The Centaur in Crowfall is more than just a normal person whose lower body happens to be a horse. If you want to be archetypical, Centaurs are closer to the Elves of many fantasy settings, an old and arrogant race with designs on conquering everything.

Coleman explains that his love of the race in older games like Shining Force led to the idea of a split: These somewhat bestial creatures that are nevertheless very refined and cultured.
