Magnus was a centaur that lived in the forest near Winifred Whittle's cottage. While initially argumentative with Mathilda Grimblehawk and her partner during their investigation of the attack on the Muggle construction workers, Magnus ultimately escorted the Muggle child Bethany Harrison from the forest on the condition that no other Muggles were allowed into the forest.
Behind the scenes
- Magnus was the first named Centaur who did not live in the Forbidden Forest of Hogwarts. The fact that Centaurs live all over Europe was previously known through Newt Scamander's book Fantastic Beasts and Where to Find Them.
