The Quidditch World Cup 1974 tournament – better known as the “Royston Idlewind and the Dissimulators” World Cup – was played in a feverish and heightened atmosphere, following a controversial wand ban by Idlewind. The actual final was played between Syria and Madagascar, and was won by Syrian National Team. In the competition between the wizarding crowd and Royston Idlewind, the loser was Idlewind (QWC).
Idlewind made the mistake of underestimating the ingenuity of Witches and Wizards affected by an unpopular rule. It must have been a hilarious spectacle.
