It is my wish to plant in Narnia a tree that she will not dare to approach， and that tree will protect Narnia from her for many years. So this land shall have a long， bright morning before any clouds come over the sun. You must get me the seed from which that tree is to grow.”

“Dear son，” said Aslan， “I will tell you what you must do. Turn and look to the West and tell me what do you see？”
