Hagrid takes Harry to Diagon Alley, where he retrieves some of his inheritance from Gringotts, the wizard bank, and purchases his books, wand, and robes from the Leaky Cauldron and Ollivanders. At age 11, Harry is whisked away to Hogwarts by the giant gamekeeper, Hagrid, to find himself lost amongst a new world of magic and power. Head wizard Albus Dumbledore decides to have Harry grow up with the Dursleys until he is ready to attend Hogwarts, the premiere magic school in England. They were killed by the evil Voldemort, leaving Harry with a large scar on his forehead and legacy as the only wizard to escape Voldemort alive. Aunt Petunia's sister Lily married James Potter and became a powerful couple in the wizard's world.
