Use the tavern map. Conan and his friends are tasked with putting the right books back in the right chambers, where the shelves are. Whenever the event tile is used, a new pile of books is returned and pops up on the counter (on the bar).
Meanwhile, enemies (pirates?) are trying to steal books from the chambers and exit the library carrying them. instead of attacking, they can throw books around on their turn.
Sounds like a solid foundation for a fun mission!
