Aslan kills the White Witch and the winter covering Narnia vanishes completely. Peter, Susan, Edmund and Lucy are crowned Kings and Queens of Narnia. Aslan leaves but Mr. Tumnus tells Lucy that Aslan will return one day when he is needed again. Years later, a much older Peter, Susan, Edmund and Lucy are riding in the forest when they stumble upon the lamp post near the wardrobe in Professor Kirke's house. The Pevensie siblings exit Narnia, return to Professor Kirke's house and return back to young age (the age when they first entered Narnia). Even though the Pevensie children were in Narnia for years not much time has gone by in England. Professor Kirke walks in and notices the four young ones are back and mentions how he's been wondering where the kids went and asks what they have been doing. Peter says "You wouldn't believe us if we told you" and the Professor replies "Try me."
