Following Dumbledore's death, Voldemort has completed his ascension to power and gains control of the Ministry of Magic. Harry, Ron, and Hermione drop out of school to find and destroy Voldemort's remaining Horcruxes. They isolate themselves to ensure the safety of their family and friends. They do not have much knowledge about the remaining Horcruxes except the possibility that two of them are objects that belonged to Hogwarts founders Rowena Ravenclaw and Helga Hufflepuff, and that the third is Nagini, Voldemort's snake familiar. The locations of the two founders' objects are unknown, and Nagini is presumed to be with Voldemort himself. As they search for the Horcruxes, the trio learn details about Dumbledore's past, as well as Snape's true motives.
The trio recovers the first of Voldemort's Horcruxes, Salazar Slytherin's locket, by infiltrating the Ministry of Magic. They recover the Sword of Godric Gryffindor; it is one of a few objects that can be used to destroy Horcruxes (being dipped in Basilisk venom), and they use it to destroy the locket. In their travels the trio comes across a strange symbol, which an eccentric wizard named Xenophilius Lovegood (father of Luna) tells them represents the mythical Deathly Hallows. The Hallows are revealed to be three sacred objects: the Resurrection Stone, a stone with the power to recall the dead to the world of the living; the Elder Wand, an unbeatable wand; and an infallible Invisibility Cloak.
Do you need all these names pronounced correctly? They are impossible. :)
