The Magician’s Nephew
When Digory, Polly, Jadis, Uncle Andrew, the Cabby and Strawberry inadvertently enter a new world using magic rings, they find it an empty void. Aslan appears, and through the power of his singing, calls the world of Narnia into existence.
All the characters immediately feel awe for Aslan. Jadis expresses this as fear and hatred, and before fleeing she assaults Aslan with an iron bar that she tore from a lamp-post in London. Aslan is unperturbed and continues calling plants and animals into existence. The power of his song is so great that even the iron bar, dropped on fertile earth, grows into a functioning lamp post, and toffees sprout into fruit trees. Aslan claims the power of his song will last for a few days.
Aslan then selects several animals that his song has called into existence and gives them the power of speech and reason. He instructs them to look after the all the animals. He appoints the Cabby to be King Frank of Narnia, and brings his wife Nellie from Earth to be Queen Helen.
Aslan explains that Jadis will pose a great threat to the Narnians, and charges Digory and Polly with a quest to acquire a magic fruit to protect the land. He turns the horse Strawberry into a winged horse named Fledge. When the quest is complete, he crowns the Frank and Helen, and advises Digory on how to care for his sick mother.
At the end of the novel, he takes Digory, Polly and Uncle Andrew back to the Wood between the Worlds, without the use of magic rings, and warns them that their Earth is in danger of a similar fate to the dead
