[@Zinita]. Question: is the world medieval or modern?  If the world has a mix of "ages" what does the academy tend to sit at?  (You put robots and elves into the CS)

I get the feeling you're going for a "let the players make it up unless it is contradictory to what has already been made" worldbuilding, which is fine, but it means we should probably keep track of all the stuff that does come up.
