After an freak accident involving Princess Celestia, a magical powered sneeze with golden glitter, and a pony that guides air traffic, Air Marshal is now an Alicorn. Will he become a prince? Nope.
In 1939, at the beginning of World War II, Princess Celestia closes the German Embassy and exiles the ambassador and his staff back to the human world after a group of ponies are found murdered at the edge of the Everfree Forest.
