The Minister of Magic, Rufus Scrimgeour, addresses the wizarding media, stating that the Ministry will remain strong even as Lord Voldemort gains strength. Despite the Ministry of Magic’s attempts to maintain an image of stability, the Death Eaters have made major gains after Dumbledore’s death, committing mass killings of Muggles and infiltrating the Ministry itself. Harry, Ron and Hermione prepare for a journey to find and destroy Voldemort’s Horcruxes, with Harry watching the Dursleys depart and Hermione wiping her parents’ memories of her.
Severus Snape arrives at Malfoy Manor to inform Lord Voldemort and his Death Eaters of Harry’s impending departure from No. 4 Privet Drive. Voldemort commandeers Lucius Malfoy’s wand, as Voldemort’s own wand cannot be used to kill Harry, because the wands are “twins.”
Meanwhile, the Order of the Phoenix gather at Privet Drive and escort Harry to safety, using Polyjuice Potion to create six decoy Harrys out of everyone else. During their flight to the Weasley family home at the Burrow, all are ambushed by Death Eaters. They kill Mad-Eye Moody and Harry’s owl, Hedwig, injure George Weasley, and knock out Hagrid. This forces Harry to take over and drive his flying motorbike while fighting Voldemort. In the process, he destroys some power lines and causes a blackout in a Muggle city. After arriving at the Burrow, Harry has a vision of the wand-maker Ollivander being tortured by Voldemort, who claims that Ollivander had lied to him. Ollivander claimed that the only way Voldemort could kill Harry was by using another person’s wand.
Scrimgeour arrives at the Burrow with Albus Dumbledore’s will and distributes three items to Ron, Hermione, and Harry. Ron receives Dumbledore’s Deluminator, Hermione a copy of The Tales of Beedle the Bard, and Harry the first Golden Snitch that he ever caught in a Quidditch match. Scrimgeour reveals that Harry was also bequeathed the Sword of Godric Gryffindor. The minister states, though, that the sword was not Dumbledore’s to pass on and, in any case, is missing.
The Death Eaters kill Scrimgeour. As a result, the Ministry falls to the Death Eaters and they replace him with their puppet Pius Thicknesse who is under the influence of the Imperius curse. They begin persecuting Muggle-born witches and wizards. The Ministry attacks Bill Weasley and Fleur Delacour’s wedding, but they had been forewarned by Shacklebolt’s patronus charm and many escape. Harry, Hermione, and Ron Disapparate to to Shaftesbury Avenue in London. After they are attacked by Death Eaters in a diner, they find sanctuary at No. 12 Grimmauld Place. There they discover that the “R.A.B.” from the false Horcrux locket is Regulus Arcturus Black, the younger brother of Sirius Black. Kreacher, the Black’s house-elf, tells them that Mundungus Fletcher stole the real locket. Kreacher and Dobby apprehend Fletcher, who reveals that the locket is in the possession of Dolores Umbridge. Under the disguise of Polyjuice Potion, the trio infiltrate the Ministry. In the courtroom, Umbridge is interrogating a Muggle-born witch and threatens her, which enrages Harry, who then stuns Umbridge and Hermione successfully retrieves the locket. The trio escape from the Dementors by fleeing into the wilderness after accidentally revealing the location of No. 12 Grimmauld Place to Yaxley, a Death Eater.
