Using a book shop as its cover,though they do still sell books,’underground books’ smuggles in orders taken by the students that they aren’t aloud.They deal with everything,from taking things stolen by the theifs out of the moors to be sold,giving students tattoos,even handcuffs.You name it and they most likely have,do or will do it.Just ask for a book called 'an extra pillow' and they'll take you to the back room,there you can tell them what it is you're dreaming of.
