There was once the beautiful world, Eles, with dozens of species, each with it's own god or deity. Each of these gods had its own power, and while the gods didn't get along very well, their squabbles did not erupt to fighting. In turn, the world was subjected only to minor skirmishes that often ended with little to no casualties
However, in front of the Council of the Gods appeared a faceless being, who bowed down before the gods and asked one simple question.
"I have a message for the greatest god in here, who is that god if I may ask?" he asked, knowing the disaster the question would bring.
And, with that, each god claimed that he or she was best, and what started as an argument erupted into shouting and cursing, breaking the Council apart. The only god who stood back was a god with the aspect of a child; his name was Epis. The god of games and laughter, he was an oft forgotten god by the mortals, as he was one of the few gods that did not have a species of their own.
After the shouting and arguing, the gods descended down on Eles, gathered five representatives each species to tell them who was greatest. However that did little to calm the conflict, as each species voted with their patron god. Thus, every species had unknowingly become involved in a world-destructive conflict.
The representatives went back and told their people how the other species had insulted their god and that they should be punished for their insult.
Very soon, Eles had fallen into a universal conflict that claimed the lives of tens of thousands every day. The gods weren't any different. They too started to fight and kill each other, with a god dying daily.
Epis was the only one who stood by and watched as death covered both the gods and their created species. Worried that Eles would be destroyed and all it's vast forms of life would die, he showed himself to a few individuals of each species and took them away, sealing them in his dimension until it would be safe to come out again. (note: doesn't seem to match Epis' character)
After a few months of grueling fighting, Eles fell silent, the only thing heard were the wind passing through the empty cities that were once filled with life and the sea crashing down on the shipwrecks that were once proud vessels.
The only god remaining besides Epis was Arthatros, the god War and Slaughter. However, he too was to die, for his last opponent was Dolis the Poison God. His heart started to beat slower by the second. Epis appeared before Arthatros, with a look of disgust on his face.
"You, o so great gods have succumbed to petty things that your creatures should have worried, instead you took it to heart and sought to prove that you were greatest by killing everyone else, yet now poison is coursing through your veins and you'll die because of your hubris." Epis explained. "However, my world will be a beautiful one, where people will only decide their fate by playing games and having fun."
However as Epis was talking to the dying god, the faceless being appeared again behind Epis and put a hand on his shoulder.
"Great job, Epis ,you truly are the greatest god!" He said with a tone that sent chills through Epis's body.
The faceless being, sprouting a large mouth filled with fangs, suddenly grinned.
