This is just an overly nickpicky excuse to put something up on this empty board, I know, but I'm sure no one will mind a little nickpickiness.

Aslan's favorite catch phrase in this book is, "No-one is told any story but their own." I suppose he wasn't breaking his own rule, then, in The Silver Chair, when he tells Jill about Caspian and his lost son. There could be other instances where Aslan tells someone someone else's story, but I'm too lazy to look for them.

I don't think this is breaking the rule because the issue of Caspian and his son becomes part of Jill's story. does that count?

The problematic elements of Calormen are from Lewis's ignorance, rather than racist intent. In The Last Battle, he paints racism as stupid and idiotic.
