Once upon a time there was a great king who had ruled his country for many years. He also had a beautiful daughter, who grew up with frogs and dwarves, but that is completely irrelevant to this story.
The king had learned to protect his kingdom successfully against invaders and raids and had fought many a battle. He had a big, strong army, so nobody dared to attack; there was peace in his country for a long time.
But more and more travellers reported incredible changes in other parts of the world. Previously unknown kingdoms rose rapidly, while others disappeared into insignificance at the same speed.
