Revolution
The revolution that led to the independence of the Kingdom of Odrya.
The eastern states in Druin Dria gained increasing autonomy due to a series of inept Driasts and growing cultural differences. They eventually formed a coalition and fought for years with Druin Dria. Much of the war was spent locked in a stalemate, but it was finally ended when Rudolf Aegis led the coalition to a decisive victory in the battle of the white plains.
