Alas we meet
( Aeons ago , Everlon continent )
After Hitler's death , humans became the most notorious of all races and the ' Villains' in Everlon continent.
They were the upstart race who had just discovered mana , but using trickery they removed the ability to wield mana from their opponents and won their fights in a dirty way.
However the humans crossed the line where they took in the women of the conquered races and turned them into breeding cauldrons , as soon the women of other races started to commit suicide should their town fall to humans , rather than live as a cauldron for the rest of their lives.
When things came to such a drastic point , the other species started to band together as their shared hatred for the human race made them put away their past differences in order to quell the common enemy.
Angels worked with demons and Elves worked with beastmen while even the usually aloof dragons lent a hand to exterminate humankind.
