The Final Siege of Hogwarts

"It was naïve of us to believe that Voldemort's death would bring about the end of the Second Wizarding War. For the Death Eaters, it was too late to slither back into the shadows like before, and their numbers were far less diminished than ours. So they fought, and our war was passed down to our children." —Hermione Weasley, Modern Magical History, "Forward" (2037, p. iv)
