Phantom Princess (Online Hoax)

Origin
In 1940, the Nazis invaded the fictional European country of Slivonia. Since the Slivonian Royal Family was held in such reverence as to be almost worshipped, the invaders decided to strike a symbolic blow to fill the populace with despair. That blow? Slaying every member of the Royal Family.

The corpse of the 16 year old Princess Tatanova disappeared and soon after, the German occupiers began dying in grotesquely violent ways. Rumors spread that the ghost of the young Princess was avenging herself and the nation on their conquerors.
