I think there should way where if you research high enough of lore that you get to the point of Discovering an ancient Artifcat or Unleash an monstronsity uppon an enemy kingdom, and the game will generated that dungeon or new hidden area that was never on the map to begin with depending on what you get. Also Depending on how much you invested into that research would determine, from a small minor spell book, to an like i said eariler unleashing monstronsity, upon the land etc etc etc.

(Or is this what dungeon research is for) lol ???
