This is a fun game, lots of good ideas in it. So far, though, the core gameplay needs some help.
Sharing ideas a lot is spam of a single repeated power, and that's bad. This could be addressed by making it something with greater effect, but greater cost and/or time requirement; that'd remove some tedium. I also found myself with my Rise plummeting (and someone else's increasing) for reasons that weren't clear to me.
The heavy-handed ability to enthrall someone seems a bit too direct. I reckon that it would be better to have a kind of little mini-game to nab them, and it might be a good idea to make a persistent cost to keep someone directly enthralled.
This might be planned, but it seems like once the game is further along it would make sense to have a character creation bit at start, letting you pick which buildings and capabilities you get, somewhat altering the details of your goals, and giving you different numbers. In this way you might get a different power per turn (this could also be boosted by shadow, or other factors, as options purchased in character creation) which would allow you to give major things in the world (such as enthrallment) a power upkeep rate.
Buildings, I reckon, need a bit of reconceptualization. Rather than having lots of different buildings, each in only one form, it would make sense to have one or a couple buildings but to keep adding on upgrades, making (for example) a mist that is truly abominable in all ways.
I couldn't figure out how to use the military, so no feedback there other than maybe explain it better.
