Let me put it this way: You're dooming the entire kingdom worth of peasantry to serfdom or worse for very short term gains, one that will destroy our unique stability and potentially destroy our kingdom. Maybe not today, but centuries down the road.
I'm rather dubious of that, since that's not how real societies work.
See for example Poland post-partition, where the Polish magnates continued to treat the peasantry like dirt and the other Prussian and Austrian territories did not grow more feudal. (And see again, Poland post-partition, where feudalism was gradually undermined even in the Russian zone by economic changes, Polish liberals being liberal and the occupying powers trying to improve economic efficiency and weaken the Polish magnates.)
Where feudalism and the emiseration of the peasantry did expand, there were always one of two things pushing it: 1) weak central authority that could not push back against local magnates expanding their power and downsizing their responsibilities to other social groups (both above and below) and 2) serfdom being pushed because it was seen as progressive and efficient (see, the introduction of serfdom into Russia).
Neither of these things apply to the Ymaryn empire.
And of course, the QM might allow us to make counter-proposals to the Black Sheep. If we can peacefully assimilate them with the explicit understanding that over the next few generations Thunder Plateau will be transitioning back to the normal Ymaryn way of doing things, that's not exactly a strong precedent for would-be strong men in the rest of the empire to try and force feudal property into existence.
Now, if we can't negotiate, the balance of cost and benefit between war and peace is much closer, which is why I'm holding back from voting until the QM provides more information.
We just had the Khan rampaging through our lands, so all the damage that a war could do was done. Introduction of feudalism on the other hand, would be something that would change our kingdom for centuries at least.
As discussed above, that sounds like nonsense to me.
Maybe that's how the quest works, but I am waiting for the QM to weigh in on what the reality is.
And my concern here is that the people of Thunder Plateau - the ordinary Ymaryn people who we are ostensibly liberating - will be dying in significant numbers if we ram a million man army into the feudal overlords oppressing them. The Khan rampaging was happening in Txolla.
Yes, the OYE did that, there's just a little lack of a certain something.
We can't use the "Fire is Warm" against a population of farmers that has the same culture as us, they know our farming techniques, they know how to do all that is necessary to keep the land bountiful.
So no, Black Sheep is not a polity that can be affected by the "Fire is Warm" ie the social halping of their population to the point their population starts fleeing to us causing a social kaboom.
But... The targets aren't the farmers, the targets are the Black Sheep who have installed themselves as nobles. If we offer them a better alternative to being feudal nobles, why can't we "fire is warm" them? It's happened before.
Our Martial Hero disagree with this.
Thankyou, that's useful information.
