I have a theory that the name of the school—Alder Rayne University—has to be a hint. Alder is a type of tree (trees are often significant to inhuman things, BUT alder has another meaning; alder as in aldermen, so I’m thinking it’s the City/Town Council. They made the deal with the man in the rain, allowing the inhuman world nearly total access to the university, and it’s transient/temporary occupants in exchange for keeping to the university grounds, and leaving the town and faculty protected. That’s who I’m suspecting.
