Herdessa was a Mid Rim world on the Corellian Run. A peaceful planet, many diplomats and others of affluence could remain neutral in debates. It was represented in the Galactic Senate by Shea Sadashassa.
In the time of the Galactic Civil War, it was controlled by the Herdessan Guild. During a diplomatic mission to Herdessa with Mon Mothma to overthrow the Herdessan Guild, Leia Organa first encountered a mysterious cyborg named Lumiya.
