I'm considering using Old Sharlayan from FFXIV as Feywood Valley, and saying there is a giant lake with a town on its shore that services the Academy, kind of similar to Hogsmeade and Hogwarts. Not sure yet, but we'll see. Here's a look at it in-game and also from the CGI trailer:

EDIT: And here is a Wiki and a greater tour of Old Sharlayan. I'm thinking the Studium can be Qrowdell Academy proper and the Noumenon can be the Library of Allandia. As for the exact layout of the Academy beyond what is shown in the video, we'll just use our imagination to say there are plenty of halls and classrooms, as well as a Dining Hall and dorms. More info on that when the main thread goes up.
