Hermione did not believe in things like auras, she’d quit Divination after all, but a chill emanated from the space. It warned of a haunted, twisted place. The abandoned house at the end of the lane you don’t dare approach on Hallowe’en. The cellar door you don’t dare open when you’re home alone. The wooded path you don’t dare cut through at night even if it would be the quickest way home. Only darkness awaited her there. In the last aisle of Malfoy Manor’s library.
