa was a senator who represented Herdessa in the Galactic Senate of the Galactic Republic and was part of the Delegation of 2,000. One day after the formation of the Galactic Empire, Imperial Intelligence conducted a mass arrest of senators, which included Sadashassa. Sadashassa continued to serve in the Imperial Senate, secretly collaborating with the Alliance to Restore the Republic as a rebel collaborator. Sadashassa was later imprisoned along with fellow sympathizers in the Arrth-Eno Prison Complex, during which Sadashassa was killed during the Arrth-Eno Mission when Emperor Palpatine became aware of the mission and laid out a trap.
