If an invader defeats the lord and becomes the new lord, the original lord cannot blame his own domain residents.
Because no matter how the domain residents resist, it is futile—once the Sublimator leader of the enemy is eliminated, even half-barbarians like the Mountain People would not engage in guerrilla or street warfare to the end, because once the enemy is provoked, the Sublimators will truly dig three feet into the ground to find and eliminate all 'enemies' physically.
Moreover, it is only with such a system that lords are motivated to protect 'their own' possessions.
This is an odd custom that can only be concocted in the world of Sublimators.
"There's no need for land reform at all!"
