The story about centaur

Centaur is a very proud animal, but Firenze seems to be different from other centaurs. In the first film, when Harry was in danger of being locked in the forbidden forest, Firenze let Harry Potter ride on his back, which happened to be discovered by Bain, another centaur. Bain laughed at Firenze as an "ordinary mule". The fifth part, because Firenze promised Dumbledore to be a divination teacher at Hogwarts, he was driven out of the forbidden forest by other centaurs. Later, Umbridge was discovered by horses when he entered the forbidden forest with Harry and Hermione. Umbridge angered the horses and was detained by them because he called them "dirty bastards" and "uneducated animals". Until Dumbledore himself entered the forbidden forest, Umri wizards were rescued. However, centaurs never attack children.

There are many centaurs living in the Forbidden Forest, including Ronan, Bain, Margaret and Firenze, who replaced Professor Trelawney in Harry's divination class in the fifth year.
