are attacked by Nagini who was disguised as Bathilda Bagshot. They escape, but Harry's wand is badly damaged. One night, a doe Patronus guides Harry to a pond containing the Sword of Godric Gryffindor. When Harry tries to recover it, the locket around his neck nearly kills him. Ron, guided back by the Deluminator, saves him and destroys the locket with the sword, in turn, destroying Voldemort's Horcrux contained in it. In Dumbledore's book, Hermione identifies a symbol also worn by Luna Lovegood's father Xenophilius Lovegood. When they visit him, he tells them of the mythical Deathly Hallows: the Elder Wand, an unbeatable wand; the Resurrection Stone, which can summon the dead; and an infallible Invisibility Cloak. Xenophilius acts strangely, and the trio realize Luna has been captured. Xenophillius summons Death Eaters to catch them in exchange for Luna's freedom, but the three escape. Harry deduces that Voldemort is hunting the Elder Wand, which had passed to Dumbledore after he defeated Grindelwald. Harry also deduces that his Invisibility Cloak is the third Hallow, and his Snitch contains the Resurrection Stone. The trio are captured and taken to Malfoy Manor. Bellatrix tortures Hermione, believing they stole Gryffindor's sword from her Gringotts vault. With help from Dobby the house-elf, they escape to Bill and Fleur's cottage along with fellow prisoners, including the goblin Griphook. During the escape, Bellatrix kills Dobby. Harry has a vision of Voldemort stealing the Elder Wand from Dumbledore's tomb. The trio decide to break into Bellatrix's vault, believing another Horcrux is there. With Griphook's help, they break in, retrieve Hufflepuff's cup, and escape, though Griphook steals Gryffindor's sword in the process. Harry has a vision of Voldemort being informed of the heist and deciding to check his Horcruxes, thus revealing the remaining ones to Harry: Nagini, and one hidden at Hogwarts. The trio enter Hogwarts with help from Dumbledore's brother Aberforth. Voldemort, alerted to Harry's whereabouts, mounts an assault on Hogwarts. The teachers and students mobilize to defend the school. Ron and Hermione destroy Hufflepuff's cup with basilisk fangs from the Chamber of Secrets. Harry discovers that Ravenclaw's diadem is the Horcrux. The trio find the diadem in the Room of Requirement but are ambushed by Draco, Crabbe and Goyle. Crabbe attacks them using a cursed fire, but fails to control it; the fire kills him and destroys the diadem. Meanwhile, many are killed in Voldemort's assault, including
