This Quidditch World Cup tournament is better known as the World Cup of “Royston Idlewind and the Dissimulators“, following a controversial wand ban. The final match was played between Syria and Madagascar, and was won by the Syrian National Team (Pm).
Idlewind made the mistake of underestimating the ingenuity of Witches and Wizards affected by an unpopular rule.
