Aslan is the central lion character and creator of Narnia in C.S. Lewis's novels.
Aslan appears throughout the Chronicles of Narnia as a powerful, wise, and compassionate figure. In The Magician's Nephew, his song brings Narnia into existence and awakens its living creatures. He is therefore more than a character within the world: he is presented as its creator and ultimate authority.
Aslan's most prominent early appearance is in The Lion, the Witch and the Wardrobe. He offers himself in place of Edmund after Edmund's betrayal, is killed on the Stone Table, and returns to life through the deeper magic. This episode is one reason readers commonly interpret Aslan as a Christian literary symbol.
Lewis resisted reducing the character to a simple allegorical code. He described the Narnia stories as imaginative fiction in which Christian ideas appear through a different world. Aslan also appears in the series finale, The Last Battle, where he judges the inhabitants of Narnia and brings its story to an end.
