June 28, 1914.

Archduke Franz Ferdinand and his wife are struck down by the bullets of serbs anarchists. But they're not the only victims of the Black Hand : her Highness Celestia, Princess of Equestria is also killed in the attack.

Equestria wants revenge for the death of its leader, and stands ready to ally itself with the Central Powers in the first World War of the XX° century : the Great War.

Original story by me.
