Jane was sitting in her favorite corner of the library by a window overlooking the frozen lake and vast forest reading a fascinating book about magical healing. It made modern medicine seem archaic but, unfortunately, could only be done by magical people on magical patients. So she looked up in irritation when the book drifted upwards out of her hands.
"Do you want to go exploring?" Erin asked as she lowered the book and put her wand away, with a quick glance to make sure Madam Pince hadn't seen her.
"You know we're both in danger of being withdrawn from Hogwarts," Jane reminded her. Their parents were not pleased by reports of something deadly on the third floor of the school, a break-in at the supposedly very secure bank, a troll wandering into the apparently unguarded school and a first-year student nearly falling to his death, possibly because of a cursed broomstick. But Jane loved Hogwarts. Her housemates in Ravenclaw shared her fascination with learning magic and she got to do amazing things like learning how to fly. Normal life at Hogwarts was already surprising and exciting so there was no reason to get into trouble and risk making her parents panic.
Erin pointed out that they didn't have to go to forbidden areas. The castle was so massive that, after nearly half a school year, they still kept finding unfamiliar corridors. Since there was a Quidditch match starting soon, they would not be disturbed. So Jane agreed despite misgivings. Sure enough, within several minutes, they were thoroughly lost and arguing over which way to go.
Unfortunately, that was when Peeves found them. They tried to ignore him, hoping he would find other students to bother if they weren't the only ones not watching the match. But when the poltergeist began knocking over objects, Jane worried that it was not as nonviolent as everyone seemed to think. She tried to think of a spell to chase him away but eventually resigned herself to the sensible, Muggle method and yelled, "Run."
Suddenly, they realized it was quiet aside from their footsteps and panting. They crept back to see a trail of destruction- fallen torches, singed carpets, and overturned suits of armor- leading towards them and, at the end of a long corridor, Filch scowling at the damage and walking towards them. For a moment, Jane considered explaining that they were not at fault and had skipped the Quidditch match for a perfectly innocent reason. Sighing, she nodded at Erin and they hurried away from Filch, only to find Professor Snape striding angrily along a corridor that Peeves had also damaged. There was no escape.
Frustrated, Jane began to pace, wishing she knew how to avoid getting into problems like this. Erin suddenly grabbed her arm and pointed. A door had appeared where there had not been one. With no time to think, they rushed through it. They found themselves in a small room full of bookshelves and comfortable chairs. Erin sat down with a sigh while Jane went to look at one of the bookshelves. She laughed when she found an entire section on how to ward of poltergeists. She picked a book and asked Erin to please not interrupt her with another idea for a while.
