Firenze the Centaur
This mysterious character dwells in the Forbidden Forest and just so happens to be a centaur, part horse, part man. Centaurs are gifted in the ways of Astronomy and Divination, which means they can look at the stars and see into the beyond. Centaurs traditionally like to be with their own kind and are not fond of wizarding folk, although Firenze is a lot kinder than the rest of his herd.
Firenze is one of the friendlier centaurs of his herd. Centaurs don't usually like to talk to humans.
