“ I can give her no greater power than she has already,” said the women; “don’t you see how strong that is? How men and animals are obliged to serve her, and how well she has got through the world, barefooted as she is. She cannot receive any power from me greater than she now has, which consists in her own purity and innocence of heart.”     

                          From Hans Christian Andersen The Snow Queen

Anna’s true power lies in the purity and innocents of her heart. Remember that it is Anna’s heart of gold that was the real magic. That enchanted everyone she meat. Bringing out the best in them and reviling and reversing the true evil and weakness. Be it a troll in disguised or a lost little girl living in fear. Anna brought the true miracles to the story. That is why she is the hero. Anna is one of a kind.
