History
Castile D'or is a principality in Europe. Its exact geographical location is not known. It was ruled by the evil Queen Ursula. After being involved in an European conflict that saw fifteen million people dead, Queen Ursula was forced into exile to an island in the Atlantic.
By 1939 Queen Ursula came out of her exile, regained her throne and began a campaign of bloody retribution against her earlier enemies, neighboring country of Attania.[1][2]
American pilot Perry Webb, also known as the American Ace, was in the region when the war sparked off, and soon found himself assisting the Attanians.[3]
