There is a race in the world who are born to be kings, called the royal family; there is a vocation in the world that exists only to protect important people, called knights.
The royal family was destroyed because they were kings and became history; the knights became legends because they lost their protectors. When the remaining son of the royal family reigned over the world again, the knight also showed his face again.
But this time it is no longer a lonely battle, nor is it the history of a race, nor is it the story of one person.
