The humans were no longer the tiny ants oppressed by the variety of species in the world. They were no longer the slaves nor the food they used to be. They were no longer the weaklings, cowardly people they were.
With their more advanced technologies they reign over species. What can a werewolf do against a silver bullet? What can a giant do against missiles and rockets?
The humans were no longer called humans...they are now called Conquerors.
Hundred years of war ended as the Mage King's head fell on the floor. The sword continent took over the magic continent.
The use of magic got banned and the whole continent under was under strict surveillance.
The only hope left for the mages, sorcerers, witches, spellcasters, runemasters... are the King's offspring: The king's son and his bastard boy.
