There are many nations in Souland that you need to choose one to occupy and destroy other nations.

Each nation has several regions, each region has an army, and each battle must crush each other’s fortress, or destroy all soldiers in each other’s region, do one of them, then victory.

The number of soldiers in the troops is limited.
After a battle, the region will be owned by the winner. If all the regions owned by a nation were occupied, that nation is eliminated.

The battle can only be started by yourself. The other nations will not take the initiative to attack your army. However, if you win a battle, the region will be owned by you. If you fail, the region will instead be owned by each other. So you may ask for trouble by just starting a war.
