After Voldemort's death, a lasting era of peace begins. The heroes of Hogwarts; Harry Potter, Hermione Granger, and Ron Weasley are hired into the Ministry of Magic and Minerva McGonagall becomes the new headmistress in Hogwarts. Everything is fine for the wizards, this is their golden age.
Or so they thought...
I do not own J.K Rowling's fictional universe and characters.
