When the Northern People's Commune of Copenhagen was established, the Northern countries collectively fell into a deathly silence—too fast, the Revolutionary Army took the capital in a single day, completely erasing the entire Noble ecological system from this land. When the situation in the Western Province and the Southern Province was already settled, the resistance from the small, barren city ecological rings in the North became insignificant—even to the point where it was questionable if the Nobles in these small cities could escape this nation at all. Perhaps taking a ship would be a good idea, but after the National Fleet of the Northern Kingdom ultimately chose to rise in rebellion, it became impossible.
And in the Eastern Province... the Northern Province once had the concept of the Eastern Province, but now it possessed only a tiny amount of land, a few cats, and they have probably long been hanged at the city gates by the City Guard who have chosen to rebel.
