I like the story, it seems pretty interesting and action-packed. The plot seems good, the only thing that bothers me is that it seems a bit tedious to make in graal. I mean we can imagine it in our heads very grand but graal is pixel-art, not 3D rendering like in today's movies. I'm not saying that it's not possible, just that it's a stretch to make it look like what it sounds like. Hover bike flying over the train and trains moving through valleys would be very impressive.
