Heixinggen.
As a small town, Heixinggen has developed smoothly over the years, but local residents have suddenly found themselves growing distant from the original Heixinggen royal family. The old King Constantine traveled across the ocean, and the young prince is hardly ever in the territory—even when he returns, he mostly resides directly in the castle. Hohenzollern Castle is essentially in the suburbs of the suburbs, not even in the same place as Heixinggen town.
However, because Prussia took over the order, local citizens have gradually gotten used to this life. Now, it should be called Germany. On the day Germany was founded, the residents of Heixinggen spontaneously held a ceremony to celebrate this historic moment for the German nation.
