From a certain standpoint, the Bardi Empire had the worst luck in this total calamity.
The Bardi Empire was indeed one of the few mega-empires on the continent. Their powerful Dragon Knight squadrons were one of their aces, and their nation had a wide area filled with abundant resources. Their mining, alchemy, equipment crafting, and other such industries were all at the forefront of the world. Plus, they had a long history, providing them with ancient inheritances and great patriotism. They also had plenty of excellently trained generals and warriors due to long periods of war, as well as a sufficient amount of cannon fodder. The Bardi Empire was incredibly solid in its foundation as a mega-empire, and possessed limitless combat potential.
