Narnian Empire

See here if you are looking for the individual country of Narnia or the Kingdom of Narnia

The Narnian Empire was a great autocratic political unit of several territories, centering around one head nation: the Kingdom of Narnia. Conquered and discovered areas of the Empire also included the Lone Islands, the Seven Isles, Galma, and the six other islands claimed by Narnian King Caspian X.

The ruler of the Narnian Empire was specifically entitled the Emperor or Empress of the Narnian Empire, not to be confused with the title of the leader of the individual Kingdom of Narnia who was entitled the King or Queen of Narnia.
