Skilled Investigator
I think one place with the greatest potential for this sort of discovery would be the continent of Antarctica. Who knows what is under the miles of ice and snow?
I think that has a great amount of potential. It could be a major miss, of course, but it seems like almost everything to be theorized about Ancient Egypt has been thought up. There's surely a lot more to figure out and not everything is necessarily right, but I think more thought needs to be paid to the rest of the world.
