Draco Malfoy was the master of the Elder Wand throughout the entirety of “Harry Potter and the Deathly Hallows.” Harry was never its master. If you think that’s far-fetched, please allow me to attempt to convince you otherwise.
When it comes to the wizarding world, there is such a thing as too much information.
“Harry Potter and the Goblet of Fire” gave us a tiny glimpse into the magical world outside of Hogwarts and British wizarding communities. We got informed impressions of Europe’s other wizarding schools—Beauxbatons and Durmstrang—as well as glimpses of other pockets of wizarding society at the Quidditch World Cup, notably the Salem Witches’ Institute.
