From the introduction:
Casting spells, a fantastical game called Quidditch, and a lightning scar are a few of the memorable things that define the world of Harry Potter. The world is once again in danger from one of the greatest Dark Wizard of all time, Lord Voldemort. A place of the imagination so real and fun which millions, both young and old, have read and re-read the books and made the films some of the biggest box office hits of all time. This is the world behind the scenes of our own, created by J. K. Rowling, where even kids can also be movers and shakers. And now you can join them with Harry Potter: The Role-playing Game! Create your own characters and go to class at Hogwarts, play a game of Quidditch, or help save your friends from a Dark Wizard... the possibilities are endless!
