Prince of the fаive kingdoms

They say no king can marry for love, nor can the heir(s) to the throne. But there are those who are lucky. Happy fate or Mrs. Luck helped to overcome all obstacles and separation, and united the lovers. Only to live and rejoice, especially since such a desired heir appeared. But if the birth of this baby is planned and he is from birth only a pawn in someone else's game. And the parents? Well, they are no longer needed, and as they say in the famous drama: "The Moor has done his job, the Moor can leave." The young prince has a different fate.
He will have to grow up early and try to save the world, and at the same time himself and his parents. We can only hope that he will succeed the first time, because there is no second attempt.
