The library is a beauty and seems like it should be used more.
A storyline about a strange magical storm disrupting the library...It has been closed until further notice, but you have been selected to investigate and help it reopen...Upon entering rifts or gates have opened in books...questing does not close them, but stabilizes them so the library can be opened and the gates can be studied more.
A new magic school of transportation could be offered?
Could be a great portal to other worlds of classic adventures and fantasies? I am not sure how copyright would come into play, or that it would even have to if things were just alluded too, but how about the land of the giant in Jack and the Beanstalk (giant's garden with insects, giants castle, etc). Maybe a new spell school of plant and one of insects could be introduced?
I am sure other great classic settings could be suggested, and the idea of getting to them through the library could be a good lesson for children and adults alike. And still, to see that library more...it is a beauty.
