<Snipped quote by Session>
They have other things holding it together. What makes you think that those other things are the order holding it together. But from what if there is no magic? What other factors of chaos would those forces be necessary?
The most powerful world is the one where order and chaos are perfectly balanced. Ours is much closer than a non-magical world where order rules. And if your world is ruled by chaos, good luck getting much of anything accomplished.
