The war began with a whimper. Four separate border disputes between countries in the region eventually snowballed into a an all out war that consumed almost the entire continent of Cathagus. In the early days of the war it was mostly ever nation for itself. But as the war dragged on the number of sides became less and less as nations began taking over others and other nations began allying themselves with others. Within 3 years their was only two sides left: The Nations of the Dragon and The Alliance of the Five Stones.
Although the fighting has yet to spread past the continent of Cathagus, the rest of the civilized nations of the world have allied themselves with one side or another in the struggle. With Cathagus being the center of the modern world it only makes sense that any civilized nations would want a piece of it when the dust clears. One of these nations is New Peace.
