Well, the general idea (very general xD) is that it takes place on a different planet, where humans escape to after Earth is destroyed. They decide to abandon technology, and revert to a near Middle-Ages society. The world is full of mysterious things, following different rules from our world. (magic) The villain is a man who refused to give up technology, became a mechanical being (Think General Grievous from Star Wars, but with a personality more like Xehanort). He gets sealed away, and years later a group is trying to gain control of his power for their own ends. The main character, a girl named Aurora, is dragged into the conflict and... yeah. That just barely dives into it at all. xD;
