The moment people know his weakness; Aero could predict the chaos that would happen to the world.
It is because of that some of his behaviors and actions seems odd to people.
After all, some people wondered, why did Aero of the East, acknowledge by the world to kill forty thousand men by his lonesome rarely enter battlefield himself, preferring to strategize from the Capital?
People wonder why not just send the Chancellor to fight one wing of the enemy army and the other could be sent attacking the other?
Or better yet, send him to fight the army of the other kingdom by his lonesome. Just by sending him to a capital city, Aero could charge through the royal city and capture the king.
Aero could be considered a one-man army and his arrival into any hostile royal city could be considered a hostile action.
It would make Vanheim the most superpower nation in the continent.
