My new WIP has a problem. No protagonist. I have the entire book plotted--the whole series actually--but can't figure out what evil force is fighting against the good. Here's the premise:
Since the beginning of creation it has been foretold that a time will come when the earth will weaken and need to be mended. That time has come and there are four chosen to do the task. They are each half human, half earth spirit, each one representing one of earth's elements. Aquatara, the water spirit. Blayze, the fire spirit. Willow, the earth spirit. And Sky (not sure on this name yet), the air spirit. At the end of the series they come together to heal the earth. Their powers will combine to seal it so that the natural destruction that is taking place (earth quakes, volcanoes, etc) will stop and the inhabitants will be safe.
And here is the problem.
I don't think the natural disasters working against them is enough. I feel like there needs to be a stronger force causing these things to happen, an evil force that is working against humanity, trying to destroy the earth for its own purpose. So what is it?
Should the evil forces also be spirits? Maybe the 1/3 that chose Satan in the war of Heaven? When the world was created, were they sealed within the earth's core and they are trying to get out? Or is there a demon on the surface of the earth chasing the element spirits? As much as I struggle NOT to make this about the environment (ozone layer, pollution, etc), I'm sure there may be some of that in here, but I don't want that to be THE force against them.
I also have one more element--a fifth--that I'm weaving into the overall arc of the series, that will be revealed at the end. But it is a good element, something that will make the others' powers stronger and controllable, like the ground wire in an electrical system.
What I really need is a brainstorming session with my writing buddies. So here's your chance to be creative and give me your best. What kind of evil forces can you invent that will fit this story? I can't wait to see what you all come up with.
