Remus cursed quietly when he realized there was no section on horcruxes. He had no real idea of where to go next. The entire section of magical artifacts would be enormous-- no way he could search the entire thing. Did they have a special section on the Dark Arts here, or were those books mixed throughout? Remus realized sadly that he had no idea. He headed to the artifacts section-- QB-- and decided he would simply have to browse the shelves for anything that looks particularly Dark.
