The document is a letter from an 8-year-old girl named Ilushina Alena describing her dream holiday. She wants to spend a month at an ancient white stone castle located on the shore of an emerald lake, surrounded by big beautiful mountains and a small forest. She plans to take one of her friends, who also dreams of this holiday. The letter also shares a fairy tale about an ordinary village girl who was given to a dragon but instead of eating her, he fell in love and was transformed into a human by his love for her. They married and lived happily in their wonderful castle.
