They dissolve any happy thoughts of people in their path, and Harry, who has known greater sadness than anyone else in his class, is the most vulnerable. The Azkaban guards, called Dementors, have come to Hogwarts looking for Black, and every time Harry sees them, he faints. When the hippogriff injures Harry's adversary, Draco Malfoy ( Tom Felton), it gives ammunition to those who oppose the headmaster, Professor Dumbledore ( Michael Gambon). Meanwhile the fortune-telling Divination teacher, Sybil Trelawney ( Emma Thompson), predicts danger is very near. The new Defense Against the Dark Arts teacher, Professor Lupin ( David Thewlis), befriends Harry, while Hagrid ( Robbie Coltrane) is now teaching the Care of Magical Creatures class, introducing the students to a hippogriff (a sort of flying bird/horse). Scary creatures called Dementors, guards at the wizard prison of Azkaban, are lurking about the school grounds in search of the first-ever escaped prisoner, Sirius Black, who betrayed Harry's parents to Voldemort and may be on his way to Hogwarts to kill Harry. Soon he is back at Hogwarts school for his third year. In HARRY POTTER AND THE PRISONER OF AZKABAN, when his relatives the Dursleys get to be too much for Harry, the 13-year old rebellious wizard packs up and leaves.
