Sidri-Ashak served Brazollus Dor during his reign between Reman Cyrodiil II and Reman III. Dor, who was not a capable ruler, nor interested in political affairs, assigned the duties that an Emperor would usually perform to his potentate, Sidri-Ashak. This is considered Dor's only wise decision, as Ashak proved to be a gifted administrator and man of integrity.
Little is known what Ashak did during his time as Potentate. Mysterious green runestones dotted the land of Cyrodiil after he made an effort to improve the province's roads. He also wrote a book titled Recollections of a Humble Potentate, which was later read by High King Emeric of the Daggerfall Covenant.
