Expositors sound like investigators! Except we only sometimes take down rotten leaders kinda on the side... Visil was an outlier, basically.

Mostly we get sent all over to look into weird stuff or study ruins. Like, me and Simon and Raquna got sent to investigate weird noises coming from Old World ruins near a town called Etrian! And we ended up exploring the Yggdrasil Labyrinth as a result.
