Hi!
I'm positive towards the project.
I don't mind if you use dominions as a backstory for your game, but I would probably get annoyed if you did what Soywieser did in his example, changing the abysian history and adding stuff that is not there in my original setting (soywiesers dinosaurs).
Upcoming projects will not include 1500-1700 nations, so I have no objections on you going creative on what might happen in the dominions future. As long as you let me keep the past I'm totally happy. And please mention dominions so people get to know the game
As long as particular nations are not tamperd with I don't object to history stuff either. To say that the Seers of the Deep once defeated a C'tissin army advancing upon a great Ermorian port and that this ancient battlefield now have emerged from the depths after an earthquake and it is investigated by late time archaeologists of Pythium is of course fine.
If you on the other hand say that a C'tissian army led by sauromancers advanced upon Ermor with an army of shadow hierodules, the forbearers of the shadow vestals, I would be a bit annoyed, since there is no shadow hierodule in my current conception of C'tis.
