The magic of the Harry Potter world has stunned and inspired wonder in fans who've read every book, watched every movie and played every game associated with it. The halls of Hogwarts are filled with the sound of students learning how to levitate objects or fly on broomsticks. When Harry, Hermione, and Ron aren't busy battling Voldemort's malevolent Death Eaters, they have to contend with McGonagall's lectures on Transfiguration or the wailing of Mandrakes in Professor Sprout's class. The subjects each student must learn to survive in the world of magic are limitless.
