centaur

They are a cross between human and horse, the bottom half being horse and the
top half-human. The horse half of a centaur is very sleek, graceful, and 
elegant. The human half has all the range of appearance of humanity. 
Centaurs are surprisingly gentle creatures, though they can fight quite 
well when provoked. Usually they stay away from magic, but it is fact they 
were once created by magic. Centaur tend to choose a life of protecting 
the weak and oppressed, and they will rarely walk past a creature in 
distress. They see themselves as protectors of life and keepers of the Realm.
