From an early Russian folk tale. A cruel king hears of the birth of the 7th son of the 7th son and of a prophecy has it that this child will grow up to become king of his kingdom. The cruel king decides to kill this 'Luck Child', and throwing the child and Chancellor into the sea, so ends the prophecy. But this is the Luck Child and he survives. Sixteen years later, the king discovers the Luck Child has survived and plots to kill him again. He sends 'Lucky' off to the palace with a letter that has his execution in it; in the forest, Lucky meets the 'Little Man' who drugs him and reads the letter, and the Little Man proceeds to forge new orders. So when the king gets back, instead of Lucky being executed he has instead married the princess. The King quickly says that the marriage can only be when he has the golden feather from the Griffin's back, a man-eating monster. (thetvdb.com)
