A Brief Update:
Today Pottermore announced that, in return for winning the third House Cup, members of Slytherin House will receive early access to a unique Monstrose Magpies badge. The Montrose Magpies are “the most successful Quidditch team in British and Irish league history” in the world of Harry Potter.
Slytherins will be able to find the badge in their trunk over the next few days and it will be accompanied by an owl notifications. Members of Gryffindor, Ravenclaw and Hufflepuff will be able to collect the badge in one of the moments of the next installment of Harry Potter and the Prisoner of Azkaban.
Congratulations to Slytherin for winning the House Cup!
