In the book Harry Potter and the Deathly Hallows, they finally kill Voldemort and defeat all the Death-Eaters. Earlier however, the Death-Eaters Are winning the battle, they take over the ministry, and start saying that muggle-born’s are dangerous, and should not be allowed to use magic. Professor Snape has been appointed headmaster of Hogwarts, even though he has already killed Dumbledore. Most of the kids that are not supposed to be at Hogwarts are not; they either fled the country, or made excuses not to go. Hermione had to Obliviate (to wipe memories) her parents and use legitimacy (to change the mind) to make her parents go to Australia. Ron had to get the ghoul from the Burrows basement, give it spattergroit, and put his pajamas on it.
