About Elements
So what do we have?
Light and dark
Air and earth?
water and fire?
Anything else?
I was thinking about the dark sun campaign from d&d. Each time a wizard cast a spell it burns a part of the world. Wouldn't it be great to have some elemental bars that would fill up each time a spell is cast. When the bar is full a portion of the world transform into an element. If a water bar is filled up then an area is flooded (and why not an area chosen from the kingdom of the player with less water affinity?). A fire bar full? an area become a desert. Light full? renewal of an area (but in the kingdom with the most affinity with light) etc...
I hope elemental will not just be about elemental creatures but also some kind of diplomacy between each one. And some balance to keep.
