Divine providence
After meeting King Lune of Archenland and warning him of the impending Calormene invasion, Shasta becomes lost in a fog and separated from the Archenlanders. While walking in the fog, he senses a mysterious presence nearby. Engaging in conversation with the unknown being, Shasta tells of his misfortunes, including twice being chased by lions. His companion, who turns out to be Aslan, responds as follows:
"I was the lion who forced you to join with Aravis. I was the cat who comforted you among the houses of the dead. I was the lion who drove the jackals from you while you slept. I was the lion who gave the horses the new strength of fear for the last mile so that you should reach King Lune in time. And I was the lion you do not remember who pushed the boat in which you lay, a child near death, so that it came to shore where a man sat, wakeful at midnight, to receive you."[4][5]
The incidents which Shasta perceived as misfortunes were orchestrated by Aslan, in his Divine Providence, for greater purposes.[6][7]
"Narnia and the North!"
Bree and Shasta use the phrase "Narnia and the North" as their "rallying cry" as they make their escape from their life in Calormen. They are both motivated by a deep longing to find their way to their true homeland. In the setting of The Horse and His Boy, the reader finds a departure from the landscapes, culture, and people of the Narnian realms which have become familiar in the other books. The placement of the action in the realm of Calormen helps to convey a sense of "unbelonging" on the part of the characters and the reader, which reinforces the motif of longing for a true home.[8]
