The quality of the books in this library is shameful. Hundreds of volumes claim to be guides to the Dark Arts, but all they contain is a few badly-spelled chapters filled with dubious incantations. Some of them mention the Unforgivables, but those are common knowledge. Others discuss bizarre-sounding hexes that could have been invented by a child. Barely any reference the Horcrux, that mysterious bit of magic that no one seems to know anything about.

Every half-wit who has read the story of Harry Potter and the late Lord Voldemort knows what a Horcrux is, but precious few know its history or how to actually create one. Dumbledore, the previous headmaster of Hogwarts, intended it to be that way. He removed all information on Horcruxes from the Hogwarts library, but made a mistake in refusing to actually burn the books. They were finally destroyed after his death, but the library's publishing standards here have become so lax that I can write a book that restates major points of the old texts (and several things I've learned from personal experience).
