Don't You Know Nos Iam Mortui

So I haven't seen really any horror or supernatural fics in this fandom so I thought I'd give it a whirl. All of the Trix and the Winx are gonna be in it. I may include the Wizards. It'll be AU and takes place in a remote (and fake) part of Salem. The Winx are pretty much paranormal investigators (without the equipment) and they're looking to see who or what is infesting the place.
