First of all- while the Dam is appealing, and I want to go with it eventually with our new hero- but it sends entirely the wrong message right now. Mainly, it further promotes the Valleyhome centric-view that the northern provinces resent further magnified by the fact the King doing it is already one they resent and claim is part of the problem.
No, I suggest we leverage our heroic admin and diplo to rebind the Northern provinces to us with the awesome power of rush build.
We can devote 1 secondary to building an aqueduct in Stonepen, one to policy change, and then a salt gift to the Hathathyn/expansion EH.
My point is, the number one way to reaffirm the loyalty of the northern provinces is by showing them what benefits they stand to gain from our glorious union- immediately implementing the fruits of our efforts in Valleyhome for them does that excellently and pulls them away from the Stallions.
Furthermore, it transitions Stonepen from a pastoral economy into one more resembling our heartlands.
