Sometimes The Devils Are Inside The Walls: A Harry Potter Fanfic

Warnings: I don't own HP. Rated mostly for some language. Also a little violence and some references to drug use, both relevant to the plot. And if you're a fan of Snape, he's going to be really mean in this story so you might not like it. 2 original characters, nothing really special about them.

Original characters: Liyya Morgan, Muggle Studies professor at Hogwarts and a former Ravenclaw. Cynthia Gray, Liyya's muggle friend who hides at Hogwarts under disguise as a witch when her life is in danger.

This is something I wrote several years ago when I first got into HP. I was 16 at the time and it brought back some great memories when I found and reread it. I thought it might be fun to work on it a bit, adding new stuff and finally giving it an ending. I'm hoping at least a few people get some enjoyment out of reading it!

P.S. Seeing as I was only 16 when I came up with the idea, please forgive some of the obvious holes in the plot. I know in the books muggles aren't able to see Hogwarts, but anything's possible in the land of fanfiction, right?

Intro

Sometimes it's nearly impossible to distinguish between lies and truth, and no matter how many years you've known a person, you can still find that you never really knew them at all.

It was a miserable, cold night. From outside, the massive Hogwarts Castle was almost completely obscured by heavy sheets of rain. Being just after midnight, both students and professors were asleep in their beds. The two figures that entered the castle went unseen. Their scheme would run better if they drew less attention to themselves during the initial stages.

They kept their voices down to whispers to avoid waking up the residents of the portraits or getting the unwanted attention of Filch.

"God, I'm freezing!"

"I'm sorry about this, but we need to get something straight before we go further. I need you to make a promise and it's more important than anything, even changing into dry clothes."

"Fine, anything." Their teeth chattered in the darkness.

"This is serious; I will not only lose my job and place in the wizarding world, but earn a one way trip to Azkaban if the Ministry catches wind of this. I don't even want to think of what your fate would be. You think your situation was bad before, but now you can't afford to slip up even ONCE. NOBODY here can find out that you're an outsider; promise me you'll defend that secret to your death if necessary and I'll do the same."

"You know I will" said the other figure. "Considering I'm as good as dead back home, I'll take my chances until things are sorted out."

"There's something else...The things you're about to see may be hard to process, but they're really mundane to us. You'll have to adjust fast or they'll figure it out even faster...Lumos!"

Professor Morgan lit her wand and held it low, providing just enough illumination to navigate the dark castle.
