Vikings can into Empire too:
The land area of the union was as large as 3,000,000 square kilometres under the rule of Margaret I of Denmark.
but wer ist de sveden?
.
What army do these handsome soldiers belong to? Can i enlist?
.Yeah, seem strange doesn't it? A large chuck of Sweden left out of the Kalmar Union? But here's why:
Nothern Sweden is cold and mountainous... not exactly prime real-estate for an aspiring empire:
No one wanted it. Not the Kalmar Union, nor Russia or anyone else. It was too cold and too inhospitable to bother with.
Not even the hardy Norsemen ventured that far north:
Northern Norway is cold, but less mountainous. Plus the water allows for swift travel by sea, That Northern Sweden was no accident.
Why China and Japan can't get along? Were you sleeping in the stone age and just woke up? I suppose many foreigners are totally clueless about the ancient relations between China,Japan and Korea to this very day. Many don't know that the modern Japanese (many of them) have Chinese bloodsince Chinese migrated to Japan and mixed with their locals since the Qin Dynasty. Chinese culture has influenced the Japanese immensely (food, writing system, clothing, architecture, garden, tea, buddhism, eating with chopsticks, weiqi, color carp breeding, art etc..) Okay the hentai,adult entertainment industry and anime have nothing to do with us
(that's typical Japanese culture, jokes aside). The cultural influence on Korea is the same, many things originated from China including the writing style until the Koreans adopted their own.
We had good relations with Japan, but Japan had tried to invade Korea few times and with the help of China we kicked the Japanese back to their island. Plus Japanese started to get arrogant and saw their empire as an equal to the Chinese empire. So yeah there were ups and downs between Chinese/Koreans with the Japanese. You have to understand Japan geographically speaking has no resources, constantly plagued by earthquakes and tsunamis. So they wanted to get on the Mainland Korea. It was during the Meiji era the Japanese went to the West and copied its tech and started to industrialize. With their militarization the Japanese tried to conquer East, South East and South Asia during WW2. The Japanese committed crimes far worse than the Nazis in China and that's the main reason why many Chinese and Koreans included dislike the Japanese. Many books and youtube videos are available of what the Japanese did so you can do your own research.
Can you enlist? Sure, hope you like whale blubber though, it's cold in the north
pen pal that's not the way to describe us, think of it as the Big Boss and his younger subordinate 
I already answered to what you said, if you can't get the message then go do your own research rather than asking ignorant question.
Pen pal i was merely describing the Sino-Japanese relation in the future that is set in the magic stone tablet
But ofcourse there was a time Japan was a subordinate of China until Japan thought of itself as the equal of China.
overall we can all agree China has always been more successful than Japan considering the size of our land, the population and the many inventions and influences of the East Asian region. Our influence was even very important to all the way to the Middle East through the famous silk road. Don't forget of the Great Zheng He who sailed all the way to Africa
