After a search of the building, Cain leads his group back out to make way for the influx of visitors intrigued by the shrine to the Laughing God. There has never been one that anyone remembers, but not because of some taboo. It was simply a case of nobody really knowing what the Laughing God would like, and a temple full of practical jokes just seemed tacky and irreverent.
After all, pranks are not the essence of the Laughing God, the ability to mock fate and laugh at others' designs for you is. It's not the easiest concept to put into a shrine, so there simply wasn't one ever built.
All through the walk back to the city, Cain is immersed in thoughts of Spell Crafting, and the possibilities that lay in store for him once he manages to master the basics. They are definitely going to need a bigger space though, because he is going to need room to work and study, and the one small chair in their room isn't going to cut it.
