The Magician's Nephew
Digory Kirke is the nephew referred to in the title of "The Magician's Nephew". He first appears as a minor character in "The Lion, the Witch and the Wardrobe", known only as "The Professor", who hosts the Pevensie children when they are evacuated from London and defends Lucy's story of having found a country in the back of the wardrobe. In "The Magician's Nephew" the young Digory, thanks to his uncle's magical experimentation, inadvertently brings Jadis from her dying homeworld of Charn to the newly-created world of Narnia; to fix his mistake Aslan sends him to fetch a magical apple which will protect Narnia and heal his dying mother. He returns in "The Last Battle".
