Several people have pointed out more or less significant areas where Lewis' "Outline" is not consistent with the text of The Chronicles. For example the "outline" dates Queen Swanwhite , though according to "The Last Battle" she ruled Narnia before Jadis returned (meaning that her reign must have ended before 898). Paul Ford, author of "Companion to Narnia", points out that the text of "The Lion, the Witch and the Wardrobe" states that Lucy and Edmund are one year apart in age, the years given in the timeline for their births, 1930 and 1932 respectively, would put their ages at something more than a year. Devin Brown, author of "Inside Narnia: A Guide to Exploring The Lion, the Witch, and the Wardrobe," uses the timeline as a way to reconcile some of the statements concerning the timing of Aslan's appearances in Narnia with other characters' recollection of those appearances.
