His first appearance was in the first book of the series, Harry Potter and the Philosophers Stone (1997) as the best friend of the protagonist Harry Potter and Hermione Granger. He is a member of the Weasley family, a pure blood family, who reside in The Burrow outside Ottery St. Catchpole. Along with Harry and Hermione, he is a member of the Gryffindor house. Ron is present in most of the action throughout the series due to his friendship with Harry.Albus Dumbledore Albus Percival Wulfric Brian Dumbledore is a fictional character, a major protagonist in J.K. Rowlings Harry Potter series. For the majority of the series, he is the headmaster of the Wizarding school Hogwarts School of Witchcraft and Wizardry. As part of his back-story, it is revealed that he is the founder and leader of the Order of the Phoenix, an organisation dedicated to fighting the main antagonist of the series, Lord Voldemort.Lord Voldemort In the series, Voldemort is the archenemy of Harry Potter, who according to a prophecy has the power to defeat him. He aims to conquer not just the Wizarding world, but the Muggle (non-magical) world as well. He is so feared that almost no one dares to say his name, instead referring to him as You-Know-Who or He-Who-Must-Not-Be-Named. Even his followers only refer to him as the Dark Lord. He was born Tom Marvolo Riddle, the last descendant of wizard Salazar Slytherin,5 one of the four founders of Hogwarts School of Witchcraft and Wizardry.Hogwarts Hogwarts School of Witchcraft and Wizardry or simply Hogwarts is a fictional boarding school of magic for witches and wizards between the ages of eleven and seventeen living in the United Kingdom and Ireland.3 It is the primary setting for the first six books of the Harry Potter series, with each book lasting the equivalent of one school year. In Harry Potter and the Deathly Hallows, however, most of the book is set outside Hogwarts as main characters Harry Potter, Ron Weasley, and Hermione Granger do not attend their final year of school (though Rowling has stated that Hermione eventually returns to school to complete her N.E.W.T. examinations).4 The climactic battle of the book, and the series, however, is set at Hogwarts.Elder Wand The Elder Wand, known throughout history as the Deathstick and the Wand of Destiny, is an extremely powerful wand made of elder wood with a core of Thestral tail hair.5 It is supposedly the most powerful wand in existence, and when used by its true master, he or she cannot be defeated in a duel; though according to Dumbledore, this is false, and the wand has been beaten hundreds of times.6 It also appears, as the wand is somewhat sentient (as are all wands), that it will not allow itself to cause real harm to its true master. As stated by Mr. Ollivander the wandmaker, the wand will never fully work for the new user unless he or she directly disarms, stuns or kills (even in Muggle fashion) the previous master.
