Aslan, the Great Lion, is the central character of The Chronicles of Narnia. He is the eponymous lion of The Lion, the Witch and the Wardrobe, and his role in Narnia is developed throughout the remaining books. He is also the only character to appear in all seven books. Aslan is a talking lion, the King of Beasts, son of the Emperor-Over-the-Sea; a wise, compassionate, magical authority (both temporal and spiritual); mysterious and benevolent guide to the human children who visit as well as guardian and saviour of Narnia. C. S. Lewis described Aslan as an alternative version of Jesus as the form in which Christ might have appeared in an alternative reality.
