i think some one should do one about an evil overlord

Evil Overlord?

Just a bit of advice, maybe you should brainstorm your story a bit more before telling us your idea. Maybe brainstorm a basic plot synapsis like:
“Several years in the future, the world's been taken over by a ghost army and it's leader (the overlord) and mankind is nearly extince. A small group of rebels discover an anchient site that has equipment that can be used to defeat the ghosts…etc.”
