There is a large magical community in Freiburg, and as such magical shops can be found just about everywhere, if a person only knows where to look. This bookshop is wedged between a Muggle coffee shop, and the headquarters for a small magazine. Muggles would just pass right by it, but a witch or wizard could slip inside and buy all the books their hearts desire. There are all subjects, including a section for the slightly darker magic in the back, behind a curtain. Not anything too explicitly illegal, of course...
