The narrative was posted to Rowling's website Pottermore as a Daily Prophet piece writhed by gossip journalist character Rita Skeeter.
The story finds a 33-year-old Potter attending the Quidditch World Cup final with some of his old Hogwarts classmates. Rowling, 48, has been posting a series of Quidditch World Cup pieces on her website ever since the FIFA World Cup began in Brazil in June.
The new tale also features other beloved characters from the seven-book saga like Ron Weasley, his wife Hermione Granger, Potter's wife Ginny Weasley and both couples' children.
