I just entered Industrial and am finishing up the first map- Bronze to Colonial. As far as people can tell me i won't find out what's underneath the mist in the southern section of the map with the current content in the game.
When i look at the tech tree in the game then i'm thinking that the next Age will be technology that is currently either impractical or theoretical but still plausible.
I hope that i wont find out what is under that aforementioned mist by going back to it through a time machine or somesuch
Meaning that i would rather the game stayed in the realm of serious science fiction and not the kind that turns science into magic- You have Elvenar for that
