My class suggestion: Traveler
(I think the name has already been used by someone else but i am not creative enough to come up with something else)
The Traveler is a little idea I have that is kind of inspired by the Dark Souls series.
The basic function of this class would simply be to visit other peoples worlds. The idea is that you would enter the world of an active player and just see how they are designing their village and to see their building ideas. It would also be semi awesome to see a notification that another player has decided to visit and you can see their hearthling exploring your town. Maybe there could even be a way for the traveler to open up trade, or bringing gifts, but I would be reluctant to add that due to some people maybe dropping OP weapons into new villages and therefore ruining the progression of the game. Idk, it just seems like a less complicated way of adding some form of multiplayer in the game for now.
