It is my utmost pleasure, Mr. Widogast. You know where to find me if you need anything at all. I will scour my collection and see if I am able to find anything on the subject in particular you are interested in. Outside of that, there is always Kyteler's, also here in Everdale. As well as the Quantum Arcana and Athenaeum in Ravenmoore. The Athenaeum is an expansive library, and quite honestly breathtaking.
