The Grand Duchy of Zebediah was the ruling state of Zebediah Island. Originally known as the Princedom of Zebediah, it was reduced to the status of a grand duchy after it had been conquered by—and subsequently added into—the League of Corisande.
From the Year of God 893 onward, it was part of the Empire of Charis. (BSRA, BHD) Grand Duke Tohmys, however, took part in a conspiracy to overthrow the Charisians, and was eventually tried and executed as a traitor; Hauwyl Chermyn, a loyal Charisian Marine general and commander of the occupation forces in the Princedom of Corisande, was chosen to be the new Grand Duke.
