The Southern United Nations are the group of countries south of the Central Continent and closest to the Demon Realm.


During the Fifteen Year Human-Demon War, they were given massive aid by the Central Continent in exchange for fighting the invading demons themselves. This brought suffering and misery for the countries until the Crimson Scholar appeared and showed new ideas which brought the countries economic independence from the Central Continent. Three major Southern nations formed an alliance called the Southern Triad with exception of White Night Nation due to White Night King's arrogance and continued allegiance to the Central continent.
