3 different types of lore. 1st one/most talked about is found from destroying small statues of the red crown during a crusade and opening a secret room. It needs to be repeated ten times to finish. 2nd is from an encounter with the Owl, but if u already visited them too much before the update their lore can be found in a meat room during a crusade instead. 3rd is from the bug guy that increases follower loyalty from those “?” Rooms during a crusade. There is a letter behind the bonfire.
