. . .it would actually be not only an expansion, but also a stand-alone.
Meaning for those who already have the base game it is fully an expansion. And for those who have nothing, they can play with it.
Meaning the expansion/stand alone will contain 2 new factions, new rooms, objects, cards, order tiles, dice (so you'll have plenty with two boxes and some new game mechanics matching the new factions.)
All the main rules and rules already in the first box will remain the same to ensure total compatibility.
So. . .Looks like I wasn't too far from the mark.
And it may even be called something else!
Guess I know what my second Kickstarter will be now!!!
