Suppose... suppose we have only dreamed and made up these things like sun, sky, stars, and moon, and Aslan himself. In that case, it seems to me that the made-up things are a good deal better than the real ones. And if this black pits of a kingdom is the best you can make, then it's a poor world. And we four can make a dream world to lick your real one hollow.
How dare you threaten me!
As for me, I shall live like a Narnian even if there isn't any Narnia. So thank you very much for supper. We're going to leave your court at once and make our way across your great darkness to search for our land above!
