Remus scanned the shelf carefully, but nothing stuck out as particularly Dark-looking. They must have a special collection, he concluded. Remus extinguished his wand light and waited a moment for his eyes to adjust. He would have to search the entire library and its various rooms and annexes for the Dark collections, and he didn't want to risk his light being seen through the windows. Remus started, quietly but confidently, back towards the main entrance. That was, after all, where the hallways branched. Perhaps there would be a sign towards the Dark collections. In this day and age, they would not be something to hide, but rather they would be well-advertised.
