Magic and Blood
In a world split by two through an impenetrable barrier, one side has access to magic and the other does not. The Twins--the two major continents that mark this world, originally torn apart from each other due to a powerful Wielder with powerful magic, Riya, the one who split the seas. Centuries after the civil war that caused the split, unrest lays in the most powerful country to the East, Rinnian. To quell that unrest, they have turned to their once-colony Bautric in the West, whose new inventions for war have caught up and exceeded their mother country.
