knockturn alley

Just around the corner from Diagon Alley lies a dark, twisting alleyway devoted to the Dark Arts: Knockturn Alley. It's a place where many children are not allowed in, and with good reason; not only are the wares sold their a bit dodgy, but the wizards hanging around behave fairly suspiciously as well. From the shops and the street vendors one can purchase, among other things, shrunken heads, poisonous candles, human-looking fingernails, and Flesh-Eating Slug Repellent.
