Needs research

"Even fantasies need research. A planet in orbit around the back of the Sun? Impossible. Cometary gasses that eat metal? We know better. Earth's magnetic field preventing magic? Barely plausible, but acceptable in a pure fantasy. Of course, alien characters are harder to describe. The author has to work to make them anything but cardboard cutouts. Unfortunately, these characters are not yet three dimensional. You have the confusion and urgency of the scene of the escape from Escellion, but it needs as sense of immediacy that is lacking. Apart from the deteriorating situation, there is nothing chasing the characters, no tangible antagonist. It feels like watching a movie about ancient history, not actually being there. The time travel smacks of Deus ex Machina, but this is a fantasy, so it is forgiveable.. However, instead of the inexorable flow of events, the plot appears to be a set of unlikely constructs. This needs some more work. I apologize for a tough review. I hope some of these comments will help to improve the story. You are welcome to get even, if you are inclined."
