Zhuma is governed by two sisters. Marjanah, the Marchioness, Water-Witch and Protector of the Realm, is a powerful witch who maintains an iron grip over Zhuma's politics. She is considered the only legitimate governor-wizard in Erwt. Her younger sister Serafima, Countess of Zhuma and Chief of State, has no magical powers, but possesses enormous political and economic ability. Together, they have ruled Zhuma for 60 years, growing the minor desert nation into a major economic and cultural power by leveraging mineral riches (especially gold and iron) and building an advanced network of aqueducts and irrigation systems to support the population.
