The Green Serpent

Once upon a time there was a queen who had two twin daughters. She invited twelve fairies who lived in the neighborhood to come and see her daughters. These fairies could transform an ordinary child to the most intelligent and beautiful in the world. But sometimes fairies could wish the baby a lot of bad things if they were angry with something.

There was a great banquet for the fairies in the palace. But at the beginning of the party an old fairy appeared which hadn't been seen for many years. The queen was afraid of her appearing and the king came to her and tried to sit her at the table, but she said that she didn't want to take part in their celebration...  Why did the old fairy come to the king's celebration?
