Welcome to the Astria Galaxy, a world filled with myths, legends and creatures of all different backgrounds and species. High above them, between the galaxy and the heavens, lies Astria; the world of living breathing color. Angels to some, protectors to others, the Astrians live as one with the universe, becoming anything it needs. Created by the Exalted One, they are the only protection between the galaxy and Sin. But how can you effectively monitor that which constantly tempts you? What happens when Sin finally breaks free... and is Unity enough to stop it?
