I cannot believe the polish and thought behind this faction, as it deals with some components and idea that I worked with on my own... But you developed them in such a thought out and considered way! (Not to mention that your faction pieces and the board itself would fit RIGHT in with an official expansion).
You ended up using the mechanic that's dear to my heart of some pieces "not being considered enemy pieces", but developed them in an interesting way that I kind of would have liked to see the corvids moved in. The integration of midnight actions is also top notch, even including my favourite in game action (instigate).
One thing I'm interested to see play out is how your buildings can't be battled unless the piece stacked on top is removed. That was a huge part of my own faction but I found it made my lil guys not want to get involved in conflict against the faction that was protecting them. Would be interested to see how it works out in playtesting. Also interested to see how their scoring goes in playtesting, since it revolves a LOT around other factions.
All in all, so much consideration and incredibly cool mechanics used here. Love ALL of it!
