My players and I are about three sessions in to Book 1: In Search of Sanity. They have recently reached the library and have cleared out the threats therein. Two of my players are Int based classes; a wizard and an arcanist. They both enjoy books, the wizard especially, and while they seemed pleased at the sight of a library neither is showing any interest in actually perusing the collection.
Now it doesn't seem like the information held within is crucial for completing the mod, but they will definitely miss out on some cool lore and world building stuff. The mod itself does not provide any hooks to entice research--probably because they assume anyone playing a game like this will already be interested--but I would greatly appreciate any suggestions on spurring their interest.
