Editing Albus Dumbledore (section)

===''Harry Potter and the Half-Blood Prince''===
In ''[[Harry Potter and the Half-Blood Prince]]'' (2005), Dumbledore brings Harry along as he attempts to persuade [[Horace Slughorn]] to rejoin the Hogwarts faculty. Harry notices that Dumbledore's right hand is shrivelled and blackened. During the school year, Dumbledore uses the [[Pensieve]] to teach Harry about Voldemort's life and his rise to power. In one of the Pensieve visions, Harry witnesses Dumbledore's first encounter with the young Tom Riddle. Dumbledore had known from the beginning that Riddle was dangerous, but believed that Hogwarts would change him.

Dumbledore and Harry learn that Voldemort created six [[Horcrux]]es to gain immortality, and that they must be destroyed before Voldemort can be killed. Harry repeatedly warns Dumbledore that [[Draco Malfoy]] is an agent of Voldemort, but Dumbledore refuses to take action against Draco. He tells Harry that he already knows more about what is happening than Harry does. Near the end of the novel, Dumbledore and Harry enter a cave in search of a Horcrux. Dumbledore drinks a potion inside the Horcrux's container and begins to scream in agony. When Harry attempts to retrieve some lake water for Dumbledore to drink, he is attacked by [[Inferius|Inferi]] that reside in the lake. They try to drown Harry, but Dumbledore rescues him.

Dumbledore and Harry arrive in the Hogwarts [[Magic in Harry Potter#Astronomy|Astronomy Tower]] with the Horcrux. Dumbledore asks Harry not to interfere in the events that are about to take place, and puts him in a body-binding curse. Immobilized, Harry is unable to intervene as Draco arrives and disarms Dumbledore. Several other Death Eaters then enter the tower and try to persuade Draco to kill Dumbledore. When Draco hesitates, [[Severus Snape]] appears and performs the killing curse on the headmaster. His funeral is attended by students, Hogwarts staff, members of the Ministry of Magic and others. He is entombed in a marble [[sarcophagus]] beside the Hogwarts lake.
