Centaur

Centaurs, a half horse/goat, half human hybrid. Noble creatures, they have great pride and will be truly vicious to any that disrespects them. They are commonly found in two different areas, the Gaping Canyon, and the various forests of Vatain. While they may be found in mountainous terrain, it is highly unlikely, as the various denizens of said mountains are quite excellent at destroying invaders.
