You know what Zeltiva needs especially since its the educational schoolish setting? Urban legends! Filled with ghosts, accidents and horrors which is the staple of all things like it today. I bet those academics do not like to believe in ghosts and stuff (unless the university provides spiritism classes too?) As much as I would like to say a whole haunted wing I bet they would resort to getting a ghost duster to get rid of the ghost since it will be a waste of resources so how about...a ghost librarian?
Not really a malicious one, maybe an extremely dutiful one who does not take any crap from students, staff and visitors alike abusing library privileges (and so let the horror story begin

) You could also make it mischievous if you want to add some random strange happenings like the rare lab experiment blowing up in your face, falling down the stairs, belongings being tossed into hard to reach places...
It would be funny to see students whispering things about seniors telling them to not take books into the loo in the evening, not to read while walking or something chilly will watch over you, pray to books when you drop them

Frankly even if this seems like a joke I think it will be quite useful to students who dare to befriend the ghost (especially if its an ancient one) which can teach them history and stuff. Maybe even becoming the unofficial class on its own. XD
