Turn A Gundam
This story is set thousands of years in the future. The people of Earth have forgotten the space wars of the past, reverting back to a pre-industrial existence. But the lunar settlers known as the Moonrace, who have retained their high technology, now plan to seize their mother planet for themselves. As the war of the worlds begins, a young Moonrace citizen named Loran Cehack, pilot of the legendary Turn A Gundam, struggles to bridge the gap between humanity's long-separated branches.
