@The_Philosopher the destruction of a collection of knowledge or, a library, all in the name of swabia. It sounds like you want to have a book burning, like at the library of Alexandria or the university of Louvain.
Should we kill the scholars as well, in this case that would be the people that made the guides. I know someone who is good at hacking I could talk to him and trade him my jimmy johns gift card that he is always asking to buy from me, for information on them. Once we know where they live the best course of action would be to release a wild animal into their house, such as a moose, a pack of wolves, or killer whale. That way when investigated the chief of police will say something like 'nature will be nature' laugh then probably throw the case out.
