A world where magic is commonplace- too common for certain people, and too powerful. This is the biggest divide:
for those that have it, it's good and necessary, and for those who don't, it's an uncontrollable danger.
Of course, most nations have a position in the middle, but still the influence of magic is felt everywhere, no matter how much people wish to oppose it.
