Centaurs are a cross-breed of humans and horses. They are generally intelligent and stuborn, but consider magic an obscenity. There are winged centaurs and regular centaurs. Many Centaurs live on Centaur island, but some who have been discovered to have magic talents were exiled. Centaurs are good archers or good with ropes. They also are well educated. Centaurs have very strict rules about being crossbreeds as Chex would learn early in her life. Centaurs are known to play people shoes.
