Aslan is a force for good in the novel, and so the fact that the Calormenes regard Aslan as a demon is a sign of how corrupt Calormene culture can be. Aslan’s status as someone higher than any Narnian King reflects that idea in Christianity that God is a sort of king above any mortal ruler. Although Shasta is afraid during his encounter with the mysterious Aslan, the grassy hillside and birds that Aslan leaves behind show the beauty of nature and ultimately suggest that Aslan is a benevolent figure—just like the powerful but generous Christian God.
