Can anyone identify this fic?
Hogwarts is invisible(?), decaying (?), dangerous (?), abandoned
Snape is the main character.
Somehow, Snape gets inside the school, and makes his way to what used to be the Headmaster's study.
There, he awaits the end.
Sorry but you are not allowed to view spoiler contents.
I cannot find it, and it's a gem. Any help would be most appreciated.
