Background
Centaurs in Narnia are among the most majestic and intellectually serious of the old creatures. Lewis gives them a particular dignity. They are associated with star-lore, counsel, battlefield strength, and a grave awareness of the larger patterns moving through the world.
How the Race Functions in Narnia
When centaurs appear in the Chronicles, they often deepen the sense that Narnia is ruled by more than politics or brute force. They read the heavens, understand times and seasons, and stand close to the older wisdom of the land. That makes them natural counselors in moments of danger.
