Long ago, there were 4 great kingdoms; The sea faring islands of Ingul, the wealthy lands of Panda, the warrior nation of Misuma, and the hardy peoples of Doningothr. These nations coexisted in relative peace, with only occasional small wars breaking out over territories.
This peace was only broke when the dark religion, The Eternal Night, began to take hold. The followers quickly spread throughout Misuma. The Misumian zealots worshiped the tyrranical god, Asmodeus, who promised great power and paradise to those who would control the entire world in his name.
As the religion began to gain power in Misuma, their armies began to strike outwards offensively, raising villages and terrorizing cities who would not follow their evil doctrine. The world was plunged into chaos as wars broke out left and right between these once perpetually stalemated kingdoms, and the Great War ensued; a war so great that speaking of it even today is enough to silence a room.
After the dust settled of the Great war, nearly every city was in ruins. There was no winner in this war, only losers. The once great leaders of their now nations of rubble met and put an end to the violence with the Great Duel. Donn of Ingul, a legendary duelist known for his panache and grace, Goff of Doningothr, a huge woman whose strength was unmatched and her unparalleled skills with an axe, Millea of Panda, a mage of extraordinary power, and Purah of Misuma, an cunning warrior with an insatiable bloodthirst. The winner of this battle was never decided, and the great rulers disappeared into legend.
1000 years later, civilization has long since returned after this catastrophe. The great war is nothing but a fairy tale at this point. Many adventurers seek to find the grounds of the Great Duel. Many dismiss this aspect of history as folklore, and that the great duel never happened in the first place. The 4 great nations are no more, now split up into smaller countries who bicker and war with each other as normal. Some countries try to expand themselves, attempting to reform their great nations together into their former glories, with little success. Most peoples, still afraid of another Great War, choose instead to expand their nations culturally.
