Age of Heroes
The Third of The Five Kingdoms, the Altranian Union is a Constitutional Monarchy nominally made up of 6 constituent local governments called Prefectures which has sovereignty over the Altranian Plain, from which it derives its name. It is currently ruled by King Brandis Copperhand of the Jardine Dynasty, who have ruled it since Radren the Conqueror united the 6 tribes.
It is the only one of the Five Kingdoms which still remains, and as such is considered to be the dominant power on The Continent. It is also the trading hub of The Continent, though its ability to conduct trade has been lessening as the roads become less traveled and less safe
