it’s the year after the war at hogwarts, everyone’s retaking their 7th year because the war interrupted last year. You are not a student at hogwarts, instead you are a guest, a celebrity singer, requested by Headmistress McGonagall to perform throughout the year for celebrations. You are staying at hogwarts for the year to perform at the dinner feasts, the yule ball, house parties, and quidditch matches.
