When people discovered the continent known as Hirshein, war broke out as eight cities were formed. People fought over simple things as they attempted to take land and resources from one another, pushing back and forth as they slaughtered. Out of the many people that came to Hirshein, only eight were brave enough to stand against the war. These people left the quickly forming cities in search of a cure for the madness, what they found was Magic. An ancient power locked away deep in the caves of the tallest mountain in Hirshein, when they came back several years later, they returned as what would later be called Arch-Mages. They stopped the war between the Eight Cities Of Hirshein and from then on the continent lived in peace, and over time the Thaumaturges had children. Magic was passed down in bloodline, but it was never quite as powerful as the first eight who would become known by the name; The Old Masters, as well as Arch-Mages. All holders of Magic from then on were known as Mages, until a young girl named Valryn Karyn discovered the power inside her. With the power of The Old Masters, Valryn finds herself thrust into a terrifying new world... the world of Mages.
