On the subject of themed towns, maybe a wizard's city or a major religious center (dedicated to various love gods, of course!) would work? Either one could work as a sort of scholarly town, with a major library/university/archive. A wizarding hub could be your Dalaran, your Unseen University, your Hogwarts - it might have things like moving sidewalks and an ever-present threat of being accidentally polymorphed. A religious hub, on the other hand, might range from a town that just happens to have a ton of temples to a city run by priests, and could host huge holiday celebrations or be the go-to place to find a healer.
