The Discovery of Kverka
It wasent until 2017, Kverka was discoverd by United Holy Nations. Kverka only had a population of about 50.000 and they had no official flag. There tecnology was extremely primitiv, around early middleage. After King Sander joined United Holy Nations, Kverkas tecnology increased greatly, same with there population growth. And there first official flag can you see here.
There military was far weaker then is should, but finnaly they have caught up with the rest of the world.
