The Nemecek Dynasty is the current ruling family of Krajina. They didn't intend to become the ruling family of Krajina, but they accidentally usurped a claim to the throne of Albion while trying to worm their way back in to Osterbijan polite society. Then Clachland backed their claim, specifically to fuck with Albion. One war later, and they were in charge of a country that hated them and that they had barely heard of before.

Of course, to hear them tell it, it was a brilliant end-run that had everyone fooled until the last second and they will be forever remembered as political apex predators.
